Detects anomalous bursts of deletion activity targeting Azure Site Recovery and Backup resources, including management locks and backup policies. This behavior is consistent with an adversary attempting to inhibit system recovery capabilities, often a precursor to destructive activities such as ransomware deployment. The rule also correlates this activity with the deletion of other critical infrastructure components like databases or storage accounts.
Detects Android applications that request Device Admin privileges followed by the execution of coercive commands, such as disabling biometric authentication, setting admin passwords, or enabling uninstall protection. This behavior is indicative of malicious applications (e.g., RatHat) aiming to establish persistence and prevent uninstallation by the user or security software.
Detects the use of native Windows utilities (vssadmin, wmic, wbadmin) or PowerShell cmdlets to delete Volume Shadow Copies or backup catalogs. This behavior is commonly associated with ransomware attempts to prevent system recovery.
Detects the use of native Windows utilities such as vssadmin.exe, wmic.exe, and diskshadow.exe to delete volume shadow copies. This is a common technique used by ransomware and other malware to prevent system recovery.
Detects ClickFix-style browser or explorer spawned command execution using clipboard-paste patterns, or subsequent ransomware-related discovery and inhibit-system-recovery commands such as net.exe, nltest.exe, and vssadmin.exe used after initial access.
Detects a sequence of suspicious activities on a Windows host aimed at inhibiting system recovery, such as deleting shadow copies, modifying boot recovery configurations, deleting backup catalogs, or stopping security and backup-related services. This rule aggregates distinct categories of these actions by DeviceId and Account to identify potential malicious intent characteristic of ransomware or data destructive attacks.
Detects the deletion of Volume Shadow Copies using the Windows Management Instrumentation Command-line (WMIC) utility. This behavior is commonly observed in ransomware attacks, including those attributed to DragonForce and CRPx0, as a method to inhibit system recovery prior to file encryption.
Detects suspicious activity on VMware ESXi hosts involving the termination or unregistration of virtual machines via 'esxcli' or 'vim-cmd', correlated with high volumes of file modification or creation events (.vmdk or .vmx files) within a short window. This pattern often indicates attempts to disrupt virtual machines or inhibit system recovery by adversaries.
Detects a sequence of suspicious activities associated with credential dumping and inhibiting system recovery. The rule tracks when a user account executes multiple commands related to volume shadow copies (vssadmin, rmdir, mklink) or attempts to copy sensitive registry files (SAM, SYSTEM, SECURITY) within a 15-minute window on the same device.
Detects attempts to delete Azure resource locks protecting Site Recovery or Backup services, followed by credential retrieval (ListKeys) within a one-hour window. This sequence pattern is a strong indicator of an adversary attempting to disable backup protection before potentially destroying data or exfiltrating keys.
Detects attempts to delete Azure resource locks protecting Site Recovery or Backup services, followed by credential retrieval (ListKeys) within a one-hour window. This sequence pattern is a strong indicator of an adversary attempting to disable backup protection before potentially destroying data or exfiltrating keys.
Detects attempts to delete Azure resource locks protecting Site Recovery or Backup services, followed by credential retrieval (ListKeys) within a one-hour window. This sequence pattern is a strong indicator of an adversary attempting to disable backup protection before potentially destroying data or exfiltrating keys.
This rule detects potential ransomware activity by correlating the execution of native Windows utilities used to inhibit system recovery (vssadmin, wmic, wbadmin, bcdedit) followed by a high volume of file modification events on the same host within a 15-minute window.
Detects the use of native Windows utilities (vssadmin, wmic, wbadmin, bcdedit) to delete volume shadow copies, backup catalogs, or disable recovery mechanisms. This behavior is commonly associated with ransomware or destructive attacks attempting to inhibit system recovery.
Detects the use of built-in Windows utilities and commands to disable system recovery features, delete volume shadow copies, clear backup catalogs, or perform mass file deletion. This behavior is highly indicative of wiper malware preparing for a destructive attack by preventing system recovery.
Detects the use of native system utilities including wmic, vssadmin, and wbadmin to delete Volume Shadow Copies or the Backup Catalog, as well as the deletion of local snapshots on macOS via tmutil. These actions are common techniques employed by ransomware to prevent system restoration after encryption.
Detects the execution of ReAgentC.exe with the /disable flag, which disables the Windows Recovery Environment (WinRE). This activity is often used by adversaries to prevent system recovery or to facilitate data impact, such as ransomware deployment.
Detects the use of native Windows tools like vssadmin and wmic to delete Volume Shadow Copies. This activity is a common indicator of ransomware or other destructive attacks attempting to inhibit system recovery.
Detects execution of the Windows diskpart utility using a script file, initiated by a process with a name ending in _win64.exe. This pattern is commonly used in malicious scripts for disk manipulation or inhibiting system recovery.
Detects execution of the Windows diskpart utility using a script file, initiated by a process with a name ending in _win64.exe. This pattern is commonly used in malicious scripts for disk manipulation or inhibiting system recovery.
This rule detects the use of standard Windows administrative utilities (wmic.exe, vssadmin.exe, and wbadmin.exe) to perform destructive operations on volume shadow copies or backup catalogs. These actions are frequently associated with ransomware attacks to prevent system recovery.
