beta-polyclaude[.]xyz

Analysis of beta-polyclaude.xyz, created on 22 June 2026 and registered through NICENIC INTERNATIONAL GROUP CO., LIMITED, indicates a high‑risk phishing infrastructure targeting cryptocurrency users. The site presents the page title “PolyClaude — Automated Trading Agent for Polymarket,” and is classified as a Crypto Drainer. The TLS certificate is issued by Let’s Encrypt (identifier YE2), confirming the use of a valid but easily obtainable certificate. HTTP requests return status 200, suggesting the server actively serves content. Infrastructure lookup resolves the domain to IP 2.26.254.142, located in the Netherlands and belonging to ASN 198550 (Node Host Limited).

The domain is hosted on Cloudflare nameservers eloise.ns.cloudflare.com and lennox.ns.cloudflare.com, a common choice for fast‑flux or evasive operations. Reputation services flag the host aggressively: Gridinsoft assigns a trust score of 0 / 100, three independent security blocklists list the domain, and AlienVault OTX reports inclusion in fourteen threat‑intel pulses. VirusTotal analysis shows 14 of 91 scanners flag the domain, reinforcing the malicious assessment. The domain is already blocked by PhishDestroy, MetaMask, and SEAL, indicating that major anti‑phishing and cryptocurrency wallet protections have incorporated the indicator. However, the presence of a legitimate‑looking certificate and a functional HTTP response may allow the site to bypass naïve URL‑based filters.

Defenders should continue to enforce blocklist rules that include beta‑polyclaude.xyz, monitor DNS queries for the associated IP range, and consider pre‑emptive URL filtering in web gateways. Users of Polymarket or related crypto platforms should be warned that any unsolicited request referencing “PolyClaude” is likely malicious. Incident response teams should capture TLS handshakes, preserve HTTP traffic, and submit samples to malware sandboxes for further behavioral analysis.
