Earlier today, news started making the rounds that a list of 5 million Gmail addresses and passwords was leaked on Tuesday, Sept 9 2014.
The list appeared on a Russian Bitcoin forum site and after some review, appears to be the result of a number of years of hacking and phishing campaigns as opposed to a direct assault on the Google mothership.
Some of the accounts also appeared to be quite old, and in some cases the gmail address appeared to be the username for another online account.
So what we are probably seeing is actually some hacker’s private stash rather than someone looking for help in cracking a password database.
