New Linux Malware Mines Crypto While Remaining Undetectable

Two threat analysts recently stumbled upon new Linux malware that keeps its cryptocurrency mining operations hidden.

On Sept. 16, Augusto Remillano II and Jakub Urbanec revealed in a post on Trend Micro, a security intelligence blog, that they found new Linux malware. According to the analysts, this malware is particularly notable because of the way it loads malicious kernel modules to hide its cryptocurrency mining operations.

Malware provides hackers full access to infected machine

The analysts revealed that Skidmap masks its cryptocurrency mining by utilizing a rootkit, which is a program that installs and executes code on a system without end user consent or knowledge. This makes its malware components undetectable by the infected system’s monitoring tools.


Besides running a cryptojacking campaign on the infected machine, the malware reportedly gives attackers “unfettered access” to the affected system. The analysts add:

“Skidmap also sets up a way to gain backdoor access to the machine, and also replaces the system’s pam_unix.so file with its own malicious version. This malicious file accepts a specific password for any users, thus allowing the attackers to log in as any user in the machine.”
