The Death of the IP Ban
In the early 2010s, if you were caught using an aimbot in Minecraft or Counter-Strike Source, the server administrator would execute a simple IP Ban. Your public IP address was blacklisted entirely.
Hackers quickly learned how useless this was. Because most ISPs use "Dynamic IPs", a cheater simply had to unplug their home router for 10 minutes to be assigned a brand new IP address, completely bypassing the ban. Alternatively, a cheap VPN solved the problem instantly.
The Era of Kernel-Level Security
Riot Games (Valorant) and Activision (Call of Duty) realized network bans were dead. They engineered a terrifying solution: Kernel-Level Anti-Cheats, specifically Riot Vanguard and CoD Ricochet.
These security systems operate at "Ring 0", the deepest, most privileged level of your operating system. They boot up before Windows even fully loads. Their goal is no longer to track your network connection; their goal is to identify your physical hardware. This is the HWID (Hardware ID) Ban.
How an HWID Ban Ruins Your Computer
When Vanguard detects cheat software injecting code into the game memory, it doesn't just ban your account. It takes a permanent snapshot of your PC's physical components:
- The serial number of your Motherboard.
- The MAC address of your Network Interface Card.
- The unique descriptors of your primary SSD/Hard Drive.
- The identifiers of your RAM sticks and Processor.
The Anti-Cheat combines these serial numbers into an encrypted cryptographic hash. Your physical PC is now blacklisted.
You can create 100 new accounts. You can use the most expensive proxies in the world. You can format Windows entirely. But the second you try to launch Valorant, Vanguard reads your motherboard's serial number, sees the blacklist, and instantly bans the new account.
The Desperate Counter-Measures: HWID Spoofers
The cheat industry responded by selling "HWID Spoofers." These are highly illegal, malware-like programs that operate at the Kernel level to purposefully feed fake serial numbers (spoofed data) to the Anti-Cheat drivers.
However, this is an escalating arms race. Vanguard frequently updates to detect when a Spoofer is running, resulting in mass "Ban Waves" that brick thousands of cheating PCs simultaneously. In modern eSports titles, getting caught cheating often means you literally have to buy a new $1,500 PC to ever play the game again.
