ESXi Host Logs Deleted with rm

Detects a shell `rm` of a path under `/var/log` or of a `*.log` name. Those files hold shell commands, authentication, and hostd activity. Removing them takes away the record of what changed on the host.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Detections can measure how the public catalogue is used — which detections people look for, and which pages bring them here. It sets a cookie that recognises this browser for 180 days. It is never linked to an account and never follows you to other sites. Privacy notice
