prologin[.]biz

Analysis of prologin.biz indicates an active credential phishing domain registered on February 21, 2026, through NiceNIC International Group Co., Limited. The domain currently resolves to IP 185.178.208.160, hosted on AS57724 (DDOS-GUARD LTD) in Russia, with DDoS-Guard mitigation technology detected. The SSL certificate is issued by Let's Encrypt (R13), a common choice for both legitimate and malicious infrastructure. As of July 24, 2026, the domain returns an HTTP 503 status, suggesting either temporary unavailability or deliberate evasion of automated scans.

The page title, 'prologin.biz,' provides no explicit brand targeting or kit identification, and no specific phishing kit or targeted service is confirmed in available intelligence. The domain appears on one security blocklist (PhishDestroy) and holds a Gridinsoft trust score of 0/100, reinforcing its high-risk classification. VirusTotal records indicate three detections from 93 security vendors, though the absence of additional context limits definitive conclusions about the nature of these flags. Nameservers ns3.my-ndns.com and ns4.my-ndns.com are associated with the domain, though their historical or current involvement in other malicious activity remains unconfirmed.

Defenders should treat prologin.biz as a high-risk credential phishing domain. Recommended actions include blocking the domain and its resolving IP at network and endpoint levels, monitoring for related infrastructure (e.g., subdomains or newly registered lookalike domains), and reviewing logs for connections to 185.178.208.160 or associated nameservers. Further analysis of the phishing kit or targeted brand is not possible with current evidence, and the domain's operational status may fluctuate due to the observed HTTP 503 response.
