AT&T Alien Labs has discovered a new malware targeting endpoints and IoT devices that are running Linux operating systems. Shikitega is delivered in a multistage infection chain where each module responds to a part of the payload and downloads and executes the next one. An attacker can gain full control of the system, in addition to the cryptocurrency miner that will be executed and set to persist.

In our previous article Yet another bug into Netfilter, I presented a vulnerability found within the netfilter subsystem of the Linux kernel. During my investigation, I found a weird comparison that does not fully protect a copy within a buffer. It led to a heap buffer overflow that was exploited to obtain root privileges on Ubuntu 22.04.
