cupoatractivo-com-6v48[.]vercel[.]app

Analysis of the domain cupoatractivo-com-6v48.vercel.app shows a confirmed brand‑impersonation campaign targeting Bancolombia. The site resolves to IP address 64.29.17.67, which belongs to the Amazon.com, Inc. network (AS16509) and is geolocated in the United States. The domain is hosted on Vercel infrastructure, as indicated by the detected technologies Vercel and HSTS, and by the four Vercel‑provided nameservers (ns1‑ns4.vercel-dns-3.com). Registration records list Vercel Inc. as the registrar, with the domain creation date of 28 January 2020.

The HTTPS certificate is issued by Google Trust Services under the WR1 profile, suggesting a legitimate TLS termination but offering no protection against the underlying malicious content. HTTP responses return status code 451, and the page title retrieved from the live endpoint – "Solicitala en linea - Bancolombia" – directly references the targeted brand, reinforcing the impersonation intent. Trust metrics from Scamadviser assign a score of 1 / 100, indicating extreme untrustworthiness. The domain has been flagged by 18 of 95 security vendors on VirusTotal and appears on a single external blocklist.

PhishDestroy has already blocked the domain, and current observations list the site as offline. Defenders should immediately add the fully qualified domain name and its associated IP address to network and endpoint blocklists, enforce DNS filtering for the Vercel name‑server ranges, and monitor for any resurgence of the same infrastructure. Continuous threat‑intel feeds should be consulted for potential re‑registration or parallel campaigns employing similar naming patterns.
