Heise Online reported the hack and a large number of the verified accounts (selection shown) are believed to be belonging to German gamers. Although it's not clear how the hackers obtained the credentials, security analyst Graham Cluely stated that there are many possibilities. This includes phishing attacks and malware as well as security breaches. Heise Online reported the hack and many of the verified accounts are believed to be belonging to German gamers.

Cybercriminals can also get access to an individual's email address to hack other accounts and send malware or even send spam.

While the amount of information revealed is not that big when compared to the game's 100,000,000,000 players and players, Mr. Cluely said that there's no guarantee that the hacker that published the list of details didn't have more information 'in their back pockets'.
