Matches published SHA-256 hashes for the Kothamine Injector and Agent DLL, which drop MicrosoftEdgeUpdateCore.exe/.dll and inject into explorer.exe. Exact full-file SHA-256 match only, no fuzzy or partial matching, no additional PE structural checks.

Detects the presence of the Amatera secondary-payload archive component, which consists of a legitimate signed Chrome executable (platform_experience_helper.exe) paired with a malicious NativeAOT-compiled Secur32.dll designed for DLL side-loading. The malicious DLL is identified by its interaction with the GetUserNameExW Windows API.
Detects bulk or repeated attempts to stop security-related services and processes (such as EDR or AV agents) or modification of Windows Defender registry keys. This behavior is indicative of a pre-encryption phase in ransomware attacks where adversaries attempt to neutralize endpoint defenses.
Detects the presence of the i-Realm companion tool associated with the AnonyMousKIT PhaaS platform, which is designed to bypass iOS Activation Lock features.
Detects a malicious payload masquerading as a ClaudeDesktop installer that uses DLL sideloading via a tampered libcef.dll and a repurposed JetBrains binary to execute the SectopRAT .NET RAT.
Detects the use of a malicious 'borlndmm.dll' file intended for DLL side-loading to deploy the OnyxC2 stealer payload. The rule identifies files masquerading as NVIDIA graphics libraries or Borland memory managers that contain embedded encrypted payloads, matching known indicators for OnyxC2 activity.
Detects the reflectively-loaded SectopRAT .NET payload by its combination of heavy calli (indirect call) opcode usage for control-flow flattening and its characteristic runtime string-decryption helper method used to resolve the C2 IP/port and other obfuscated strings
Matches known SHA-256 hashes of AvisLoader toolkit components recovered from an exposed staging server: the Windows loader client, UAC-bypass helper, and process-hiding DLL
Detects the use of PowerShell cmdlets (Add-MpPreference or Set-MpPreference) to modify Microsoft Defender exclusions (paths, processes, or extensions). This behavior is often associated with adversaries attempting to evade security detection by excluding malicious files or processes from being scanned by Microsoft Defender.
This rule detects the deletion of critical Windows Defender security files (such as drivers and executables) by the System process. This behavior is highly indicative of an attempt to tamper with or disable security features on a host.
Detects files matching known SHA256 hashes of the masqueraded MSP360 RMM v2.5.0.67 installer and associated ScreenConnect/utility payloads used in phishing-to-dual-RMM campaigns
Detects files matching known SHA256 hashes of the masqueraded MSP360 RMM v2.5.0.67 installer and associated ScreenConnect/utility payloads used in phishing-to-dual-RMM campaigns
Detects files matching known SHA256 hashes of the masqueraded MSP360 RMM v2.5.0.67 installer and associated ScreenConnect/utility payloads used in phishing-to-dual-RMM campaigns
Detects the use of PowerShell to modify Microsoft Defender settings to add an exclusion path within the AppData directory. This behavior is often associated with malware or threat actors attempting to whitelist malicious payloads to evade security scanning.
This rule uses YARA to identify specific malicious files associated with the Sauron Loader malware, including the MSI installer and associated support DLLs (rnp.dll, tdwp.dll), based on their known SHA-256 hashes.
This rule detects a suspicious sequence of events where a process related to Electron (a framework often used for cross-platform desktop applications) executes a hidden, obfuscated PowerShell command, followed by a subsequent PowerShell command to modify Microsoft Defender settings by adding an exclusion path for the 'AppData' directory within 10 minutes of the first process.
Detects the execution or presence of a malicious MSI installer file used by the Sauron Loader. This rule identifies files that exhibit the MSI OLE compound file structure in conjunction with specific file paths (C:\ProgramData\keyroll) and the presence of identified malicious components (rnpkeys.exe, rnp.dll, and tdwp.dll), or matches known SHA256 file hashes associated with this loader.
Detects attempts to disable Windows Defender by either executing known Defender Control utilities or by modifying registry keys associated with the disabling of anti-spyware features or the WinDefend service startup.
Detects the use of PowerShell to modify Windows Defender configuration settings, specifically targeting the disabling of real-time monitoring, behavioral monitoring, or other security protections via the Set-MpPreference cmdlet.
