Linux Under Siege: Gelsemium’s New Backdoor Hits Harder Than a Kernel Panic!
Linux malware is on the rise, with new backdoors like Wolfsbane and Firewood making headlines. Gelsemium, known for targeting Windows systems, has now adapted to Linux. As organizations increasingly adopt Linux, adversaries are crafting cross-platform malware to maximize their reach, proving that even penguins aren’t safe from cyber shenanigans.
Hot Take:
Looks like the cyber bad guys have discovered that Linux is the new Windows. Who knew penguins had such juicy secrets worth stealing? And here we thought Linux was just for hipster developers and servers nobody looked at twice.
Key Points:
- Chinese APT “Gelsemium” has adapted its malware to target Linux systems with new backdoors: Wolfsbane and Firewood.
- The Linux malware landscape is rapidly expanding as organizations increasingly adopt Linux for server needs.
- Wolfsbane is a Linux adaptation of the Windows backdoor Gelsevirine, using a modified rootkit.
- Firewood, potentially linked to Gelsemium, is a kernel-level rootkit evolving from the longstanding “Project Wood.”
- Rising Linux cyber threats are attributed to increased Linux use in enterprises and improved security on Windows systems.
