A German online news site claims hundreds of email addreses belonging to “Minecraft” user have been leaked after a hack attack. However, Mojang, the popular game’s developer, has not publicly said anything concerning the leak allegations.

Heise, the abovementioned German online news outlet, claims around 1,800 email addresses and passwords belonging to “Minecraft” players were leaked. They do not provide any information as to when or how the leak happened but claim that the information is available now online in plain text and most of the affected players are German.

However, Mojang has remained mum on the issue. The company’s support website reports all services to be in good order. None of the developers involved in the game have commented on the problem on social media as well.

Web security analyst Graham Cluley posits there may have been different ways in which the information was leaked.

“Possibilities range from simple phishing attacks, keylogging malware stealing players’ details as they log into the game, or even a security breach at Minecraft itself,” he wrote. Cluley recommends those worried to change their passwords, especially if the same password is used in other accounts.

“You should be aware of the dangers that once criminals know you play ‘Minecraft’ and have your email address they could easily spam out attacks which use social engineering to trick you into clicking on dangerous links or open malicious attachments,” he warns.

Naked Security, a computer security blog run by security software developer Sophos, argues Mojang has not mentioned the potential leak because it may happen more often than thought. The number of people exposed is minimal when compared to the 100 million players who use “Minecraft.” However, “what people are really worried about is that this small leak might be part of a much larger cache of credentials stolen in an Adobe-style break-in of the ‘Minecraft’ network.”

Having a “Minecraft”-related email address can allow one to download the game, which costs $27.

On other news, Nathan Adams, one of Mojang’s developers, hinted at working on the new 1.9 update for “Minecraft” on Twitter.
