zimbr-web-client-auth[.]netlify[.]app

This report analyzes the domain zimbr-web-client-auth.netlify.app. Based on the page title "Site not found," the domain does not host a functional website at this time. The domain name suggests an attempt to impersonate a web client authentication service, likely targeting users of the "Zimbra" collaboration software brand. The primary threat posed is credential harvesting; if active, the site would attempt to trick users into entering login credentials for a fake authentication portal.

Technical analysis reveals the domain is flagged as malicious by 13 out of 95 VirusTotal vendors, including ADMINUSLabs, Criminal IP, alphaMountain.ai, BitDefender, and CyRadar. It appears on two blocklists. The domain is registered through Netlify and resolves to IP address 18.208.88.157, hosted on AS14618 (Amazon.com, Inc.) in the United States. The SSL certificate is issued by DigiCert Inc, using the DigiCert Global G2 TLS RSA SHA256 2020 CA1. Nameservers are dns1.p04.nsone.net and dns2.p04.nsone.net.

The domain is currently offline (status: DOWN/OFFLINE). Despite being inactive, the domain's inclusion on multiple security blocklists and the high number of vendor detections indicate a confirmed history of malicious activity. The risk level is assessed as high due to the domain's association with credential theft and its presence on threat intelligence feeds.
