us-coin-base-logn[.]pages[.]dev

Analysis of us-coin-base-logn.pages.dev shows a high‑risk brand‑impersonation campaign targeting Coinbase users. The domain was registered on February 21, 2026 through Cloudflare, Inc. and uses Cloudflare name servers (dave.ns.cloudflare.com, itzel.ns.cloudflare.com). DNS resolution points to IP 188.114.96.3, which belongs to AS13335 Cloudflare, Inc. in the United States, indicating the site was hosted behind Cloudflare’s edge network. The site serves HTTP/3 and enforces HSTS, and its TLS certificate is issued by Google Trust Services under the WE1 identifier, confirming a valid SSL chain.

The page title returned by the server is "Suspected phishing site | Cloudflare" and the HTTP status is 403, suggesting the content has been taken offline at the time of checking. Security aggregators have flagged the domain: Google Safe Browsing lists it as a social‑engineering threat, and PhishDestroy has added it to its blocklist. VirusTotal reports 11 of 95 scanners flagging the domain, and the site appears on a single additional blocklist. Gridinsoft assigns a trust score of 0/100, reinforcing the malicious assessment.

The evidence points to a crypto‑scam technique, explicitly labeled as a "Crypto Scam" and aimed at stealing credentials or funds by masquerading as Coinbase. While the exact phishing page content has not been retrieved, the combination of brand targeting, hostile page title, and multiple vendor detections provides sufficient confidence to classify the infrastructure as malicious. Defenders should block the domain at DNS and proxy layers, update intrusion‑detection signatures to include the observed IP and nameserver pair, and monitor for any re‑registration attempts or related subdomains. Continued observation of Cloudflare‑hosted assets for similar impersonation patterns is recommended.
