Detects unauthorized execution of wermgr.exe from suspicious paths or spawned by Task Scheduler service (svchost.exe/taskeng.exe) with non-standard parent processes. This behavior is indicative of privilege escalation attempts where an unprivileged process leverages the Windows Error Reporting (WER) QueueReporting scheduled task to execute a malicious payload in the context of the SYSTEM account.
Detects anomalous instances of conhost.exe running with SYSTEM integrity within an interactive user logon session. This behavior is indicative of session hijacking techniques, such as those leveraging named pipes or LaunchConsoleInSessionId, used to force console hosts into user-controlled sessions to potentially capture input or manipulate processes.
This rule detects the creation of or connection to a specific named pipe '\RoguePlanet' using Windows Sysmon events 17 (Pipe Created) and 18 (Pipe Connected). It further highlights events where the integrity level of the process interacting with the pipe is 'low' or 'medium', which may indicate potential inter-process communication (IPC) abuse, process injection, or malicious persistence mechanisms often used by attackers to mask execution or communicate between processes.
Detects signs of a supply chain attack, specifically referencing the IronWorm/Shai-Hulud pattern, involving the backdating of git commits, manipulation of git environment variables (GIT_COMMITTER_DATE/GIT_AUTHOR_DATE) to mask malicious activity history, and the use of 'touch' commands to modify file timestamps on project-related binaries and configuration files.
Detects OAuth consent grants or permission additions in Microsoft Entra ID (Azure AD) audit logs that occur in conjunction with device login flow artifacts. This pattern is indicative of 'ConsentFix' or device code phishing attacks, where users are manipulated into authorizing malicious applications, potentially bypassing MFA requirements by using the device code flow.
This rule monitors registry modifications targeting Windows Defender policies and Sysmon service configuration. Specifically, it tracks attempts to disable real-time protection, anti-spyware features, and service settings commonly used by adversaries to impair security monitoring and defensive tools, characteristic of defense impairment tradecraft.
Detects attempts to disable or tamper with Microsoft Defender Antivirus settings, services, or processes. This includes the use of Set-MpPreference to change configuration, service control (sc) to stop the WinDefend service, process termination via taskkill, or the execution of known removal scripts like DisableDefender.ps1.
Detects malicious activities targeting Cisco Catalyst SD-WAN infrastructure, including connections from known malicious IP addresses (UAT-8616), unauthenticated vManage API access attempts indicative of exploitation (CVE-2026-20182), and anomalous control-plane signaling (OMP/DTLS/NETCONF) from unauthorized external sources.
Detects the presence and execution of RustDesk remote access software by monitoring process names, command-line arguments, specific destination network ports, and DNS queries associated with the application. This rule identifies potential unauthorized remote access attempts or the use of non-approved remote support tools.
Detects post-compromise persistence techniques, including crontab modifications, SSH authorized_keys updates, and systemd service creation, when performed by child processes of AI agentic tools like Claude, Node.js, or Python. This activity suggests malicious persistence establishment following an indirect prompt injection or supply-chain compromise of the AI agent environment.
