arubaid[.]sviluppo[.]host

The domain arubaid.sviluppo.host has been identified as a credential harvesting phishing resource targeting enterprise users. Analysis confirms the domain is designed to impersonate legitimate business hosting services, as evidenced by its page title, 'Host - Hosting sicuro e professionale dedicato alle imprese.' The domain is currently offline, though its infrastructure remains a documented threat vector.

Technical indicators reveal the domain was registered on May 12, 2017, through Tucows Domains Inc. and resolves to the IP address 81.31.158.9, geolocated in Italy under AS47242 (Host SpA). Detection metrics show the domain is flagged by 20 of 95 security vendors on VirusTotal, with additional listings on two security blocklists: PhishDestroy and PhishingDB. The SSL certificate, issued by Let's Encrypt (serial number E7), further aligns with observed phishing infrastructure patterns, where free certificates are frequently used to lend superficial legitimacy to malicious endpoints.

Given the domain's current offline status, the immediate threat of active credential harvesting is mitigated. However, the infrastructure remains a latent risk, particularly if reactivated or repurposed. Organizations are advised to proactively block the domain and its associated IP (81.31.158.9) at the network perimeter. Security teams should also monitor for similar domains registered under the sviluppo.host namespace or resolving to the same autonomous system. End-user training should emphasize verification of hosting service legitimacy, particularly for domains mimicking enterprise-grade providers.
