Part 7 – Putting It All Together (Final Class + Exploit Skeleton Integration)

Assemble the full FileTransferServer; map it into an exploit skeleton with a standardized artifacts layout.

Learning Objectives

• Assemble a cohesive FileTransferServer with clear constructor parameters and defaults.

• Integrate the server into an exploit skeleton using callbacks and lifecycle hooks.

• Standardize artifacts layout and naming across tools for repeatable workflows.

Goals

• Merge features into a cohesive FileTransferServer.

• Provide a clean constructor with sensible defaults.

• Document public methods and calling conventions.

• Integrate with a standard artifacts/logs directory layout.

Key Terms

• Artifacts Root: Top directory for all run outputs and logs.

• Run ID: Time-based identifier to group artifacts from a single execution.

• Lifecycle Hooks: Explicit points to start/stop services or record evidence.

What You’ll Build

• Final class with:

  • Configurable file_path, save_dir, direction (download/upload/both).

  • limit, encoded mode, randomized route, port.

  • Optional HTML landing page.

  • on_transfer callback, start()/stop(), __repr__.

  • Logging wired throughout.

• Integration pattern with a canonical artifacts layout.
