whats-zbu[.]vip

This domain, whats-zbu.vip, is currently offline but was previously identified as a brand‑impersonation site targeting WhatsApp users. The site presented the page title “whats-zbu.vip”, which matches the domain, and no TLS certificate was observed, indicating that the service was delivered over plain HTTP. Registration information shows the domain was created on 5 October 2025 through the registrar Gname.com Pte. Ltd. The authoritative name servers are a.share-dns.com, a11.share-dns.com, b.share-dns.net and b11.share-dns.net, all of which resolve the domain to the IP address 20.2.208.17. The IP belongs to the AS8075 Microsoft Corporation network and is geolocated in Hong Kong.

Security‑visibility data indicate that the address appears on one blocklist and is actively blocked by PhishDestroy. Gridinsoft assigned a trust score of 0 out of 100, reflecting extreme malicious confidence. On AlienVault OTX the domain appears in seventeen separate threat‑intel pulses, reinforcing its reputation as a repeat offender. VirusTotal scanned the host and 16 of 95 security vendors returned a detection, confirming that multiple scanners consider the domain malicious.

The combination of a low trust score, multiple vendor detections, and repeated OTX mentions demonstrates a high likelihood that the site was used to harvest credentials or deliver malicious payloads under the guise of WhatsApp. Defenders should continue to block the domain at perimeter firewalls, DNS resolvers, and proxy filters, and should monitor for any resurgence of the same IP address or similar name‑server patterns that could indicate re‑hosting. Because the domain is already taken offline, incident response teams can focus on correlating any recent user‑reported WhatsApp‑related credential submissions with this indicator to assess potential compromise.
