zk-brevis[.]network

Analysis of zk-brevis.network shows an elevated‑risk generic phishing infrastructure that has been taken offline as of the report date. The domain was registered on December 28, 2025 through NiceNIC International Group Co., Limited and resolves to the Cloudflare‑owned address 188.114.96.3, located in the United States under ASN 13335. DNS resolution is served by Cloudflare name servers pranab.ns.cloudflare.com and selah.ns.cloudflare.com, and the site employed Cloudflare’s HTTP/3 protocol stack. An SSL certificate issued by Google Trust Services (WE1) was observed, indicating the use of a legitimate certificate authority to lend credibility to the site.

The page title returned by the server, "Cierpliwości...", provides the only visible content clue; no additional page content has been publicly recorded. VirusTotal scans captured detections from five of ninety‑three security vendors, confirming that multiple AV engines flagged the domain as malicious. AlienVault OTX listed the domain in a single threat pulse, and it appears on one external blocklist, where it has also been listed by PhishDestroy as a blocked resource.

The combination of a recent registration date, use of reputable hosting and TLS providers, and modest but consistent detection across independent threat feeds suggests a deliberate attempt to exploit the trust associated with Cloudflare and Google‑issued certificates. Defenders should add zk-brevis.network to deny‑list controls, monitor DNS queries for the associated IP address, and watch for any re‑registration attempts or derivative domains that reuse the same name‑server configuration. Continuous observation of VirusTotal and OTX feeds is recommended to capture any resurgence or related indicators of compromise.
