Signatures
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Sample is packed with UPX
Detected TCP or UDP traffic on non-standard ports
ELF contains segments with high entropy indicating compressed/encrypted content
Sample contains only a LOAD segment without any section mappings
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)
Yara signature match
