What it detects

This rule detects restic backing up local data to a rest remote repository, an exfiltration technique that abuses a legitimate backup tool to move victim files to attacker-controlled storage. This was catalogued among data-exfiltration LOLBIN binaries. Backing up internal data to an external repository indicates active theft ahead of extortion.
