Which 2013 cyberattack compromised Adobe customer records and source code?

The Adobe data breach was the 2013 cyberattack that compromised Adobe customer records and source code.

Adobe disclosed in October 2013 that attackers had accessed information associated with millions of customer accounts and stolen source code for several products. The exposed account data included encrypted passwords and encrypted payment-card information, although the breach’s scale and details were revised as the investigation developed.

Security researchers also found source code for Adobe software, including portions connected with Acrobat and ColdFusion. The incident raised concerns that stolen source could help attackers study software weaknesses or reproduce cryptographic implementation mistakes.

This breach is distinct from the later Yahoo incident, which involved billions of accounts, and the Target breach, which primarily involved payment-card data collected at retail stores.
