Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Suricata IDS alerts for network traffic
Yara detected Prometei
Drops files in suspicious directories
Found Tor onion address
Machine Learning detection for dropped file
Machine Learning detection for sample
Sample deletes itself
Sample is packed with UPX
Creates hidden files and/or directories
ELF contains segments with high entropy indicating compressed/encrypted content
Enumerates processes within the "proc" file system
Executes commands using a shell command-line interpreter
Executes the "pgrep" command search for and/or send signals to processes
Executes the "systemctl" command used for controlling the systemd system and service manager
HTTP GET or POST without a user agent
Reads CPU information from /sys indicative of miner or evasive malware
Reads system information from the proc file system
Sample contains only a LOAD segment without any section mappings
Sample listens on a socket
Sample tries to set the executable flag
Suricata IDS alerts with low severity for network traffic
Uses the "uname" system call to query kernel version information (possible evasion)
Writes ELF files to disk
Yara signature match
