MITRE ATT&CK - Técnica

T1490: Inhibit System Recovery

Inhibit System Recovery (T1490) é uma técnica catalogada no MITRE ATT&CK Enterprise usada como referência para mapear comportamento adversário em auditorias de segurança.

Técnica T1490 Enterprise ATT&CK

Contexto para AppSec

Em uma auditoria de AppSec, Inhibit System Recovery deve ser usada para revisar caminhos em que código, configuração, dependências ou infraestrutura podem viabilizar o comportamento descrito pela MITRE. No ATT&CK, ela aparece em Impact. As plataformas mapeadas pela MITRE incluem Containers, ESXi, IaaS, Linux, macOS, Network Devices e Windows. No Vigly, esse contexto ajuda a conectar evidências do repositório com priorização e remediação.

Descrição oficial original do MITRE ATT&CK

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. 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. 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
  • REAgentC.exe can be used to disable Windows Recovery Environment (WinRE) repair/recovery options of an infected system
  • diskshadow.exe can be used to delete all volume shadow copies on a system - diskshadow delete shadows all On network devices, adversaries may leverage Disk Wipe to delete backup firmware images and reformat the file system, then System Shutdown/Reboot to reload the device. Together this activity may leave network devices completely inoperable and inhibit recovery operations. On ESXi servers, adversaries may delete or encrypt snapshots of virtual machines to support Data Encrypted for Impact, preventing them from being leveraged as backups (e.g., via vim-cmd vmsvc/snapshot.removeall). 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.
