About this track
Vulnerability research methodology - lab setup, attack surface analysis, source code auditing, and concurrency vulnerabilities.
The VR Foundations track collects 4 modules and 16 lessons into a single ordered path. Each module ends with a checkpoint quiz; passing the checkpoint unlocks the next module so you can track your progress without guessing whether the material has stuck.
You start with "Introduction to Vulnerability Research" and finish on "Advanced Concurrency". The whole track sits inside the Vulnerability Research area of the curriculum, so the writing assumes the prerequisites listed above and skips ground that an earlier track has already covered.
What this track covers
- Introduction to Vulnerability Research — Learn the discipline of vulnerability research - from the lifecycle of a vulnerability through CVE scoring to responsible disclosure, and set up a lab environment for hands-on bug hunting.
- Source Code Auditing — Master the art of reading code to find vulnerabilities - from source-sink analysis and taint tracking to pattern-based auditing with tools like Semgrep and CodeQL.
- Concurrency & Race Conditions — When multiple threads access shared resources, timing becomes everything. Learn how race conditions arise, why they are hard to find, and how they create security vulnerabilities.
- Advanced Concurrency — Go beyond mutexes and basic locks. Explore lock-free programming, memory ordering, subtle concurrency bugs, and high-performance concurrent data structures.
How the track works
Every lesson is a short page with diagrams, runnable examples, and the kind of edge-case footnotes you usually only find in textbooks. Where it makes sense, the lesson is paired with a CPU simulation or a coding challenge so you can poke at the idea instead of just reading about it.
The lessons themselves are free to read with a free account. The 4 checkpoint quizzes that gate the next module are also free, as are the lesson IDE and CPU simulations. Optional 777-tier tools — the step-through debugger, decompiler, ROP gadget builder, heap visualiser, and exploit labs — sit alongside the lessons but are not required to follow the track from start to finish.
You can jump in at any point. Be Bitwise is built around a free forever curriculum, with no time limits and no expiring access. Pick the next lesson when you have an hour; come back when you do not.
