What it detects

This rule detects use of the cmd type command to copy a browser Login Data credential store into a temporary file. In SocGholish activity the stolen store was redirected into a rad prefixed tmp file for later DPAPI decryption. Copying the credential database is a precursor to bulk password theft from the endpoint.
