mail[.]fast-shipping[.]it

This domain, mail.fast-shipping.it, is actively impersonating Microsoft as part of a credential phishing operation. Analysis indicates the site presents a login page titled 'Sign in to your Microsoft Account,' a common tactic for harvesting user credentials. The domain was registered on March 6, 2026, through Aruba s.p.a. and remains operational as of July 12, 2026, resolving to IP address 3.255.68.192, hosted on Amazon.com, Inc. infrastructure (AS16509) in Ireland. The SSL certificate, issued by Sectigo Limited, is valid for public server authentication, which may lend a false sense of legitimacy to unsuspecting users. Security vendor detection on VirusTotal shows 11 out of 95 engines flagging the domain as malicious, while Gridinsoft assigns a trust score of 0 out of 100. The domain appears on at least one security blocklist, specifically PhishDestroy, and is classified as a tech support scam. Infrastructure analysis reveals the use of nameservers associated with Aruba s.p.a., including dns.technorail.com, dns2.technorail.com, dns3.arubadns.net, and dns4.arubadns.cz, which may be leveraged for redundancy or evasion purposes. Defenders should treat this domain as high-risk due to its active status, brand impersonation, and confirmed malicious classification. The HTTP 200 status indicates the phishing page is fully operational, and the recent registration date suggests it may not yet be widely blocked. Organizations are advised to implement immediate network-level blocking for mail.fast-shipping.it and its resolving IP address. Monitoring for related domains registered through Aruba s.p.a. or using similar nameserver patterns may help identify additional threats. Given the tech support scam classification, user awareness training should emphasize verifying login pages, particularly those requesting Microsoft account credentials.
