Services restored after 23 days of downtime, with compensation offered to PSN users
Personal data exposed for 77 million PlayStation Network accounts
$171 million in costs for Sony
The 2011 PlayStation Network outage (sometimes referred to as the PSN Hack) was the result of an "external intrusion" on Sony's PlayStation Network and Qriocity services, in which personal details from approximately 77 million accounts were compromised and prevented users of PlayStation 3 and PlayStation Portable consoles from accessing the service.[1][2][3][4] The attack occurred between April 17 and April 19, 2011,[1] forcing Sony to deactivate the PlayStation Network servers on April 20. The outage lasted 23 days.[5]
Government officials in various countries voiced concern over the theft and Sony's one-week delay before warning its users. The breach resulted in the exposure and vulnerability of personally identifiable information including usernames, physical addresses, email addresses, dates of birth, passwords, and financial details such as credit card and debit card information.[6]
