Context Matters: Turning Data into Threat Intelligence

1949, 1971, 1979, 1981, 1983 and 1991. Yes, these are numbers. You more than likely even recognize them as years. However, without context you wouldn’t immediately recognize them as years in which Sicily’s Mount Etna experienced major eruptions. Data matters, but only...

A Chat with Kelvin Murray: Senior Threat Research Analyst

Reading Time: ~ 3 min.

In a constantly evolving cyber landscape, it’s no simple task to keep up with every new threat that could potentially harm customers. Webroot Senior Threat Research Analyst Kelvin Murray highlighted the volume of threats he and his peers are faced with in our latest conversation. From finding new threats to answering questions from the press, Kelvin has become a trusted voice in the cybersecurity industry.

What is your favorite part of working as a Senior Threat Research Analyst? 

My favorite part about being a threat researcher is both the thrill of learning about new threats and the satisfaction of knowing that our work directly protects our customers. 

What does a week as a Senior Threat Research Analyst look like? 

My week is all about looking at threat information. Combing through this information helps us find meaningful patterns to make informed analysis and predictions, and to initiate customer protections. It roughly breaks down into three categories. The first would be “top down” customer data like metadata. The data we glean from our customers is very important and a big part of what we do. The interlinking of all our data and the assistance of powerful machine learning is a great benefit to us.  

Next would be “whole file” information, or static file analysis and file testing. This is a slow process but there are times when the absolute certainty and granular detail that this kind of file analysis provides is essential. This isn’t usually part of my week, but I work with some great specialists in this regard.  

Last would be news and reports on the threat landscape in general. Risks anywhere are risks everywhere. Keeping up to date with the latest threats is a big part of what I do. I work with a variety of internal teams and try to advise stakeholders, and sometimes media, on current threats and how Webroot fits in. Twitter is a great tool for staying in the know, but without making a list to filter out the useful bits from the other stuff I follow, I wouldn’t get any work done! 

What skills have you built in this role? 

Customer support taught me a lot in terms of the client, company culture, and dealing with customer requests. By the time I was in business support I was learning the newer console system and more corporate terms. Training on the job was very useful for my move to threat, where I also picked up advanced malware removal (AMR), which is the most hands on you can get with malware and the pain it causes customers. All of that knowledge is now useful to me in my public facing role where I prepare webinars, presentations, interviews, blogs, and press answers about threats in general. 

What is your greatest accomplishment in your career at Webroot so far? 

Learning the no-hands trick on the scooter we have in the office. And of course my promotion to Senior Threat Research Analyst. I have had a lot of different roles in my time here, but I’m glad I went down the path I did in terms of employment. There’s never a dull moment when you are researching criminal news and trends, and surprises are always guaranteed. 

What brought you to Webroot? 

I like to say divine providence. But really I had been travelling around Asia for a few months prior to this job. When I got back home I was totally broke and needed a job. A headhunter called me up out of the blue, and the rest is history.   

Are you involved in anything at Webroot outside of your day to day work? 

Listening, singing and (badly) dancing to music. Dublin is a fantastic place for bands and artists to visit given its proximity to the UK and Europe and the general enthusiasm of concert goers. I do worry that a lot of venues, especially nightclubs, are getting shut down and turned into hotels though. I sing in a choir based out of Trinity College.  

Favorite memory on the job? 

Heading to (the now closed) Mabos social events with my team. The Mabos collective ran workshops and social and cultural events in a run-down warehouse that they lovingly (and voluntarily) converted down in Dublin’s docklands. Funnily enough, that building is now Airbnb’s European headquarters. 

What is your favorite thing about working at Webroot? 

The people that I get to work with. I have made many great friendships in the office and still see previous colleagues socially, even those from five or six years ago.  

What is the hardest thing about being a Senior Threat Research Analyst? 

Prioritizing my time. I can try my hand at a few different areas at work, but if I don’t focus enough on any one thing then nothing gets done. I find everything interesting and that curiosity can get in the way sometimes! 

What is your favorite thing to do in Dublin?  

Trying new restaurants and heading out to gigs. I’d be a millionaire if I didn’t eat out at lunchtime so much. Dublin is full of great places. I like all kinds of gigs from dance to soul to traditional. The Button Factory is one of the coolest venues we have. 

How did you get into the technology field? 

I first become interested in technology through messing with my aunt’s Mac back in the early 90s. There were a lot of cool games on her black and white laptop she brought home from a compucentre she worked in, but the one that sticks in my memory was Shufflepuck Café. My dad always had some crazy pre-Windows machines lying around. Things with cartridges or orange text screens running Norton commander.

Cyber News Rundown: Banking Trojan Closes Ohio Schools

Reading Time: ~ 2 min.

Banking Trojan Shuts Down Ohio School District

After the discovery of the banking Trojan known as Trickbot, an Ohio school district was forced to cancel school since they were unable to fully disinfect the networks before classes resumed the following Monday. Preliminary reports have concluded that no students were responsible for the attack, as it appears to have started its data-gathering on a computer belonging to the district treasurer’s office. In order for classes to resume normally, the IT staff for the district had to re-format nearly 1,000 affected computers. 

GetCrypt Spreading Through RIG Exploit Kits

Another ransomware variant, GetCrypt, has been spotted in the wild that spreads itself across systems by redirecting visitors to a compromised website to a separate page hosting an exploit kit. After checking for several Eastern European languages, the ransomware begins encrypting all files on the system and displays a standard ransom note. In addition to removing all available shadow copies from the computer, GetCrypt also appends all encrypted files with a randomized, four-character string based on the CPUID of the device itself.

Google Assistant Logs All Online Purchases

It was recently discovered that Google’s Assistant, released last year, keeps a log of all online purchases for which a receipt was sent to the user’s Gmail account. The “Payments” page on a user’s Google account shows transactions, flight and hotel reservations, and other purchases made up to several years prior, even showing the cost, date, and time of the purchase.

Forbes Joins List of Magecart Victims

It was revealed late last week that Forbes had fallen victim to a Magecart attack possibly affecting anyone who made a purchase on the site during that time. Fortunately, the researcher who discovered the attack quickly notified both Forbes and the domain owner, resulting in a swift removal of the malicious payment card skimmer from the highly-trafficked site. It’s likely that Forbes became a victim after another vendor in their supply chain was compromised.

Australian IT Contractor Arrested for Cryptomining

An IT contractor working in Australia was arrested after being caught running cryptomining software on government-owned computers, which netted him over $9,000 in cryptocurrency. The charges encompass misuse of government systems by making modifications to critical functions and security measures for personal gain while in a position of trust. By making these changes, this contractor could have exposed a much larger portion of the network to malicious actors who take advantage of misconfigured settings to access company data.

Cyber News Rundown: WhatsApp Vulnerability Could Install Spyware

Reading Time: ~ 2 min.

WhatsApp Exploited to Install Spyware through Calls

A serious flaw has been discovered in the messaging app WhatsApp that would allow an attacker to install spyware on a victim’s device by manipulating the packets being sent during the call. Further disguising the attack, the malicious software could be installed without the victim answering the call, and with access to the device the attacker could also delete the call log. Fortunately, the Facebook-owned app was quick to respond and quickly released an update for affected versions. 

SIM Swapping Group Officially Charged

Nine men in their teens and 20s have been arrested and charged for a SIM-swapping operation that netted the group over $2 million in stolen cryptocurrency. The group operated by illicitly gaining access to phone accounts by having the phone swapped to a SIM card in their control. The group would then fraudulently access cryptocurrency accounts by bypassing 2-factor authentication, since login codes were sent to devices under their control. Three of the group were former telecom employees with access to the systems needed to execute the scam.

Web Trust Seal Injected with Keylogger

A recent announcement revealed that scripts for the “Trust Seals” provided by Best of the Web to highly-rated websites were compromised and redesigned to capture keystrokes from site visitors. While Best of the Web was quick to resolve the issue, at least 100 sites are still linking customers to the compromised seals. This type of supply chain attack has risen in popularity recently. Hackers have been seen injecting payment stealing malware into several large online retailer’s websites since the beginning of the year.

Fast Retailing Data Breach

The online vendor Fast Retailing is currently investigating a data breach that gave attackers full access to nearly half a million customer accounts for two of the brand’s online stores. The attack took place within the last three weeks and targeted payment information with names and addresses for customers of UNIQLO Japan and GU Japan. Fast Retailing has since forced a password reset for all online customers and delivered emails with further information for those affected by the attack.

Data Leak in Linksys Routers

Last week researchers discovered a flaw in over 25,000 Linksys routers that could give attackers access to not only the device’s MAC address, but also device names and other critical settings that could compromise the security of anyone using the router. Additionally, by identifying the device’s IP address, attackers could even use geolocation to gauge the approximate location of the exploited device, all without authentication.

Cyber News Rundown: Dharma Diversion

Reading Time: ~ 2 min.

Dharma Ransomware Employs Diversion Tactics

Researchers recently discovered a new ransomware variant that displays an ESET AV removal screen once launched in order to divert the a victim’s attention from the silent encryption taking place. Initially dropped by an email spam campaign, the payload comes as a password protected zip archive, with the password made available in the body of the email to entice curious readers. In addition to the ESET removal instructions, the archive also contains a traditional ransom demand with instructions for purchasing and transferring Bitcoin.

Binance Crypto-Exchange Hacked

At least 7,000 Bitcoin were illicitly removed from the hot wallet of Binance, an international cryptocurrency exchange, in a single transaction. By compromising the personal API keys and bypassing two-factor authentication, the hackers were able to access the wallet and steal roughly $41 million worth of Bitcoin. The complete details of the breach are still unknown.

Global Malvertiser Sentenced in US

A man operating several fake companies distributing hundreds of millions of malicious ads across the globe has been arrested and is facing charges after his extradition to the U.S. For nearly five years, Mr. Ivanov and his co-conspirators created dozens of malvertising campaigns, usually starting a new one immediately after the previous one was flagged by a legitimate ad network. While this is not the only case of malvertising campaigns causing chaos on the web, it is one of the first to see actual indictments.

Robbinhood Ransomware Shuts Down Two US Cities

Both Baltimore City Hall and the city of Amarillo, Texas, were victims of a variant of Robbinhood ransomware this week. Following the attack, citizens of both cities will be seeing online bill payment options temporarily offline as they work to restore networks that were damaged or disconnected to stop the spread of the infection. This is the second cyber attack to hit both cities within the past year, with Potter County, Texas recovering from a similar attack just a couple weeks ago. Neither city has released more information on the ransom amount or when the attack began.

Freedom Mobile Exposes Payment Credentials

An unencrypted database containing millions of customer records for Freedom Mobile, a Canadian telecom provider, was discovered to be left freely available to the public. While the database was secured in less than a week, the time it was left accessible to criminals is cause for concern. The data contained full payment card information, including essentially everything a criminal would need to commit identity fraud against millions of people. Though Freedom Mobile claims the 15,000 were affected, it calls into question the practices used to store their sensitive data.

Cyber News Rundown: FBI Phishing Scam

Reading Time: ~ 2 min.

“FBI Director” Phishing Campaign

A new email phishing campaign has been making its way around the web that claims to be from “FBI Director Christopher Wray,” who would love to assist with a massive wire transfer to the victim’s bank account. Unfortunately for anyone hoping for a quick payday, the $10 million check from Bank of America won’t be arriving anytime soon, unless they are willing to enter more personal information and send it to a Special FBI agent using a Yahoo email address. While most phishing campaigns use scare tactics to scam victims, taking the opposite approach of offering a large payout seems less likely to get results.

Magecart Skimming Script Works on Dozens of Sites

Following the many Magecart attacks of recent years, a new payment skimming script has been found that allows attackers to compromise almost any online checkout page without the need to customize it for the specific site. The script currently works on 57 unique payment card gateways from around the world and begins injecting both the loader and the exfiltration script when the keyword “checkout” is searched for in the address bar.

Scammers Target Google Search Ads

Scammers are now turning towards Google Ads to post fake phone numbers posing to be customer support for popular websites such as eBay and Amazon. These phone scammers will often tell those who call that there is something wrong with their account and ask for a Google Play gift card code before they can help. The ads will look as if they are legitimate which causes confusion to those who call the phony numbers listed.  

Citycomp Data Dumped After Blackmail Attempt

Shortly after discovering that their systems had been breached, Citycomp announced they would not be paying a ransom for a large chunk of stolen client data. Unfortunately for Citycomp, the hackers decided to make the data publicly available after not receiving their requested $5,000. Amongst the stolen data is financial and personal information for dozens of companies for which Citycomp provides infrastructure services, though it may only be an initial dump and not the entire collection.

Email Scam Robs Catholic Church of Over $1.7 Million

The Saint Ambrose Catholic Parish in Ohio recently fell victim to email scammers who took nearly $2 million from the church currently undergoing a major renovation. The scammers targeted monthly transactions made between the church and the construction company by providing “updated” bank information for the payments and sending appropriate confirmations for each transfer. The church was only made aware of the breach after the construction company called to inquire about two months of missing payments.

High Value Cryptocurrency Stolen by Hackers

Reading Time: ~ 2 min.

Hackers Breach Private Keys to Steal Cryptocurrency

A possible coding error allowed hackers to compromise at least 732 unique, improperly secured private keys used in the Ethereum blockchain. By exploiting a vulnerability, hackers have successfully stolen 38,000 Ethereum coins so far, translating to over $54 million in stolen funds, though the current number is likely much higher. While uncommon, such attacks do show that the industry’s security and key-generation standards have plenty of room for improvement.

Prominent Malware Reverse Engineer Faces Jail Time

The malware researcher Marcus Hutchins, who successfully reversed and stopped the WannaCry ransomware attacks in 2017, is facing up to six years of jail time for prior malware creation and distribution. Hutchins’ charges all tie back to his involvement in the creation of Kronos, a widespread banking Trojan that’s caused significant damage around the world.

Data Exposed for Thousands of Rehab Patients

Personally identifiable data belonging to nearly 145,000 patients of a Pennsylvania rehab facility have been found in a publicly available database. After a Shodan search, researchers discovered the database that contained roughly 4.9 million unique documents showing information ranging from names and birthdays to specific medical services provided and billing records, all of which could be used to to steal the identity of these thousands of individuals.

Study Finds Password Security Still Lacking

After this year’s review of password security it may come as no surprise that the top five passwords still in use are simple and have remained at the top for some time. Using a list generated from past data breaches, researchers found the password “123456” was used over 23 million times, with similar variations rounding out the top five. Several popular names, sports teams, and bands like blink182 and Metallica are still in use for hundreds of thousands of accounts. While these passwords may be easy to remember, they are exceedingly simple to guess. Stronger passwords should include multiple words or numbers to increase the complexity.

Bodybuilding Site Breached through Phishing Campaign

The website bodybuilding.com has announced they were the victim of a data breach stemming from an email phishing campaign in July 2018 that could affect many of the site’s clients. Fortunately, the site doesn’t store full payment card data, and the data it does store is only stored at the customer’s request, leaving little data for hackers to actually use. The site also forced a password reset for all users issued a warning about suspicious emails coming from bodybuilding.com, noting they may be part of another phishing campaign.

Antivirus vs. VPN: Do You Need Both?

Reading Time: ~ 3 min.

Public concern about online privacy and security is rising, and not without reason. High-profile data breaches make headlines almost daily and tax season predictably increases instances of one of the most common types of identity theft, the fraudulent filings for tax returns known as tax-related identity theft

As a result, more than half of global internet users are more concerned about their safety than they were a year ago. Over 80% in that same survey, conducted annually by the Center for International Governance Innovation, believe cybercriminals are to blame for their unease.  

Individuals are right to wonder how much of their personally identifiable data (PII) has already leaked onto the dark web. Are their enough pieces of the puzzle to reconstruct their entire online identity?  

Questions like these are leading those with a healthy amount of concern to evaluate their options for enhancing their cybersecurity. And one of the most common questions Webroot receives concerns the use of antivirus vs. a VPN.  

Here we’ll explain what each does and why they work as compliments to each other. Essentially, antivirus solutions keep malware and other cyber threats at bay from your devices, while VPNs cloak your data by encrypting it on its journey to and from your device and the network it’s communicating with. One works at the device level and the other at the network level.  

Why You Need Device-Level Antivirus Security 

Antiviruses bear the primary responsibility for keeping your devices free from infection. By definition, malware is any software written for the purpose of doing damage. This is the category of threats attempting to undermine the antivirus (hopefully) installed on your PC, Mac, and yes, even smartphones like Apple and Android devices, too.  

In an ever-shifting threat landscape, cybercriminals are constantly tweaking their approached to getting your money and data. Banking Trojans designed specifically for lifting your financial details were among the most common examples we saw last year. Spyware known as keyloggers can surreptitiously surveil your keystrokes and use the data to steal passwords and PII. A new category of malware, known as cryptojackers, can even remotely hijack your computing power for its own purposes.  

But the right anti-malware tool guarding your devices can protect against these changing threats. This means that a single errant click or downloaded file doesn’t spell disaster. 

“The amazing thing about cloud-based antivirus solutions,” says Webroot threat analyst Tyler Moffit, “is that even if we’ve never seen a threat before, we can categorize it in real time based on the way it behaves. If it’s determined to be malicious on any single device, we can alert our entire network of users almost instantaneously. From detection to protection in only a few minutes.” 

Why You Need Network-Level VPN Security 

We’ve covered devices, but what about that invisible beam of data traveling between your computer and the network it’s speaking to? That’s where the network-level protection offered by a VPN comes into play.  

While convenient, public networks offering “free” WiFi can be a hotbed for criminal activity, precisely because they’re as easy for bad actors to access as they are for you and me. Packet sniffers, for instance, can be benign tools for helping network admins troubleshoot issues. In the wrong hands, however, they can easily be used to monitor network traffic on wireless networks. It’s also fairly easy, given the right technical abilities, for cybercriminals to compromise routers with man-in-the-middle attacks. Using this strategy, they’re able to commandeer routers for the purpose of seeing and copying all traffic traveling between a device and the network they now control.  

Even on home WiFi networks, where you might expect the protection of the internet service provider (ISP) you pay monthly, that same ISP may be snooping on your traffic with the intent to sell your data.  

With a VPN protecting your connection, though, data including instant messages, login information, social media, and the rest is encrypted. Even were a cybercriminal able to peek at your traffic, it would be unintelligible.  

“For things like checking account balances or paying bills online, an encrypted connection should be considered essential,” says Moffit. “Without a VPN, I wouldn’t even consider playing with such sensitive information on public networks.”  

How Webroot Can Help 

Comprehensive cybersecurity involves protecting both data and devices. Antivirus solutions to protect against known and unknown malware—like the kinds that can ruin a laptop, empty a bank account, or do a cybercriminals bidding from afar—are generally recognized as essential. But for complete protection, it’s best to pair your antivirus with a VPN—one that can shield your data from intrusions like ISP snooping, packet sniffers, and compromised routers.

Notice: What Happens on Public Computers, Stays on Public Computers

Reading Time: ~ 4 min.

These are the places your digital tracks can be dug up. With a little sleuthing.

Experts have warned for years of the risks of using public computers such as those found in libraries, hotels, and airline lounges. 

Many warnings focused on the potential for hackers to plant keystroke loggers, or intercept data as it flows across the internet. Indeed, in 2014, the National Cybersecurity and Communications Integration Center of the U.S. Secret Service issued an advisory for “owners, managers, and stakeholders in the hospitality industry” concerning data breaches. The text of the advisory claimed, “The attacks were not sophisticated, requiring little technical skill, and did not involve the exploit of vulnerabilities in browsers, operating systems or other software.” A 2014 announcement may seem to be an outdated reference, except that the recent Marriott data breach of over 300 million records was attributed to an attack in…wait for it…2014.)

But spyware and keyloggers aren’t the most common threat to the users of business center and other public computers. Forgetfulness, operating systems, applications, and temporary files are high up on the list. For several years I have searched public computers, mostly at hotels, to see what kinds of information people have left behind. It’s been an interesting passion project, to say the least.  

Uncovering a Very Public Digital Paper Trail

The first places I look are the documents, downloads, desktop, and pictures folders. The pictures folder typically yields the least interesting information, usually pictures of groups of drunken people, group gatherings at restaurants, weddings, or cats.

The desktop, document, and occasionally downloads folders are where most documents are inadvertently left behind. Some interesting samples I’ve discovered include a spreadsheet of faculty merit raises at a university in Texas, including the names of professors, their departments, their current salaries, and their projected raises. Another was the assignment of a chief officer to a ship belonging to one of the largest shipping companies in the world. It included the officer’s name, address, phone number, vessel name, date of assignment, and contact information.

I have come across corporate audits and strategic business plans. Recently, I discovered a document called “closing arguments” created by a district attorney. When possible, I contact the owners of the information to help them understand the risks of using public computers for sensitive work. I rarely hear back, however the DA did thank and assure me the document was a training example.

The biggest menace, however, has been the temporary files folders, which include auto-saved documents and spreadsheets, as well as attachments. It is in the Temporary Internet Files folder that I have uncovered complete emails, and even a webpage including a bank statement detailing a large balance, the account holder’s name, sources of income, and the names and addresses of places he had done business. Of all of the temporary files I have discovered, documents belonging to businesses’ employees have been the most unsettling. 

If you must, take precautions

There is some good news concerning the safety of public computers. Due to technology changes, I no longer find the contents of emails in the Temporary Internet Files folder. But we’re far from out of the woods. I have found my inbox cached, including pictures within emails and even a PDF that had not yet opened.

Although I could not open emails in the temoprary copy of my inbox shown above, subject lines and return email addresses may reveal more information than desired. 

Deleting temporary internet files is a good habit, but there are multiple locations that temporary files are stored. Documents edited on public computers remain of particular concern. Due to auto-save features, it’s possible to open a document on a thumb drive and leave auto-saved documents behind on the computer. Now in normal operating circumstances and with current operating systems and Office applications, this is not likely to happen. But errors like OS and application crashes will leave these copies behind. Microsoft Word and Excel will even proactively offer these auto-saved documents to the next user of these applications

The PDF file shown above was left behind when I read an email using my ISP’s webmail interface. 

Other than finding and deleting information left behind, my use of public computers is limited to reading online articles, checking the weather, and performing internet searches. What personal information you are willing to leave behind on a public computer depends on your risk tolerance. But it’s important to note that accessing corporate data on public computers could result in an inadvertent violation of company policies involving confidential data.

Although I still find public computers running Windows XP, there is a growing shift in the hospitality industry to use Kiosk applications. These provide limited functionality combined with locked-down security configurations. Access to the start menu is not possible and functionality is limited to desktop applications. Printing of boarding passes is a common allowed application. Reading web email is sometimes allowed, though I don’t recommend it because it requires entering a password. The risk of password compromise may be low, but the value of practicing quality security habits leads me to advise against it. If you must, consider changing your email password the next time you log onto a private computer.

If you happen to be using a public computer without a Kiosk interface, would you be so kind as to copy this blog, paste it into a Word document, and save it on the public computer to help inform the next user? They may end up paying it forward.

Cyber News Rundown: Phishing Attack on Global IT Outsourcer

Reading Time: ~ 2 min.

Major IT Outsourcer Suffers After Phishing Attack

Global IT services provider Wipro announced they are in the process of investigating a data possibly affecting some of their clients. These types of companies are popular for hackers because, by breaching a single IT service company, they gain access to a far larger pool of victims through compromised credentials belonging to client networks. It’s still unclear how long the hackers had access to the systems, but some reports claim the attack was ongoing for several months.

Age-Verification Hits UK Porn Viewers

The UK has passed a measure that will subject users to age-verifications before being allowed to enter a pornographic website, as part of their ongoing fight to make the UK safer online. This measure was originally introduced as a way to decrease ransomware infections and slow the stream of stolen credentials from paid accounts for higher-traffic sites. The new law has an 88% backing from UK parents and will go into full effect on July 15.

Data Breach Affects Navicent Patients

A recent Navicent Health announcement revealed the email systems of the health care services provider were compromised in July, 2018, possibly affecting over 275,000 patients. While the remainder of their internal systems were untouched, the email server did contain patient data, including social security numbers and billing information. Fortunately, Navicent responded to the breach quickly and began notifying the proper authorities, as well as their client base, in addition to providing identity monitoring services for those whose information was exposed.

Chrome for iOS Bug Redirects Users to Ads

A new bug, found only in the iOS version of Chrome, has exposed up to half a million users to unwanted advertising redirects, sometimes from legitimate websites. The bug works by allowing malicious code to be executed from within page advertisements, which can then overlay onto the device’s screen until clicked. The majority of this campaign’s victims are based in the US and were targeted over a four-day period in early April.

Microsoft Loses Subdomain for Live Tiles

A German researcher recently took control of a subdomain used by Microsoft to assist websites with correctly formatting RSS feeds into a usable XML format for Windows 8 and 10 Live Tiles. Because the subdomain wasn’t registered to Microsoft or their Azure cloud services, and any malicious actor could have compromised the domain, the researcher purchased it and alerted Microsoft of his findings.

Cyber News Rundown: Tax Extortion Ransomware Scams Corporations

Reading Time: ~ 2 min.

Tax Extortion Emails Bring Major Threats

A new email campaign has been spotted threatening ransomware and DDoS attacks over fake tax documents allegedly held by the attackers if a Bitcoin ransom isn’t paid. The campaign authors also threaten to send fake tax documents to the IRS through a poorly-worded ransom email that even provides Wikipedia excerpts for each threat put forward. Fortunately, as the campaign seems to be focused on corporations rather than individuals, no payments have been made to the attacker’s crypto coin wallet address.

Hotel Reservation Data Leaking Through Third-Party Services

As major data breaches continue to flood headlines, a recent study has revealed that nearly two of every three hotels exposes information about its guests to third-parties. Excerpts of the data show names, social security numbers, and payment card details that could give unauthorized users the ability to compromise identities or make changes to current reservations. Most of the exposed data involves comping through third-party services run on hotel websites offering customers additional packages.

Ransomware Conspirator Jailed in the UK

Police in the UK have officially charged and jailed a man for his part in the operation of a global ransomware campaign with ties to a Russian criminal organization. Charges range from fraud and blackmail to computer misuse relating to DDoS attacks and the Essex man is set to face at least six years. By masquerading as an advertising agent looking to purchase ad space on high-traffic sites, he was able to infect ad links with malware and other exploits to spread his campaign.

Firefox Begins Blocking Cryptomining Scripts

Even after the demise of CoinHive, cryptomining scripts are still being secretly deployed on thousands of websites without the knowledge of their owners and visitors. With the release of Firefox 67 beta, Mozilla is hoping to completely protect their users from malicious scripts that download and run cryptominers and other unwanted tracking software by using a blacklist created by Disconnect, a VPN developer with a reputation for privacy protection. Additionally, the new Firefox version will block fingerprinting scripts commonly used to invade a user’s browsing privacy.

MyCar App Uses Hardcoded Credentials

Thousands of cars were left vulnerable after a widely used vehicle telematics systems was found to be using hardcoded credentials in their mobile apps. Used in dozens of different car models to enable remote control functions, the hardcoded credentials leave these vehicles accessible to anyone with the app’s source code and the plaintext credentials within. Fortunately for users, the latest iOS and Android versions of the MyCar app have been updated to resolve this vulnerability.

Cyber News Rundown: Massive Data Breach at Georgia Tech

Reading Time: ~ 2 min.

Massive Data Breach at Georgia Tech

It was recently revealed that the personal information on over 1.3 million people was illicitly accessed by hackers who breached Georgia Tech systems in December of last year. The breach is the second of the year for the university, and was only discovered after IT staff noted performance issues on a widely used web application that interacts with a major database for both students and staff. 

Restaurant Firm Admits to Data Breach

Earl Enterprises, the parent firm of several popular restaurants around the country, recently announced they had fallen victim to a point-of-sale breach at multiple restaurant locations over the last 10 months. At least 100 restaurants, including all locations of the Italian chain Buca di Beppo, have begun working on restoring their systems and contacting affected customers. Nearly 2.1 million payment card accounts have been found in a dark web marketplace that were posted just a month before the company made its discovery.

Toyota Confirms Sales Data Breach

Personal information for over 3.1 million individuals may have been compromised before officials found signs of unauthorized activity on an internal network used in multiple sales subsidiaries of Toyota and Lexus. While the company’s dealerships continue to provide service and parts to customers, this specific breach comes only a month after another cyber attack that impacted Toyota dealerships in Australia, leaving many customers worried about the safety of their data.

GPS Watches Display PWNED! Message

Nearly a year after researchers contacted the watch maker Vidimensio about multiple vulnerabilities in their GPS watches, a new message has appeared on watch maps. The phrase “PWNED!” has been seen on at least 20 different watch models as a message alerting the company to their poor security infrastructure, as end-users are susceptible to being tracked through their watches. More alarmingly, many of the devices were found to have this vulnerability after Germany passed a law banning smart-watches for children that were capable of remote-listening after it was found they often ran on unpatched firmware.

Ransomware Strikes Albany, NY

The city of Albany, New York has been working to restore normal operations after a ransomware attack took down several key components of its systems. Aside from a few document-specific requests, however, the vast majority of the functionality was left undisturbed throughout the attack and recovery process. According to officials, all public safety services remained fully operational and had staff working around the clock to continue to provide assistance or direct individuals to a working facility.

Hijacked Email Reply Chains

Reading Time: ~ 4 min.

Although phishing has been around in various forms since the 1980s, our research shows it continues to evolve—and remains a major threat. These days, phishing tactics have gotten so sophisticated, it can be difficult to spot a scam—particularly in the case of hijacked email reply chains. Let’s look at a concrete example.

Imagine you’re a purchaser for a concrete supplier, and you get an email from a regular client about an order. In that email, you can see this client, Michael, has been exchanging messages with your colleague, Jill. The email addresses, corporate logos, and everything about the email chain look 100% legitimate. You’ve even met Michael in person, so you know he’s trustworthy.

In this case, the conversation details are convincing to you—because they’re real. Someone gained access to your colleague’s email and took over a legitimate conversation about purchases, then forwarded it to you with a malicious payload attached.

A message like this is very likely to get through any email filtering, and you’d probably open it, since it looks like it’s from a trusted sender.

Had you opened the file in this hypothetical scenario, you might have gotten infected with Emotet or another banking Trojan, such as Ursnif / Gozi.

This image is an example of a malicious word document asking you to “enable macros.” This is a common malware tactic that convinces a victim to disable their own security.

“Phishing attacks increased 36%, with the number of phishing sites growing 220 percent over the course of 2018.” – Webroot Inc. “2019 Webroot Threat Report.” (March 2019)

Ursnif / Gozi Campaigns

The difference between an ordinary phishing attack and a hijacked email chain really comes down to believability. The criminals behind these campaigns take their time breaking into email accounts, watching business conversations, negotiations, and transactions, then launching their attempts at plausible moments when the recipient’s guard is most likely to be down. Most commonly, these attacks have been attributed to Ursnif/Gozi campaigns. Webroot has seen quite a few cases of these hijacked emails with the same style of phishing text and nearly identical payloads. There are numerous reports online as well. 

In a malware campaign like this one, it really doesn’t matter whose account the malicious actors have broken into. If you receive an email from your project manager, a sales colleague, the finance department, a particular client, or anyone else that bears the markers of a legitimate, ongoing email conversation, the attack is highly likely to succeed.

Samples

Seen since last November: all email bodies had a long list of replies, but all had the following message.

This would suggest they are all samples that can be attributed to the same gang. Each had .zip files attached with convincing names related to the business at hand, which contained Microsoft® Word documents with filenames that started with “request”.

What You Can Do

Faced with such plausible attacks, it might seem impossible to stay safe. But there are a few tips that can keep you protected. First, never turn macros on, and never trust a document that asks you to turn macros on, especially if it’s a Microsoft® Office file that wants you to show hidden content. Macros are a very common attack vector.

Second, always make sure to keep your operating system up to date, especially Microsoft Office programs. 

Third, you likely already mistrust emails from people you don’t know. Now, it’s time to turn that suspicion onto trusted senders too. Attackers commonly try to spoof email addresses to look like those you’re familiar with, and may even gain control of an email account belonging to a person you know. Always err on the side of caution when it comes to emails asking you to download attachments. 

Fourth, it’s important to protect your own email account from being hijacked. Attackers can use techniques like alternate inboxing to send messages from your account without your knowledge. Be sure to secure your account with strong passwords, 2-factor authentication, or use a secure password manager. Encourage friends and colleagues to do the same.Finally, if you’re suspicious of an email, the best way to check its legitimacy is to pick up the phone. If you know the sender personally, ask them about the message in person or via phone. Or, if you receive a message from a company, look up their publicly listed phone number (do not use the number provided in the email) and call them.
