purchase3-blockdag[.]live

The domain purchase3-blockdag.live was observed hosting a banking phishing campaign that impersonates Chase. Infrastructure analysis shows the site was protected by Cloudflare, using HTTP/3 and presenting a TLS certificate issued by Google Trust Services under the WE1 root, indicating a legitimate certificate chain but not an assurance of content safety. DNS resolution points to the IPv6 address 2606:4700:3035::6815:30e, which belongs to Cloudflare’s AS13335 network located in the United States. The authoritative nameservers are bella.ns.cloudflare.com and khalid.ns.cloudflare.com, both Cloudflare‑managed, confirming that the domain’s hosting and DNS are fully within Cloudflare’s infrastructure. The HTTP response returned a 403 status code, and the page title displayed "Just a moment...", a generic placeholder often used by Cloudflare’s challenge page.

The site was registered through Web Commerce Communications Limited, a registrar that frequently appears in abuse reports, though no registration date is supplied. Malware analysis indicates the use of an "Airdrop Scam" phishing kit, consistent with the reported banking phishing classification. The domain appears on four independent security blocklists—PhishDestroy, Polkadot, Enkrypt, and Codeesura—demonstrating that multiple threat‑intelligence feeds have flagged it. VirusTotal scans show ten of ninety‑five antivirus engines flagged the domain, providing additional corroboration of malicious intent.

Current status is offline, suggesting the operators have taken the site down, but the infrastructure artifacts remain useful for attribution and mitigation. Defenders should continue to block the domain and its associated IP range, monitor for re‑use of the same Cloudflare account or nameservers, and incorporate the observed indicators—TLS issuer, HTTP status, page title, and kit name—into detection rules.
