Signatures

ELF contains segments with high entropy indicating compressed/encrypted content
Executes the "rm" command used to delete files or directories
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)
