This detection rule identifies potential credential dumping attempts through the creation of symbolic links to shadow copies. By analyzing data from the Endpoint.Processes data model in Splunk, it specifically looks for processes running commands that reference "mklink" in conjunction with "HarddiskVolumeShadowCopy". This method is significant as it may indicate that an attacker is manipulating or deleting shadow copies to interfere with backup recovery, which can lead to significant data loss or compromise. The rule advises analysts to scrutinize the process details, including the user, parent process, and associated artifacts to trace the attack origins more clearly.
