account-alert-center-243[.]pages[.]dev

The domain account-alert-center-243.pages.dev was observed as a brand‑impersonation site targeting Facebook. The site was registered on 2026-03-03 through Cloudflare, Inc., and its authoritative nameservers are garret.ns.cloudflare.com and stevie.ns.cloudflare.com. DNS resolution points to IP address 31.13.66.35, which is located in the United States and belongs to ASN 13335 (Cloudflare, Inc.). The TLS certificate is issued by Google Trust Services under the WE1 root, indicating a valid HTTPS endpoint, and the server advertises HSTS and HTTP/3, consistent with modern CDN configurations.

A page title retrieved from the live endpoint reads “Facebook - log in or sign up”, matching the declared brand target of Facebook. Google Safe Browsing classifies the domain as social engineering, and the domain appears on a single external security blocklist; it is also listed by PhishDestroy as blocked. VirusTotal analysis shows that 14 of 93 scanning engines have flagged the domain, reinforcing the malicious assessment. The HTTP response currently returns status code 403, and the site’s overall reputation scores are extremely low: Gridinsoft assigns a trust score of 0 / 100, while Scamadviser rates it 1 / 100.

These metrics, combined with the presence on blocklists and the Google Safe Browsing flag, indicate a high‑risk profile despite the site being taken offline at the time of reporting. Defenders should incorporate the domain and its associated IP address into blocklists and intrusion‑prevention rules, monitor for any re‑appearance of the sub‑domain pattern “account‑alert‑center‑*.pages.dev”, and enforce strict outbound filtering for connections to this host. Continuous observation of Cloudflare‑registered domains that resolve to the same IP range is advised, as the infrastructure may be reused for future brand‑impersonation campaigns.
