Practical Applications

Writing Shellcode and Security Applications

What is Shellcode?

Shellcode is small, assembly-written code designed to be injected and executed within another program, often used in security research.

How is Shellcode Used?

  • Penetration testing and exploit development
  • Security research and malware analysis

Example

Writing a shellcode that spawns a shell or opens a file.

Ethics and Safety

Learning about shellcode is essential for defending systems, not just attacking them. Always use this knowledge responsibly.

Examples

  • Creating a shellcode payload for a security test.

  • Analyzing malware behavior to develop better antivirus tools.
