<p>Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery. This may deny access to available backups and recovery options.</p><p>Operating systems may contain features that can help fix corrupted systems, such as a backup catalog, volume shadow copies, and automatic repair features. Adversaries may disable or delete system recovery features to augment the effects of Data Destruction and Data Encrypted for Impact. Furthermore, adversaries may disable recovery notifications, then corrupt backups.</p><p>A number of native Windows utilities have been used by adversaries to disable or delete system recovery features:</p>
- <li><code>vssadmin.exe</code> can be used to delete all volume shadow copies on a system - <code>vssadmin.exe delete shadows /all /quiet</code></li><li>Windows Management Instrumentation can be used to delete volume shadow copies - <code>wmic shadowcopy delete</code></li><li><code>wbadmin.exe</code> can be used to delete the Windows Backup Catalog - <code>wbadmin.exe delete catalog -quiet</code></li><li><code>bcdedit.exe</code> can be used to disable automatic Windows recovery features by modifying boot configuration data - <code>bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures & bcdedit /set {default} recoveryenabled no</code></li><li><code>REAgentC.exe</code> can be used to disable Windows Recovery Environment (WinRE) repair/recovery options of an infected system</li><li><code>diskshadow.exe</code> can be used to delete all volume shadow copies on a system - <code>diskshadow delete shadows all</code></li>
vim-cmd vmsvc/snapshot.removeall).</p><p>Adversaries may also delete “online” backups that are connected to their network – whether via network storage media or through folders that sync to cloud services. In cloud environments, adversaries may disable versioning and backup policies and delete snapshots, database backups, machine images, and prior versions of objects designed to be used in disaster recovery scenarios.</p>KEV CVEs mapped to this technique · CTID Mappings Explorer

Detects the image load of vss_ps.dll by uncommon executables. This DLL is used by the Volume Shadow Copy Service (VSS) to manage shadow copies of files and volumes.
It is often abused by attackers to delete or manipulate shadow copies, which can hinder forensic investigations and data recovery efforts.
The fact that it is loaded by processes that are not typically associated with VSS operations can indicate suspicious activity.
