Access To Chromium Browsers Sensitive Files By Uncommon Applications
This rule detects attempts by uncommon processes to access sensitive files associated with Chromium-based browsers. These files typically contain user data such as cookies, browsing history, and web data, which could be leveraged for credential access or other malicious activities if exfiltrated. The rule specifically targets file paths related to Chromium's user profile data and filters out access by common system processes and known legitimate applications like Windows Defender to reduce false positives.
