Chromagnon is a set of small tools dedicated to Chrome/Chromium forensic.

Tools

• ChromagnonHistory parses Chrome History file
• ChromagnonCache parses Chrome Cache files
• ChromagnonVisitedLinks can verify if urls are in Chrome Visited Links file
• ChromagnonDownload parses Chrome Downloaded Files database

Requirements

• Python 2.7

Remarks

• Most of the code is Endianness dependant and tested only on little endian hosts
• The code is alignment dependant. If Chrome was compiled with custom alignment flags, it probably won't work.

Work In Progress

I am working on reverse engineering SSNS file format : see this page for details.

Tests

Following cases have been tested with success

• Chromagnon on FreeBSD 9.0 amd64 parsing file from Windows 7 64bits (Chrome 20)
• Chromagnon on FreeBSD 9.0 amd64 parsing file from Linux Mint 12 amd64 (Chrome 18)
• Chromagnon on FreeBSD 9.0 amd64 parsing file from FreeBSD 9.0 amd64 (Chrome 15)
• Chromagnon on Arch Linux x86_64 parsing file from Arch Linux x86_64 (Chrome 20)

Help is welcome to test Chromagnon on other plateforms.
