Renewed CTF with recent exploits and attacks
Smart Contracts are getting more and more interest from the security community, driven mostly by the big payout for smart contract security auditing and the continuous exploitation of vulnerabilities in smart contracts, web3 and DeFi applications. The financial implications of smart contract vulnerabilities are substantial. Smart contracts often handle large amounts of value, and successful exploitation can lead to significant financial losses for users and project developers. With the increased regulatory scrutiny on blockchain and cryptocurrency projects, security audits and compliance with industry standards become imperative.

 

Some of the scenarios we will go through:

– Any user can cash out the money from the smart contract
– Abuse business logic to pay with 0 ETH
– Reentrancy vulnerabilities
– Block Timestamp Manipulation Vulnerability
– Tx.origin: Authorization bypass.
– Hash collision and integrity attack
– Integer Overflow and Underflow
– BatchTransfer Overflow (CVE-2018–10299)
– Unprotected SELFDESTRUCT
– Take ownership of a vulnerable contract
– DelegateCall vulnerabilities
….more

 

Key Learning Objectives

– Identify, exploit and create automated D16proof of concept of smart contract vulnerabilities exploitations
– Implement secure smart contracts
– Perform smart contract security audits

What will the students get

– 15 hands-on labs
– Final CTF
– Handbook with step by step solutions of the labs
– List of resources used during the course
