These assaults aren't just the work of rogue hackers; sometimes, they are carried out by organized griefing groups using auto-griefing bots that exploit unprotected "cracked" (offline-mode) servers. These groups scan for servers, impersonate operators, and use destructive commands to erase entire worlds, often targeting small communities and individual players.
A Java-based bot tool designed to test how your server handles multiple concurrent connections.
Even behind a proxy, basic rate limiting is a must. You can use iptables / nftables on Linux to limit new connection attempts from a single IP, which is excellent for stopping low-and-slow attacks at a kernel level.
can detect if a player is moving too perfectly (like a bot) and kick them automatically. FlameCord:
A Minecraft bot attack occurs when an attacker uses automated software to connect massive numbers of simulated clients to a specific server IP address.

This comprehensive guide will walk you through everything you need to know to protect your Minecraft server from bot attacks for free.
