cryptocurrencyinvestigationsbook[.]com

The domain cryptocurrencyinvestigationsbook.com was registered through Porkbun LLC on 2026-03-06 and is presently taken offline. DNS resolution points to the IP address 44.227.76.166, which belongs to the Amazon.com, Inc. network (AS16509) and is physically located in the United States. The domain is served by three Porkbun nameservers—curitiba.ns.porkbun.com, fortaleza.ns.porkbun.com, and maceio.ns.porkbun.com—consistent with the registrar's standard configuration. The site presented an expired‑domain page titled "porkbun.com | expired domain" and employed a Let’s Encrypt R12 TLS certificate, indicating a valid SSL handshake but offering no indication of the intended malicious content.

Threat intelligence classifies the domain as an investment‑scam phishing vector, and it has been listed on three external security blocklists. Detection services have flagged the domain, with five of ninety‑four VirusTotal scanners returning a positive indication. Additionally, the domain is blocked by PhishDestroy, MetaMask, and SEAL, reinforcing its categorisation as a phishing threat targeting cryptocurrency users.

While the offline status prevents live traffic analysis, the combination of registrar data, IP hosting, SSL usage, and multiple blocklist entries provides sufficient evidence for defensive controls. Defenders should continue to deny DNS resolution for the domain, maintain the existing blocklist entries, and monitor any future re‑registration attempts. Attribution beyond the current infrastructure remains uncertain, and no additional payload or kit information is available at this time.
