Encrypted data including customers' names, passwords and credit card numbers was stolen

Multinational software giant Adobe has revealed that information related to 2.9 million of its customers was stolen from it during a “sophisticated” hack.

Details of the attacks were posted on the company’s blog by chief security officer Brad Arkin.

“Our investigation currently indicates that the attackers accessed Adobe customer IDs and encrypted passwords on our systems,” wrote Arkin.

“We also believe the attackers removed from our systems certain information relating to 2.9 million Adobe customers, including customer names, encrypted credit or debit card numbers, expiration dates, and other information relating to customer orders.”

Arkin stressed that no decrypted financial information was stolen, but that the company will contact all those users whose information was involved. These individuals will also be offered the option of enrolling in “one-year complimentary credit monitoring membership where available.”

As well as user information the hackers also targeted the company’s products, with Arkin stating that Adobe was “investigating the illegal access to source code of numerous Adobe products”.

“We value the trust of our customers,” said the statement. “We will work aggressively to prevent these types of events from occurring in the future. Again, we deeply regret any inconvenience this may cause you.”
