KFC For Mac

KFC (Kill Flash Cookies) is a free and easy to use Mac OS X app which will try to delete all the Flash cookies on your system.

The Adobe Flash Player maintains proprietary cookies called Local Shared Objects or LSO’s. LSO’s are capable of storing 100 kb’s of information for an indefinite amount of time by default. When you clear your browser history on Windows, Linux, or Mac OS X LSO’s are not cleared from Adobe’s local repository.

In fact, all the information in those cookies will remain indefinitely until they’re removed by the issuing website, or by you via a cumbersome and ridiculous process.

These cookies can contain personal information such as usernames and passwords and due to the increasing security vulnerabilities in Flash it would make sense to delete those cookies and avoid malicious websites from reading the information stored in them.

KFC comes in two flavors: A command line application and a GUI version. Mac OS X, Linux and Windows are supported natively.

The KFC utility will search for Flash cookies in the following directory: ~/Library/Preferences/Macromedia/Flash Player.

IMPORTANT: The first time you run the program, please make sure to run it until there are no more errors. Flash cookies are notoriously resilience. It takes 3 or 4 passes to erase them all. You can run it with the option -v to see what's going on. It also might take some time to to complete the first run.
