Forensic analysis of browser history on Linux – reconstructing the web usage of Linux users

Even on Linux, popular web browsers such as Firefox and Chromium store detailed history of visited websites, downloads carried out and, in some cases, saved form data in user-specific profile files.

These profile files are usually located in the respective user’s home directory and can be analysed using comparable forensic methods, regardless of the browser used.

This is how a browser history analysis works on Linux

Once the relevant browser profile files have been backed up, they are analysed using specialised evaluation methods. Browsing history, downloads and other usage data are organised chronologically and correlated with other system artefacts.

Why is browser history analysis relevant in a forensic context?

Browsing history can provide direct evidence of a user’s actual internet usage, for example in connection with research into a planned action or access to compromising content.

Downloaded files and their origins can also often be traced via the browser’s download history, which may be relevant when determining the source of specific files.

Frequently Asked Questions

Which browsers are typically tested on Linux?+
In particular, Firefox and Chromium-based browsers such as Google Chrome, each of which uses specific but comparable profile data structures.
Can deleted history entries be recovered?+
To some extent, depending on the browser’s database technology and the time at which the data is deleted.
Are private or incognito sessions also tracked?+
These deliberately leave significantly fewer persistent traces, which is why additional system artefacts are used here to supplement the data.
