717165 - Malicious "Youtube player" Add-On

Status: RESOLVED FIXED

(Toolkit :: Blocklist Policy Requests, defect)

Description

[MarkH]

Attachment: YXH-youtube_player.xpi.zip

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_2) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.75 Safari/535.7

Steps to reproduce:

Downloaded and installed the "Youtube player" add-on from a malicious site, http://bbpeonf14.blogspot[.]com/.

The malicious add-ons is currently hosted at http://anyhub[.]net/file/7av-youtube_player.xpi



Actual results:

Once installed, this add-on injects a series of <script> tags and hidden <iframes> into the DOM.  Those script tags and iframes continually reload a series of banner ads, to generate revenue for the add-on authors.

It provides no service to the user/victim, does not do what it claims (play Youtube videos), and brings browser performance to a crawl.


Expected results:

It shouldn't have done anything it actually did.
