83721-cb[.]com
“Coinbase”
Ringkasan bukti
The domain 83721-cb.com was registered on February 28, 2026 through NameSilo, LLC and immediately began serving a crypto‑related impersonation campaign targeting Coinbase users. The site’s HTML title is reported as "Coinbase", confirming a deliberate brand‑impersonation tactic. Infrastructure analysis shows the domain resolves to the IP address 172.67.149.196, which belongs to Cloudflare, Inc. (AS13335) and is therefore hosted behind a CDN edge network. The domain uses Cloudflare’s default nameservers (justin.ns.cloudflare.com and tia.ns.cloudflare.com) but does not present an SSL/TLS certificate, leaving the connection unencrypted.
No HTTPS endpoint was observed before the site was taken offline. Reputation checks indicate that 83721-cb.com is listed on three independent security blocklists and has been flagged by 17 of 93 vendors on VirusTotal, suggesting a moderate to high confidence of malicious intent. The site is currently reported as offline, which limits further content analysis; no page screenshots or HTML samples are available.
Defensive services have already taken action: PhishDestroy, MetaMask, and SEAL have each blocked the domain. Given the confirmed brand impersonation, the presence on multiple blocklists, and the detection rate on VirusTotal, security teams should continue to enforce deny‑list rules for the domain, monitor the associated IP range for any re‑activation, and consider adding the IP address to network‑level block policies. Continuous observation of Cloudflare‑originated traffic for similar patterns is advised, as threat actors often recycle CDN infrastructure for new campaigns.
