Yes, it’s that time again — password changing time. On Thursday, Twitter revealed that a bug caused the platform to store user passwords in unmasked form. Normally, sensitive personal data like passwords would be stored in hashed form using a mix of letters and numbers to protect the content of the password itself. In this instance, it sounds like Twitter stored plain text passwords openly without any hashing on an internal log.
Twitter notes that it currently has “no reason to believe password information ever left Twitter’s system” or that these unprotected passwords were accessed by hackers, but the risk of the unknown remains. The company has advised users to change their passwords as a precautionary measure.
Here’s what Twitter says happened:
We’ve reached out to Twitter for more details on the bug and additional information about how this could have happened. Update: Twitter declined to provide additional technical details on the incident but emphasized that is believes the likelihood that the passwords were discoverable is “extremely low” and an internal investigation has revealed no indications of a breach or other misuse.
