Detects the use of the sc.exe utility to disable critical system, security, and database services, a technique commonly associated with Everest ransomware to prevent service restart during encryption activities.
This rule identifies Windows Server devices, specifically potential Domain Controllers, that are flagged as vulnerable to CVE-2026-27912 (ResetNightmare) and CVE-2026-25177 (KerberLoss). It checks for the absence of the March/April 2026 cumulative updates that address critical Kerberos Change Password and Service Principal Name (SPN) logic flaws.
Detects Microsoft Edge being launched in a headless state with remote debugging enabled, hidden window dimensions, and a specific temporary user data directory naming convention. This pattern is characteristic of the TWINLOOT technique, where an adversary controls a headless browser via the Chrome DevTools Protocol (CDP) to conduct C2 communications and data exfiltration through legitimate Microsoft Graph API endpoints, effectively blending malicious traffic with normal browser activity.
Detects DLL sideloading across the SilkParasite campaign's five signed/trusted host binaries: MpDefenderCoreService.exe loading mpclient.dll (DriveSilkRAT), ebook-edit.exe loading calibre-launcher.dll (SpiceRAT), Mp3tag.exe loading tak_deco_lib.dll (CookiETagRAT), FineReader.exe loading dsp_ippv2_x64.dll (BloodAlchemy), and Acrobatlog.exe loading scansts.dll (NomadRAT).
KQL Query from file: T1546.003: WMI Realtek-named EventFilter/Consumer Triggers RtkNGUI64.exe Backdoor
Detects Python worker processes (e.g., dataset converters) spawning suspicious child processes (shells, network tools) or accessing sensitive filesystem paths/endpoints, such as Kubernetes service account tokens or cloud instance metadata, which are often indicative of post-exploitation activity following an SSTI or code injection vulnerability.
Detects the execution of known remote monitoring and management (RMM) or remote access tools shortly after Microsoft Teams process activity on a host. This behavior is consistent with helpdesk-impersonation vishing attacks where an adversary convinces a user to initiate a remote session.
Detects potential post-exploitation activity originating from the SharePoint worker process (w3wp.exe). The rule monitors for three primary indicators: w3wp.exe spawning command interpreters (cmd.exe or powershell.exe), unauthorized file modifications or creations within SharePoint web directories, and outbound network connections to public IP addresses initiated by w3wp.exe, which may indicate payload delivery or C2 communication. (CVE-2026-50522)
Detects instances where a process other than the legitimate Discord client or its updater accesses the Local Storage/leveldb directory. This path contains cached authentication tokens and session data, making it a frequent target for credential theft malware such as SectopRAT in the FakeAgent campaign.
Detects cross-process memory operations and CreateRemoteThread calls targeting explorer.exe or svchost.exe from non-standard (untrusted) process paths. This activity is consistent with StealC infostealer unpacking and injection behavior, typically following initial execution by SmartLoader as seen in recent FakeGit/AgentBaiting campaigns.
