Detects post-exploitation persistence artifacts on Windows endpoints consistent with abuse of CVE-2026-18577.
Detects instances where VLC media player is launched from common temporary or untrusted directories (e.g., Downloads, Temp) with media files and subsequently crashes within a short window (2 minutes), as indicated by a corresponding werfault.exe error report. This behavior may indicate an attempt to exploit vulnerabilities within the VLC application by using a maliciously crafted file.
Detects the use of the MinHook library to hook CreateThread and spoof the thread start address as AnimateWindow, a technique used by the SparroWocky malware to conceal its true thread origin from security monitoring tools.
Detects unauthorized remote access sessions within N-able N-central by monitoring the Windows Application log for events indicating usage of the default 'MSP Support' account or source IP addresses associated with active exploitation of CVE-2026-18577.
Detects post-exploitation persistence artifacts on Windows endpoints consistent with abuse of CVE-2026-18577.
Detects unauthorized remote access sessions within N-able N-central by monitoring the Windows Application log for events indicating usage of the default 'MSP Support' account or source IP addresses associated with active exploitation of CVE-2026-18577.
Detects the installation of MSIX/AppX packages with full trust privileges which run with elevated privileges outside normal AppX container restrictions
Detects unexpected crashes of major security software agents (e.g., Antivirus, EDR) that are not associated with authorized vendor update or installation activities, potentially indicating tampering or exploitation attempts to disable security controls.

Detects post-exploitation persistence artifacts on Windows endpoints consistent with abuse of CVE-2026-18577.
Detects the clearing of Windows event logs using the native 'wevtutil.exe' command or the PowerShell 'Clear-EventLog' cmdlet. This activity is commonly associated with anti-forensic techniques used by threat actors and wiper malware to obstruct incident response efforts and remove traces of malicious activity.
Detects Windows Application Error events where the faulting module is 'nvoglv64.dll'. This is indicative of a crash in the NVIDIA OpenGL/Vulkan user-mode driver, which may be associated with the exploitation of the GreenSection shared-memory corruption vulnerability.
Detects N-able N-central Take Control remote session start/end events in the Windows Application log where the viewer identity is the default N-central support account 'MSP Support' / mspsupport@n-able.com, or the source/viewer IP matches known attacker infrastructure associated with active exploitation of CVE-2026-18577.
Detects inline execution of PowerShell code from a file
Detects unexpected crashes of major security software agents (e.g., Antivirus, EDR) that are not associated with authorized vendor update or installation activities, potentially indicating tampering or exploitation attempts to disable security controls.
This rule monitors the Windows Application event log for critical Microsoft SQL Server (MSSQL) events. It detects server crashes, access violations, stack overflows, and high-severity (20+) errors. These events often indicate severe database corruption, underlying system instability, or potential exploitation attempts targeting the database engine.
Detects attempts to install unsigned MSIX/AppX packages using the -AllowUnsigned parameter via AppXDeployment-Server events
This rule monitors the Windows Application event log for critical Microsoft SQL Server (MSSQL) events. It detects server crashes, access violations, stack overflows, and high-severity (20+) errors. These events often indicate severe database corruption, underlying system instability, or potential exploitation attempts targeting the database engine.
Detects the invocation of the Windows Error Reporting service (WerFault.exe) where the command line arguments reference Zoom-related processes (Zoom.exe, CptHost.exe, or zoom.us). This behavior is often indicative of an abnormal application crash, which may be associated with memory corruption exploitation attempts against the Zoom client.
