Препятствование восстановлению системы

Adversaries may delete or remove built-in operating system data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.(Citation: Talos Olympic Destroyer 2018)(Citation: FireEye WannaCry 2017) This may deny access to available backups and recovery options. 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.(Citation: Talos Olympic Destroyer 2018)(Citation: FireEye WannaCry 2017) A number of native Windows utilities have been used by adversaries to disable or delete system recovery features: * vssadmin.exe can be used to delete all volume shadow copies on a system - vssadmin.exe delete shadows /all /quiet * Windows Management Instrumentation can be used to delete volume shadow copies - wmic shadowcopy delete * wbadmin.exe can be used to delete the Windows Backup Catalog - wbadmin.exe delete catalog -quiet * bcdedit.exe can be used to disable automatic Windows recovery features by modifying boot configuration data - bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures & bcdedit /set {default} recoveryenabled no

Inhibit System Recovery Mitigation

Consider technical controls to prevent the disabling of services or deletion of files involved in system recovery. Consider implementing IT disaster recovery plans that contain procedures for taking regular data backups that can be used to restore organizational data.(Citation: Ready.gov IT DRP) Ensure backups are stored off system and is protected from common methods adversaries may use to gain access and destroy the backups to prevent recovery. Identify potentially malicious software and audit and/or block it by using whitelisting(Citation: Beechey 2010) tools, like AppLocker,(Citation: Windows Commands JPCERT)(Citation: NSA MS AppLocker) or Software Restriction Policies(Citation: Corio 2008) where appropriate.(Citation: TechNet Applocker vs SRP)

Operating System Configuration

Make configuration changes related to the operating system or a common feature of the operating system that result in system hardening against techniques.

Data Backup

Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise.

Обнаружение

Use process monitoring to monitor the execution and command line parameters of binaries involved in inhibiting system recovery, such as vssadmin, wbadmin, and bcdedit. The Windows event logs, ex. Event ID 524 indicating a system catalog was deleted, may contain entries associated with suspicious activity. Monitor the status of services involved in system recovery. Monitor the registry for changes associated with system recovery features (ex: the creation of HKEY_CURRENT_USER\Software\Policies\Microsoft\PreviousVersions\DisableLocalPage).
