News update, 13/09/2014

From what has been gathered so far, it appears as if this is not a new hack, and that the list may have been created from different sources. Google has posted an official response. According to the company, the data dump was not the result of a security breach.

Today's big news is the release of a database with more than 5 million Gmail email account user information. The database appears to include usernames, passwords and email addresses of users and while it has not been confirmed as legitimate yet by third parties it has been made available publicly on the Internet.

It is for instance possible to download all leaked email addresses from the file hosting service Mega. While you will only find email addresses listed in the 100 Megabyte text document, it is enough to verify if your own Gmail email address is affected by the leak.

Downloading the email address and searching for your own email is probably the best option that you have to find out if you are affected. If you don't want to download the packed 36 Megabyte file to find out, you can also use third-party services such as Is Leaked on the Internet.
