The Critical Need for Web3 Penetration Testing

Recently, Bybit lost 1.4 billion USD due to front-end code hacking. This is just one of many devastating attacks on Web3 projects where vulnerable web interfaces and API services have led to massive fund losses. The increasing frequency and sophistication of these attacks demonstrates that comprehensive penetration testing is now more important than ever.

Real-World Consequences of Security Failures

Recently, Bybit lost 1.4 billion USD due to front-end code hacking. This catastrophic breach is just one example in a growing list of attacks targeting web3 projects where vulnerable web interfaces and API services have led to massive financial losses. These incidents highlight the critical need for robust security measures to protect against sophisticated attacks targeting application layers rather than the underlying blockchain technology itself. As the stakes continue to rise in the web3 ecosystem, comprehensive penetration testing has become not just recommended but absolutely essential for project survival.


Why Web3 Applications Need Specialized Penetration Testing

Web3 applications face unique security challenges that traditional penetration testing approaches often miss. Beyond standard web vulnerabilities, Web3 apps must secure connections between wallets and dApps, handle blockchain transactions securely, and protect sensitive cryptographic operations. Our specialized Web3 penetration testing methodology identifies these unique attack vectors across mobile apps, web interfaces, and API endpoints.


The Critical Importance of Red Team Exercises

For Web3 projects managing significant digital assets, traditional security testing isn't enough. Our Red Team operations simulate sophisticated attackers using combinations of social engineering, technical exploitation, and persistence techniques to test your entire security posture. These exercises reveal complex vulnerabilities and defense weaknesses that standard penetration tests might miss, providing a realistic assessment of your security against determined adversaries.


Why Not Do Security Crowd Testing?

Because the form-filling security crowd testing cannot guarantee the background of security researchers, web3 industry security is the core, there are too many cases of infernal affairs, as a professional independent industry top web3 security company, we must put an end to this, and cannot guarantee its professional ethics. We abide by this and must provide customers with 100% security, rather than doing some marketing gimmicks to reduce costs.
