AI Security Verdict

Moderate Risk

Confidence: 68%

Risk Score

Deceptive Sparkasse 'S-ID check' hostname on free Firebase hosting redirecting to an unrelated domain, with a phishing-redirect IDS alert. No live credential form captured (page errors 502), but the infrastructure pattern is malicious.

Risk Factors (4)

Deceptive hostname imitating a Sparkasse S-ID verification page on a non-Sparkasse domain

Cross-domain redirect from firebaseapp.com to an unrelated domain (app-nachrichten.top)

Free instant-hosting tenant with unknown subdomain creation age

ET PHISHING Possible Phishing Redirect IDS alert (informational on its own, corroborates the redirect chain)

Safety Factors (5)

Final page body is only a 502 Bad Gateway error page — no credential or payment form is actually served or captured

Zero forms, password fields, payment fields and no cross-origin credential exfiltration detected in the captured DOM

No threat-intelligence Indicators of Compromise, no YARA malware matches, and no known malicious kit identified

All JavaScript (none behavioral) originated from the site's own domain; no third-party script hosts

No concrete malicious signal (no IoC / YARA / Safe-Browsing / IDS / credential form / brand impersonation) — elevated risk rested on domain age or reputation alone; clamped from 7 to 5

Domain age information unavailable
