A hacker has stolen Attack.Databreach millions of accounts from Dueling Network , a now-defunct Flash game based on the Yu-Gi-Oh trading card game . Although Dueling Network itself shut down in 2016 in response to a cease-and-desist order , the site 's forum continued running until recently . The message currently displayed on the Dueling Network forum . `` Only our forum site was still up as a way for our users to communicate with each other ( login used DN [ Dueling Network ] credentials ) . Now that is down and warns users to change passwords on any other sites they may have used the same password on , '' Black Luster Soldier , a Dueling Network administrator , told Motherboard in an email .

Note that many accounts are duplicates owned by the same user or were never actually logged in , so this number is inflated , '' they said . The data includes user email addresses and passwords hashed with the notoriously weak MD5 algorithm , meaning hackers will likely be able to obtain Attack.Databreach a number of users ' plaintext passwords as well . Paid breach notification service LeakBase provided Motherboard with a small sample of accounts for verification purposes .

The lesson : As Black Luster Soldier advised , users should change their passwords on any other services with the same credentials as Dueling Network . Even if data from the breached site is n't all that valuable in and of itself , if someone has used the same password on another site , hackers can easily try to access other more serious accounts too
