Signatures

Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected Xmrig cryptocurrency miner
Contains symbols with names commonly found in malware
Detected Stratum mining protocol
Found strings related to Crypto-Mining
Machine Learning detection for sample
Sample reads /proc/mounts (often used for finding a writable filesystem)
Stdout / stderr contain strings indicative of a mining client
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)
Creates hidden files and/or directories
Executes commands using a shell command-line interpreter
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 has stripped symbol table
Suricata IDS alerts with low severity for network traffic
Uses the "uname" system call to query kernel version information (possible evasion)
Yara signature match
