kr97n[.]at

The domain kr97n.at was observed delivering a generic phishing payload and is currently taken offline. Registration data shows the domain was purchased through Dynadot LLC, a registrar that frequently appears in abuse reports. The authoritative nameservers are imani.ns.cloudflare.com and jakub.ns.cloudflare.com, indicating that the domain leveraged Cloudflare’s CDN and security services. DNS resolution points to IP address 172.67.208.35, which belongs to AS13335 Cloudflare, Inc. and is hosted in the United States.

An HTTP request to the domain returned a 200 status code and the page title "slon3.at" was retrieved, confirming the site was reachable before removal. Technical fingerprints include Cloudflare Browser Insights, Cloudflare, and HTTP/3, all typical of Cloudflare‑protected sites. Reputation signals are strongly negative: the domain appears on one security blocklist, has been blocked by PhishDestroy, and received a Gridinsoft trust score of 0 out of 100. VirusTotal analysis recorded two detections out of 94 scanned vendors, reinforcing the malicious classification.

While the site is no longer live, the infrastructure—particularly the use of Cloudflare’s network—remains reusable for future campaigns. Defenders should continue to block kr97n.at at perimeter filters, update URL allow/deny lists, and monitor related Cloudflare IP ranges for similar activity. Additional investigation of any residual traffic to the associated IP address may reveal reuse patterns. Organizations should also consider reviewing recent inbound logs for attempts to contact kr97n.at or its resolved IP, as remnants of the campaign could persist in compromised client browsers or automated tools.
