5M Google Accounts Hacked, Leaked on Russian Bitcoin Forum

No Google Account has been hacked. They're just aggregated leaks from random compromised websites.

If you don't re-use passwords, no action needs to be taken.

From your first link, this seems worth calling out specifically: "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. We’ve protected the affected accounts and have required those users to reset their passwords."

Any word on what site(s) were hacked leading to this leak? I don't reuse any passwords so I'm not very concerned, but I'm the kind of person who just likes to be sure
