Fybis showed its first signs in November 2014.
This group is a fairly well known cyber espionage group believed to have ties to Russia.
Fysbis is a modular Linux trojan / backdoor that implements plug-in and controller modules as distinct classes.
This malware includes both 32-bit and 64-bit versions of Executable and Linking Format (ELF) binaries.
One can see why APT 28 values its versatility and selected to add it to its attack resource.
Linux security in general is still a maturing area, especially in regards to malware.
