Syslogk Linux Rootkit Detection: Novel Malware Used in the Wild

Syslogk Linux Rootkit

New kernel rootkit named Syslogk is getting traction, terrorizing the Linux OS users.

The novel rootkit malware is believed to be based on another Linux rootkit dubbed Adore-Ng – a loadable module used to infect the Linux OS kernel. While Syslogk’s operators are currently invested in its development, enhancing the functionality of the new rootkit, the number of affected devices already keeps mounting.

Syslogk Linux Rootkit Description

There has been a number of attacks recently affecting Linux systems. Today, Linux OS users are facing the emergence and active development of a novel highly-evasive rootkit malware dubbed Syslogk. The malware installs as kernel modules in the Linux OS. Adversaries utilize Syslogk to conceal their traces within the infected system, remain stealthy, and evade manual inspection. Besides, the new malware has the functionality to remotely start or stop payloads, widely used to fetch a C-based compiled backdoor trojan dubbed Rekoobe, activated by “magic packets” orchestrated by adversaries.

The first comprehensive analysis of the Syslogk Linux rootkit was released by security researchers from Avast. The experts pointed out that Rekoobe activation may result in such malicious actions as data theft, file manipulation, and account hijacking.
