Reverse-Engineering for learning assembly-level binary and firmware analysis from scratch

A free, lesson-by-lesson curriculum teaching reverse engineering across x86, x64, ARM, AVR, RISC-V and Wasm targets, aimed at analysts working on authorized malware and embedded research.

Tool	mytechnotalent/Reverse-Engineering — a free comprehensive reverse engineering tutorial spanning x86, x64, 32-bit/64-bit ARM, 8-bit AVR and 32-bit RISC-V architectures
Category	Educational curriculum / assembly-language and binary analysis training
Primary Use	Building foundational RE skills with GDB, Ghidra, and hand-written Assembly across desktop and embedded targets in a lab setting
Safe Use	Self-paced study material for security professionals, students, and defensive analysts practicing in personal labs, CTFs, and authorized engagements only
Telemetry Note	Purely educational content with no runtime footprint; defenders benefit indirectly because the same GDB and disassembly tradecraft taught here underpins malware triage workflows

mytechnotalent/Reverse-Engineering is one of the most starred educational repositories in the offensive security space, sitting at roughly 14,287 stars with Apache-2.0 licensing and its primary language tagged as Assembly — an accurate signal of what the content actually is. Unlike a utility you install, this is a longitudinal curriculum: a table of contents enumerating dozens of courses, from the classic x86 Course through ARM-32, ARM-64, x64, RISC-V, AVR, Wasm, and a rapidly expanding set of embedded tracks built around the Pico and RP2350 platforms. The README is effectively a living syllabus, with the latest entry at the time of this writing being Lesson 297 of the Embedded Hacking Course, covering debugging the floating-point data type on the Pico 2.

The pedagogical structure deserves attention because it reveals how the author, a well-known contributor through the DC540 hacking community, sequences skill acquisition. Each module follows a rigid triad: ASM Program, then ASM Debugging, then ASM Hacking — write it, watch it execute under a debugger, and finally modify its behavior at the instruction level. This mirrors how professional reverse engineers actually internalize a target: comprehension first, observation second, controlled mutation third. The x86 Course opens with goals, static versus dynamic analysis techniques, and basic malware taxonomy before a single instruction is disassembled, which is the right ordering for newcomers who often jump straight into tooling without a mental model.

Early lessons deliberately slow down. Parts 5 through 8 cover the binary and hexadecimal number systems, transistors and memory, and the meaning of bytes, words, and double words — culminating in the student's first GDB session inspecting real memory and instructions. Parts 9 through 16 walk the x86 architecture proper: general-purpose registers, segment registers, the instruction pointer, control registers, flags, the stack, and the heap. This is unglamorous material, but it is exactly the foundation that separates someone who can read a decompiler's pretty pseudocode from someone who can reason about a stripped binary when the decompiler fails, which it routinely does on obfuscated or embedded code.

The environment instructions are refreshingly minimal and reproducible: install Ubuntu Linux, install vim, and start assembling and debugging. That frugality matters. There is no dependency on commercial disassemblers, no magic VM appliance — the toolchain is gcc/as, GDB, and later Ghidra for the higher-level courses. For teams onboarding junior analysts, this means the entire curriculum can be stood up in a disposable lab VM at zero cost, and every artifact a student produces is one they built themselves, sidestepping licensing questions entirely when training material might be shared across a large cohort.

The companion ebook is the backbone of the written material: the README repeatedly links the free Reverse Engineering e-book and PDF, assembled by 0xInfection, hosted separately. Every lesson row in the README points back to that book rather than inlining full prose, which keeps the repository a navigable index while the deep explanations live in a versioned document. Operators evaluating this for a training program should treat the repo as the lesson tracker and the PDF as the textbook; both are free and the Apache-2.0 license permits redistribution and adaptation, which is useful for building internal coursework.

Beyond the core tracks, the README functions as a hub for the author's wider ecosystem, and the sprawl is instructive about where the field is heading. The Hacking Rust Course, Hacking Embedded Rust Course, and Go Hacking Course acknowledge that compiled Rust and Go binaries now appear routinely in real incident response, and their runtime characteristics — panic tables, goroutine schedulers, aggressive inlining — break naive analysis habits formed on C. The Wasm Course and its embedded variants (Embedded Wasm UART Echo, Blinky, Button, Servo) extend the same discipline to a bytecode format that increasingly shows up in edge runtimes and sandboxed plugins.

The embedded and RF-adjacent satellites are worth flagging for defenders on hardware-assigned teams. The RP2350 UART Driver and Blink Driver courses exist in both ARM and RISC-V variants of the same functionality, which is a quietly clever teaching device: implementing the identical driver twice across two ISAs forces the student to separate architecture-independent concepts from instruction-set specifics. The linked Ghidra plugins G-AVR and G-Pulley extend disassembly support toward 8-bit AVR microcontrollers, a class of chip that consumer IoT firmware teams constantly encounter and that mainstream tooling handles poorly.

For purple-team and CTF organizers, the repository also hosts the DC540 hacking challenge series, challenges 0x00001 through 0x00009, spanning MicroPython, C, assembler, and Windows targets, some deliberately labeled UNKNOWN to force fingerprinting from raw artifacts. These pair naturally with the coursework as capstone exercises, and because everything is self-contained and lab-oriented, they slot cleanly into authorized training programs. The STEM section — Python For Kids and Python Zero To Hero — plus AI-adjacent entries like TinyGPT round out a portfolio that is clearly aimed at growing the talent pipeline rather than at operational tooling.

From a compliance and safety standpoint, nothing in the README constitutes an attack recipe. The malware-related lessons discuss the basic forms of malware and the two canonical analysis techniques, static and dynamic, in educational terms; the hacking exercises mutate programs the student compiled themselves. That makes the repository appropriate reading for defensive analysts, students, and professionals preparing for authorized engagements, and inappropriate for nothing. The natural next step for a reader is to clone the repo or simply read it in order, grab the free PDF, set up an Ubuntu VM with GDB, and start at Lesson 1 — the curriculum rewards linear progress more than cherry-picking.

Where this fits in a working professional's calendar is the honest caveat: this is a long-haul commitment, not a reference you consult mid-engagement. Its value is compounding — the register-level fluency built in the x86 and ARM tracks transfers directly to triaging stripped firmware dumps and decompiler-resistant samples later. For a blog audience that lives in new tooling week to week, mytechnotalent/Reverse-Engineering is the rare GitHub artifact that appreciates with age: a maintained, freely licensed, architecture-spanning foundation that makes every subsequent tool on this site easier to use well.
