Intermediate

4/52021

Python Programming for Hackers and Pentesters

Justin Seitz, Tim Arnold

Justin Seitz and Tim Arnold's hands-on tour of writing offensive tooling in Python: network sniffers, web scrapers, GitHub-based command-and-control, screen capture, keylogging, and Volatility extensions.

Beginner

Nmap Network Scanning

The Official Nmap Project Guide to Network Discovery and Security Scanning

Gordon Fyodor Lyon

Written by Nmap's own author, this is both a gentle introduction to port scanning and the definitive reference for every flag, timing knob, and NSE script the tool ships with.

Read this if

Working pentesters and red teamers who want to stop fighting other people's tools and start writing their own. The book that turns Python from a scripting language into an offensive multitool.

Anyone who runs Nmap regularly and wants to actually understand its output, and pentesters or admins who need the authoritative explanation of scan types and timing.

Skip this if

Beginners with no Python experience, or readers wanting a structured CS curriculum. Seitz and Arnold assume you can already program; the value is in offensive idioms, not language fundamentals.

Readers wanting a modern, broad recon toolkit. Skip this if you want coverage of cloud-era discovery; it is deep on one tool, not a survey.

Key takeaways

Most operational tools you use can be replaced by ~50 lines of Python that do exactly what you need; the book is a series of working examples of that thesis.
The networking, web-scraping and process-injection chapters individually pay back the cost of the book once you've used the patterns three times.
The 2nd edition (Python 3, modern libraries) is the one to buy; the first edition's Python 2 code is dated.

The difference between scan types (SYN, connect, ACK, idle) is about what the network tells you, not just speed.
Timing and performance tuning is where real-world scanning succeeds or gets you blocked, and the book treats it as a first-class topic.
The Nmap Scripting Engine turns the scanner into a lightweight vulnerability and discovery framework, and the reference chapters are the best documentation that exists for it.

How they compare

Black Hat Python and Nmap Network Scanning are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Black Hat Python is pitched at intermediate level. Nmap Network Scanning is pitched at beginner level. Read the easier one first if you're not yet comfortable with the topic.

Black Hat Python and Nmap Network Scanning both cover Tooling, Networking, so reading them in sequence reinforces the same material from different angles.
