Some 48 million Gmail usernames and passwords have been leaked in a criminal database.

The full database contains 149 million compromised credentials, including 17 million Facebook accounts, 6.5 million Instagram accounts, and 4 million Yahoo usernames and passwords.

It was publicly available for one whole month before security researcher Jeremiah Fowler was able to get it taken down.
