Fake ChatGPT Chrome Browser Extension Caught Hijacking Facebook Accounts

Google has stepped in to remove a bogus Chrome browser extension from the official Web Store that masqueraded as OpenAI's ChatGPT service to harvest Facebook session cookies and hijack the accounts.

The "ChatGPT For Google" extension, a trojanized version of a legitimate open source browser add-on, attracted over 9,000 installations since March 14, 2023, prior to its removal. It was originally uploaded to the Chrome Web Store on February 14, 2023.

According to Guardio Labs researcher Nati Tal, the extension was propagated through malicious sponsored Google search results that were designed to redirect unsuspecting users searching for "Chat GPT-4" to fraudulent landing pages that point to the fake add-on.

Installing the extension adds the promised functionality – i.e., enhancing search engines with ChatGPT – but it also stealthily activates the ability to capture Facebook-related cookies and exfiltrate it to a remote server in an encrypted manner.

Once in possession of the victim's cookies, the threat actor moves to seize control of the Facebook account, change the password, alter the profile name and picture, and even use it to disseminate extremist propaganda.
