Public exploits rarely work out of the box. Hardcoded IPs, wrong offsets, missing dependencies, and incompatible target versions all require modifications. PEN-200 teaches you to read exploit code, identify what needs changing, cross-compile for the target architecture, and troubleshoot when execution fails. This module bridges the gap between finding an exploit and getting a working shell.

## Payload Delivery and Shell Handling

After adapting an exploit, you need a reliable payload and a stable shell. Reverse shell one-liners cover most situations, but choosing the right payload depends on what interpreters are available on the target. Upgrading from a raw shell to a fully interactive TTY is essential for running tools like sudo and su.

> HackIndex does not currently have dedicated pages for memory corruption exploit modification or cross-compilation. Refer to the PEN-200 course material for buffer overflow exploit fixing and binary payload development.
