Custom Shellcode

Noun · Security & Infosec

Definitions

  1. Shellcode written or modified for a particular exploit context, architecture, or defensive environment instead of relying on generic public samples. Custom shellcode is often needed when size, behavior, or evasion constraints are tight.

    In plain English: Tailored exploit shellcode written for a specific target or constraint.

    Example: "The exploit used custom shellcode to avoid bad characters and stage a memory-resident loader."
