Уничтожение данных

Adversaries may destroy data and files on specific systems or in large numbers on a network to interrupt availability to systems, services, and network resources. Data destruction is likely to render stored data irrecoverable by forensic techniques through overwriting files or data on local and remote drives.(Citation: Symantec Shamoon 2012)(Citation: FireEye Shamoon Nov 2016)(Citation: Palo Alto Shamoon Nov 2016)(Citation: Kaspersky StoneDrill 2017)(Citation: Unit 42 Shamoon3 2018)(Citation: Talos Olympic Destroyer 2018) Common operating system file deletion commands such as del and rm often only remove pointers to files without wiping the contents of the files themselves, making the files recoverable by proper forensic methodology. This behavior is distinct from Disk Content Wipe and Disk Structure Wipe because individual files are destroyed rather than sections of a storage disk or the disk's logical structure. Adversaries may attempt to overwrite files and directories with randomly generated data to make it irrecoverable.(Citation: Kaspersky StoneDrill 2017)(Citation: Unit 42 Shamoon3 2018) In some cases politically oriented image files have been used to overwrite data.(Citation: FireEye Shamoon Nov 2016)(Citation: Palo Alto Shamoon Nov 2016)(Citation: Kaspersky StoneDrill 2017) To maximize impact on the target organization in operations where network-wide availability interruption is the goal, malware designed for destroying data may have worm-like features to propagate across a network by leveraging additional techniques like Valid Accounts, OS Credential Dumping, and SMB/Windows Admin Shares.(Citation: Symantec Shamoon 2012)(Citation: FireEye Shamoon Nov 2016)(Citation: Palo Alto Shamoon Nov 2016)(Citation: Kaspersky StoneDrill 2017)(Citation: Talos Olympic Destroyer 2018). In cloud environments, adversaries may leverage access to delete cloud storage, cloud storage accounts, machine images, and other infrastructure crucial to operations to damage an organization or their customers.(Citation: Data Destruction - Threat Post)(Citation: DOJ - Cisco Insider)

Data Destruction Mitigation

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)

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.


Use process monitoring to monitor the execution and command-line parameters of binaries that could be involved in data destruction activity, such as SDelete. Monitor for the creation of suspicious files as well as high unusual file modification activity. In particular, look for large quantities of file modifications in user directories and under C:\Windows\System32\. In cloud environments, the occurrence of anomalous high-volume deletion events, such as the DeleteDBCluster and DeleteGlobalCluster events in AWS, or a high quantity of data deletion events, such as DeleteBucket, within a short period of time may indicate suspicious activity.
