Overview: What are booters and stressers?
In the gaming community, booters and stressers refer to illegal DDoS-for-hire services used to knock opponents offline. For a low fee, an attacker can hire a Botnet—a collection of thousands of compromised devices—to flood your home IP address with large amounts of unwanted traffic (typically a UDP flood). This saturates your bandwidth and overwhelms your router, causing lag spikes, disconnects, or temporary loss of connectivity during a match.
How Attackers 'Pull' Your IP Address
Before launching an attack, the attacker must first identify your IP address. They achieve this through several 'IP Pulling' methods:
- Peer-to-Peer (P2P) Lobbies: Older games and some modern voice chats (like TeamSpeak) connect players directly. An attacker running a packet sniffer can see the IP of everyone in the lobby instantly.
- IP Loggers (tracking links): An attacker sends a link (e.g., to a meme or a 'tournament bracket') that records your IP the moment you click it.
- Party Chats: Joining a stranger's party or voice server can expose your IP address to other users in the session.
- Bait Links: Using tracking links to log your connection details.
Technical Attack Vectors: UDP Floods
Most booters exploit the UDP Protocol because it doesn't require a 'handshake.' The botnet floods your connection with millions of spoofed UDP packets targeting your router's open ports, saturating your bandwidth and overwhelming its connection-tracking table. Your router tries to process every single one, eventually becoming overloaded by the volume of traffic. Some services also use Amplification Attacks, where they trick public servers (like DNS or NTP) into sending massive amounts of data to your IP, amplifying the attack volume hundreds or even thousands of times.
DDoS Protection Comparison
| Method | Protects Against IP Exposure | Protects Against Flood Traffic | Notes |
|---|---|---|---|
| VPN | Yes | Partial | Hides home IP from peers |
| Dedicated Game Servers | Yes | Yes | Peers never see your IP directly |
| Router Firewall | Partial | Partial | Helps against smaller, un-amplified attacks |
| ISP IP Change | Partial | No | Only useful after an attack has ended |
| UPnP Disabled | Partial | No | Reduces exposed services and vulnerability |
Router and Firewall Protection
Disable UPnP if you do not need it, avoid exposing gaming devices directly to the internet, and make sure your router firmware is updated regularly. Some routers also include flood detection, rate limiting, and basic DDoS filtering options. Using a stricter NAT type can reduce the number of services exposed to external scanners, although it may affect matchmaking or voice chat in some games.
How Modern Games Reduce IP Exposure
Modern games such as Fortnite, Valorant, and Call of Duty increasingly use dedicated servers, relays, and centralized voice chat services. This reduces the chance that players can see each other's IP addresses directly, as all traffic is routed through the publisher's high-capacity infrastructure instead of peer-to-peer (P2P).
When to Contact Your ISP
If attacks continue after changing your IP address, contact your ISP and ask whether they offer DDoS filtering, modem replacement, or static IP reassignment. Some providers can also move customers to a different IP range if repeated attacks occur.
Mitigation and Recovery Strategies
- Use a Gaming VPN: This is the most effective defense. A VPN hides your home IP. If a player attacks 'you,' they are only hitting the VPN server, which handles the load via robust DDoS mitigation systems.
- Power Cycle Your Modem: If you are under attack, unplug your modem for 30 minutes. This often forces your ISP to assign you a new dynamic IP address, making the previous target address unusable.
- Monitor Your Logs: If your connection fails, check your router's admin page for 'UDP Flood Detected' logs. This may indicate that your connection is experiencing a flood attack.
