AI Security Verdict

Moderate Risk

Confidence: 55%

Risk Score

Thin .web.app page copying Zimbra's meta description under a 'zimbra-security'+digits subdomain — brand mismatch with no form and no IoC. Consistent with a phishing shell, but unconfirmed; treat with caution.

Risk Factors (5)

Zimbra brand strings used on a non-Zimbra domain (brand mismatch)

Suspicious subdomain naming: brand + 'security' + random numeric suffix

Domain unranked in Cisco Umbrella top 1M

Content is a thin, generic shell (title 'Background') that does not describe a real service

External domain reference app42.host of unexplained purpose

Safety Factors (5)

No credential, login or payment form on the page

No Indicators of Compromise matched against the page or its resources

No YARA malware patterns and no known malicious kit in the roster

No network IDS alerts and no cross-origin credential/exfiltration behavior

All JavaScript, where present, served from the site's own domain

Domain age information unavailable
