25web[.]whatsapwcso[.]com

Analysis of the domain 25web.whatsapwcso.com indicates a recently created infrastructure used for brand impersonation targeting WhatsApp users. The domain was registered on February 21, 2026 through Gname.com Pte. Ltd. and resolves to the IP address 38.55.19.47, which is hosted in the United States under ASN 8796 (FASTNET DATA INC). No TLS certificate is present, meaning the site would have been served over plain HTTP if it were active. The authoritative nameservers are elsa.ns.cloudflare.com and javier.ns.cloudflare.com, both Cloudflare‑managed, a pattern frequently observed in malicious hosting setups. The page title returned by the server was "whatsapp", matching the declared brand target and confirming the intent to masquerade as the official WhatsApp service.

Security‑vendor scans on VirusTotal show that 21 of 93 engines flagged the domain, reflecting a consensus of malicious behavior. The site appears on a single external blocklist and has been specifically blocked by PhishDestroy, reinforcing its classification as a phishing resource. Gridinsoft assigned a trust score of 0 out of 100, the lowest possible rating, indicating extreme suspicion. Current network checks report the domain as offline, suggesting the operators have taken the site down, possibly after detection.

Nevertheless, the underlying infrastructure—cloud‑fronted nameservers, the same registrar, and the same IP range—remains observable. Defensive teams should proactively block the domain and its resolved IP at perimeter firewalls and proxy filters, and add the registrar Gname.com Pte. Ltd. to watchlists for future malicious registrations. Monitoring of the associated Cloudflare nameservers for new subdomains that resolve to the same IP or nearby prefixes is advised, as threat actors often reuse these components.
