rainbowdefiai[.]net

rainbowdefiai.net is an active, high‑risk domain registered on August 26 2025. The site resolves to the IPv4 address 104.21.15.176, which belongs to the AS13335 Cloudflare network located in the United States. The domain is configured to use the Cloudflare nameservers bradley.ns.cloudflare.com and kami.ns.cloudflare.com, indicating that the attacker is leveraging Cloudflare’s reverse‑proxy and DDoS‑mitigation services.

The TLS certificate presented by the site is issued by Google Trust Services under the WE1 certificate profile, and the connection negotiates HTTP/3 with HSTS enforced. Front‑end analysis shows the presence of jQuery and Cloudflare Browser Insights scripts, confirming the use of typical Cloudflare‑provided web‑application stack. An HTTP request returns status code 200 and the page title “Rainbow DeFi AI”, which aligns with the declared brand target “rainbow” and the scam type “cryptocurrency”.

Reputation services have flagged the domain. VirusTotal records two positive detections out of ninety‑five scanned vendors, and Gridinsoft assigns a trust score of 0 / 100. The domain appears on two public blocklists and is listed as blocked by PhishDestroy and ScamSniffer. Both blocklists categorize the activity as a cryptocurrency‑related impersonation of the “rainbow” brand, consistent with the observed page title.

Defenders should treat rainbowdefiai.net as a confirmed cryptocurrency brand‑impersonation site. Network‑level controls should block outbound connections to 104.21.15.176 and to the associated Cloudflare IP ranges if not required for legitimate services. Email gateways and web filters should add the domain to deny lists, and incident response teams should monitor for any credential‑oriented payloads that reference the “Rainbow DeFi AI” wording. Continuous monitoring of the domain’s DNS records and blocklist status is advised, as the infrastructure may shift behind Cloudflare’s dynamic edge network.
