This isn't ChatGPT's fault so much as users who downloaded some malware & didn't turn on the 2-FA setting on their ChatGPT. Also affected is any sort of login data, crypto wallets, email apps, and pretty much anything scrapeable on a computer. The reason why the event is newsworthy is because some people input sensitive data in their ChatGPT sessions which can be valuable to hackers who will use it for nefarious purposes.
So if you're extra paranoid, change your ChatGPT password and clear your chat histories.
