ostiumserver[.]pro
Resumo das evidências
Analysis of ostiumserver.pro shows that the domain was registered on 21 February 2026 through NiceNIC International Group Co., Limited and resolves to the Cloudflare‑owned IP 188.114.97.3 (AS13335, United States). The name servers mona.ns.cloudflare.com and coen.ns.cloudflare.com confirm that the site is fronted by Cloudflare, which also presents HSTS and HTTP/3 support. The SSL certificate is issued by Google Trust Services under the WE1 root, indicating a valid TLS configuration. An HTTP request returns status code 403 and the page title is “Just a moment…”, a typical Cloudflare challenge page rather than the final malicious payload. The domain appears on a single security blocklist and has been explicitly blocked by PhishDestroy.
On VirusTotal, three of ninety‑three scanners have flagged the host, reinforcing the suspicion of malicious use. Gridinsoft assigns a trust score of 0/100, the lowest possible rating. The available evidence points to a generic phishing operation, although the exact payload or credential‑harvesting page has not been captured. Uncertainty remains regarding the specific phishing kit, targeted brand, or the content delivered after the Cloudflare challenge.
Defenders should treat ostiumserver.pro as high‑risk: add the domain and its resolved IP to network‑level deny lists, monitor DNS queries for the associated Cloudflare name servers, and enforce URL filtering that blocks the domain. Continuous re‑scanning on VirusTotal and similar services is recommended to capture any changes in detection status. Logging of TLS handshakes can also help verify that the Google‑issued certificate remains unchanged, which may indicate a takeover attempt. Organizations should remain vigilant for outbound connections to the 188.114.97.3 address and consider isolating any internal hosts that have recently accessed the domain.
