State of the Art of Ethereum Smart Contract Fuzzing in 2022 [EthCC5]

State of the Art of Ethereum Smart Contract Fuzzing in 2022 [EthCC5]

ByPatrick Ventuzelo

State of the Art of Ethereum Smart Contract Fuzzing in 2022 [EthCC5] Fuzzing is known as one of the most efficient techniques to find bugs in software. Sadly, when dealing with Ethereum smart contracts, the number of fuzzers and documentation available is really limited. During this talk, we will explain why fuzz testing EVM smart…

Introduction to V8 JavaScript Engine Grammar-based Fuzzing

Introduction to V8 JavaScript Engine Grammar-based Fuzzing

ByPatrick Ventuzelo

Introduction to V8 JavaScript Engine Grammar-based Fuzzing with Dharma In this short hands-on workshop, we will attack the V8 JavaScript Engine using grammar-based fuzzing. First, I will show how to download a version of V8 already compiled with addressSanitizer (ASAN). Then, I will introduce how to write a Dharma grammar and finally, we will use…

Solidity/Ethereum Smart Contract Audit using Slither – Blockchain Security #4

Solidity/Ethereum Smart Contract Audit using Slither – Blockchain Security #4

ByPatrick Ventuzelo

Solidity/Ethereum Smart Contract Audit using SlitherBlockchain Security In this video, I will show how to audit and find vulnerabilities inside an Ethereum smart contract written in Solidity using Slither, one of the best EVM smart contract analysis tools. https://youtu.be/s3FL5caAy5w You will get access of the complete tutorial with source code, cheat sheet and or complete…

Rust Fuzzing using cargo-libafl (LibAFL-based fuzzer)

Rust Fuzzing using cargo-libafl (LibAFL-based fuzzer)

ByPatrick Ventuzelo

Fuzzing Rust using cargo-libafl (LibAFL-based fuzzer) In this video, we are testing cargo-libafl, the new LibAFL-based fuzzer for Rust fuzzing. This new cargo utility is a replacement for (and a fork of) cargo-fuzz to use a LibAFL-based fuzzer instead of libfuzzer. Let’s see how it performs compare to libfuzzer. NOTES You will get access of…

Ethereum/EVM Smart Contract Reverse Engineering & Disassembly

Ethereum/EVM Smart Contract Reverse Engineering & Disassembly

ByPatrick Ventuzelo

Ethereum Smart Contract Reverse Engineering & EVM Disassembly Today I’m showing how EVM disassembly works and how to reconstruct the control flow graph (CFG) of an Ethereum smart contract when you only have access to the bytecode (closed-source). It’s really useful when you’re looking to analyze in-depth a contract at the EVM bytecode level. You…
