"A list of nearly five million Gmail usernames and passwords have reportedly been published on a Russian online forum, but many of those accounts on the list have already been suspended or have old passwords. Still, millions of account credentials are out there, potentially posing a significant security risk for many.
When contacted by Russian media sources, Google representatives said that this list was in fact comprised of accounts collected over the years via phishing and hacking methods. In addition to Russian Gmail users, the list also contains accounts used by English and Spanish speaking owners. Google said this list was not created by someone who had compromised the company's services. However, it's still a wise idea for any Gmail user to regularly change their password just to be on the safe side."
"Google is responding by saying that its servers would have blocked suspicious log-in attempts. Noting that only 2 percent of the password and username combos would work, Google says it has protected affected accounts.
"We found that less than 2% of the username and password combinations might have worked, and our automated anti-hijacking systems would have blocked many of those login attempts," the search giant said. "We've protected the affected accounts and have required those users to reset their passwords."
Google said that if it notices anything unusual with your account, it would block sign-in attempts from devices and locations that are unfamiliar."
Might be worthwhile changing passwords for your Gmail accounts again folks...just incase!
