Detects GitHub repository actions (git.clone, oauth_authorization.create, repo.download_zip) from actor IPs not seen for that user in the prior 30 days, requiring either 3+ actions or activity across 2+ distinct repositories from the new IP within the same day. Aggregating to burst/multi-repo behavior (rather than alerting on a single new-IP event) filters out one-off false positives from travel, VPNs, or dynamic IP reassignment while still surfacing sustained anomalous access patterns consistent with account compromise or bulk exfiltration.

Detects the exfiltration behavior of the Sauron Loader, where a process tree associated with rnpkeys.exe or its modules (rnp.dll, tdwp.dll) within the C:\ProgramData\keyroll directory performs a burst of numerous small HTTPS POST requests to a single destination. This pattern is characteristic of a screenshot image being fragmented into small chunks and exfiltrated.

The following analytic identifies when an O365 email account sends an excessive number of email attachments to external recipients within a short period (within 1 hour).
This behavior may indicate a compromised account where the threat actor is attempting to exfiltrate data from the mailbox.
Threat actors may attempt to transfer data through email as a simple means of exfiltration from the compromised mailbox.
Some account owner legitimate behaviors can trigger this alert, however these actions may not be aligned with organizational expectations / best practice behaviors.

Detects communication patterns associated with the RatHat Android banking trojan. The rule identifies a multi-stage C2 flow: first, the device fetches malicious overlay configurations (templates for spoofed login screens) and subsequently exfiltrates captured credentials or form data to the adversary's infrastructure via POST requests.

Detects the installation of known AI-powered coding assistant extensions (e.g., Copilot, Tabnine, Cursor) on a device, followed by significant source-code repository cloning or archival activity by Git within two hours. This pattern is potentially indicative of intellectual property theft or sensitive source code exfiltration facilitated by a newly introduced AI tool.
