Version Summary:Additional information is available regarding the Adobe Systems Incorporated customer data and application source code data breach.
 

Description
 
Adobe Systems Incorporated reports that attackers accessed internal systems and accessed customer records, including credit card numbers and encrypted passwords. In addition, attackers accessed application source code. The breach was initially reported as affecting nearly 3 million customer records. Additional reports indicate that over 150 million customer records, including plaintext user password hints that may allow attackers to more easily recover passwords from the data, were lost in the incident.

Reports also indicate Adobe encrypted all the passwords with the same key and also used the ECB mode method for encryption, which renders encrypted data insecure. Reports also indicate that Adobe may have used the 3DES, which is a symmetric cipher, as the encryption algorithm, which could allow an attacker to gain access to all the passwords in the database if the decryption key is obtained.

Facebook has warned their customers that this breach may put their Facebook accounts at risk if using the same email and passwords from Adobe sites and have encouraged customers to answer additional security questions and change their passwords.

The data loss may impact Adobe customers. Attackers may use the information to conduct fraudulent financial transactions or attempt to use the recovered user information to access accounts on other services that Adobe customers may use. Users who have been impacted are advised to change their passwords on other web services to prevent the use of recovered credentials to compromise other services.

Source code recovered by attackers could be examined for weaknesses or security vulnerabilities. If attackers discover previously unknown or unpatched vulnerabilities, the attackers may attempt to exploit the vulnerabilities as part of secondary attacks. Adobe users are advised to apply any software updates as they become available.
