Crafting Shields: Defending Minecraft Servers Against DDoS Attacks. Minecraft, with over 500 million registered users and 166 million monthly players, faces significant risks from distributed denial-of-service (DDoS) attacks, threatening server functionality, player experience, and the game's reputation. Despite the prevalence of DDoS attacks on the game, the majority of incidents go unreported, leaving a gap in awareness and protection. This article explains what happens to a Minecraft server during a DDoS attack and how to protect against such attacks. For an in-depth version of the article, check out this white paper. When Creepers Breach: What Happens When an Attack Is Successful When a Minecraft server is hit with a DDoS attack, players may have problems with logging in to servers, loading worlds, navigating biomes, using tools, and chatting. They can also experience general lags, disconnections, timeouts, or server crashes. These in-game disruptions can ruin the gaming experience for players while causing financial and reputational losses to server owners, operators, and the wider Minecraft community. What Happens to a Minecraft Server During a DDoS Attack? In a DDoS attack, the attacker's objective is to disrupt a Minecraft server, rendering it unstable or unavailable to legitimate users, by flooding it with malicious traffic until it becomes overwhelmed. DDoS attacks on Minecraft servers can last anywhere from a few seconds to days, depending on their severity and the countermeasures in place. Severe attacks can cost players prize money in tournaments, diminish players' confidence in the server, cause server crashes, or even force servers to be upgraded for better redundancy and resilience against future attacks. Evidence of an Attack This checklist serves as a handy reference guide when facing suspicious network activities that resemble DDoS attacks. If several of these signs converge at any given time for your Minecraft server, there's a high probability that a DDoS attack is underway and requires immediate remediation. If you're not sure whether an attack is occurring, contact your ISP or host. They should be able to verify whether it's a DDoS attack or not. In some cases, these signs could be symptoms of other cyberattacks or unrelated network issues, and will thus yield false positive results. Impact on Minecraft Servers and the Minecraft Community DDoS attacks significantly affect Minecraft servers, players, server owners, and the entire community. Disruption of gameplay isn't the only concern. An attack leading to a player missing out on significant tournament earnings, has, in extreme cases, resulted in tragic outcomes with profound emotional impacts, rippling through the community and reaching friends and family. This emphasizes the need for robust protection and awareness. DDoS attacks on Minecraft servers can have numerous impacts: Examples of Recent Attacks Most Minecraft server DDoS attacks never make it to the news. A lot of small-scale attacks hit personal or private servers for the reasons discussed above. However, larger-scale DDoS attacks are more likely to create press because of their value as a marketing strategy for DDoS protection providers or because of the real-life consequences that result from the attack. The largest ever Minecraft DDoS attack targeted the popular Wynncraft Minecraft server in 2022. A Mirai botnet variant launched a two-minute long 2.5 Tbps attack using UDP and TCP flood packets to attack the server, aiming to disrupt gameplay for hundreds of thousands of players. Massive attacks on this scale—and the many more attacks on private and smaller servers that attract less attention—highlight the need to be wary of Minecraft DDoS attacks. It is therefore essential for server owners, admins, engineers, and hosting providers to protect their servers and the users who rely on them. Let's explore some methods for DDoS mitigation. Obsidian Walls: How to Protect Minecraft Servers Against DDoS Attacks Basic Protective Measures To defend your Minecraft server against DDoS attacks, begin with basic security measures: It's important to stay current on the latest DDoS tactics, signs, and countermeasures, and ensure server moderators are also well-informed.
