challengersez[.]net

This investigation documents the domain challengersez.net, which was registered on January 03, 2026 through PDR Ltd. d/b/a PublicDomainRegistry.com. The site resolves to the Cloudflare‑owned address 172.67.202.214 (AS13335, United States). The SSL certificate presented is identified as WE1, indicating a generic TLS certificate typically issued by the hosting provider. The page title returned from the server is “Global | eSports and Gaming Community”, but the domain is listed as impersonating the Celer brand, matching the declared brand target of “celer”. The operation is classified as a brand‑impersonation scam and is currently marked offline.

Detection signals show that sixteen of ninety‑five VirusTotal scanners have flagged the domain, and the domain appears on one known security blocklist, where it is specifically blocked by PhishDestroy. Independent reputation testing assigns a Gridinsoft trust score of 0 out of 100, confirming a lack of legitimacy. No additional public threat‑intel feeds are referenced. Defenders should add challengersez.net to deny‑list or firewall rules, monitor outbound connections to the associated IP range and ASN, and enforce DNS filtering that includes the PhishDestroy blocklist entry.

Because the domain uses Cloudflare’s infrastructure, similar future impersonation attempts may reuse the same hosting provider; security teams should consider generic Cloudflare‑IP blocks only after assessing collateral impact. Continuous watch of new registrations that reference the “celer” keyword or that resolve to the same ASN is advised. Incident response teams should treat any credential or session data submitted to this domain as compromised, given the brand‑impersonation intent. The evidence set, anchored by the registration record, SSL certificate, detection counts, and blocklist status, supports an elevated risk rating and justifies immediate remediation actions.
