As a website owner, you know how important it is to protect your site from bots that can harm your business. Bots can scrape your content, spam your forms, and even launch DDoS attacks. Traditional techniques such as CAPTCHAs and rate limiting can be effective, but they can also be intrusive for your users. In this post, we'll explore a new approach using WebAssembly that can help you protect your site from bots while keeping your user experience smooth and seamless.
What is WebAssembly ?
WebAssembly (WASM) is a low-level virtual machine that runs code in a sandboxed environment, similar to a browser. It's designed to be fast, efficient, and portable, and can run on any platform that supports it, including browsers, servers, and IoT devices. WASM code is typically written in languages such as C++, Rust, or Go, and compiled into a binary format that can be executed by the runtime.
How can WebAssembly protect your site from bots?
WebAssembly can be used to implement anti-bot measures in your website's client-side or server-side code. For example, you can write a WASM module that checks if a user is human by analyzing their mouse movements, keystrokes, or other behavioral patterns. This can be done without requiring the user to solve a CAPTCHA or perform any other intrusive action. If the module detects bot-like behavior, it can block the request or challenge the user with a non-intrusive test.
Examples of WebAssembly anti-bot solutions
There are already several open-source projects that use WebAssembly to protect websites from bots. Here are some examples:
How to get started with WebAssembly anti-bot measures
If you're interested in using WebAssembly to protect your site from bots, here are some steps you can follow:
One of the benefits of using WebAssembly for anti-bot measures is that it can be difficult for attackers to reverse engineer. Unlike JavaScript, which can be easily inspected and modified by anyone who has access to the browser console, WebAssembly code is compiled into a binary format that's not human-readable. This makes it harder for attackers to understand the logic of the anti-bot measures and bypass them.
Moreover, WebAssembly code can be obfuscated to make it even more challenging to reverse engineer. Obfuscation techniques such as code splitting, control flow flattening, and dead code insertion can be applied to WebAssembly modules to make them less predictable and harder to analyze. This can deter attackers who are looking for easy targets and force them to spend more time and resources on attacking your site.
Of course, no anti-bot measure is foolproof, and determined attackers can still find ways to bypass WebAssembly-based protection. However, by using WebAssembly, you can raise the bar for attackers and make it more difficult for them to succeed. Additionally, as WebAssembly becomes more prevalent, tools for analyzing and manipulating it are likely to improve, making it even more challenging for attackers to reverse engineer.
Conclusion
WebAssembly is a powerful tool that can help you protect your website from bots in a fast, efficient, and non-intrusive way. By using WASM-based anti-bot measures, you can improve your site's security and user experience, and attract more customers to your business. Additionally, WebAssembly code can be difficult to reverse engineer, making it a formidable barrier for attackers who want to bypass your anti-bot measures. However, no anti-bot measure is completely foolproof, and it's always a good idea to keep an eye on emerging threats and adapt your defenses accordingly. With WebAssembly, you can stay one step ahead of the bots and keep your site secure for your users.

There are already several open-source projects that use WebAssembly to protect websites from bots. Here are some examples:
- WASMcaptcha: a WASM-based CAPTCHA that analyzes user behavior to distinguish humans from bots. It's lightweight, customizable, and easy to integrate into any website.
- Botd: a server-side solution that uses WebAssembly to detect and block malicious bots in real-time. It's highly performant and can handle millions of requests per second.
- PerimeterX: a cloud-based platform that uses WebAssembly to provide advanced bot protection, including device fingerprinting, behavioral analysis, and threat intelligence.
How to get started with WebAssembly anti-bot measures
If you're interested in using WebAssembly to protect your site from bots, here are some steps you can follow:
- Learn the basics of WebAssembly and how to write and compile WASM modules.
- Identify the types of bots that are attacking your site and the anti-bot measures you want to implement.
- Choose a WebAssembly framework or library that fits your needs and integrate it into your website's code.
- Test your anti-bot measures thoroughly to ensure they're effective and non-intrusive for your users.
