CTF hacking game: capture the flag & penetration testing in a Linux terminal
A hacking game where you type real commands. HackLab puts you in a Linux terminal against simulated targets: scan, analyze, exploit, capture the flag. Learn ethical hacking and cybersecurity by doing. No prior experience needed, and nothing you touch is a real system.
▸ A REAL TERMINAL, NOT A QUIZ
Type the commands professionals use: nmap, curl, sqlmap, ssh, grep and more. Every command is parsed and answered with realistic output. Stuck? Tap a suggested command, or ask for a hint in three levels, from a nudge to a near walkthrough.
▸ PENETRATION TESTING MISSIONS: SCAN → ANALYZE → EXPLOIT
Each mission teaches one skill: port scanning, service enumeration, SQL injection, XSS, credential attacks, log analysis, privilege escalation. Defense missions flip the script: detect the attacker, contain the breach, harden the service.
▸ CAPTURE THE FLAG (CTF)
Play CTF challenges, join live CTF events and solve bounties: mini CTFs built by other players. Find the hidden flag, submit it, earn XP.
▸ 15 WAYS TO PLAY
Operations for every mood:
- Live duel: race another player through the same mission
- Boss raid: everyone hits one target each week
- Crew: keep a streak alive with your team
- Range: free-play terminal against today's target
- Speedrun: beat your own ghost
- Adversary: a defender that reacts to noisy commands
- Triage, Chain, Relay, Cell, Post-mortem and Case Files: short defensive drills
- Daily contract: a fresh mission every day
▸ LINUX TERMINAL SKILLS
The terminal takes real commands (ls, cat, grep, nmap, curl, ssh, sqlmap), so every session builds habits you can reuse in a real Linux terminal.
▸ SCAM SHIELD
New to security? Short, tap-only stories inside a pretend phone show how accounts actually get stolen, and how to spot the trick before it works on you.
▸ STORY MODE AND LESSONS
Follow a story campaign, or learn step by step in the Learn tab. Each lesson ends with a two-minute lab so the idea sticks.
▸ RANK UP
Earn XP from Script Kiddie to Legend, keep a daily streak, unlock badges and climb the global and weekly leaderboards.
▸ CERTIFICATE (PRO)
Pass the HackLab exam to earn a certificate with its own verification link you can share on LinkedIn.
▸ SAFE AND LEGAL BY DESIGN
Every target is simulated. HackLab teaches how attacks work so you can defend against them and practice for CTF competitions and authorized penetration tests. Never use these techniques on systems you do not own or have permission to test.
▸ FREE AND PRO
Start free with a daily mission. Pro removes the daily limits on missions and operations and adds unlimited hints, the AI mentor and the certificate exam. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your Google Play subscriptions.
