cistyportdex[.]com

The domain cistyportdex.com was registered on 21 February 2026 through Gransy, s.r.o. and is currently listed as offline. DNS resolution points to the IPv6 address 2a06:98c1:3121::3 and uses Cloudflare nameservers dax.ns.cloudflare.com and may.ns.cloudflare.com, placing the hosting infrastructure within AS13335 Cloudflare, United States. No SSL certificate is observed for the site, indicating the absence of HTTPS protection.

The page title retrieved during a brief crawl reads "Čistý Portdex - Oficiální platforma | AI‑Trading 2025 | Více než 10 000 hodnocení", which aligns with a social‑media phishing campaign that claims to impersonate the brand argent. Gridinsoft assigns a trust score of 0 out of 100, and the domain appears on one security blocklist, confirming its malicious reputation. AlienVault OTX records the domain in a single threat‑intelligence pulse, and PhishDestroy actively blocks it. VirusTotal analysis shows that two of ninety‑three security vendors flagged the domain, reinforcing the suspicion despite the low detection count.

The combination of brand impersonation, a fabricated AI‑trading narrative, and the lack of TLS suggests a deliberate attempt to lure victims via social‑media links. Uncertainty remains regarding the exact payload or credential‑harvesting mechanisms because the site content has not been fully examined. Defenders should add cistyportdex.com to URL filtering and DNS block lists, monitor for related Cloudflare‑hosted IP activity, and enforce strict TLS inspection for outbound traffic to this address. Continuous threat‑intel feeds should be consulted for any updates to detection signatures or additional indicators of compromise.
