Network Security

5 Open Ports That Should Scare You

Ports 22, 23, 3389, 5900, and 8080 left exposed to the internet are an open invitation. Each one has a history of mass exploitation. Here is what to do about each one before an attacker finds them first.

Flutter Security

Why Your Flutter App Is Leaking Secrets

Most Flutter developers store API keys in dart files, compile them into the APK, and ship them to the Play Store. Decompiling takes 60 seconds. Use flutter_dotenv, certificate pinning, and server-side validation to stay safe.

Why I Build Security Tools in Go

Go's goroutines let you scan 10,000 ports concurrently with minimal memory. Compiled to a single binary with no dependencies. Cross-compiles to Linux, Windows, ARM in one command. For security tooling, nothing comes close.

Bot Development

How HackTheBox Changed My Career

I went from writing basic Python scripts to landing real security clients in under 18 months. HTB forced me to think like an attacker, understand real CVEs, and write custom exploits. Here is the exact path I followed.

Web Security

Why Your Login Page Is Probably Vulnerable

Most login pages fail on three things: no rate limiting, weak session tokens, and verbose error messages that tell attackers whether the username or password was wrong. Fix these three and you eliminate 80% of brute-force risk overnight.

OSINT

What Attackers Know About You Before They Strike

Before any attack, hackers spend hours in reconnaissance. Public GitHub repos, job postings, LinkedIn tech stacks, and misconfigured DNS records hand them everything they need. A 30-minute OSINT audit on yourself will shock you.

Hardcoded Secrets in APKs: A Silent Epidemic

Decompiling Android APKs takes under 60 seconds. In that time, you can extract hardcoded API keys, Firebase credentials, and database URLs left by developers. If your app is on the Play Store, assume it has been checked. Use environment variables and certificate pinning.
