Sony PlayStation Network (2011)

The Sony PlayStation Network suffered a catastrophic security breach in 2011, leading to a 23-day network outage and the compromise of approximately 77 million user accounts. This extensive downtime significantly damaged Sony's reputation and incurred estimated costs of $171 million for the company. The recovery period for the PlayStation Network was substantially longer than the average major breach recovery, exceeding it by over three weeks, demonstrating the complex and large-scale restoration efforts required. Furthermore, the financial repercussions of this incident were approximately 40% higher than typical rival estimates for similar large-scale data breaches, underscoring the severe economic consequences of inadequate cybersecurity measures within the gaming industry. The stolen data included usernames, passwords, and other personal information, with credit card data also compromised, though encrypted.
