Cryptojacking “Game” Found on Steam Store
Valve has taken recent action against an indie-developed game available on Steam, the company’s game/app store, and removed their listing after many customers had complained about cryptomining slowing their systems, once launched. Additionally, the developers have been caught selling in-game items on third-party sites, that were falsely portrayed as being items for another game in hopes of scamming more money from users. Fortunately, Valve was quick to deal with the issue and banned not only the game, but also the developers from submitting new games after their deceptive practices.
In-depth Look at Deepfakes
As special effects technology becomes more advanced, so too are those that would abuse its capabilities to cause unrest. With the release of Deepfakes, a video software that allows anyone to put any face on a body, or into a video, the power once held only by major production studios is now available to anyone with a computer. While many Deepfakes users have opted to create fake pornographic videos using popular celebrities, the software has also been used to cause political tension by falsely placing a politician’s likeness into a video with completely different audio and then distributing it as a legitimate recording.
Personal Data Easily Found by Researcher
A security researcher recently discovered a security flaw that allowed him to access personal records for over half a million customers of Fashion Nexus. While the company claims that no financial data was revealed, the personally identifiable info (PII) would be more than enough for an attacker to start committing large volumes of identity fraud. After quickly resolving the security issue, the company issued a recommendation to all customers of multiple affected e-commerce sites to change their passwords.
Google Removes Android Apps Containing Windows Malware
At least 145 Android apps have been removed from the Google Play Store after researchers discovered that they all contained malicious executables for the Windows operating system. While they will have no effect on an Android device, it still raises questions about the developer and if the system they are creating apps in has been maliciously compromised. A bigger issue would be faced if any device with an infected app was connected to a Windows computer, as the malware itself appears to focus on gathering keyboard input and searching for sensitive information stored on the system.
Yale Discovers Data Breach Nearly a Decade Too Late
After doing some vulnerability testing on several of their servers, Yale University became aware of a data breach that had occurred sometime in 2008. Even though Yale did a complete wipe of the servers in 2011, they had no idea of the previous breach and have only just begun contacting affecting alumni. Data being stored on the servers contained everything from name and physical addresses to social security numbers and birthdays, which would give any attacker significant strides towards stealing identities.
Cybercriminals are constantly experimenting with new ways to take money from their victims. Their tactics evolve quickly to maximize returns and minimize risk. The emergence of cryptocurrency has opened up new opportunities to do just that. To better understand today’s threat landscape, it’s worth exploring the origins of cryptocurrencies and the progress cybercriminals have made in using it to advance their own interests.
The FBI screen lock
Many readers may remember the infamous FBI lock malware that would pop up and prevent users from using their computer at startup. The malware presented the (false) claim that the victim had downloaded copyrighted material illegally or had watched pornography.
This was a common and successful scam that made millions globally by localizing the “official” police entity in order to legitimize the threat. The money it made was transferred via Ukash and MoneyPak, which were essentially gift cards available at local convenience stores that could be loaded with specified amounts of cash. Victims would enter the pin on the back of the card to pay the criminals.
This method of collecting money wasn’t without risks for criminals, however. If enough victims reported the scam to law enforcement, they would try to find and identify those responsible (attention criminals obviously tried to avoid).
Bitcoin and Silk Road
While the Ukash and MoneyPack scams were still alive and well, another popular and anonymous black market called Silk Road was experimenting with Bitcoin as a payment system.
Silk Road was essentially an underground market on the encrypted dark web for goods otherwise illegal or extremely difficult to purchase in most countries. The site’s buyers and sellers remained effectively anonymous to one another and were almost impossible to track. For years this marketplace thrived and proved the efficacy of Bitcoin as a transactional system. Its success came to an abrupt halt in 2013, however, when the FBI seized Silk Road and arrested its founder.
The shutdown initially caused a nosedive in Bitcoin’s market price, but it quickly bounced back to surpass its value even at the height of the Silk Road.
So, what contributed to the shift?
The first variants of Cryptolocker ransomware were seen in late September 2013. In terms of criminal business models, it was an instant success. Soon, many variants were infecting users around the world. Early editions accepted the still widely-used Ukash and MoneyPak as payment, but with a twist. Cryptolocker would provide a discount for Bitcoin payments. The proverbial Rubicon had been crossed in terms of cryptocurrencies receiving preferential treatment from cybercriminals. With ransomware rapidly rising to the top of the threat landscape, Bitcoin saw corresponding growth as fiat currencies were exchanged for it so ransoms could be paid.
Is Bitcoin Anonymous?
Not really. Since all Bitcoin transactions are recorded on a public ledger, they are available for anyone to download and analyze. Each time a victim pays a ransom, they’re given a Bitcoin address to which to send payment. All transactions to and from this address are visible, which, incidentally, is how the success of many ransomware campaigns is measured.
When a criminal wants to cash out Bitcoin, they typically need to use an exchange involving personal identifiable information. So, if a criminal isn’t careful, their victim’s Bitcoin wallet address can be tracked all the way to the criminal’s exchange wallet address. Law enforcement can then subpoena the exchange to identify the criminal. Criminals, however, are often able to keep this situation from unfolding by using tactics that prevent their “cash out” address from being flagged.
For a time, Bitcoin “mixers” offered to clean coins that were widely available on the dark web. Their methods involved algorithms that would split up and send dirty coins of varying amounts to different addresses, then back to another address clean, a process not unlike physical currency laundering. Yet, the process was not foolproof and did not work indefinitely. Once cryptocurrencies had gained significant legitimate adoption, several projects were started to search Bitcoin blockchain transactions for fraudulent activities. Chainalysis is one example.
Ransomware takes multiple cryptocurrencies
In the spring of 2014, a new cryptocurrency arrived. Dubbed Monero, it filled Bitcoin’s shoes, but without a public ledger that could be analyzed. Monero quickly became criminals’ most useful payment system to date. It uses an innovative system of ring signatures and decoys to hide the origin of the transactions, ensuring transactions are untraceable. As soon as criminals receive payment to a Monero wallet address, they’re able to send it to an exchange address and cash out clean, with no need to launder their earnings.
Monero started to see “mainstream” adoption by criminals in late 2016, when certain flavors of ransomware started experimenting with accepting multiple cryptocurrencies as payment, with Bitcoin, Ethereum, Monero, Ripple, and Zcash among the most common.
The Emergence of CryptoJacking
Monero has proven useful for criminals not just because it’s private. It also has a proof-of-work mining system that maintains an ASIC resistance. Most cryptocurrencies use a proof-of-work mining system, but the algorithm used to mine them can be worked by a specific chip (ASIC) designed to hash that algorithm much more efficiently than the average personal computer.
The original purpose of crypto-mining scripts, as described by CoinHive, was to monetize site content by enabling visitors’ CPUs to mine Monero for the site’s owners. This isn’t money from thin air, though. Users are still on the hook for CPU usage, which arrives in the form of an electric bill. While it might not be a noticeable amount for one individual, the cryptocurrency mined adds up fast for site owners with a lot of visitors. While CoinHive’s website calls this an ad-free way to generate income, threat actors are clearly abusing the tactic at victims’ expense.
We can see in the image above that visiting this Portuguese clothing website causes the CPU to spike to 100 percent, and the browser process will use as much CPU power as it can. If you’re on a newer computer and not doing much beyond browsing the web, a spike like this may not even be noticeable. But, on a slower computer, just navigating the site would be noticeably sluggish.
Cryptojacking becomes 2018’s top threat
Cryptojacking via hijacked websites hasn’t even been on the scene for a full year, and already it has surpassed ransomware as the top threat affecting the highest number of devices. After all, ransomware requires criminals to execute a successful phishing, exploit, or RDP campaign to deliver their payload, defeat any installed security, successfully encrypt files, and send the encryption keys to a secure command and control server—without making any mistakes. Then the criminals still have to help them purchase and transfer the Bitcoin before finally decrypting their files. It’s a labor-intensive process that leaves tracks that must be covered up.
For criminals, cryptojacking is night-and-day easier to execute compared to ransomware. A cybercriminal simply injects a few lines of code into a domain they don’t own, then waits for victims to visit that webpage. All cryptocurrency mined goes directly into the criminal’s wallet and, thanks to Monero, is already clean.
That’s why you should expect cryptojacking to be the preferred cyberattack of 2018.

Paired Bluetooth Devices Vulnerable to Man-in-the-Middle Attacks
A new vulnerability has been discovered that would allow an attacker to easily view the traffic sent between two Bluetooth-paired devices. The core of the vulnerability relies on the attacker’s device being within wireless range of both devices in the process of being paired. Signals from each device can then be intercepted and injected with malicious code before being forwarded to their intended destinations. Fortunately, the Bluetooth Special Interest Group has already implemented several updates so that a public-key validation is now required before pairing with a new device.
Vehicle Supplier Exposes Data for Key Car Manufacturers
A recent blunder from Level One Robotics left over 150 GB of data from several global car manufacturers on a completely unsecured server. The exposed data included factory schematics, secure request forms, and other highly sensitive information related to the assembly line process and personnel. Unfortunately, the server in question was left with public write privileges, enabling any malicious attacker to freely make changes to any of the data it contained.
Singapore Healthcare Provider Suffers After Major Data Breach
Nearly 1.5 million patients are being contacted after a data breach occurred at SingHealth, one of Singapore’s largest healthcare providers. The breach appears to have been thoroughly planned, as the high-level credentials were quickly attained after a single workstation was compromised. While no medical information was stolen, SingHealth has been reaching out to affected patients with regards to possible phishing scams that may result from the breach.
MoneyTaker Group Uses Unpatched Router to Carry Out Bank Heist
Russia’s PIR Bank recently fell victim to a rather sophisticated breach from the hacker group known as MoneyTaker, which has been responsible for over a dozen similar bank-related hacks over the past couple of years. By gaining access to the bank’s network using an outdated router, the group was able to successfully transfer portions of nearly $1 million to at least 17 different accounts before that money was withdrawn at various ATMs across the country. To make matters worse, it appears that the initial breach happened back in May, with the banks not discovering it until the day after the transfers took place.
Blackmail Scammers Cash in on Adult Site Visitors
Within the last week a campaign targeting visitors to several adult sites began making its way through thousands of email accounts. The scam focuses on scaring the victims with video captures of both their screen at the time they visited the adult site as well as video from the victim’s webcam, in hopes of extorting payments in Bitcoin. By viewing the traffic on the provided Bitcoin addresses, at least 30 individuals have paid the demanded price, gaining the scammers over $50,000 so far.
According to the Identity Theft Research Center, 2017 saw 1,579 data breaches—a record high, and an almost 45 percent increase from the previous year. Like many IT service providers, you’re probably getting desensitized to statistics like this. But you still have to face facts: organizations will experience a security incident sooner or later. What’s important is that you are prepared so that the impact doesn’t harm your customers or disrupt their business.
Although, there’s a new element that organizations—both large and small—have to worry about: the “what.” What will happen when I get hacked? What information will be stolen or exposed? What will the consequences look like?
While definitive answers to these questions are tough to pin down, the best way to survive a data breach is to preemptively build and implement an incident response plan. An incident response plan is a detailed document that helps organizations respond to and recover from potential—and, in some cases, inevitable—security incidents. As small- and medium-sized businesses turn to managed services providers (MSPs) like you for protection and guidance, use these six steps to build a solid incident response plan to ensure your clients can handle a breach quickly, efficiently, and with minimal damage.
Step 1: Prepare
The first phase of building an incident response plan is to define, analyze, identify, and prepare. How will your client define a security incident? For example, is an attempted attack an incident, or does the attacker need to be successful to warrant response? Next, analyze the company’s IT environment and determine which system components, services, and applications are the most critical to maintaining operations in the event of the incident you’ve defined. Similarly, identify what essential data will need to be protected in the event of an incident. What data exists and where is it stored? What’s its value, both to the business and to a potential intruder? When you understand the various layers and nuances of importance to your client’s IT systems, you will be better suited to prepare a templatized response plan so that data can be quickly recovered.
Visibility and business context are core requirements for a successful #incidentresponse plan. Know the key resources needed for your business’s success, and in the event of an incident, you’ll be prepared to protect your organization’s critical assets. #cybersecurity
— Gary Hayslip (@ghayslip) July 24, 2018
Treat the preparation phase as a risk assessment. Be realistic about the potential weak points within the client’s systems; any component that has the potential for failure needs to be addressed. By performing this assessment early on, you’ll ensure these systems are maintained and protected, and be able to allocate the necessary resources for response, both staff and equipment—which brings us to our next step.
Step 2: Build a Response Team
Now it’s time to assemble a response team—a group of specialists within your and/or your clients’ business. This team comprises the key people who will work to mitigate the immediate issues concerning a data breach, protecting the elements you’ve identified in step one, and responding to any consequences that spiral out of such an incident.
As an MSP, one of your key functions will sit between the technical aspects of incident resolution and communication between other partners. In an effort to be the virtual CISO (vCISO) for your clients’ businesses, you’ll likely play the role of Incident Response Manager who will oversee and coordinate the response from a technical and procedural perspective.
Pro Tip: For a list of internal and external members needed on a client’s incident response team, check out this in-depth guide.
Step 3: Outline Response Requirements and Resolution Times
From the team you assembled in step two, each member will play a role in detecting, responding, mitigating damage, and resolving the incident within a set time frame. These response and resolution times may vary depending on the type of incident and its level of severity. Regardless, you’ll want to establish these time frames up front to ensure everyone is on the same page.
Ask your clients: “What will we need to contain a breach in the short term and long term? How long can you afford to be out of commission?” The answers to these questions will help you outline the specific requirements and time frame required to respond to and resolve a security incident.
If you want to take this a step further, you can create quick response guides that outline the team’s required actions and associated response times. Document what steps need to be taken to correct the damage and to restore your clients’ systems to full operation in a timely manner. If you choose to provide these guides, we suggest printing them out for your clients in case of a complete network or systems failure.
Step 4: Establish a Disaster Recovery Strategy
When all else fails, you need a plan for disaster recovery. This is the process of restoring and returning affected systems, devices, and data back onto your client’s business environment.
A reliable backup and disaster recovery (BDR) solution can help maximize your clients’ chances of surviving a breach by enabling frequent backups and recovery processes to mitigate data loss and future damage. Planning for disaster recovery in an incident response plan can ensure a quick and optimal recovery point, while allowing you to troubleshoot issues and prevent them from occurring again. Not every security incident will lead to a disaster recovery scenario, but it’s certainly a good idea to have a BDR solution in place if it’s needed.
Step 5: Run a Fire Drill
Once you’ve completed these first four steps of building an incident response plan, it’s vital that you test it. Put your team through a practice “fire drill.” When your drill (or incident) kicks off, your communications tree should go into effect, starting with notifying the PR, legal, executive leadership, and other teams that there is an incident in play. As it progresses, the incident response manager will make periodic reports to the entire group of stakeholders to establish how you will notify your customers, regulators, partners, and law enforcement, if necessary. Remember that, depending on the client’s industry, notifying the authorities and/or forensics activities may be a legal requirement. It’s important that the response team takes this seriously, because it will help you identify what works and which areas need improvement to optimize your plan for a real scenario.
Step 6: Plan for Debriefing
Lastly, you should come full circle with a debriefing. During a real security incident, this step should focus on dealing with the aftermath and identifying areas for continuous improvement. Take is this opportunity for your team to tackle items such as filling out an incident report, completing a gap analysis with the full team, and keeping tabs on post-incident activity.
No company wants to go through a data breach, but it’s essential to plan for one. With these six steps, you and your clients will be well-equipped to face disaster, handle it when it happens, and learn all that you can to adapt for the future.
Venmo’s Public Data Setting Shows All
Researchers recently uncovered just how much data is available through the Venmo API, successfully tracking routines, high-volume transactions from vendors, and even monitoring relationships. Because Venmo’s privacy settings are set to public by default, many users have unknowingly contributed to the immense collection of user data available for all to view. In addition to purchases, users can also leave a personalized note for the transaction, some of which range from drug references to more intimate allusions.
This is a great piece with real insight into what people take for granted on social platforms. I’m sure many of the accounts profiled had no idea that so much of their transaction information was public and searchable by default. https://t.co/qEzdkahGAZ #privacy

Spanish Telecom Suffers Major Data Breach
One of the world’s largest telecom providers fell victim to a data breach this week that could affect millions of Movistar customers. The breach allowed current customers to access the account of any other customer, simply by altering the alpha-numeric ID contained within the account URL. While parent company Telefonica was quick to resolve the issue, the communications giant could be forced to pay a fine upwards of 10 million EUR for not complying with new GDPR rules.
DDoS Attacks Target Gaming Publisher
Yesterday, Ubisoft announced via Twitter that they were in the process of mitigating a DDoS attack affecting many of their online gaming servers. At least three of Ubisoft’s largest titles were affected, leaving thousands of players unable to connect to online services. While Ubisoft has likely resumed normal activity, they are not the only gaming publisher to be the focus of these types of attacks. Blizzard Entertainment suffered a similar attack as recently as last week.
ProCare Health Under Fire for Patient Info Database
At least four companies handling the IT needs of the healthcare system in New Zealand have come forward to disclose an extremely large database containing of identifiable information (PII) for more than 800,000 patients. The database in question holds records for many thousands of patients, most of which were gathered without consent from patients, as the company has no direct dealings with them, but instead works with doctors to accumulate more data. While having such a large volume of data in one place can be risky, the security measures should equal the value of the data itself, which is still under scrutiny.
South Korea No Longer Main Target of Magniber Ransomware
Researchers have noticed over the past few weeks a significant trend involving the Magniber ransomware variant branching out from its long-time focus on South Korea to other Asian countries. Additionally, the source code itself has been vastly improved and has begun using an older exploit for Internet Explorer that would allow Magniber to increase infection rates across unpatched systems.
While one-click shopping on Amazon (or Webroot.com, for that matter) seems super easy when you’re the consumer, there are a lot of complex strategies and processes going on behind the scenes.
We chat with Cathy Ondrak, product owner for Webroot.com, to get a glimpse behind the curtain. In her role, Cathy works with developers, business analysts, and other stakeholders on a daily basis to ensure Webroot customers’ needs are being met online.
Tell us a bit about yourself.
I have three amazing kids—ages 9, 11, 13. We’re just getting to the teen years, which scares me to death. When I’m not working, I’m probably ushering my kids to one of their various activities. My life revolves around them; from baseball, softball, and soccer to basketball, parkour, or art activities, they stay busy and keep me on my toes. I also lead my nine-year-old’s Girl Scout troop and participate in my kids’ school accountability committee (SAC) meetings.
I was born in North Carolina (go Duke!) My parents moved us to Aurora, Colorado when I was a year and a half old. They still live in my childhood home. My sister and her family live about 2 miles from me, so you can regularly find my family attending one of the grandkids’ activities. (We travel in a large pack, and our kiddos always have a cheering section.)
How did you get into tech?
I began my career in public relations, moved to marketing, then product management. I worked on bringing US WEST Wireless to market a long time ago, which was my entry into tech. While at US WEST, I managed their website and eventually moved into a product manager position for their first wireless internet solution, BrowseNow. It was a very exciting time, but nothing like things are now. Everything was text-based, black and white, and not even a little pretty.
What does a day in your life at Webroot look like for you?
As the product owner for Webroot.com, I’m constantly checking emails, attending meetings, and collaborating with various internal teams. Beyond that, I oversee the web developers’ work and stay in constant communication with them. I work with developers, business analysts, and stakeholders daily to ensure deadlines are met and projects are completed as quickly as possible. We work in an agile environment, so we try to deliver solutions quickly and enhance as we need to. It’s pretty exciting to see the changes over the years when you have time to look back.
Why do you like working at Webroot?
The thing I like best about Webroot is the people. Working with driven and intelligent people make what we do great and make me value the relationships I’ve formed. The other thing would be watching the continued success of the teams as we grow. The amount of work that flows through our team each day is amazing. The most rewarding thing is seeing how far we’ve come since we started! It’s inspiring to witness whole organization working together to bring new products to market.
Do you interface with external customers?
My day-to-day is filled with internal customers and teams at Webroot—mostly marketing teams who work with us to enhance the website and online user experience, and also provide more flexibility to sell our products.
Any advice for other women in tech?
The only advice I have applies to everyone, regardless of field or gender: do what you love, value the people, and success will come naturally. We all have control of our own outcomes, so be open, honest, and flexible. And for other Webrooters reading this, attend the Women of Webroot meetings, get to know your fellow colleagues, and enjoy every minute of it!
What’s the biggest lesson you’ve learned from working in the field?
My biggest lesson from the field was something someone told me years ago for when you’re trying to solve problems or work with developers. Ask yourself, “What are 3 possible solutions to anything you are doing?” Having options ready helps you think things through, so you can evaluate multiple possible solutions to determine which one is the most viable for your situation and resources. Options are key.

Ticketmaster Snafu Only Tip of the Iceberg
After last month’s Ticketmaster breach, a follow-up investigation found it to be part of a larger payment card compromising campaign affecting more than 800 online retail sites worldwide. The cause of the breach appears to stem from the third-party breaches of several Ticketmaster suppliers, which allowed hackers to integrate their own code within the software to compromise a far larger audience than originally realized.
Adobe Issues Patches for Over 100 Vulnerabilities
This month’s Patch Tuesday for Adobe introduced more than 100 unique fixes for vulnerabilities related to both Acrobat and Reader. Among the patches are fixes for unauthorized read issues that were allowing for the disclosure of sensitive information. Additionally, a patch was released for Flash Player that resolved a flaw allowing for unauthorized remote code execution, which could have had resulted in serious harm to any affected system.
Fitness Tracker App Reveals Locations of Military Personnel
Fitness app Polar Flow has recently come under scrutiny after the identity and locations of thousands of military personnel were easily revealed using the fitness map functionality. By displaying the activity map, users were could be traced to highly secretive locations, such as the White House and several other military bases around the world. The issue was caused by users swapping between public and private sessions closely tied to their individual user ID numbers when tracking fitness activities within the app.
Rahkni Ransomware Now Comes with a Choice
A longtime ransomware variant known as “Rahkni” was recently spotted in the wild with new functionality. The latest update has allowed Rahkni to decide between completely encrypting a system and deploying a crypto-miner. While mainly targeting Russian users, the ransomware is spread through malicious email attachments posing as a legitimate version of Adobe. In addition to its main operations, Rahkni also completes a thorough system scan and checks for virtualization and antivirus software before shutting down any OS-based defenses.
Chinese Hackers Compromise Australian University
After months of fending off cyberattacks, the Australian National University finally fell victim to a major data breach that has since been traced back to China. While the university believes that no student or staff information was stolen, the university serves as the main location for several national defense research organizations. This attack comes shortly after Australia implemented multiple new laws designed to reduce foreign intrusion.
With cybercrime damages set to cost the world $6 trillion annually by 2021, a new bar has been set for cybersecurity teams across industries to defend their assets. This rings especially true for IT service providers, who are entrusted to keep their clients’ systems and IT environments safe from cybercriminals. These clients are typically small and medium-sized businesses (SMBs), which are now the primary target of cyberattacks. This presents a major opportunity for the managed service providers (MSPs) who serve them to emerge as the cybersecurity leaders their clients rely on to help them successfully navigate the threat landscape.
Before you can start providing cybersecurity education and guidance, it’s crucial that you become well-versed in the biggest threats to your clients’ businesses. As an IT service provider, understanding how to prepare for the following cyber threats will reinforce the importance of your role to your clients.
Ransomware is a type of malware that blocks access to a victim’s assets and demands money to restore that access. The malicious software may either encrypt the user’s hard drive or the user’s files until a ransom is paid. This payment is typically requested in the form of an encrypted digital currency, such as bitcoin. Like other types of malware, ransomware can spread through email attachments, operating system exploits, infected software, infected external storage devices, and compromised websites, although a growing number of ransomware attacks use remote desktop protocols (RDP). The motive for these types of attacks is usually monetary.
Why is ransomware a threat that continues to spread like wildfire? Simple: it’s easy for cybercriminals to access toolsets. Ransomware-as-a-Service (RaaS) sites make it extremely easy for less skilled or programming-savvy criminals to simply subscribe to the malware, encryption, and ransom collection services necessary to run an attack—and fast. Since many users and organizations are willing to pay to get their data back, even people with little or no technical skill can quickly generate thousands of dollars in extorted income. Also, the cryptocurrency that criminals demand as payment, while volatile in price, has seen huge boosts in value year over year.
Tips to combat ransomware:
- Keep company operating systems and application patches up-to-date.
- Use quality endpoint protection software.
- Regularly back up company files and plan for the worst-case scenario: total data and systems loss (consider business continuity if budgets allow).
- Run regular cybersecurity trainings with employees and clients.
Phishing is the attempt to obtain sensitive information, such as usernames, passwords, and credit card details (and, indirectly, money), often for malicious reasons. Phishing is typically carried out by email spoofingor instant messaging, and it often directs users to enter personal information into a fake website, the look and feel of which are almost identical to a trusted, legitimate site.
Phishing is a common example of a social engineering attack. Social engineering is the art of tricking or manipulating a user into giving up sensitive or confidential information. The main purpose of a phishing attack can range from conning the recipient into sharing personal or financial information, to clicking on a link that installs malware and infects the device (for example, ransomware uses phishing as its primary infection route.)
Tips to combat phishing:
- Ensure your employees and clients understand what a phishing email looks likeand how to avoid becoming a victim by testing your users regularly. Train them with relevant phishing scam simulations.
- Hover over URLs in email to see the real address before clicking.
- Use endpoint security with built-in anti-phishing protection.
- Consider a DNS filtering solution to stop known phishing and malicious internet traffic requests.
Brute Force Attack
A brute force attack is a cyberattack in which the strength of computer and software resources are used to overwhelm security defenses via the speed and/or frequency of the attack. Brute force attacks can also be executed by algorithmically attempting all combinations of login options until a successful one is found.
It’s important to note that brute force attacks are on the rise. Earlier this year, Rene Millman of SC Magazine UK reported, “hacking attempts using brute force or dictionary attacks increased 400 percent in 2017.”
Tips to combat brute force attacks:
- Scan your systems for password-protected applications and ensure they are not set to default login credentials. And if they’re not actively in use, get rid of them.
- Adjust the account lockout policy to use progressive delay lockouts, so a dictionary or brute force combination attack is impossible.
- Consider deploying a CAPTCHA stage to prevent automated dictionary attacks.
- Enforce strong passwords and 2-factor authentication whenever possible.
- Upgrade your toolset. RDP brute force is a major ongoing issue. Standard RDP is highly risky, but secure VPN paid-for alternatives make remote access much more secure.
Leveraging Common Cyber Attacks to Improve Business
As an IT service provider, it’s important to remember that communication is everything. With clients, I recommend you define what exactly you’re protecting them against in an effort to focus on their top cybersecurity concerns. If you “profile” certain attack vectors using common attacks types, like ransomware, phishing, and brute force attacks, you’ll be able to clearly communicate to clients exactly what it takes to protect against their biggest risks and which technologies are necessary to remain as secure as possible.
Canadian college breach targets thousands
Last Friday, Algonquin College officials announced that an earlier data breachpotentially affected thousands of current and former students, as well as employees. While it is still unclear exactly what systems were affected, the officials have been working to contact all potential victims and inform them of the situation. What’s more interesting is Algonquin’s CISO’s comment in the article. You’d think that after the university’s first attack in 2014, they would have been better prepared this time around. At the very least, they could address the measures you’ve taken and plan on taking moving forward to prevent breaches.
Tinder implements major security upgrades
Tinder recently introduced fixes for two security vulnerabilitiesrelating to pictures insecurely stored on their servers and the ability to encrypt swipe responses. Those are pretty big vulnerabilities, considering Tinder has more than 50 million active users. The first fix involved Tinder securing their storage servers to keep hackers from accessing them through an unsecured WiFi network. The second fix revolved around making all swipe data the same size, as that was the differentiating factor between “likes” and “dislikes.”
Exactis data leak exposes info on 340 million users
A Florida-based marketing firm is currently under fire after the data for over 340 million customers was found on a publicly accessible server. It has not yet been determined for how long the information was publically accessible. The article title reads “Worse than Equifax.” I’d say. That’s all of America. Fortunately, Exactis was quick to lock down the server once they were alerted to the exposure. It has been confirmed that the data includes everything from names and addresses to types of pets and specific religious affiliations.
Adidas website falls victim to hackers
Adidas’ US website was breached this week, with sensitive data for millions of customers being stolen by unknown hackers. The company has since confirmed that no payment card information was included in the leak, only site usernames and passwords, which Adidas did properly store with strong levels of encryption. The company is still suggesting anyone who has ever made purchases from their website to change their password, regardless of whether it has been used for other sites or not. Take this as an opportunity to update all of your passwords—especially passwords on sites that you use as the same for your Adidas account.
Ticketmaster waits months to reveal data breach
Ticketmaster United Kingdom has finally released a breach statementmonths after Monzo bank, a UK-based mobile bank, informed the tickets sales giant of dozens of fraudulent charges. Even after being informed, the company wasn’t able to properly identify any data breach for over 2 months. I guess the bright side is that Ticketmaster has begun offering identity monitoring services to affected customers.
Weaponized USB Drives Targeting Japan and South Korea
In an effort to target air-gapped internal systems, a new wave of weaponized USB drives has been found throughout Japanese and South Korean organizations. While these attacks are relatively uncommon, that only heightens the threat as most companies are ill-prepared for such an attack and have created their air-gapped network systems in hopes of deterring them. As the systems utilizing this security method are typically extremely sensitive, this type of attack becomes increasingly focused on organizations or industry processes.
Hotel Booking Software Compromised
This week, officials for FastBooking, a Paris-based software companythat sells booking software to hundreds of hotels around the world, announced they had fallen victim to a data breach. The actual breach occurred over a week ago, and it took FastBooking employees nearly a week to discover the malicious software running on their servers. Unfortunately for customers, the data stolen seems to vary from hotel to hotel, as they all store data differently. The breach could affect millions of clients worldwide.
PythonBot Delivers Ads and Cryptominers to Windows Users
Researchers have recently discovered a new adware variant,written exclusively in Python, that not only spams your device with various ads, but also installs a cryptominer on the system for added financial gain. Ads are displayed by PBot using a malicious browser extension that attempts to redirect users to revenue-generating ad sites. In addition to its malicious activities, PBot also contains functionality to constantly receive updates to stay a step ahead of security software trying to remove it.
Flight-tracking Service Suffers Data Breach
Over the last few days, FlightRadar24, one of the largest flight tracking servicesin the world, suffered a data breach that could affect all of its 230,000 users. The breach only contained email addresses and hashed passwords, with the company swiftly pushing out password reset links to all affected customers along with disabling all current passwords. Fortunately, this breach contained no other personally identifying information or payment card data.
Nintendo Switch Hacked After DevMenu Leak
Recently, users of the Nintendo Switch have discovered illicit photos being used as profile pictures within games targeted at younger players. After an internal developer menu for the Switch was leaked, users could upload any small JPG file to an SD card and use the menu to change the avatar picture to anything they choose, including pornographic images. Unfortunately, Nintendo doesn’t currently moderate user profile pictures, but will likely have to make some changes if this behavior continues.
We’ve seen some tricky techniques used by cybercriminals to distribute malware through social media. One common threat begins with a previously compromised Facebook account sending deceptive messages that contain SVG image attachments via Facebook Messenger. (The SVG extention is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation.)

If a you were to install this extension, it will take advantage of your browser access to your Facebook account to secretly mass-message your friends with the same SVG image file—like a worm, this is how it spreads. Victims don’t need to have very many friends for this tactic to be successful at propagating. For instance, if you have over 100 friends, then you only need less than 1% of your friends to fall for this for the scam for it to continue to propagate.
To make matters worse, the extension also downloads Nemucod, a generic malware downloader generally used to download and install a variety of other threats. Usually the go-to threat is ransomware given it’s proven business model for criminals.
Social media managers at risk
Those who manage social media accounts on behalf of businesses are particularly at risk of advanced malware and other cyberattacks. Earlier this spring, a new Windows trojan dubbed Stresspaint was found hidden inside a fake stress-relief app and likely spread through email and Facebook spam campaigns to infect 35,000 users, according to researchers at Radware who discovered the malware.
Stresspaint was rather deviant in the way it stole Facebook account credentials and logged into accounts looking specifically for data such as “each user’s number of friends, whether the account manages a Facebook Page or not, and if the account has a payment method saved in its settings,” according to Bleeping Computer.
Allowing cybercriminals to gain control of brand social media accounts can carry grave consequences such as reputation damage, loss of confidential information, and deeper access into an organization’s network. Last year, HBO was humiliated on their social profiles when the notorious hacker group OurMine breached several the network’s accounts and posted messages before the company finally regained control of their logins.

Crypto users targeted
Following the recent trend in malware, sophisticated variants of existing strains are now aimed at cryptocurrency users. A malicious Google Chrome extension called FacexWorm, which spreads through Facebook Messenger, was found to have morphed with a new ability to hijack cryptocurrency transactions made on a host of popular online exchanges, according to Coindesk. This further underlines the importance of exercising caution with the information you share on social media to avoid being a target, particularly if you are a user of cryptocurrency.
Cryptocurrency scams are another common threat that spreads throughout social media. Twitter is particularly notorious an outbreak of crypto scam bots that pose as high-profile tech leaders and industry influencers. Learn more about this type scam in my previous post.
Don’t let your guard down
Given the nature of social networks, many are likely to consider themselves to be in the company of friends on sites like Facebook, Instagram and Twitter. However, this assumption can be dangerous when you begin to trust links on social sites more than you would in your email inbox or other websites. For instance, a simple bot-spam message on Twitter was able to grant a hacker access to a Pentagon official’s computer, according to a New York Times report published last year.
It’s wise to be wary of clicking on all links, even those sent by friends, family or professional connections, as compromised social media accounts are often used to spread scams, phishing, and other types of cyberattacks. After all, just one wrong click can lead to an avalanche of cyber woes, such as identity theft, data loss, and damaged devices.

I had the privilege of giving a keynote on one of my favorite topics, busting myths around artificial intelligence (AI) and machine learning (ML), during DattoCon 2018 this week.
Webroot has been doing machine learning for more than a decade and consider this aspect one of our key differentiators for our solutions. However, for many small and medium-sized businesses (SMBs), that might not matter. They may have heard the terms AI or ML but aren’t sure how these advancements can help keep their company safe. Additionally, the managed service providers (MSPs) who provide millions of SMBs with security protection, might not know how this technology can help their customers either.
AI and ML are not the same thing. Marketing campaigns and news articles oftentimes confuse people into thinking that they are—and my insistence on clarifying their nuance might be overkill—but I think it’s important to know the difference so you can understand how each can help make cybersecurity stronger.
What is artificial intelligence?
Artificial intelligence interacts with people, whether emulating a human (think about chat bots) or pets. The AI component is that interactive component—the thing you can touch, feel, and see. AI technology is very nascent, and I expect great things to come in the near future.
What is machine learning?
Machine learning is artificial intelligence’s nerdy cousin. ML models are designed to analyze all of the data collected, behind the sciences, with no human interface. ML is the heavy science where all the data crunching takes place. This is the part of technology that a few companies, like Webroot, have been working in for a long time.
To dig in further, I decided to take to the streets (or aisles) of DattoCon 2018 in Austin, TX, and see what MSPs were hearing and thinking about in relation to AI and ML. I kicked things off by getting a grasp on what MSPs are being asked by their customers.
“Absolutely nothing,” said Steven Gomes, kloudfyre. “They don’t bring it up; it’s nothing I even talk about. I know AI is the future of processing speed and power — so it’s important to me because it means accuracy and intelligence. But my customers don’t ask.”
That’s the response I got across the board. MSPs know it is something key for the future of security, but their customers don’t ask about it at all. I’m heartened to learn MSPs understand the importance, but can they tell marketing hype from reality? I want to make sure they understand what’s important or key differentiators for AI and ML.
Identifying the problem, data and consumability are key.
First, you need to know what problem you’re trying to solve before you can engage ML models. Next is having substantial data to feed the models. Webroot analyzes 500 billion data elements a day that we link and push through our models to enhance our analysis. We have a lot of access to information that new players in the space simply do not. Data is key to training up a model. Finally, consumability is getting the ML models into the hands of the customer so that the solution can be actionable. It’s pretty easy to tune new models, but it’s not easy to get the models deployed and allow customers to get meaningful, actionable data from it.
What do MSPs hear from customers around what’s key with ML?
The general sentiment was that it’s a checkbox in that they know the words, and it’s a must, but there is no real data or understanding of the why. SMBs don’t know what it means or how it applies to their business other than making security generally better.Going one-step further, I get concerned people are enamored with the idea of the tech but not clear on the value it can provide.
AI and ML should help in three areas for customers.
First, it should help create new capabilities for the security stack while at the same time decreasing their costs and reducing their cycle time to detect and remediate threats. Second, it should help detect emergent, unexpected threat behaviors quickly enabling the security team or an orchestration solution to take action. Third, it should deliver value around people augmentation. It could be automation of remedial tasks or simply working around the clock while your human employees go home and sleep.
“MSPs are technologists. They have to take complex stuff for their clients and their clients have blind faith. So MSPs focus on effectiveness.” -Cameron Stone, sales, Webroot
When I dug in more about benefits, a recent MSP owner chimed in, “Almost all decisions are based on whether it reduces headaches and is an innovative tool for my customers; so if machine learning does that, I’m all for learning more. I’d be happy to read up on it, but my customers don’t have time to read or care about it.”
As a passionate fan of ML, I realized there is a lot more we in the industry need to do to help educate and make this technology easy to consume.
Machine learning’s super power is that the amount of data it can take it has no limits. Think about it the context of healthcare: what if the best doctors in the world could work on your issue, around the clock? ML can provide that value to cybersecurity.
I appreciate Datto letting me talk on my soapbox for a few minutes and hope to continue this conversation with more MSP partners.
