The rule titled 'Access to Browser Login Data' identifies potential credential acquisition attempts by monitoring PowerShell script block logging. Adversaries target web browsers to obtain saved usernames and passwords, which are typically stored in an encrypted format within browser-specific credential stores. This rule leverages the characteristics of malicious PowerShell commands that may involve copying files or accessing specific paths related to popular browsers like Chrome, Firefox, Edge, and Opera. The rule activates when script blocks containing load commands for the specified browser paths indicative of adversary behavior are detected. As web browsers save credentials for user convenience, unauthorized access to these credential stores poses a significant security risk.
