The domain advertising-account-activity-dashboard-b1y.pages.dev was registered on March 03, 2026 through Cloudflare, Inc. and resolves to the IP address 57.144.244.1, which belongs to AS13335 Cloudflare, Inc. in the United States. DNS resolution uses the Cloudflare nameservers clayton.ns.cloudflare.com and romina.ns.cloudflare.com. The site presents a TLS certificate issued by Google Trust Services under the WE1 profile, and the HTTP response returns a 403 status code. Technical fingerprints include HSTS, Cloudflare edge services, and HTTP/3 support.

VirusTotal records indicate that 11 of 93 security vendors have flagged the domain, and it appears on a single external blocklist. The domain is actively blocked by PhishDestroy and Google Safe Browsing classifies it as a social‑engineering threat. Independent trust‑rating services assign extremely low scores: Gridinsoft 0/100 and Scamadviser 1/100, underscoring the malicious nature of the infrastructure.

The page title returned by the server is "Facebook – log in or sign up", and the threat type is identified as brand impersonation targeting Facebook. No additional content analysis is available because the site is currently offline, leaving the exact phishing page layout and credential‑capture mechanisms unverified.

Defenders should immediately block the domain and its associated IP address at network perimeter devices. Adding the domain to internal URL filtering lists, as well as to external blocklists such as PhishDestroy, will mitigate exposure. Continuous monitoring of Cloudflare‑hosted IP ranges for similar activity is advised, given the ease of provisioning new domains on the same infrastructure. Organizations should also educate users about unsolicited login prompts referencing Facebook, reinforcing the need to verify URLs before entering credentials.
