Hacking crypto (cryptography! 🤪) without hard math: how to find bugs in implementation.👨🏻‍💻🔏👩🏿‍💻🤔💥

Security researcher Matt Byrdwell, aka Nerdwell, in his four-part blog series presents a practical hacker’s view of cryptography. He claims that real-world vulnerabilities rarely come from breaking math - but from breaking implementations.

The author goes through public security research publications and known vulnerabilities, presenting examples and deep dives into different ways to approach cryptography, depending on where and how it’s implemented (blockchain and cryptocurrencies included)

In a nutshell: The harder something looks, the less people test it. As a result - more bugs, less competition, higher rewards.

No matter how good you are at security research or hacking (or math), I recommend you read the articles below. You’ll find some interesting and useful ideas there. Enjoy - and if you know someone who might be interested as well, please share!
