Threat Research Team identified a cross-store browser extension, “Twitch Enhanced Viewer | JeetBot,” that forwards each user’s live Twitch OAuth session token to proxy servers operated by a Russian commercial bot service. The extension ships on both the Chrome Web Store (extension ID pnhhdhhcadcjfckjhpmjneldiegbojfb, 30,000 users) and Firefox Add-ons (twitchenhancedviewer@example.com, 552 users). Both listings are live at time of writing.


For Twitch it does, they inline the video ads with the stream, uBlock can’t do anything about that, and if you have a blocker that does work Twitch just infinitely refreshes the stream trying to force the video ad.
