The visits table contains the URL id, the last visit time, and the “transition” field. This will run much faster, but will have a limited amount of information. If only the data from the visits table is desired, the -Q, for QUICK, option can be given. The default behavior of the plugin is to call the chromehistory plugin internally, then search for visits records and combine the data before printing. The visits tables doesn’t contain the actual URLs that were visited those are stored in the urls table, so a SQL JOIN is needed to combine the two.

The history table will just show the last visit to a specific URL along with a count of the number of visits.
If these entries are a problem, the -N will omit them from the output. These often have an invalid timestamp which gets displayed as the epoch time, or 1. There are no examples in the output below, but sometimes the plugin finds partial records where some data has been overwritten or is incomplete. This will omit any records found with a “null timestamp”. The plugin also supports a -N option, for NULLTIME. In addition, the last visit timestamp is used in the bodyfile. The URL may occasionally be truncated, but the full URL can be displayed in CSV format. The output contains, among other fields, the URL, page title, number of visits, and the last visit time. The full output from the sample image is copied below with all 15 records that are in the chrome_history database linked to above, showing the plugin was able to locate them all. The chromehistory plugin extracts records from the Chrome urls table in the History SQLite database file. Usage and output for the plugins is below.
According to W3Schools, Firefox and Chrome make up about 85% of the browser share as of July 2014, so this and my other plugin in the contest help round out Volatility’s browser coverage. This is useful for combining with other plugins to create a timeline. It can print output in the default table format or in CSV or bodyfile format. Like the core Volatility module iehistory, this module adds similar functionality for Chrome browsing history. There are some slight differences between the schemas in these versions and the plugins should handle them, and presumably versions in between. I’ve tested the plugins on Chrome 30 and Chrome 37. Depending on the number and type of fields in each table, certain values can be expected in certain positions, which allows us to locate records of a given table.Ī sample memory image is available at voltest.zip, and the corresponding History and Cookies files from that image are at chrome_history and chrome_cookies, respectively, for comparison with the plugin output. Firefox and Chrome both store history and browsing data in SQLite databases. They also depend on the sqlite_help.py module in the same location, which provides some useful functions for manipulating data in SQLite databases. They are all in the chromehistory.py module found on my volatility-plugins repo on GitHub. As part of the 2014 Volatility Plugin Contest, I created 6 plugins for locating Chrome browser history related artifacts:
