As of July 17, 2026, the domain remains operational, resolving to IP address 103.52.114.215. Infrastructure analysis reveals Cloudflare nameservers (aldo.ns.cloudflare.com, pat.ns.cloudflare.com), a common tactic to obscure hosting origins and evade takedowns.

The subdomain 'rumahsakit' translates to 'hospital' in Indonesian, implying potential impersonation of medical or healthcare portals, though the exact content or targeted brand remains unconfirmed. No specific phishing kit or payload has been attributed to this domain in available intelligence. Defenders should treat this domain as high-risk due to its active status, Cloudflare-backed infrastructure, and partial vendor detection. Recommended actions include blocking the domain and IP at perimeter controls, monitoring for connections from internal hosts, and reviewing logs for interactions with 103.52.114.215 or associated Cloudflare nameservers. Further investigation is required to determine the precise phishing lure or credential-harvesting mechanism employed.
