About Daniel A.
From curiosity to systematic security testing
How It Started
From an early age, I was captivated not only by playing games but by uncovering glitches and exploits—understanding how systems function and where they might fail.
This curiosity led me toward game development. If I could break a game, perhaps I could create one. I often spent long hours focused on solving problems, though my ADHD meant I would frequently shift between projects, resulting in many unfinished works. Still, each experience deepened my understanding of system mechanics.
The Physical World
At some point, I became interested in lockpicking. The appeal was immediate: a physical system governed by rules and mechanisms that could be studied and understood through practice and patience.
I started with a basic set and gradually upgraded as my knowledge expanded, eager to learn about different lock types and techniques.
The Connection
Lockpicking revealed a striking similarity between physical and digital security: both rely on assumptions and have vulnerabilities that can be exploited when you grasp their inner workings.
Back to Digital
Working with physical security reignited my interest in digital systems, now from a security perspective. I began exploring digital penetration testing, initially through virtual machines. Eventually, I dedicated a device entirely to this purpose, allowing a more immersive and efficient learning experience.
While still developing my expertise, hands-on practice has been essential to my progress.
The Realisation
Exposure to stories about physical penetration testing made me recognise that the mindset I'd cultivated—seeking weaknesses, considering edge cases, and understanding systems—aligns closely with the demands of professional security assessment.
Although I haven't formally conducted penetration tests, analysing vulnerabilities has become second nature.
The Why
If a system can be breached, it is far better to have it tested ethically and secured than to wait for malicious actors to exploit it. Ethical testers prioritise safety and integrity; those with harmful intent do not.
Current Reality & Future Goals
Currently, I work a day job to cover my expenses, but my ambitions lie elsewhere. I aim to transform my skills and passions into sustainable income, preferably passive, so I can focus on growth without the grind of constant labour.
Lessons from all areas remind me that unattended small issues often lead to bigger problems—whether in physical security or everyday work.

How I Think
I approach systems with curiosity and determination. When I encounter something unfamiliar, I experiment until I understand it. I trust intuition but know that testing boundaries can reveal hidden weaknesses.
Failures provide valuable information, turning mistakes into opportunities for improvement. By grasping a system's logic, I can anticipate vulnerabilities and help address them effectively.
