Adobe reveals customer data stolen in security breach 3 October 2013 Last updated at 22:12 Adobe has warned that 2.9 million customers might have had their information stolen during a cyber attack on the company's website. Stolen information includes customer names, encrypted credit or debit card numbers, and expiration dates. Adobe said it believes that the attackers did not remove decrypted debit or credit card information. "We deeply regret that this incident occurred," said the company in a statement on its website. Hackers might have had access to credit information after stealing user IDs and encrypted passwords. Adobe said that it is resetting passwords for the customer accounts it believes was compromised, and that those customers will get an email alerting them to the change. It is also recommending that customers affected change their passwords and user information for other websites for which they used the same ID as a precaution. For those customers whose debit or credit card information is suspected of being compromised, Adobe is offering a complimentary one-year subscription to a credit-monitoring programme. Finally, the company said it had notified law enforcement officials and is working to identify the identity of the hackers. Adobe said that has noticed an uptick in cyber attacks recently, noting that attacks have now become one of the "unfortunate realities of doing business today." It also said that the source code of numerous Adobe products may have been compromised.
