Detection

Score: 56
Range: 0 - 100
Whitelisted: false

Signatures

Multi AV Scanner detection for submitted file
Contains symbols with names commonly found in malware
Connects to many ports of the same IP (likely port scanning)
Uses the "uname" system call to query kernel version information (possible evasion)
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Detected TCP or UDP traffic on non-standard ports
Sample listens on a socket
