Launch Agent/Daemon Execution Via Launchctl

Detects the execution of programs as Launch Agents or Launch Daemons using launchctl on macOS.

Detection logic

Detection requirements

Platform: macOS
The rule states no platform. This is derived from the 2 ATT&CK techniques it maps to.
Log source product: macos
Log source category: process_creation

Known benign triggers

Legitimate administration activities is expected to trigger false positives. Investigate the command line being passed to determine if the service or launch agent are suspicious.

Windows Wermgr Alternate Data Stream in Temp Dir

The following analytic detects the wermgr.exe process creating an alternate stream in the temp directory. It leverages Sysmon EventID 15 to identify these actions. This activity is significant because wermgr.exe is typically associated with error reporting, not file creation. Such activity is significant as it may indicate RoguePlanet malware, which creates an alternate stream in the temp directory to execute malicious code.

Ollama Suspicious Prompt Injection Jailbreak

Detects potential prompt injection or jailbreak attempts against Ollama API endpoints by identifying requests with abnormally long response times. Attackers often craft complex, layered prompts designed to bypass AI safety controls, which typically result in extended processing times as the model attempts to parse and respond to these malicious inputs.

PingID New MFA Method After Credential Reset

The following analytic identifies the provisioning of a new MFA device shortly after a password reset. It detects this activity by correlating Windows Event Log events for password changes (EventID 4723, 4724) with PingID logs indicating device pairing. This behavior is significant as it may indicate a social engineering attack where a threat actor impersonates a valid user to reset credentials and add a new MFA device.
