5 Cybersecurity Paths

Each path focuses on a distinct threat domain. Pick your area and dive into guided labs built around real-world attacker techniques.

Windows Malware

From malware static triage to x64dbg unpacking, anti-debugging bypass, process injection and hollowing analysis, C2 configuration extraction, and MITRE ATT&CK-mapped DFIR reports — all in isolated FLARE-VM labs with professional-grade tooling.

Phishing with OSINT

Detect, analyze, and investigate phishing campaigns end-to-end, email forensics, SSL/TLS analysis, domain intelligence, malicious document triage, and threat actor attribution with professional OSINT tools.

How Our Labs Work

Watch the real lab experience exactly as any student sees it — submitting flags, earning points, and unlocking the next step in the guide, while a separate tab runs the actual VM with every tool already installed and configured.

Secure by Design

Every session is isolated, ephemeral, and safe

Fully isolated VM

No malware samples ever touch your machine. Every session runs in a hermetic environment that resets on exit.

Pre-loaded toolchains

FLARE-VM, REMnux, Ghidra, Wireshark and more, all configured and ready. No setup, no version conflicts.

Ephemeral sessions

Each lab session is time-boxed and self-contained. When you're done, the environment disappears with no persistence risk.

Reproducible scenarios

Every lab runs identically for every student. Unlimited restarts within your maximum lab window so you can retry several times, explore, and learn at your own pace.

Labs Frequently Asked Questions

Common questions students ask before starting hands-on practice.

No. Labs run in fully isolated cloud VMs prepared by HTK, so malware samples and tooling never touch your local operating system.

Yes. You can restart sessions and retry objectives as many times as needed within your maximum lab window.

Each lab uses CTF-style flags and objective checks to validate your work instantly. You always know when a step is correctly solved.

Both. HTK paths include beginner and intermediate levels, with step-by-step guided progression from foundations to complex scenarios.

Each lab VM comes pre-loaded with the relevant toolchain for the path: Ghidra, x64dbg, Wireshark, YARA, MobSF, and more depending on the course. No manual setup required.

Most sessions are designed for 45–75 minutes, but you can take as long as you need within the session window.

Beginner labs include guided instructions and context for each step. No prior cybersecurity experience is required, just follow the objectives.

Your flag submissions and scoring are saved to your dashboard permanently. Lab environments themselves are ephemeral and reset between sessions for security.
