A data breach is an incident where private and confidential information is released to untrusted environment without authorization from its owners. It is usually done by hackers who constantly exploiting weaknesses in corporate networks to copy, transmit and steal sensitive data. This data might include someone’s personal information like medical records, bank accounts, credit card accounts, e-mail accounts and intellectual properties.
Data breach can affect many user accounts. One example is the 2013 Adobe data breach where 2.9 million customer accounts from Adobe were hacked. The attackers accessed Adobe customer IDs and encrypted passwords.
This include customer names, credit card numbers, expiry dates and other information relating to customer orders. Additionally, attackers also accessed source codes of numerous Adobe products.
