Linux x86 Assembly and Shellcoding

Trace the history of assembly language as a low-level machine code that gives maximum control, from 16-bit origins toward 32- and 64-bit architectures, laying groundwork for this course.

Discover how CPU registers store data for computation and hold function return values, reducing memory access time, learn about general-purpose registers, base pointers, source and destination indices, extended flags.

Explore the executable’s sections, including the text section with instructions, data section for initialized variables, the section for global variables, and the resource section for resources used by the program.

Learn to rebuild and debug a Linux x86 program using gdb, breakpoints, and disassembly to inspect registers, memory, and stack, and leverage plugins and GUI debuggers for visualization.

Master binary arithmetic in Linux x86 assembly by performing addition, subtraction, multiplication, and division, converting to binary, and using two's complement techniques.

Examine contraflow in Linux x86 assembly by using unconditional and conditional jumps. See how compare sets flags to drive greater than, less than, and equal jumps with practical examples.
