Cyber News Rundown: Healthcare Ransomware

The Cyber News Rundown brings you the latest happenings in cybersecurity news weekly. Who am I? I’m Connor Madsen, a Webroot Threat Research Analyst, and a guy with a passion for all things security. Any questions? Just ask.

Hospital Pays Ransom to Restore Systems, Despite Having Backups

In the first cyberattack of 2018 to hit a healthcare organization, an Indiana hospital’s entire network was taken offline. Despite having full backups on-hand, the hospital paid the $55,000 Bitcoin ransom right away. Officials stated they paid the ransom to get the systems back to normal as quickly as possible, since restoring everything from their backups could have taken weeks. Fortunately for patients, no data was stolen, and the staff could continue assisting new arrivals the old-fashioned way (that’s right: pen and paper) until system functionality was restored.

Audio Attacks Used for Damaging Hard Drives

A recent collaborative study performed by two universities proved that, within a reasonable proximity, an attacker could use acoustic signals to target a hard disk drive, leading to data corruption on the device. While many people could explain why this type of attack is possible, the study determined that the attacks required not only a specific frequency based on the hard drive in question, but also a precise distance from the drive and angle of sound projection to execute a successful attack.

New Android Platform Takes Spying to New Heights

A new Android spying platform has been discovered that puts all its predecessors to shame. By implementing several new features, such as location-based audio recording, compromising WhatsApp messages, and even allowing attackers to connect the device to malicious WiFi networks, this software platform gives attackers an all-new range of methods to target victims. The platform is based around five known exploits in the Android OS, and it uses them to gain administrative access to the device.

Latest Netflix Phish Asks for User Selfie

Within the last week, a new email phishing campaign has been spotted targeting Netflix users. The email informs users that a “hold” has been placed on their account pending further information. It requests users upload a photo of themselves with an ID card and prompts them to update their billing information, before redirecting them to the real Netflix login page.

RubyMiner Found on Older Linux and Windows Servers

A new cryptocurrency miner variant has been targeting outdated system servers that run both Linux and Windows. The variant, known as RubyMiner, identifies the unsecured servers using a web server tool, then gains access via a variety of exploits to install a modified Monero miner. RubyMiner deviates from similar miners in that it focuses on machines that have likely been forgotten about, and so remain on without being regularly patched.

Safe Deposit: How to Keep Your Cryptocurrency Secure

Safe Deposit: How to Keep Your Cryptocurrency Secure

“How to buy Bitcoin” dominated Google how-to searches in 2017, ranking third overall. With the hype surrounding cryptocurrency at an all-time high, now is a better time than ever to cover the essentials of keeping cryptocurrencies safe.

If you are just getting into the crypto space or you’ve known what ‘HODL’ means for a while now, there are some basics everyone should know about protecting their holdings.

Need-to-know: private keys

Let’s start with the basics. First and foremost, you should know the difference between your public and private wallet addresses (aka keys). A convenient analogy here is that most cryptocurrency wallets essentially operate like a postal box.

Each wallet has a unique public address that can be given out freely to anyone, much like you would give out your P.O. box address at a post office. This public address will only allow people to send coins to the wallet.

You also have a private address that unlocks your wallet and allows you to send coins out of it, similar to how your mail key allows you to unlock your P.O. box and withdraw your mail. This key is yours and yours only. Never share your private address with anyone.

Keeping up with your wallets’ private addresses is an exercise in personal responsibility. You don’t have a physical key to save you, and instead need to carefully store your private address (which is simply a long string of characters). Above all, storing private keys insecurely on your computer is an easy target for cybercriminals who use malware capable of sniffing out and copying your private keys.

If you choose to store private wallet addresses on your devices, never keep them in plain text format, and instead store them on a password-protected, encrypted drive. For maximum security, only print paper versions of your wallet and store multiple copies in secure places, such as a home safe or a bank safety deposit box. This technique is referred to as cold-storage, as your wallet is not stored on an internet-connected device. Hardware wallets, such as those made by Trezor or Ledger, are other options for secure storage of your crypto assets.

Risky business

Buying and storing coins on an exchange such as Coinbase is inherently risky, especially the storage part as you don’t have access to your wallets’ private addresses on an exchange. The convenience factor may be great—user-friendly apps, pretty charts, and a multitude of coins to explore—but on an exchange, you do not have access to your private wallet addresses.

To be fair, that’s part of the ease-of-use exchanges provide since you don’t have to worry about copy and pasting a private address every time you want to unlock a wallet to send from. But this also means that you are not in full control of your coins and if you were to violate any terms of the exchange (knowingly or unknowingly), they could ban your account and you would lose access to your coins. The same is true if the exchange was hacked. If they were improperly storing private keys, you could lose your coins forever.

Staying in full control of your wallet also has additional perks. In the case of a ‘hard fork’ or ‘airdrop’ to holders of a certain coin, you would be able to claim those. As it currently stands, most exchanges do not give you hard fork coins or airdrops, and instead keep those assets for themselves to increase profitability.

‘All your Bitcoin are belong to us’

Perhaps only one thing is certain in the crypto-world: hackers can and WILL try to steal your cryptocurrency.

While blockchain technology is considered an incredibly reliable, real-time database that’s proven resistant to attack and manipulation, wallet- and exchange-side security have shown numerous vulnerabilities over the years. Perhaps you’ve heard of the infamous Parity wallet hack in which an attacker exploited a wallet vulnerability to steal over 150,000 ETH (today that’s $165 million USD).

Just last week, a Google researcher discovered a bug in the popular Electrum wallet that would allow websites to steal the wallet’s contents, causing the Electrum team to quickly release a patch to fix the bug. Case in point—do your homework on any desktop, browser, or mobile wallets you plan to use. Don’t trust blindly.

Phish food

Beware of tried-and-true phishing attacks. Phishing attempts to steal private keys are abundant and targeted specifically toward unwitting investors chasing the crypto rush. Below is a phishing site that visually copies a legitimate site belonging to the wallet app Bread. Notice that the malicious URL (hxxp://breadtokenapp.com/sign.php) is just barely different than the legitimate URL (hxxps://token.breadapp.com/en/).

Dead giveaway. No website should ever ask for your private address. The same is true for exchanges as they manage wallets on their side and would never need your private keys either. The only circumstance where your private address needs to be inputted is to access a wallet. It’s a good idea to bookmark wallet sites such as the popular myetherwallet.com to make sure that you are always using the correct URL and not a phishing site.

It might seem obvious, but making sure your computer is free from malware is mission critical when dealing with cryptocurrencies. A trusted antivirus solution, secure password manager, and browser security can help protect you from would-be crypto thieves.

Update 2/8/2018:

Reports have surfaced recently that Ledger Nano S hardware wallets are susceptible to potential man-in-the-middle attacks.

The Ledger, while safe in offline storage, must still be connected to the internet to make transactions. Ledger has confirmed that their device is vulnerable to man-in-the-middle attacks (using malware that scans for the recipient’s address and changes it to the hacker’s own address). This reiterates the importance of always double-checking the wallet address that you intend to send to, as well as ensuring your computer is free from malware.

Exploitable Backdoor Found in Western Digital NAS Drives

Western Digital has recently released numerous patches for the vulnerabilities that were found and reported to the vendor nearly six months ago. The prominent issue revolved around a hard-coded administrative backdoor that could allow attackers to remotely execute files on the drives. Unfortunately for Western Digital, this series of vulnerabilities comes not long after the same generation of drives were found with 85 different exploits (and the company waited to push out patches until after the exploits had come to public attention.)

Welsh Restaurant Closes After Cyberattack

In the past month, the owner of a Welsh restaurant has been struggling to keep the doors open on the Seafood Shack following a cyberattack that completely cleared out the restaurant’s reservation system in the weeks before to Christmas. The restaurant is currently closed after nearly a month without patronage. The systems weren’t being monitored manually, so every diner’s booked tables were left empty. In addition to the cyberattack, the restaurant also faced licensing issues after a supervisor left their employ.

Winter Olympics Organizers Targeted by Phishing Attacks

Officials working on the Pyeongchang Winter Olympics have been under a constant stream of phishing attacks disguised as Microsoft® Word documents from a South Korean intelligence agency. The documents work like normal ones, but request that the user enable macros to launch a PowerShell script. Another version of the malware even bypassed the need for user permission, and instead waited for the user to click the .docx icon to change the language to Korean before launching the same PowerShell script.

Older Zero-Day Exploit Released on New Year’s Eve

In an unusual finish for 2017, one researcher chose to release a 15-year-old macOS® exploit into the wild. The exploit requires local access to the device, but, once active, would give any attacker full root access to the machine after the user logged out of their session. Even though all Mac® operating systems are susceptible to this vulnerability, it’s only a matter of time until Apple steps in and corrects the issue and give their massive client-base some piece of mind.

Opera Browser Implements Anti-Cryptojacking Functions

With the recent emergence of cryptojacking (i.e., exploiting an unwitting user’s CPU to mine cryptocurrency while they visit a hijacked website), Opera has taken a stand and implemented crypto-mining protection called “NoCoin” in their current ad blocking filter. NoCoin works by detecting any mining activity on a visited website and stops the mining, freeing up the system’s processor for actual user-initiated applications.

Researchers Find Major Security Flaws in Modern Processors

Newly discovered bugs, Meltdown and Spectre, exploit critical flaws in the architecture of many modern processors to leak system memory and view information that should remain hidden at the application level. This vulnerability would allow hackers to steal secret information, such as stored passwords, although there are no known exploits currently in use. Operating system makers such as Microsoft, Apple, and Linux scrambled on Wednesday to release security updates to protect users. Experts speculate these flaws will impact the security industry for many years to come.

‘Trackmageddon’ Bugs Leave GPS Data Open to Hackers

Two security researches have uncovered several vulnerabilities that affect GPS tracking services, including those used in child and pet trackers. These vulnerabilities range from weak passwords and unsecured folders to unprotected API endpoints, according a report issued by the research team. Hackers could potentially exploit these flaws to collect private data from these location-tracking services.

Clothing Retailer Finds Malware on PoS Devices

The LA-based fashion retailer Forever 21 revealed that a recent data breach resulted in the theft of customer credit card information. Following an investigation, Forever 21 disclosed that point-of-sale devices were infected with malware following a lapse in data encryption. While it’s still unclear how many stores and customers have been affected, the retailer advises all customers to keep a close eye on their financial statements and credit reports for suspicious activity.

Cancer Care Provider Reaches Settlement over HIPAA Violations

21st Century Oncology has reached a $2.3 million settlement agreement with the US Department of Health and Human Services following a data breach that leaked patient records and Social Security numbers of some 2 million patients. According to a press release from HHS, the breach was uncovered after an FBI informant was able to illegally obtain the company’s private patient files from a third party.

Android Malware Variant Steals Uber Data

Fakeapp malware found on Android devices spoofs Uber app to appear legitimate to users. This new malware tricks users into entering their account credentials by imitating the Uber app’s user interface. This attack underscores the need for caution when downloading apps, even from the Google Play store, as well as using a trusted a mobile security solution.

WordPress Backdoor Found on Over 300,000 Machines

Recently, researchers found a WordPress plugin containing a backdoor that could allow criminals to easily access any device on which the plugin is installed (at least 300,000 machines, in this case). Even more worrisome: the backdoor wasn’t discovered until the plugin’s author was cited in a copyright claim over the use of the “WordPress” brand. The WordPress security team quickly updated the plugin and began force-installing it on all compromised sites.

Billions of Credentials Found on Dark Web

In a recent data dump on the Dark Web, researchers have discovered a trove of credentials for at least 1.4 billion users, all of which was stored in plain text and was easily searchable. While some of the data had already been released in a previous data dump, it appears most of the credentials were new and verified as authentic. Unsurprisingly, the dump has also revealed that the majority of users still have incredibly weak passwords. The most common is still “123456”.

Data on Millions of Americans Left Unattended Online

Earlier this year, researchers discovered yet another AWS S3 database left misconfigured and freely available to anyone with AWS credentials. The database belongs to Alteryx, a marketing analytics company, and revealed financial information for at least 123 million Americans. Although, fortunately, the database didn’t contain full names or social security numbers, the 248 available data fields could easily be used to identify specific individuals.

Thousands of Lexmark Printers Left Unsecured

Over 1,000 internet-connected Lexmark printers have been found to have zero security measures; most lacked even a simple password. Additionally, many of these printers have been traced back to prominent companies and even government organizations. And while sensitive information isn’t directly available, hackers could cause major disruptions to the devices’ functions, and could even install malware to remotely capture any print jobs that might contain valuable data.

Android Mobile Game Silently Leaking Data

A relatively new mobile game on the Google Play Store appears to leak sensitive data from both the device’s user and the device itself almost constantly. Dune!, the app, has been downloaded at least 5 million times, and has been known to connect to up to 32 different servers to silently transmit stolen data and access a device’s geolocation data. Along with its true functionality, Dune! carries at least 11 known vulnerabilities that make it prone to additional attacks and further data leakage.

 

3 Tips for Securing Your Home WiFi Networks

3 Tips for Securing Your Home WiFi Networks

Once your home WiFi network is up and running and your family’s devices are connected, it’s normal to turn a blind eye to your router. After all, it’s mostly out of sight and out of mind. Unfortunately, that small, seemingly harmless box isn’t as secure as you may think.

Your router is your gateway to the internet. Once it’s compromised, cybercriminals may be able to view your browser history, gain access to your login information, redirect your searches to malicious pages, and potentially even take over your computer to make it part of a botnet.

Attacks like these are becoming all too common. Last year, we saw a prime example when hackers gained access to routers from various manufacturers and infected consumers’ devices with malicious advertising (also known as malvertising).

In a more recent attack, hackers entered WordPress sites through their owners’ unsecured home routers. After hacking the router, the attackers successfully guessed the password for the WordPress accounts and took complete control of the sites. As security experts noted, this particular hack was made even worse by the fact that most users have little to no understanding of how to secure their home router.

Beef up your home Wifi network security

Here are a few precautionary steps you can take to help deter cybercriminals from infiltrating your home WiFi network:

  • Change the default username and password on your route. (Remember to update your WiFi password frequently!)
  • Configure your router’s settings to use strong network encryption (WPA2 is preferred).
  • Disable your router’s SSID broadcast so it isn’t visible to others.

 

Do you live in one of the most-hacked states?

 

Additionally, Webroot Chief Information Security Officer (CISO) Gary Hayslip recommends enabling a personal firewall.

“Hackers search the internet by using certain tools to send out pings (calls) to random computers and wait for responses,” he said. “Your firewall, if configured correctly, would prevent your computer from answering these calls. Use your personal firewall. The main point to remember is that firewalls act as protective barriers between computers and the internet, it is recommended you install them on your computers, laptops, tablets, and smart devices if available.”

NC County Crippled by Ransomware Attack

Recently, a county in North Carolina was the target of a substantial ransomware attack that took many of their official systems offline, and may have affected over a million residents. Nearly 10% of the county’s servers were forced offline with a ransom demand of $23,000. County officials have stated they will not be paying, as there are no guarantees with ransomware, and will work to recover systems as quickly as possible.

Starbucks In-Store Wi-Fi Used to Mine Cryptocurrency

In the past week, a researcher discovered that the Argentinian rewards site for Starbucks was silently running a coin-mining script to generate Monero coins. Even more worrisome: more than 5,000 unique sites have been identified which are also be running some form of CoinHive code to mine cryptocurrency by sapping unsuspecting visitor’s CPU power. Fortunately for fans of free WiFi, Starbucks was quick to contact their internet service provider and resolve the issue.

Brand New HP Laptops Come with a Nasty Surprise

Keylogging software was recently discovered on over 400 models of HP laptops—preinstalled in their keyboard drivers. Even though the keylogger is disabled by default, it wouldn’t be difficult for anyone with access to the device to compromise its security by enabling it to record users’ keystrokes. Luckily for HP users, the company promptly issued a patch that removed the keylogging software from affected devices.

Spider Ransomware Focused on Balkans

Over the last few days, researchers have been monitoring a new ransomware variant called “Spider” as it works its way across the Balkan region of Europe. Surprisingly, this variant gives victims a mere 96 hours to pay the ransom. In addition to the tight deadline, the ransomware makes several attempts to ease the payment process for victims by providing an “educational” video tutorial and giving the user steady reassurance on how simple it is. As with many other ransomware variants, Spider spreads through malicious Microsoft® Office documents that request users to enable macros.

Mirai Botnet Creators Federally Charged in US

The creators of the original Mirai botnet have been federally charged for its initial creation and use as a DDoS-for-hire service. At its peak, Mirai affected over 300,000 individual IoT devices. Apparently, after the major DDoS attack earlier this year against DNS provider Dyn, one of the creators released the source code in the hope that others might use it, thereby obscuring the trail leading back to him.
