You may have read that nearly 5 million usernames and passwords associated with Gmail accounts have been leaked on a Russian Bitcoin forum yesterday.
There’s no evidence that Gmail itself was hacked—just that these passwords have been leaked. Most sources claim these passwords are old, so chances are they were leaked long ago—though others are claiming 60% of the passwords are still valid.
Though the list itself has been removed from most sites like KnowEm LLC have made the hacked list of emails publicly searchable. You can visit the page, enter your address and we’ll let you know if you’re on the list of possible compromised accounts.

One2One’s always recommends changing your password to a strong one and updating it periodically to prevent these types of issues from affecting you.
