Signatures

Multi AV Scanner detection for submitted file
Connects to many ports of the same IP (likely port scanning)
Detected TCP or UDP traffic on non-standard ports
Executes the "rm" command used to delete files or directories
Reads CPU information from /proc indicative of miner or evasive malware
Reads system information from the proc file system
Sample has stripped symbol table
Sample listens on a socket
Uses the "uname" system call to query kernel version information (possible evasion)
