What it detects

This rule detects a process executing from /var/tmp/systemd-logind, a Linux cryptominer masquerading as the legitimate systemd-logind daemon which normally runs from /usr/lib/systemd. It was observed in a Huntress-investigated intrusion where a Monero miner beaconed to a mining pool over port 443. Execution of a trusted daemon name from a world-writable temporary directory indicates resource-hijacking malware attempting to evade casual process review.
