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.

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.
