Twitter says it has patched a vulnerability inside its Android app that could have potentially let malicious actors view information of private accounts and take over profiles through an intricate back-end process. If a hacker managed to exploit the loophole, they could send direct messages and tweets on the target account’s behalf.
The social network claims so far it hasn’t discovered any affected user, nor found evidence of whether a third-party service has taken advantage of the bug. However, Twitter is reaching out to the people whose details may have been exposed. It’s unclear how long the vulnerability was left out in the open. The issue is not present on Twitter’s iOS app.
Twitter is now rolling out an update to its Android app. So if you’re an Android user, you should head over to the Play Store and install it immediately irrespective of whether Twitter contacted you.
“We don’t have evidence that malicious code was inserted into the app or that this vulnerability was exploited, but we can’t be completely sure so we are taking extra caution. We have taken steps to fix this issue and are directly notifying people who could have been exposed to this vulnerability either through the Twitter app or by email with specific instructions to keep them safe,” the company said in a blog post.
Since the method for abusing the glitch wasn’t all that straightforward, it’s unlikely a lot of users have been impacted due to this. Twitter essentially left a sensitive storage area of its app unprotected. By either through another third-party app or an unverified online download, a hacker could, in theory, exploit that to insert a piece of malicious code into where Twitter stores your private information on your phone and misused that access to fetch your personal data as well as post messages and tweets from your profile.
This latest security flaw is, in a lot of ways, similar to the one that happened about a month ago. On November 25, Facebook and Twitter said private data of “hundreds of their users” was compromised through malicious third-party Android apps. The breach, the two social media companies claimed, was caused because there wasn’t sufficient isolation between various software developer kits within a single app on Android.
