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.

    Politeness is a ladder. The extension isn’t still malicious: it does what it says. It just the tradeoff is getting your API credentials stolen. Calling twitchenhancedviewer “obfuscated” is pure disinformation, as we can both see both codes, Firefox’s & Chrome’s.
