We will use Group Policy Editor to set up Process Creation Auditing. Enabling Process Creation Event LogsĮnabling Process Creation auditing will create Event ID 4688 and other necessary details such as Process Path, Parent, Command line, etc, using which we can monitor for malicious command lines. We need to get process creation logs to monitor for known malicious command lines and file access logs to monitor unauthorised access to browser files. To set up correct monitoring and detection of browser credential extraction, we need to enable auditing features in Windows to receive logs. Hackbrowserdata procmon log graph view in Vision-procmonĪnalysing the procmon logs of various open and closed source tools, we can confirm that all tools access fixed paths where the browsers store their data(such as cookies, credentials, history) and then process these files to extract credentials.ĭetecting Unauthorized Access to Browser Files Direct integration to C2 Frameworks such as Metasploit's post/multi/gather/firefox_creds and post/windows/gather/enum_chrome modules allow quick access to browser passwords for adversaries. Tools such as Lazagne and HackerBrowserData are open source and provide customizability to advanced attackers, whereas tools such as Nirsoft’s WebBrowserPassView are closed source and cannot be modified easily. There are various tools, open source and closed, which adversaries use for stealing credentials from browsers. This post will showcase how to detect browser credential extraction, weed out false positives, and improve our resilience against this threat. These credentials are made available to threat actors who use these credentials to breach various organizations. Malware such as Redline Stealer, Zaraza bot, and other info stealers have been actively targeting users and organizations to gain access to browser credentials.

People save login credentials in browsers to make the login process faster.
