still-math-b030[.]lenhancute1602[.]workers[.]dev

still-math-b030.lenhancute1602.workers.dev was observed hosting a generic phishing campaign. The domain was created on March 23, 2026 and is registered through Cloudflare, Inc. DNS resolution points to the IP address 104.21.5.235, which belongs to Cloudflare's network in Canada. The site presented an HTTP 404 response and its page title mirrored the full subdomain, offering no additional context. TLS negotiation succeeded using a Let's Encrypt certificate identified as “E8”, indicating the presence of a valid, publicly‑trusted certificate.

Header analysis revealed the deployment of HSTS, Cloudflare services, and HTTP/3, all typical of Cloudflare‑protected sites. Reputation services have flagged the domain: it appears on one security blocklist, received a Gridinsoft trust score of 0 / 100, and was blocked by the PhishDestroy platform. VirusTotal scans show that ten of ninety‑four security vendors flagged the domain as malicious, reinforcing the suspicion of phishing activity. The domain is currently offline, consistent with the “taken offline” status reported.

While the page content has not been captured, the combination of a recent registration, Cloudflare‑based hosting, a valid TLS certificate, and multiple vendor detections strongly suggests that the domain was intentionally created to host a phishing payload. Defenders should continue to block the domain at perimeter controls, monitor the associated IP address for any re‑use, and add the domain to internal blacklists. Ongoing observation of Cloudflare‑issued certificates for newly registered subdomains can provide early warning of similar campaigns.
