Extracting Brave Browser artifacts from mobile devices

Brave Browser was created by Brendan Eich,  one of the two  co-founders of Mozilla. This privacy-focused browser is based on Google’s open-source Chromium code. The Brave Browser report shows that Brave now has over 36.2 million monthly active users and over 12.5 million daily active users. In several “best secure browser ratings of 2021”,  Brave Browser occupies the top position, even higher than the Tor Browser.

What makes it popular are the privacy features that are offered by default. Among them are:

  • Blocking of all ads, pop-ups, scripts, trackers, third-party cookies, and third-party storage
  • Upgrading insecure connections to HTTPS
  • The possibility to open a new private window with the Tor connectivity and DuckDuckGo default search engine, means that users can easily access the Dark web that is often associated with illegal activities

These secure features can be used for both good and bad. In this blog article, we will focus on how Brave Browser data can be extracted as digital evidence from mobile devices. Please note that a mobile version of Brave browser does offer the Tor connectivity, so this topic won’t be discussed here.

Currently, we are working on giving investigators accessibility to collect Brave Browser data on computers using Oxygen Forensic® Detective. Once support is implemented, we will share the details with you.
