The recent data breach at Adobe that exposed user account information and prompted a flurry of password reset emails impacted at least 38 million users, the company now says. It also appears that the already massive source code leak at Adobe is broadening to include the company’s Photoshop family of graphical design products.

In a breach first announced on this blog Oct. 3, 2013, Adobe said hackers had stolen nearly 3 million encrypted customer credit card records, as well as login data for an undetermined number of Adobe user accounts.
At time time, a massive trove of stolen Adobe account data viewed by KrebsOnSecurity indicated that — in addition to the credit card records – tens of millions of user accounts across various Adobe online properties may have been compromised in the break-in. It was difficult to fully examine many of the files on the hackers’ server that housed the stolen source because many of the directories were password protected, and Adobe was reluctant to speculate on the number of users potentially impacted.
But just this past weekend, AnonNews.org posted a huge file called “users.tar.gz” that appears to include more than 150 million username and hashed password pairs taken from Adobe. The 3.8 GB file looks to be the same one Hold Security CTO Alex Holden and I found on the server with the other data stolen from Adobe.
Adobe spokesperson Heather Edell said the company has just completed a campaign to contact all existing users whose login and encrypted password information was stolen, urging those users to reset their passwords. She said Adobe has no indication that there has been any unauthorized activity on any Adobe ID involved in the incident.
“So far, our investigation has confirmed that the attackers obtained access to Adobe IDs and (what were at the time valid), encrypted passwords for approximately 38 million active users,” Edell said [emphasis added]. “We have completed email notification of these users. We also have reset the passwords for all Adobe IDs with valid, encrypted passwords that we believe were involved in the incident—regardless of whether those users are active or not.”
Edell said Adobe believes that the attackers also obtained access to many invalid Adobe IDs, inactive Adobe IDs, Adobe IDs with invalid encrypted passwords, and test account data. “We are still in the process of investigating the number of inactive, invalid and test accounts involved in the incident,” she wrote in an email. “Our notification to inactive users is ongoing.”
