If you're on the social networking site Twitter, now may be a very good time to log in and change your password. It was announced yesterday that tens of thousands of Twitter usernames and passwords were leaked and posted publicly on the internet.

Twitter has launched an investigation into the security breach. "We are currently looking into the situation," explained Twitter spokesman Robert Weeks. "In the meantime, we have pushed out password resets to accounts that may have been affected."

A number of the leaked passwords belong to spam accounts, and it appears some of the accounts may be duplicates. Surprisingly, many of the passwords which were hacked are considered to be "strong" seemingly random strings of numerals, upper case, and lower case letters. It is unknown how the passwords were discovered, just that that the data first appeared online on Monday.
