Micro-blogging social network Twitter on Friday urged all of its 330 million users to change their passwords after the discovery of a bug that caused some of the passwords to be stored in plain text on its internal computer system.

Twitter Inc added that the glitch had been fixed and that an internal investigation had found no indication that passwords were stolen or misused by insiders, but nonetheless advised users to change their passwords "out of an abundance of caution."

In a statement, Twitter support said, "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."

Twitter described the 'bug' on its blog:

"We mask passwords through a process called hashing using a function known as bcrypt, which replaces the actual password with a random set of numbers and letters that are stored in Twitter’s system. This allows our systems to validate your account credentials without revealing your password. This is an industry standard," Twitter said.

"Due to a bug, passwords were written to an internal log before completing the hashing process. We found this error ourselves, removed the passwords, and are implementing plans to prevent this bug from happening again," it added.

While Twitter did not specify how many passwords were affected, a person familiar with the company said to Reuters that the number was "substantial" and that they were exposed for "several months."

The person added that the bug was discovered by Twitter a few weeks ago and was reported to some regulators.
