Twitter announced yesterday that it patched a vulnerability in the Twitter for Android app that could have allowed a hacker to control a Twitter user's account and send tweets and DMs from it. The vulnerability also could have given a bad actor access to non-public information. Twitter says that it has no evidence that the vulnerability was ever exploited, but just to play it safe it is "taking extra caution."
Twitter says that it is sorry and will continue working to keep your data secure. If you have some questions, you can ask the company how it protects your personal data by filling out a Data Protection Inquiry Form. The iOS version of the Twitter app did not have a vulnerability which means that iPhone and iPad users will not be receiving any instructions from the firm.
