Description Matthew Middleton (:zzxc) 2010-01-21 20:23:06 PST
Created attachment 422911 [details]
Copy of the extension, obtained from a user's global extensions folder

Several users today in Live Chat reported having an extension that is redirecting websites (,, and anything with 'search' in the url) to malicious sites.  I got a copy of the extension, which is attached to this bug.

The guid of the extension is {8CE11043-9A15-4207-A565-0C94C42D590D} , and several anti-malware programs are recognizing it as malware.  This GUID should be blocklisted for all versions of all applications.

morgamic, can we do this today? I confirmed the add-on hijacks all search results for Google, Yahoo, Bing, and AOL and masks itself as an "Internal security" add-on.

INSERT INTO `blitems` (`guid`, `min`, `max`) VALUES
('{847b3a00-7ab1-11d4-8f02-006008948af5}', null, null);

Would have to run that on prod and that's all we have to do.

Err, bad query, meant:

INSERT INTO `blitems` (`guid`, `min`, `max`) VALUES
('{8CE11043-9A15-4207-A565-0C94C42D590D}', null, null);
Comment 4 Michael Morgan [:morgamic] 2010-01-24 22:01:29 PST
This was pushed.  When/how should we publish the info on ?
Comment 5 Justin Scott [:fligtar] 2010-01-24 22:11:58 PST
We can do it whenever. Probably something like:

"Internal security" add-on, all versions for all applications. Reason: Secretly hijacks all search results in most major search engines masked as a security add-on.
