Detection

Score: 60
Range: 0 - 100
Whitelisted: false

Signatures

Connects to many ports of the same IP (likely port scanning)
Opens /sys/class/net/* files useful for querying network interface information
Performs DNS TXT record lookups
Sample deletes itself
Sample scans a subnet
Detected TCP or UDP traffic on non-standard ports
Sample has stripped symbol table
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)
