smtp[.]ceramic33[.]ru

Analysis of smtp.ceramic33.ru indicates that the domain is currently offline, returning HTTP 502 Bad Gateway. The domain was registered on 30 September 2025 through the REGRU-RU registrar and resolves to IP 193.105.134.30, which is allocated to AS42237 w1n ltd in Sweden. No SSL certificate is presented for the host, meaning traffic would be unencrypted. The authoritative name servers are ns1.regerey.com and ns2.regerey.com.

Reputation services assign a Gridinsoft trust score of 0 out of 100, and the domain is listed on a single security blocklist. PhishDestroy has already blocked the domain. VirusTotal records show that four of ninety‑five scanners flagged the host, confirming malicious intent consistent with a generic phishing classification. The limited detection footprint and the lack of HTTPS suggest a low‑cost infrastructure, but the presence on multiple defensive feeds indicates active abuse.

Uncertainty remains regarding the exact phishing payload or targeted brands, as no page content beyond the generic “502 Bad Gateway” title is available. Defenders should continue to block the domain at the network perimeter, monitor DNS queries for the associated IP and name servers, and consider adding the IP to internal blacklists. Ongoing observation of the IP’s ASN activity is advised, as changes could signal relocation of the phishing infrastructure.
