What it detects

This rule detects execution of the rshijack tool used to inject data into established TCP sessions. Wiz Research observed rshijack abused inside a shared Replicate environment to hijack traffic to a central Redis instance, so its use strongly indicates adversary in the middle or lateral movement activity.
