In the world of software security, fuzzing is a critical technique used to identify vulnerabilities in software by bombarding it with unexpected or malformed inputs. One of the most popular and ver...

Avoid NULL bytes in Shellcode 1. Use Registers to Zero Values (Instead of mov reg, 0) eor r0, r0, r0 // ARM (32-bit) xor eax, eax // x86 sub r1, r1, r1 // ARM Thumb 2. Use PC-Rela...

Shellcode Shellcode is a small piece of code used as the payload in an exploitation process. It typically executes a predefined set of actions within the context of a vulnerable application, often...

NEON SIMD (Single Instruction, Multiple Data) – Vector Operations NEON is an advanced SIMD (Single Instruction, Multiple Data) extension for ARM processors that provides hardware-accelerated vecto...

ARM processors support multiple instruction sets, including the ARM instruction set (a fixed 32-bit instruction set) and Thumb instruction sets (which primarily use 16-bit instructions but can also...

Immediate, Register, and Offset Addressing ARM provides several ways to access memory. These addressing modes are used to specify how the memory address for a load/store instruction is computed. ...

1. Setting Up the Environment If you are on an x86-based system (like a typical PC), you can use QEMU to emulate an ARM processor. sudo apt update sudo apt install qemu qemu-user qemu-system-arm ...

Data Processing Instructions Data processing instructions are used to perform arithmetic, logical, and comparison operations on data stored in registers. These instructions can directly affect the...

Basic Instruction Format: The basic format of an ARM instruction follows this structure: // <operation> <destination>, <operand1>, <operand2> ADD R0, R1, R2 // R0 = R1 +...
