Viewing Firefox’s Super Cookies


Pascal has a nice short post on Firefox’s “super cookies” and the information contained inside the browser’s DOM storage. He does a nice job describing comparing Adobe’s Flash local storage to this storage technology, and gives examples of how to view this data using sqlite3 in Unbuntu.

If you’re running Windows, you can try the open source SQLite Database Browser instead of sqlite3 to view the webappsstore.sqlite file, which is a binary file normally unreadable to humans. SQLite Database Browser allows you to browse the database as well as query it.

I think more and more Internet based data will be stored in this manner in the future, so I hope others will check out the information stored in this database file. I’m surely going to be examining the webappsstore.sqlite file the next time I need to perform any type of computer forensics information gathering on a computer.

    I guess I didn’t do such a great job because I confused you (so most likely many others) on the difference between Flash and DOM storage. They are different mechanisms, I just wanted to point out that DOM storage is less well known than Flash storage. Thanks for your kind comments.

    Pascal,

    Could we maybe entice you to elaborate on the differences between these technologies?

    Thanks – Julie
