Today, almost five million email addresses and passwords were posted on Bitcoin Security, a Russian forum. The forum member who posted the various Gmail and Yandex accounts, "tvskit," claims that 60 percent of the passwords are valid. However, some of them are outdated—the password shown for my personal email address was changed months ago and Business Insider notes that some were as outdated as ten years.

Though the forum manager has already removed the file containing exactly 4,930,000 emails and passwords, it has led to somewhat of a digital panic as people work to learn if they have been affected. Someone has created the website "isleaked.com" (isleaked.com/en.php for the English version) for users to match their email address against the list to see if they were affected:

The one silver lining to this incident: It looks like these emails weren't from a new hack, instead, they were compiled from a bunch of old thefts.
