Round Up of Major Breaches and Scams

Years-long campaign targets hackers through trojanized hacking tools

Vietnam based threat group has been hacking other hackers through njRAT infected hacking tools. Instead of directly hacking systems, spreading trojanized hacking tools gives them complete access to a much larger pool of hacked data. These trojanized tools have been around for years, some of which are site scrapers, exploit scanners, SQL injection tools, credential verification tools, and even trojanized versions of the Chrome browser.

Bogus HIV test results are the latest lures used by cybercrooks

Even as COVID-19 related phishing attacks flourish, attackers have started distributing malware in the guise of emails that contain HIV test results. Since there is still a lot of misinformation and fear regarding HIV, victims tend to fall for the trap. A Russian hacking group purportedly sent 200 such phishing emails to employees of a large North American pharmaceutical and insurance companies. This infects the companies’ systems with Koadic RAT, which allows attackers to track keystrokes and execute code on the affected systems.

Round Up of Major Malware and Ransomware Incidents

How poor IoT security is allowing this 12-year-old malware to make a comeback

Poor security of Internet of Things (IoT) devices helps sustain the antiquated malware Conficker. The malware, which was first spotted in 2008, primarily exploits flaws in Windows XP and older versions. The recent resurgence has been attributed to connected medical devices which still run on outdated/ unsupported versions of Windows. Recently, a hospital detected unusual activity in its mammography machine and found that several of their devices had been infected by Conficker. The hospital took their systems offline and installed patches.

Paradise Ransomware distributed via uncommon spam attachment

Attackers have started to send Excel Web Query attachments in phishing campaigns to download and install the Paradise Ransomware on unsuspecting victims. Paradise Ransomware is fairly old with activity going as far back as September 2017 when it was first reported by a victim in the BleepingComputer forums. Since then, there has been a steady trickle of victims from this ransomware as can be seen from the submissions to the ransomware identification site ID-Ransomware.
