Detection

Score: 52
Range: 0 - 100
Whitelisted: false

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
Sample has stripped symbol table
Sample listens on a socket
Tries to resolve domain names, but no domain seems valid (expired dropper behavior)
Uses the "uname" system call to query kernel version information (possible evasion)
