Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected Xmrig cryptocurrency miner
Executes the "crontab" command typically for achieving persistence
Executes the "iptables" command to insert, remove and/or manipulate rules
Found strings related to Crypto-Mining
Sample is packed with UPX
Sample reads /proc/mounts (often used for finding a writable filesystem)
Sample tries to persist itself using cron
Tries to load the MSR kernel module used for reading/writing to CPUs model specific register
Writes to CPU model specific registers (MSR) (e.g. miners improve performance by disabling HW prefetcher)
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 "iptables" command used for managing IP filtering and manipulation
Executes the "modprobe" command used for loading kernel modules
Reads CPU information from /proc indicative of miner or evasive malware
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
Sample tries to kill a process (SIGKILL)
Uses the "uname" system call to query kernel version information (possible evasion)
Yara signature match
