CW3H Certification in Credential

Certification Overview

The Certified Web3 Hacker (CW3H) Certification is a specialized credential aimed at equipping professionals with the knowledge and skills required to address the unique security challenges of Web3 technologies, including blockchain, smart contracts, and decentralized finance (DeFi). Below is an explanation of its key components:

1. Web3 Security Fundamentals

This module introduces the foundational concepts of Web3, including blockchain architecture, smart contracts, and decentralized applications (dApps). It highlights common vulnerabilities such as protocol-level risks, phishing attacks, and private key theft.

2. Getting Started with Web3 Hacking

This section focuses on the basics of ethical hacking in the Web3 ecosystem. It emphasizes identifying vulnerabilities in blockchain-based systems and preparing for advanced modules like exploit development.

3. EVM Security

This module addresses security risks specific to the Ethereum Virtual Machine (EVM), including:

  • Access Control Issues: Improper privilege management can lead to unauthorized actions.
  • Delegatecall Exploits: Misuse of delegatecall can allow attackers to execute malicious code.
  • Frontrunning: Exploiting transaction ordering for financial gain.
  • Reentrancy Attacks: Manipulating contract states through recursive calls.
  • Unchecked Returned Values: Ignoring error codes can lead to vulnerabilities.

4. Token Security

It covers threats related to token contracts, such as:

  • Fake Tokens: Fraudulent tokens used for scams.
  • Malicious Tokens: Tokens designed to exploit wallets or dApps.
  • Missing Zero Address Checks: Allowing transactions to invalid addresses.
  • Unconstrained Token Supplies: Lack of supply limits leading to inflation or exploitation.

5. DeFi Security

This module explores vulnerabilities in decentralized finance systems:

  • Centralized Control Risks: Admin keys or centralized components being compromised.
  • Frontend Vulnerabilities: Exploiting user interfaces for phishing or data theft.
  • Governance Abuse: Manipulating governance mechanisms for malicious purposes.
  • Price Manipulation: Using oracle exploits or flash loans to distort market prices.

6. Developing Exploits

The final module teaches students how to simulate attacks ethically by:

  • Writing exploit contracts.
  • Testing exploit code in controlled environments.
  • Identifying and resolving vulnerabilities through practical exercises.

Benefits of the Certification

  1. Comprehensive Skill Development: Covers theoretical knowledge and hands-on practice for real-world applications.
  2. Career Advancement: Prepares professionals for roles like Web3 Security Engineer or Smart Contract Auditor.
  3. Future-Proof Expertise: Addresses emerging security needs as Web3 adoption grows globally.
