zyfai-app[.]xyz

Analysis indicates that zyfai-app.xyz is actively hosting a generic phishing page. The domain was created on February 21, 2026 and registered through NiceNIC International Group Co., Limited. Authoritative nameservers nile.ns.cloudflare.com and phoenix.ns.cloudflare.com resolve the domain to IP address 104.21.94.212, which is owned by AS13335 Cloudflare, Inc. in the United States. The web server reports an HTTP 403 status and delivers a page titled “Just a moment…”, consistent with Cloudflare’s challenge page. Detected technologies include Cloudflare Browser Insights, Cloudflare itself, and HTTP/3, confirming that the site relies on Cloudflare’s edge network. TLS termination is provided by a Google Trust Services certificate (WE1), indicating a valid SSL chain.

Reputation signals are strongly negative: Gridinsoft assigns a trust score of 0 / 100, and three of ninety‑three VirusTotal scanners have flagged the domain as malicious. The domain appears on one external security blocklist and is listed by PhishDestroy as a confirmed phishing source. No additional intelligence such as Safe Browsing or OTX entries is present, so the full extent of the campaign remains uncertain. The recent registration date and limited detection history suggest a short‑lived infrastructure typical of opportunistic phishing operations.

Defenders should block DNS resolution for zyfai-app.xyz, deny outbound traffic to its IP address, and add the domain to URL filtering and web‑proxy blocklists. Continuous monitoring of Cloudflare‑related traffic may reveal ancillary hosts or future migration to other IP ranges. Given that the site remains active, periodic re‑assessment is recommended, and any new detection or attribution should be shared with relevant threat‑intelligence feeds.
