Name of Training:

Hackable.sol: Smart Contract Hacking in Solidity


Identify vulnerabilities in Smart Contracts written in Solidity

Training description:

A 2-day full hands-on training where you will learn how to identify vulnerabilities in Smart Contracts written in Solidity. During the course, we will go over 12 labs inspired by the major hacks that saw companies lose millions of dollars, implement Smart Contracts, but also perform security reviews and detect security flaws using manual analysis and automated tools.

Some of the scenarios we will go through:

The list below contains some of the vulnerabilities that we will identify and fix in the labs:

  • Any user can cash out the money from the smart contract
  • Users can buy the subscription also with any wei amount
  • Any user can check the amount of money stored in the contract address
  • Reentrancy vulnerability
  • Block Timestamp Manipulation Vulnerability
  • Tx.origin: Authorization bypass
  • Integer Overflow and Underflow
  • BatchTransfer Overflow (CVE-2018–10299)
  • Unprotected SELFDESTRUCT
  • DelegateCall vulnerabilities
  • ....more

Trainer(s) bio:

Davide Cioccia is the founder of dcodx, a cybersecurity firm focusing on bridging the gap between development and security, working together with development teams to create and promote the DevSecOps security culture.

He is one of the first contributors to the OWASP Mobile Security Testing Guide and member of the SANS advisory board and Chapter Lead of DevSecCon Netherlands. He is also a speaker at international security conferences like BlackHat, OWASP AppSec, DevSecCon, Hacktivity and regional OWASP security events, where he presented different approaches and tools to automate mobile security testing in CI/CD, detect and prevent phishing attacks and automate infrastructure security in the release cycles.

On the personal side he loves to play racket sports, from tennis to padel, from ping pong to beach tennis. So hit him up for a match if you are in the Netherlands.
