yupp[.]app-0x[.]com

Analysis of the domain yupp.app-0x.com indicates that it was registered on 21 February 2026 and is presently taken offline. DNS resolution points to the address 104.21.21.235, which is owned by Cloudflare, Inc. (AS13335) and geolocates to the United States. The site presented a page titled “Yupp | Login”, consistent with the classified scam type of credential phishing. Scanning on VirusTotal returned detections from two of ninety‑three security vendors, confirming that at least a minority of engines consider the domain malicious.

Independent reputation services have assigned a Gridinsoft trust score of zero out of one hundred, and the domain appears on two public blocklists. Additional blocklist providers PhishDestroy and ScamSniffer have explicitly listed the domain as blocked. The SSL certificate associated with the host is identified as “WE1”, which does not correspond to a recognized trusted authority and further lowers confidence in the site’s legitimacy. While the available data confirms malicious intent, the offline status prevents real‑time verification of the payload or credential‑harvesting mechanisms.

Consequently, defenders should continue to block the domain at network perimeter and DNS layers, monitor for any resurgence of the host, and correlate any login attempts to the Yupp brand with threat‑intel feeds. Ongoing observation of the IP address 104.21.21.235 is advised, as Cloudflare may be used as an anonymizing front for other malicious campaigns. The limited detection coverage suggests that additional sandbox or endpoint analysis could surface further indicators if the site reappears.
