In 2012, Adobe reported that a hack had compromised about 40 million sets of payment-card information. The following year, the breach expanded into a deeper corporate-security crisis: attackers stole substantial portions of Adobe’s software source code, and more than 150 million customer records were reportedly made available for download. The exposed material included encrypted customer information and data associated with Adobe accounts, while the stolen code created additional risks for users of the company’s products.
The source does not identify the attackers or name an internal whistleblower, and it does not describe a criminal conviction or a definitive finding that Adobe executives intentionally concealed the intrusion. The incident nevertheless demonstrated the consequences of concentrating payment, account, and proprietary software data inside one major technology provider. It became one of the most consequential security failures in Adobe’s history, prompting continuing scrutiny of the company’s security practices and the protection of customer information.
