What it detects

This rule detects a process executing from the per-service private temporary path /tmp/systemd-private- which Wiz observed attackers abusing to hide XMRig Sliver and Mirai payloads after exploiting the Aviatrix Controller RCE CVE-2024-50603. This is important because binaries running out of a systemd private tmp namespace are almost always malware staged to evade detection so execution from this location signals post-exploitation deployment of miners and implants.
