The final days of May have been quite tumultuous in the context of internet security. Online attacks continue to occur at an alarmingly high frequency here in the United States and abroad. Below, we shine the spotlight on some of the week's most important breaches, attacks, and other digital offensives that made living and working even more challenging amid a looming recession and an ongoing conflict abroad.
PDFs Used for Keylogger
Digital thieves are now using PDF files for keyloggers. Keyloggers infect target computing devices, specifically with a snake keylogger that employs an email campaign. The keylogger capitalizes on a Microsoft Office RCE bug. As long as the target clicks the compromised PDF file attached to the email, the wheels are in motion for the keylogger to victimize yet another computer user. If you have not updated your digital security protections in recent months to fortify your computer's defenses, now is the time to do so.
Bug Used to Steal PayPal Funds
A bug is allowing digital criminals to steal money from targeted PayPal accounts. The parties behind the attack create a seemingly harmless link that actually processes PayPal transactions when clicked. The attack is complex to the point that it displays a superimposed HTML component, making it appear as though certain links and icons are being clicked when they are not. Instead, the target is sent to another site where their information is gathered so funds can be removed from the account.
Xor malware, typically described as a variety that uses shell brute force, is on the rise. The malware is zeroing in on Linux operating systems. Microsoft recently revealed the malware has increased by more than 250% in activity. The Xor malware is a Trojan that attacks computers that run on Linux, using distributed denial of service infiltrations. Though the malware has been around for more than eight years, it is still evolving. The saving grace is the fact that Microsoft has succeeded in halting Xor malware attacks.
The Fronton botnet is capable of tracking a target's internet activity and other computer actions. The botnet pilfers information, flexes its influence to disinform social media uses, and generally manipulates the public for nefarious purposes. The botnet attacks through DDoS, tracks social media activities, monitors trends, and even goes as far as using online propaganda to shape opinions. The Fronton botnet has only been around since the spring of 2020, yet it is considered to be a major source of disinformation as we approach the midterm elections.
Yashma Ransomware Found in the Wild
A new ransomware variant, referred to as the Yashma variant, has been identified in the wild. This customizable ransomware is available for purchase on the black market, meaning everyone is a potential target of those willing to pay the price necessary to launch a ransomware attack. The Chaos builder has been in the wild for about a year though the latest incarnation is its sixth. Each of the ransomware's upgrades has made it that much more efficient and destructive
