egppb2bportalten[.]ciamlogin[.]com

Analysis of egppb2bportalten.ciamlogin.com shows an active brand-impersonation campaign targeting Microsoft users. The site resolves to 20.190.151.9, an IP owned by Microsoft Corporation (AS8075) in the United States, and presents a valid TLS certificate issued to Microsoft Corporation by the Microsoft Azure RSA TLS Issuing CA 08. HSTS is enabled, and the HTTP response is a 302 redirect, indicating a potential credential‑harvesting flow. The domain was registered on February 03, 2023 through MarkMonitor, Inc., and uses Azure DNS name servers (ns1-36.azure-dns.com through ns4-36.azure-dns.org). Reputation services rate the site poorly: Scamadviser scores 16/100, Gridinsoft 0/100, and it appears on one security blocklist. VirusTotal reports 13 of 95 scanners flagging the domain, and it is already blocked by PhishDestroy. The page title "Sign in to your account" aligns with the declared scam type of a tech‑support impersonation. No additional page content has been observed, so the exact phishing mechanics remain unknown. Defenders should immediately add the domain and its resolving IP to deny‑list rules, monitor DNS queries for the associated Azure name servers, and enforce multi‑factor authentication for any Microsoft‑related services to mitigate credential compromise. Continuous re‑scanning of the host is advised to detect any payload changes.
