Cybersec Research · App Dev · AI Lab · 🇵🇭
An information-security & technical journal — plus the tools we build. We share what we learn as penetration testers, programmers, and network administrators so others can understand cyber risk and defend against it.
Built by us
Software we design and ship — and where new releases get announced.
Your day, on the record
Offline-first daily logs, notes, tasks, photos and voice memos for any project. Installs like an app, works with no signal, and syncs privately to your own Google Drive.
Plan, lead & play — in one place
The all-in-one app for worship teams: song charts with chords, one-tap transpose to any key, and a dashboard for members, trainings and schedule. AI practice tools on the way.
// AI Lab
Agents, automation and AI-assisted security & developer tooling — documented as it ships.
From the journal
Hands-on guides on penetration testing, hacking tools, networking, and the systems we live in.

In Part 1 we covered PHP's basic syntax. As promised, this time we'll look at variables and constants — the two ways PHP stores information for you to use later.

SQL injection broke databases. Command injection broke shells. Prompt injection breaks AI — and as we wire LLMs into agents and tools, it's the #1 risk to understand.

Who we are
Hi, I'm Acronix — a Certified Ethical Hacker and computer enthusiast since the year 2000.
We are a team from Asia with different backgrounds and experiences. Some of us are programmers, some are network administrators, but we are mostly penetration testers.
We started this blog to help out those who are technologically challenged, but it later became a technical journal where we share our knowledge, expertise, techniques, and discoveries. We focus on cybersecurity to help others understand the reality of cyber risks, threats and vulnerabilities — and to learn how to defend against cyber attacks. It's our way of giving back to the community and helping ethical hackers expand their pentesting methodology and tools.
It is our hope that the little effort we put here can help make the Internet a better place.
