Signatures

Sample is packed with UPX
ELF contains segments with high entropy indicating compressed/encrypted content
Executes commands using a shell command-line interpreter
Executes the "grep" command used to find patterns in files or piped streams
Reads CPU information from /sys indicative of miner or evasive malware
Reads system information from the proc file system
Reads the 'hosts' file potentially containing internal network hosts
Sample contains only a LOAD segment without any section mappings
Sample listens on a socket
Uses the "uname" system call to query kernel version information (possible evasion)
