Why does this breach matter?
In-depth analysis of the breach and its implications.
In March 2017, a data breach involving Dueling Network, an online Flash-based game modeled after the Yu-Gi-Oh trading card game, disclosed 6,486,626 records. The compromised database included usernames, email addresses, IP addresses, and passwords hashed with MD5—a method considered cryptographically weak. While the game itself was terminated in 2016 following a legal order, its forum remained active and was likely the source of the breach.
