증거 요약
Analysis of the domain s.teams-ei.com indicates it was actively involved in a brand impersonation campaign targeting Microsoft. The domain, registered on May 9, 2026, through REG.RU LLC, resolved to the IP address 172.67.147.226, which is part of Cloudflare's network (AS13335) located in the United States. Infrastructure analysis reveals the use of Cloudflare nameservers (marjory.ns.cloudflare.com and yadiel.ns.cloudflare.com), a common tactic to obscure hosting origins and evade immediate takedowns. The domain was assigned a Let's Encrypt SSL certificate (identifier E7), suggesting an attempt to appear legitimate to potential victims.
Security vendor detections on VirusTotal show that 14 out of 91 engines flagged the domain as malicious, a moderate but notable level of consensus. The domain appears on at least one security blocklist, specifically PhishDestroy, and was assigned a Gridinsoft trust score of 0/100, reinforcing its classification as high-risk. While the domain is currently offline, its association with a known phishing kit labeled 'Steam Phishing' suggests it may have been part of a broader campaign leveraging gaming or account compromise themes, though the exact content served remains unconfirmed. Defenders should treat this domain as part of a Microsoft-branded phishing operation.
The use of Cloudflare infrastructure and a recently registered domain aligns with common phishing tactics. Organizations are advised to block the domain at the DNS level and monitor for related indicators, including the IP address 172.67.147.226 and associated SSL certificate. Given the domain's offline status, further analysis of cached or archived content may provide additional context, though no such data is currently available in the provided intelligence.
