Why did "matscan" join my Minecraft server? (FAQ) ================================================= 2023-05-29T02:48:09.000Z matscan is a Minecraft bot that joins potentially vulnerable Minecraft servers and sends a message in chat to inform the admins. How should I secure my server? ============================== It should’ve told you in its long chat message but some servers might cut it off: * If the server was meant to be private then enable a whitelist. * If the server is offline-mode then enable online-mode in the server.properties or install a plugin such as [AuthMe](https://dev.bukkit.org/projects/authme-reloaded). * If the server has an exposed BungeeCord backend, firewall it, install [BungeeGuard](https://www.spigotmc.org/resources/bungeeguard.79601/), or switch to [Velocity](https://papermc.io/software/velocity). * Enable backups or install a plugin like [CoreProtect](https://www.spigotmc.org/resources/coreprotect.8631/). If you’ve done all of the above, then you’re probably fine. How did you find my server? =========================== I scan the internet for Minecraft servers, basically sending a packet to every IP address and seeing which ones respond (it’s a little more complex than this). Is your data public? ==================== No. You should still secure your server though since there are several griefing/harassment groups that use their own server scanners. Why did Herobrine try to join right before matscan? =================================================== matscan will try to join with the username Herobrine first, so if the server is offline-mode then it can demonstrate that people can join with any username. It may also use the username of a historical player if the server is offline-mode but has a whitelist. What IP does matscan join from? =============================== The bot will exclusively join from the IP address `151.115.73.107`. This page will be updated if it ever changes in the future. How can I contact you? ====================== My Matrix is [@mat:matdoes.dev](https://matrix.to/#/@mat:matdoes.dev) (preferred), but you might be able to find me on other social medias. How can I help? =============== If you appreciate the security work I do, please consider funding my projects at [ko-fi.com/matdoesdev](https://ko-fi.com/matdoesdev).
