Incidents from
In July 2007, the multiplayer game portal known as gPotato (link to archive of the site at that time) suffered a data breach and over 2 million user accounts were exposed. The site later merged into the Webzen portal where the original accounts still exist today.
A three-week wave of distributed denial-of-service attacks crippled Estonian government, banking, and media websites amid a dispute with Russia, becoming the first cyber assault on an entire nation-state and the birthplace of NATO's cyber-defence doctrine.
Attackers led by Albert Gonzalez sniffed weakly-encrypted in-store Wi-Fi at a Marshalls outlet and pivoted to TJX's central systems, exfiltrating an estimated 94 million payment-card records over an 18-month intrusion — the largest U.S. retail data breach of its era.
