Twitter asks users to change passwords after bug exposed them on internal log
Twitter today asked all of its users to consider changing their passwords after discovering a bug that caused them to be stored "unmasked in an internal log."
According to Twitter, the bug has been corrected and it has seen "no indication of breach or misuse by anyone" after an investigation.
We recently found a bug that stored passwords unmasked in an internal log. We fixed the bug and have no indication of a breach or misuse by anyone. As a precaution, consider changing your password on all services where you've used this password. https://t.co/RyEDvQOTaZWe recently found a bug that stored passwords unmasked in an internal log.

The bug itself is related to the hashing function Twitter uses to mask passwords. Twitter says passwords were written to an internal log before the hashing process was completed, leaving them exposed. From Twitter:
Out of caution, Twitter users should reset their password for the service, as well as those for any services using the same password. Now would also be a good time to start using two-factor authentication if you aren't already.
