Low Level (YouTube channel)

What the channel covers

Low Level is run by a vulnerability researcher (the channel describes him as having more than ten years in cybersecurity). The through-line is what happens beneath your code: memory, pointers, assembly, the kernel and the bugs that live there. Be aware of the current shape of the channel: most recent uploads are short reactions to security news, such as router vulnerabilities, kernel issues and large breaches. They are useful for staying current, but they are commentary, not lessons. The teaching material sits in the older series.

Where to start

• Learn Assembly as FAST as Possible: a compact introduction to reading and writing assembly, the best entry point if you have never looked below C.
• How Does Code Work?: short explanations of what compilers, memory and the CPU actually do with your program.
• Reverse Engineering Adventures: taking binaries apart to see how they behave, a good bridge into security work.
• Writing a Driver on the Raspberry Pi: Kernel Mode Programming: a project series that moves from user space into the kernel.
• The Future of Programming: Rust: why memory safety matters, from someone who spends his days finding memory bugs.
• Code Reviews: looking through real code with a security and correctness eye.

Who it suits

Students who know C basics and want to understand why buffer overflows, use-after-free bugs and similar flaws exist. It also suits developers drifting towards security, embedded or systems roles who want the mental model before the certifications. If you have never written C, start with a C or CS50 course first; many videos assume you can read pointers.

How to learn from it without getting stuck in tutorial loops

The news videos are easy to binge and teach little on their own. Treat them as a reading list: when a video mentions a bug class, look it up and try to reproduce a simple version yourself.

1. Pick one series, not the latest uploads, and watch it in order.
2. After each episode, write the same small program in C, compile it, and step through it in a debugger such as GDB.
3. Practise on deliberate targets: OverTheWire: Bandit for the command line, then CyLab Security Academy (formerly picoCTF) for beginner binary exploitation and reverse engineering problems.
4. Keep a notes file of every concept (stack frame, calling convention, ASLR) in your own words.

Pair it with on Sefism

• The Cybersecurity roadmap gives the order of topics, from networking and Linux to web and binary security, and its cheat sheet works as a quick revision companion.
• The CS core subjects roadmap and cheat sheet cover the operating systems and architecture background the channel assumes.
• For hands-on practice, TryHackMe and Hack The Box Academy turn what you watch into exercises.
• Operating Systems: Three Easy Pieces is the book to read alongside the kernel material.

Best for: intermediate learners who can write C and want to see systems and security from the attacker's side.
