Firewall Defence: Web & Document Malware

The mailbox is the front door. Office macros, booby-trapped PDFs, LNK shortcuts, HTML smuggling and ISO containers, then an obfuscated JavaScript dropper campaign. 10 waves. Build the right security control beside the path before each attack arrives.

How to play

  • Each control fully stops only its own attack. A WAF does nothing to a brute-force bot. Pick the real control for each threat.
  • Upgrade controls twice. Each level is a real hardening step (bot management, number-matching push, micro-segmentation).
  • Read the threat intel before each new attack: what it is, a real log line, its MITRE ATT&CK technique and the control.
  • Answer a technical question after every wave for bonus coins. The attack log explains every leak.
  • Clear it by surviving all 10 waves with at least 8 of 20 health and 60% of questions right.
