Detects a sequence of events where a user clicks a shared link to an AI chatbot conversation followed closely (within 15 minutes) by the execution of potentially malicious processes (mshta, powershell, cmd) that include suspicious command-line patterns indicative of ClickFix-style social engineering.
This rule detects potential ClickFix/InstallFix attacks where a user is socially engineered to copy and paste a malicious command from a website that mimics a legitimate developer tool installation (e.g., Claude Code, NotebookLM). The detection flags the use of common download-and-execute cmdlets (e.g., irm, iwr, iex) within common Windows shell interpreters while excluding known legitimate vendor install domains.
Detects a sequence of potentially malicious local command execution (via PowerShell, cmd, or mshta) that mirrors the 'ClickFix' social engineering pattern, followed by an OAuth application consent grant or device-code authorization by the same user within a short timeframe. This behavior is indicative of an adversary attempting to bypass MFA by tricking a user into authorizing a malicious application after establishing local execution on their endpoint.
Detects potential consent phishing attempts by identifying when a user grants high-risk, persistent-access OAuth scopes (such as Mail or Files) to a new third-party application. The rule specifically excludes known first-party Microsoft apps and utilizes a lookback period to avoid alerting on applications that have already been consented to within the tenant, reducing noise from routine enterprise app usage.
This rule detects potential persistence mechanisms associated with the GlobalProtect VPN application where the binary is unsigned. It specifically monitors for unauthorized 'RunOnce' registry entries, the creation of suspicious scheduled tasks, or updates to scheduled tasks involving 'GlobalProtect.exe'. These actions are initiated by either 'msiexec.exe' or 'GlobalProtect.exe', suggesting a possible attempt to masquerade malicious activity as a legitimate VPN update or installation process.
Detects a suspicious sequence of events involving NetScaler ADC or Gateway appliances: anomalous account authentication, followed by the establishment of a VPN or remote access session, and subsequent unusual outbound network activity indicating potential lateral movement or C2 communication from the appliance.

Detects high-risk GitHub events indicating data or asset exposure, such as creating public repositories with specific naming conventions, changing private repositories to public, or creating new gists, which could indicate exfiltration of sensitive assets or information.
Detects a suspicious pattern where an AI coding agent or user creates a public GitHub repository with specific naming conventions (e.g., 'sweeper-demo', 'gitshot-images') and subsequently pushes content containing sensitive terms like 'screenshot' within a short timeframe. This behavior is indicative of potential data exfiltration of internal development screenshots to a public repository.
