ad-account-policy-check-center[.]pages[.]dev

Analysis of the domain ad-account-policy-check-center.pages.dev indicates a high-risk brand impersonation campaign targeting Facebook users. The domain, registered on March 3, 2026, through Cloudflare, Inc., was taken offline by July 24, 2026, returning an HTTP 403 status. Infrastructure analysis reveals Cloudflare hosting (AS13335) with nameservers aiden.ns.cloudflare.com and jocelyn.ns.cloudflare.com, resolving to IP 157.240.253.35 in the United States. The SSL certificate, issued by Google Trust Services (WE1), and detected technologies including HSTS and HTTP/3, align with typical Cloudflare configurations, though these do not mitigate the malicious intent.

The page title, 'Facebook - Meld je aan of registreer je,' explicitly suggests an attempt to mimic Facebook's login interface, corroborating the brand impersonation classification. Google Safe Browsing has flagged the domain for social engineering, while PhishDestroy has actively blocked it. Detection metrics from security vendors are limited but notable: 14 of 93 vendors on VirusTotal flagged the domain as malicious, and it appears on at least one security blocklist. Trust scores from Gridinsoft and Scamadviser are critically low at 0/100 and 1/100, respectively, further supporting the malicious classification.

While the exact content and functionality of the phishing page remain unconfirmed due to its offline status, the combination of infrastructure, detection flags, and brand impersonation indicators strongly suggests a credential harvesting operation. Defenders are advised to treat this domain as malicious, block it at the network level, and monitor for related infrastructure, particularly Cloudflare-hosted subdomains under pages.dev. The use of a legitimate CDN provider underscores the need for continuous vigilance, as such services are frequently abused for phishing due to their perceived trustworthiness.
