MCResolver Breach

MCResolver was a significant data breach that exposed over 13 million rows of data around the end of 2014. The incident involved an IP resolver service widely used within the Minecraft community, which inadvertently returned sensitive information—specifically, the usernames and corresponding IP addresses of players. This vulnerability allowed unauthorized access to real-world connection details, thereby creating serious privacy risks and opening the door for potential targeted attacks, such as distributed denial-of-service (DDoS) assaults.
