Native Code Crash Course

Dive head-first into understanding and hacking native code in this advanced 28-minute video session from HackerOne's Hacker101 series. Gain a solid foundation in computer fundamentals, memory corruption bugs, modern system protections, and techniques to bypass them. Learn about registers, physical and virtual memory, endianness, program counters, syscalls, shared libraries, and various tools like disassemblers, decompilers, debuggers, and hex editors. Explore critical vulnerabilities such as buffer overflows, out-of-bounds writes, and use-after-free errors. Discover defensive mechanisms like stack canaries and ASLR, and offensive techniques including information leaks and heap spraying. By the end of this crash course, acquire a comprehensive understanding of native code hacking, setting you on the path to mastering this complex subject.
