Description
This analytic focuses on identifying non-chrome processes that attempt to access the Chrome extensions file. This file contains crucial settings and information related to the browser’s extensions installed on the computer. Adversaries and malware authors have been known to exploit this file to extract sensitive information from the Chrome browser on targeted hosts. Detecting such anomalous behavior provides valuable insights for analyzing suspicious processes beyond the commonly observed chrome.exe and explorer.exe executables. By monitoring for access to the Chrome extensions file by non-chrome processes, we can enhance our ability to detect potential threats and protect sensitive information stored within the browser.
