Detects GitHub self-hosted runners executing workflows on local infrastructure that could be abused for persistence and code execution.
Shai-Hulud is an npm supply chain worm targeting CI/CD environments.
It installs runners on compromised systems to maintain access after credential theft, leveraging their access to secrets and internal networks.

Detects potential ClickFix malware execution patterns by monitoring registry modifications in RunMRU keys containing HTTP/HTTPS links.
ClickFix is known to be distributed through phishing campaigns and uses techniques like clipboard hijacking and fake CAPTCHA pages.
Through the fakecaptcha pages, the adversary tricks users into opening the Run dialog box and pasting clipboard-hijacked content,
such as one-liners that execute remotely hosted malicious files or scripts.

Detects suspicious commands that are related to scripting/powershell in WMI Event Consumers
Detects an appx package that was added to the pipeline of the "to be processed" packages that is located in uncommon locations.
Detects DNS queries made by the finger utility, which can be abused by threat actors to retrieve remote commands for execution on Windows devices.
In one ClickFix malware campaign, adversaries leveraged the finger protocol to fetch commands from a remote server.
Since the finger utility is not commonly used in modern Windows environments, its presence already raises suspicion.
Investigating such DNS queries can also help identify potential malicious infrastructure used by threat actors for command and control (C2) communication.

Detects suspicious FileFix execution patterns where users are tricked into running malicious commands through browser file upload dialog manipulation.
This attack typically begins when users visit malicious websites impersonating legitimate services or news platforms,
which may display fake CAPTCHA challenges or direct instructions to open file explorer and paste clipboard content.
The clipboard content usually contains commands that download and execute malware, such as information stealing tools.

Detects commonly-used chained commands and strings in the most recent 'url' value of the 'TypedPaths' key, which could be indicative of a user being targeted by the FileFix technique.
Detects attempts to query system information directly from the Windows Registry.
Detects the initial execution of "cmd.exe" which spawns "explorer.exe" with the appropriate command line arguments for opening the "My Computer" folder.
Detects COM object hijacking via TreatAs subkey
