AI Security Verdict

Moderate Risk

Confidence: 68%

5
Risk Score

Free-host subdomain named like a bank authentication step, reported once for phishing, funnels through 3 redirects to the real Santander site with no form captured. Phishing-style lure/redirect; do not interact.

Risk Factors (4)
Single-source phishing threat-intel report against the entry domain authenticate-user-online.web.app
Bank-authentication-themed hostname on a free .web.app hosting subdomain (actual creation date unknown, could be brand new)
Entry domain is unranked in Cisco Umbrella top 1M and its age/reputation are not attributable to the page
Multi-hop cross-domain redirect used as a funnel from an untrusted host toward a bank login destination
Safety Factors (6)
Redirect terminates on www.santander.co.uk, the brand's own established domain, so the rendered page is not brand impersonation
No credential, password or payment fields verified in the captured DOM
No hunting rule malware patterns, no IDS alerts, no credential exfiltration or suspicious JavaScript behavior detected
Third-party script hosts (Adobe, LaunchDarkly, OneTrust, demdex, santander.co.uk assets) are consistent with the real Santander site
No concrete malicious signal: the threat-feed matches name third-party or shared hosts, or rest on a single feed or a reputation label, so they were not counted; no hunting rule / Safe-Browsing / IDS / credential form / brand impersonation either. Elevated risk rested on domain age or reputation alone; clamped from 7 to 5
Verdict cited a credential/login form, but DOM analysis found no password field (real or disguised) or payment field, and no other hard signal — credential-phishing framing unsupported; risk adjusted from 5 to 5
Domain age information unavailable
