Malware researchers from ESET have discovered a new Linux malware dubbed Linux/Shishiga targeting systems in the wild.

The Linux/Shishiga malware uses four different protocols (SSH, Telnet, HTTP and BitTorrent) implements a modular architecture by using Lua scripts.

 

“Among all the Linux samples that we receive every day, we noticed one sample detected only by Dr.Web – their detection name was Linux.LuaBot. We deemed this to be suspicious as our detection rates for the Luabot family have generally been high. Upon analysis, it turned out that this was, indeed, a bot written in Lua, but it represents a new family, and is not related to previously seen Luabot malware. Thus, we’ve given it a new name: Linux/Shishiga. It uses 4 different protocols (SSH – Telnet – HTTP – BitTorrent) and Lua scripts for modularity.” reads the analysis published by security firm ESET.
