We recently posted about the Adobe breach that had compromised over 2.9 million user names, passwords and credit card numbers; well it seems that number was just a little shy, new reports are surfacing that indicate the number to be more like 150 million according to Naked Security.

A huge dump of the offending customer database was recently published online, weighing in at 4GB compressed, or just a shade under 10GB uncompressed, listing not just 38,000,000 breached records, but 150,000,000 of them.

As breaches go, you may very well see this one in the book of Guinness World Records next year, which would make it astonishing enough on its own.

The Verge explains that Adobe's initial estimate was that information on nearly 3 million user accounts was compromised during the intrusion. That number quickly ballooned up to 38 million. But according to Paul Ducklin at Naked Security, a database of Adobe user data has turned up online at a website frequented by cyber criminals. When all is said and done, Ducklin suggests Adobe's security blunder could rank among the worst in history. He says over 150 million "breached records" can be found in the database dump, which is a staggering 10GB when uncompressed.

For its part, Adobe is standing by its latest 38 million figure, and says that all impacted users have already been notified.
