mein-arcor-37d2a98-vdafne-43a9-adb3[.]vercel[.]app

Analysis of the domain mein-arcor-37d2a98-vdafne-43a9-adb3.vercel.app shows that it is currently offline and returns HTTP 451, indicating that the resource is unavailable for legal reasons. The site presented the page title “Vodafone E‑Mail & Cloud – Kundenportal”, suggesting an attempt to impersonate Vodafone’s portal. The domain is hosted on Vercel infrastructure; the TLS certificate is issued by Google Trust Services under the WR1 root, confirming that the connection was secured with a legitimate certificate chain despite the malicious intent. DNS resolution points to the IP address 64.29.17.195, which belongs to Amazon.com, Inc. (AS16509) and is geolocated in the United States. Nameserver information could not be retrieved (NS_NOT_FOUND).

The site employs HSTS, a security header that forces HTTPS, and Vercel technology fingerprints were detected. Multiple defensive feeds have flagged the domain. Google Safe Browsing categorises it as social engineering, and PhishDestroy has added it to its blocklist. VirusTotal records indicate that 16 of 95 scanned security vendors flagged the domain, reinforcing the suspicion of phishing activity. In addition, the domain appears on a single external security blocklist.

The registrar information shows that the domain was provisioned through Vercel Inc., a common platform for rapid deployment of short‑lived malicious sites. Given the combination of a convincing page title, a valid TLS certificate, and corroborating detections across several reputable sources, defenders should treat the domain as a high‑risk phishing vector. Recommendations include adding the domain and its resolved IP address to network‑level deny lists, updating email security gateways to block URLs containing the domain, and ensuring that endpoint protection solutions incorporate the VirusTotal detection data. Continuous monitoring of Vercel‑hosted assets for similar patterns is advised, as the platform is frequently abused for transient phishing campaigns.
