updex[.]cc

updex.cc is currently offline but historical data indicate it was deployed as a counterfeit cryptocurrency exchange targeting users of the Ethereum brand. The domain was registered on 31 May 2026 through Cloud DNS Ltd and is hosted on the IP address 138.226.237.221, which belongs to AS205775 NEON CORE NETWORK LLC and is geolocated in Germany. Authoritative name servers pns71.cloudns.net, pns72.cloudns.com, pns73.cloudns.net and pns74.cloudns.uk were observed, and the site presented a valid TLS certificate issued by Let’s Encrypt (certificate identifier YE1). The page title advertised “Crypto Exchange | Buy & Sell Bitcoin, Ethereum & more”, directly referencing the targeted brand and confirming the fake‑exchange classification.

Detection telemetry shows that 11 of 91 security vendors on VirusTotal flagged the domain, and it appears on a single external blocklist. PhishDestroy has listed the domain as blocked, and Gridinsoft assigned a trust score of 1 out of 100, reflecting a high confidence of malicious intent. No additional public intelligence (e.g., OTX, Safe Browsing) was provided in the source data. The available evidence confirms that updex.cc was used for brand impersonation and likely to harvest credentials or funds from unsuspecting cryptocurrency traders.

Because the site is no longer reachable, immediate mitigation focuses on preventative controls: adding the domain and its resolving IP to network‑level deny lists, updating intrusion‑detection signatures with the observed name‑server set and TLS fingerprint, and monitoring for re‑registration attempts. Analysts should also watch for similar domains that reuse the same hosting ASN or certificate authority, as the infrastructure suggests a reusable template. Continuous collection of passive DNS and certificate transparency logs is recommended to capture any future re‑appearance of the service.
