guestdataupds[.]com

guestdataupds.com was registered through Dynadot Inc on August 05, 2026 and is currently active. The domain resolves to the IP address 104.21.51.9, which is part of Cloudflare’s global edge network, as indicated by the authoritative nameservers coleman.ns.cloudflare.com and emily.ns.cloudflare.com. The short registration window and immediate appearance on a security blocklist suggest an intent to exploit the fresh domain for malicious purposes.

The domain is listed on at least one public blocklist and has been explicitly blocked by the PhishDestroy service, confirming that reputable anti‑phishing feeds consider it hostile. VirusTotal has recorded a single positive detection among 91 scanning engines, showing that at least one AV product has identified the domain as suspicious. No additional evidence such as Safe Browsing verdicts, Open Threat Exchange (OTX) tags, SSL certificate details, HTTP response codes, trust scores, or page title information is presently available, limiting the depth of technical profiling.

Defenders should treat the domain as high‑risk based on the combined indicators: recent creation, Cloudflare hosting, blocklist presence, PhishDestroy block, and the VirusTotal positive. Recommended actions include adding the domain to network deny lists, configuring DNS filtering to drop queries, updating email security gateways to quarantine messages that reference the domain, and monitoring the associated IP for any anomalous traffic. Continuous re‑assessment is advised in case additional intelligence, such as further vendor detections or content analysis, becomes available.
