ch-angenw[.]at

ch-angenw.at was observed hosting a generic phishing campaign and is currently offline. The domain was registered on 21 February 2026 and resolves to the Cloudflare‑owned address 104.21.86.87, which belongs to ASN 13335 in the United States. DNS resolution is served by hans.ns.cloudflare.com and ullis.ns.cloudflare.com, confirming that the infrastructure is protected by Cloudflare’s edge network. The site presented the page title “ch-angenw.at” and employed HSTS and HTTP/3, indicating modern TLS configuration.

The TLS certificate was issued by Google Trust Services under the WE1 trust anchor, a legitimate certificate authority, demonstrating that the attackers obtained a valid certificate to improve credibility. Detection telemetry shows that 14 of 93 VirusTotal scanners flagged the domain, and it is listed on a single external security blocklist. PhishDestroy has also recorded the domain as blocked. No additional intelligence such as Safe Browsing, OTX, or registrar details is available, and the specific phishing lure or targeted brand has not been disclosed.

The combination of a recent registration, Cloudflare fronting, a valid Google‑issued certificate, and multi‑vendor detection suggests a purposeful attempt to evade basic URL reputation checks. Defenders should ensure that DNS filtering solutions block resolution to 104.21.86.87 for this hostname, add the domain to internal deny lists, and monitor the associated IP range for re‑use. Continuous re‑scanning of the domain after any future re‑appearance is advised, as the infrastructure could be repurposed for new campaigns. Organizations using URL filtering should also consider tightening policies for newly created domains that resolve to Cloudflare IPs, especially when paired with valid TLS certificates and early vendor detections.
