Detection

Score: 48
Range: 0 - 100
Whitelisted: false

Signatures

Multi AV Scanner detection for submitted file
Contains symbols related to standard C library sleeps (sometimes used to evade sandboxing)
Detected TCP or UDP traffic on non-standard ports
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)
