What happened in Have I Been Pwned’s words
In March 2017, the Flash game based on the Yu-Gi-Oh trading card game Dueling Network suffered a data breach. The site itself was taken offline in 2016 due to a cease-and-desist order but the forum remained online for another year. The data breach exposed usernames, IP and email addresses and passwords stored as MD5 hashes.
