Detection

Score: 56
Range: 0 - 100
Whitelisted: false

Signatures

Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
ELF contains segments with high entropy indicating compressed/encrypted content
Sample contains only a LOAD segment without any section mappings
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)
