cupchallengers[.]world

Analysis of cupchallengers.world shows that the domain was registered on February 21, 2026 through PDR Ltd. d/b/a PublicDomainRegistry.com and is presently taken offline. The authoritative name servers are dns1.regway.com, dns2.regway.com, dns3.regway.com and dns4.regway.com, indicating the use of RegWay's DNS infrastructure. DNS resolution points to the IPv4 address 109.120.137.102, which is allocated to H2nexus LTD in Germany.

The hosting entity has been observed in multiple threat‑intel feeds; AlienVault OTX lists the domain in fifteen separate pulses, and the domain appears on one security blocklist. Independent anti‑phishing service PhishDestroy also blocks the domain. VirusTotal scans report that fifteen out of ninety‑three security vendors flagged the domain as malicious, reinforcing the suspicion of illicit activity despite the current offline status.

The combined evidence—recent creation date, registrar choice, German‑based hosting, multiple OTX mentions, blocklist presence, and multi‑vendor detections—suggests that the domain was employed for a generic phishing campaign. Defenders should continue to enforce outbound filtering for connections to 109.120.137.102, ensure that any email or web traffic referencing cupchallengers.world is blocked at the perimeter, and monitor for any resurgence of the domain or its associated IP range. Given the domain’s recent creation and rapid takedown, threat actors may attempt to re‑register a similar name or shift to adjacent IP space; therefore, threat‑intel teams should add the domain and its IP to watchlists and consider proactive domain‑fronting detection rules.
