What it detects
This rule detects wget downloading content to standard output and piping it directly into a shell, a download and execute technique used by Kinsing and H2Miner cryptomining loaders to run remote scripts without touching disk. This lets attackers execute staged payloads from their infrastructure while minimizing forensic artifacts.
Reporting behind it
Detection content is published as a reviewed draft. Tune thresholds and exclusions against your own telemetry before enabling this rule for alerting.
