On Tuesday, approximately 5 million Google accounts and their passwords were leaked on the Russian Bitcoin Security forum btcsec.com. A forum user named tvskit created a topic
that included the leaked accounts and said that approximately 60% of the accounts were still valid. At this time, Google has not verified whether the leak is valid and there have been reports that this information is just a compilation of older leaks that go back a few years.
A password redacted version of the leaked file was then
in the /netsec/ subreddit, which can be used to determine if your account was in the leak. Numerous people in /netsec/ have confirmed that their accounts and the corresponding passwords were listed in the leak.
It is strongly suggested that you change your Google account password to be safe. If you use the same email and password at other sites, you should change it there as well.Edit: Reddit link has strike through.
