BadIIS Isn’t Enough: The IIS Module + HTTP Fingerprints That Catch SEO-Fraud Cloaking

🚨 Your “boring” IIS server just got a side hustle: casino redirects + SEO fraud.

And vendors are slapping different stickers on the same-ish mess: Talos’ UAT-8099 vs WithSecure’s WEBJACK. Same neighborhood, different name tags.

Here’s the part defenders keep missing: “BadIIS” alone isn’t a hunt. The money is in the operator fingerprints:

  • new IIS modules / weird DLL names + staging paths

  • $-suffixed local accounts (because subtlety is dead)

  • tunnel/remote tooling + header-based cloaking (UA/Referer/Accept-Language)

If your detections are split by vendor labels, you’re basically running four playbooks for one problem. 🤦‍♂️

What’s your reality check: do you still have IIS boxes no one “owns,” but everyone panics over when Google starts ranking them for gambling?
