3-day hands-on technical Workshop

Hacking Cryptography: Attacks, Tools & Techniques

This course turns you into a powerful weapon. You will know how applied cryptography works, how it’s commonly misused in the field and how this leads to exploitable bugs. By the end of the course, you will be among the very selected group of people that can identify, avoid and exploit vulnerabilities in code using crypto.

Crypto related bugs are super common. OWASP even ranks “Cryptographic Failure” as the second most common security vulnerability class in software. Yet, very often these vulnerabilities are overlooked by developers, code auditors, blue teamers and penetration testers alike. Because, let’s face it: Nobody knows how cryptography works.

During the course you will:

Understand how modern cryptography works.
Find common crypto vulnerabilities in real software.
Write crypto exploits for real software (and an IoT device).

Using case studies from our own pentesting and red teaming engagements, we’ll introduce core concepts of applied cryptography and how they fail in practice.

At the end of the course you will be able to spot an exploitable crypto bug from miles away (and be able to avoid them yourself)! No prior knowledge required.

Key Learning Objectives

Learn how modern cryptography operates. Learn what kind of guarantees are given by certain primitives, and which aren’t.
Understand how crypto primitives are combined into protocols.
Learn how cryptography is often misused in practice and how this misuse can be exploited.
Write exploits for systems using cryptography in an inappropriate way.
Evaluate program code that uses cryptography for proper usage.
Identify cryptographic schemes and potential vulnerabilities in black-box tests.
