Our investigation currently indicates that the attackers accessed Adobe customer IDs and encrypted passwords on our systems. 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. At this time, we do not believe the attackers removed decrypted credit or debit card numbers from our systems.If Adobe believes that you were a victim of the attacks, the company will be contacting you and will advise that you change your passwords, as well as provide precautionary steps that should be taken by those who may have had their debit or credit card information compromised. Adobe has notified banks of the incident to further help prevent any fraudulent activity from occurring. The company is also investigating whether or not source code for Adobe products were accessed.
Regardless of if you are contacted by Adobe in regards to the infiltration, it would probably be best to update your Adobe ID security information as soon as possible.
