I already come from a cybersecurity background.
I know the tools, the workflows, the methodology.
But recently I noticed a problem.
I was getting fast… and at the same time getting dependent.
Between ready-made tools, frameworks, and AI assistance, it became very easy to reach results without always understanding the mechanics underneath. Useful in the short term, dangerous in the long term. Especially for exploit development.
So I’m doing something intentional:
I’m going back to scratch mode.
No copy-pasted payloads.
No instant exploit generators.
And as little external assistance as possible while building.
The goal isn’t productivity.
The goal is rebuilding instinct.
Why Python?
Because Python sits exactly between scripting and low-level thinking.
It forces you to:
- control execution
- parse raw output
- interact with the OS
- automate recon
- reason about logic
It’s the perfect language to rebuild muscle memory before diving deeper into exploitation and binary work again.
And I’m doing it inside Vim.
Not for aesthetics.
Because during real testing environments you don’t get your preferred setup. Sometimes you only have a terminal and a shell account. If you can work efficiently there, you can work anywhere.
What I Built Today
Instead of exercises, I wrote a small reconnaissance utility.
It currently:
• performs ARP discovery
• enumerates local hosts
• runs a service scan through Python control
• parses results to detect open ports
Nothing revolutionary.
That’s the point.
I’m not trying to build a new scanner.
I’m rebuilding the habit of writing tools instead of relying on them.
Why I’m Doing This
Exploit development and vulnerability research depend on understanding behavior, not memorizing commands.
When you rely entirely on automation, you recognize patterns.
When you build things yourself, you understand causes.
I want to be comfortable again with:
reading raw output,
writing small utilities,
debugging logic manually,
and knowing what actually happens under a scan.
This is less about learning Python and more about recalibrating thinking.
Next
Next step is removing external scanners from the workflow and writing a socket-based port scanner directly in Python, just to observe what a scan actually is at the network level.
The objective of this series isn’t speed.
It’s rebuilding the habit of solving problems with reasoning first and tools second.
Day 1 complete.
