Twitter on Saturday admitted a malicious code was inserted into its app by a bad actor that may have compromised some users’ information worldwide, including in India, as people woke up to an email from Twitter, warning them to update the app for Android.
The vulnerability within Twitter for Android could allow the bad actor to see non-public account information or to control your account (send Tweets or Direct Messages), said an apologetic Twitter.
“Prior to the fix, through a complicated process involving the insertion of malicious code into restricted storage areas of the Twitter app, it may have been possible for a bad actor to access information (Direct Messages, protected Tweets, location information) from the app,” Twitter said in a statement.
The company said it does not have direct evidence that malicious code was inserted into the app or that this vulnerability was exploited, but it can’t be completely sure. Twitter did not divulge the number of users affected too.
“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”.
Twitter recommended updating to the latest version for Android as the issue did not impact “Twitter for iOS”.
“We’re sorry this happened and will continue working to keep your information secure on Twitter,” said the company in the email sent to the Indian users, adding that those affected can also reach out to Twitter’s Office of Data Protection, requesting information regarding their account security.
Twitter has faced several vulnerabilities on its platform in the recent past.
In May, Twitter disclosed a bug that shared some iOS users’ data with an unnamed partner, even if the users did not opt to share data. The bug affected Twitter’s iOS user base and they were notified about the issue.
In February, a bug in Twitter exposed private tweets of some Android users for over five years when they made changes in their settings, like changing the email address linked to their accounts.
