Build your hacking empire from nothing. HackStack is an idle clicker set in a cybersecurity underworld. You tap to run exploits, deploy tools that earn while you sleep, research new tech, and build out your rig. It's a cyberpunk parody of the infosec world with real hacking history baked into every corner. EXECUTE exploits to earn CREDS, your in-game currency. Start with a humble Port Scanner. End up running Neural Exploits and a Digital Consciousness. Every tool you deploy keeps earning even when you close the app. RESEARCH 24 tools across 6 categories. Each one comes with an intel card covering real cybersecurity history and lore. 177 cards to find. BUILD YOUR RIG. Upgrade your CPU, RAM, GPU, Storage, Cooling, and PSU. Better hardware means faster research and access to higher-tier tools. EARN CERTIFICATIONS across three branches: Offensive, Defensive, and Management. 23 certs, 69 tiers. They shape how you play and what you can unlock. SURVIVE BREACHES. Phishing attacks, ransomware, DDoS, insider threats. They show up unannounced, they mess with your income, and you need to deal with them fast. COMPLETE DAILY OPS for XP. Quick wins, standard missions, and challenge-tier operations. Something different every day. PRESTIGE when you're ready. Wipe your progress, earn Shadow Creds, buy permanent upgrades, and come back stronger. Free to play. No pay-to-win.
