Summary
This detection rule identifies suspicious activity related to TCC (Transparency, Consent, and Control) access grants on macOS systems. Specifically, it aims to detect when an application is granted access to multiple user folders such as Desktop, Downloads, and Documents in a rapid succession, which might indicate an information stealer trying to manipulate TCC to gain unauthorized access for data exfiltration. The use of scripting interpreters or command-line tools for repeated TCC permission grants is a red flag that can suggest malicious activity. Environments should have monitoring mechanisms to investigate and respond to these incidents promptly to prevent unauthorized data access and potential breaches.
