Experts have recently discovered an upgraded version of the BPFDoor malware for Linux (opens in new tab) , that’s seemingly harder to spot - and aAs a result, no antivirus programs are still flagging the executable as malicious. . Cybersecurity researchers from Deep Instinct noted that BPFDoor, which was first discovered in 2022, has been active since at least 2017. The tool got its name from the (ab)use of the Berkley Packet Filter (BPF), which it uses to get instructions and bypass any firewalls. Its design allows the threat actors to remain undetected on a compromised Linux system for longer periods of time, it was said. BPFDoor’s key feature is allowing threat actors to see all network traffic and find vulnerabilities, as well as sending out remote code through (now) unfiltered and unblocked channels. . Researchers disclose an enhanced version of the BPFDoor malware targeting Linux, recognized for its ability to avoid antivirus measures and infiltrate devices..

For the past four years the SANS Institute has partnered with the FBI's National Infrastructure Protection Center to compile and publish its list of the most commonly exploited IT security vulnerabilities. This list is regularly updated and revised. Earlier, I examined the latest Windows threats from the list. Now I'll cover the top 10 Linux/Unix threats. It's important to recall that, unlike the ever-growing list of new exploits found in operating systems and applications, the SANS-FBI list prioritizes them according to the actual number of attacks seen by the organizations surveyed.

"The Anna Kournikova e-mail worm that whacked networks this week was not the work of a skilled cracker. It was created using one of the many virus-generating kits that are easily available on the Internet. The kits, which have names like Satanic Brain Virus Tools 1.0, Instant Virus Production Kit, and Ye Olde Funky Virus Generator, make writing a virus a straightforward and uncomplicated task. If you can install a program on a computer, you can also -- using one of these kits -- write and release a virus just like the authors of Cartman, Poppy and Kenny did.
