promptai[.]network

Analysis of the domain promptai.network indicates it was operating as a generic phishing site targeting users with a false 'Autonomous Research Agent' service. The domain, registered on February 22, 2026, through NiceNIC International Group Co., Limited, resolved to the IP address 35.157.26.135, hosted on Amazon.com, Inc. infrastructure (AS16509) in Germany. The site presented a page title of '$PROMPT — Autonomous Research Agent,' suggesting an attempt to impersonate a legitimate research or AI-driven service, though no specific brand affiliation was confirmed in available data. Infrastructure analysis reveals the use of Netlify for hosting and HSTS implementation, alongside nameservers managed by NS1 (dns1-4.p03.nsone.net).

The SSL certificate was issued by Let's Encrypt, a common but not inherently malicious provider. Detection data shows the domain was flagged by two of 95 security vendors on VirusTotal and appears on at least one security blocklist, including PhishDestroy. Gridinsoft assigned a trust score of 0/100, further indicating elevated risk. The domain was taken offline prior to July 24, 2026, though residual DNS records may persist.

Defenders should treat any residual resolution or cached content as malicious and prioritize blocking the domain, its resolved IP, and associated nameservers in perimeter defenses. While the exact phishing mechanism remains unconfirmed due to the site's offline status, the combination of low trust scores, blocklist inclusion, and impersonation of an AI-related service warrants continued monitoring for related infrastructure or resurfacing activity. No evidence links this domain to a specific phishing kit or known threat actor group at this time.
