I’ve been documenting lots of potentially malicious browser extensions in Chrome Web Store [1] [2] [3]. As the lists of affected extension IDs are getting long and difficult to keep track of, I decided to add them to this repository (see list.txt).

Note: Some extensions listed are no longer available via Chrome Web Store. If they were installed prior to removal however, they often remain installed.

Instead of checking extension IDs against the list manually, you can also download the check-extensions utility. When run without parameters, it will try locating all browser profiles of Chrome and Chromium-based browsers under your user account. A list of browser profiles to check can also be given explicitly as command line parameters.
