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
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)
