Adobe Systems Inc said on Thursday it was the victim of sophisticated cyber attacks on its networks by hackers who accessed data belonging to millions of customers along with the source code to some of its popular software titles.

Chief Security Officer Brad Arkin said in a statement that the company believes the attackers accessed Adobe customer IDs and encrypted passwords and removed data relating to 2.9 million Adobe customers. That information includes customer names, encrypted payment card numbers, expiration dates and information relating to orders, he said.

He said they also accessed the source code for several Adobe software titles including Acrobat, ColdFusion and ColdFusion Builder.

It said it discovered the code while conducting an investigation into breaches at Dun & Bradstreet Corp , Altegrity Inc's Kroll Background America Inc and Reed Elsevier's LexisNexis Inc. Those attacks were disclosed on September 25.
