Executive Summary
In December 2015, MCResolver - a tool used to resolve Minecraft usernames to IP addresses - had its backend database accessed, exposing about 13.1 million records. The data was limited to Minecraft usernames and IP addresses; no email addresses, passwords, or payment data were included.
ObscureIQ assessment: Risk is elevated because resolver-style tools can expose abuse-adjacent data useful for harassment, targeting, impersonation, or deanonymization inside gaming communities. This is not just a normal gaming-site breach. The service context suggests attacker or adversarial utility beyond ordinary credential exposure.
Breach Impact
The username-to-IP mapping supports network-level targeting (DDoS, IP-based tracking) of Minecraft players, but the absence of email/password limits credential-based risk.
