Malware targeting Linux users may not be as widespread as the strains targeting the Windows ecosystem, but Linux malware is becoming just as complex and multi-functional as time passes by.
The latest example of this trend is a new trojan discovered this month by Russian antivirus maker Dr.Web. This new malware strain doesn't have a distinctive name, yet, being only tracked under its generic detection name of Linux.BtcMine.174.
The trojan itself is a giant shell script of over 1,000 lines of code. This script is the first file executed on an infected Linux system. The first thing this script does is to find a folder on disk to which it has write permissions so it can copy itself and later use to download other modules.
Once the trojan has a foothold on the system it uses one of two privilege escalation exploits CVE-2016-5195 (also known as Dirty COW) and CVE-2013-2094 to get root permissions and have full access to the OS.
