Signatures

Antivirus / Scanner detection for submitted sample

Malicious sample detected (through community Yara rule)

Multi AV Scanner detection for submitted file

Yara detected Prometei

Drops files in suspicious directories

Executes the "crontab" command typically for achieving persistence

Sample is packed with UPX

Sample tries to persist itself using cron

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

Reads CPU information from /sys indicative of miner or evasive malware

Sample contains only a LOAD segment without any section mappings

Sample tries to set the executable flag

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)

Yara signature match
