challengesez[.]pro

The domain challengesez.pro was registered on December 21, 2025 through PDR Ltd. d/b/a PublicDomainRegistry.com and currently resolves to the IPv4 address 91.214.78.99, which is hosted in the Netherlands under AS205775 (NEON CORE NETWORK LLC). No SSL certificate is presented for the site, indicating that any traffic would be unencrypted. The authoritative name servers are dns1.regway.com, dns2.regway.com, dns3.regway.com, and dns4.regway.com, all of which are typical of low‑cost registrars. The page title returned from the live host before it was taken offline reads “Global | eSports and Gaming Community,” a generic title that does not reference the targeted brand.

The domain is classified as a brand‑impersonation campaign targeting the brand celer, and it has been flagged by 16 of 93 security vendors on VirusTotal. It appears on a single public blocklist and is actively blocked by the PhishDestroy service. Gridinsoft assigns a trust score of 0 out of 100, reinforcing the malicious assessment. AlienVault OTX lists the domain in three separate threat‑intel pulses, providing additional corroboration of its abuse.

The site’s current status is offline, but the infrastructure components—hosting provider, registrar, and name‑server configuration—remain observable. Defenders should add the IP 91.214.78.99 and the domain challengesez.pro to outbound and inbound filtering rules, monitor for any future DNS resolution changes, and consider sharing the indicators with threat‑sharing communities. Continuous observation of the registrar and hosting ASN is advised, as the actors could redeploy the domain or shift to a new host while retaining the same brand‑impersonation tactics.
