More than 18 million players may have been affected by a suspected data breach involving the game Minecraft. With over 425 million copies sold worldwide across multiple platforms, Minecraft is the most popular video game globally. According to Cybernews, the breach involves information potentially affecting more than 18 million users, based on claims made on a specialized forum on the dark web. One claim stated that 18 million users' data had been stolen, while another offered data from at least 9 million users. The data includes usernames, emails, and encrypted passwords, which could be used for denial of service attacks or phishing operations. Some passwords, once decrypted, could allow access to other platforms if the same combinations are used, such as on cryptocurrency sites or social networks. The data samples viewed by Cybernews suggest that the two databases offered on the dark web contain the same information, although this has not been confirmed. Mojang, the studio behind Minecraft, has not commented on the issue, but BFM Tech contacted Microsoft (which owns Mojang) for more information. According to Cybernews, the breach may be linked to several malicious software programs distributed on platforms such as GitHub, with suspected Russian origins. A 2025 study by Check Point Research found at least 1,500 devices compromised by this type of software. These programs often promise features like cheating or automating actions, which are popular within the modding community. Until an official statement is made, users are advised to check if their computers are infected, particularly with software such as Malwarebytes. It is strongly recommended to change passwords and use a password manager to create unique and difficult-to-find passwords for each site or platform. The dark web is a part of the internet that is not indexed by standard search engines and is often used for illicit activities, making it a common place for stolen data to be sold or shared. Users are encouraged to remain vigilant and take proactive steps to secure their personal information.
