Learn to break in.
So you can keep them out.
SiberangeX is a hands-on range of real vulnerable machines, OWASP-mapped attack labs, and CTF challenges. Read less. Exploit more — on targets you’re allowed to break. Made in Malaysia.
Enumerate the target, find a foothold, and capture the flag. Submit it in the panel to earn XP and climb the ladder.
Copy the flag above and submit it.
Don’t watch a terminal.
Type into one.
Boot a live box and poke around — a real filesystem, the Linux tools you know, pipes & redirection, a working nano editor. No install, no VPN, nothing to download.
You can’t defend
what you’ve never broken.
Slides and video courses teach you the words. They don’t teach you the moment a misconfigured permission becomes root. That only comes from doing it — safely, repeatedly, on a target built to be broken.
A place to practise the attack, not just read about it.
Spin up a real vulnerable machine, get a target IP, and work it end to end — recon, foothold, escalation, capture. Every box is intentionally broken and fully yours to take apart.
- → Isolated, disposable environments — reset any time.
- → A live objective, briefing, and flag check on every target.
- → Hints and full walkthroughs when you’re genuinely stuck.
Broken Access Control — 8 hands-on tasks on real authorization flaws.
Four moves. Every target.
Recon
Map the target. Ports, services, versions — find where it’s soft.
Exploit
Turn a weakness into access. Get your first foothold on the box.
Capture
Escalate, reach the flag, and submit it to prove you rooted it.
Rank
Earn XP, climb the ladder, and unlock harder machines and tracks.
One flag. Five moves.
This is a single box on the range — from an open port to root, the way an operator actually works. Scroll through it.
Find the doors
A service scan shows what’s listening. Two ports open — the web server is the obvious way in.
Read the map
Directory enumeration turns up a login page and an /admin route that answers with a telling 403.
Walk through
A broken access-control check lets a normal request reach the admin view. That’s the foothold.
Become root
A misconfigured sudo rule is a known path straight to root. No exploit kit — just the operator’s eye for a mistake.
Capture the flag
Read the flag, submit it, solve the box. XP lands and the next machine unlocks.
Three ways to get your hands dirty.
The OWASP Top 10, as things you break.
Ten categories of real-world web flaws — from broken access control to injection — each a set of guided, hands-on exploitation tasks ranked by category.
Full vulnerable environments over a lab VPN.
Quick single-flag machines to warm up, or complete boxes you connect to over VPN — enumerate, exploit, and compromise the whole target. Linux and Windows, Easy to Insane.
CTF flags across every category.
Web, Crypto, Forensics, OSINT and more — bite-sized puzzles that sharpen a single skill. Pick a category, find the flag, bank the points.

Reading about a vulnerability
isn’t the same as exploiting one.
A video course
You watch someone else do it. You finish the module. Faced with a real target and a blank terminal, you don’t know the first command to type.
SiberangeX
You get the target. You type the commands. You fail, adjust, and land the flag yourself — and that muscle memory is what actually transfers to the job.
Built for operators, students, and the educators who train them.
Running a classroom or a bootcamp? The Education Program brings the range into your curriculum — pre-configured environments, guided tracks, and progress you can actually see.
Your first flag
is one login away.
