teomsapp[.]top

On 24 September 2025 the domain www.teomsapp.top was registered through Gname.com Pte. Ltd. The registrar information and the use of the shared DNS providers a1.share-dns.com and b1.share-dns.net are consistent with rapid‑deployment phishing infrastructure. DNS resolution points to IP 172.245.67.31, which is announced by AS36352 (HostPapa) and geolocated to the United States. An SSL certificate covering 172.245.67.50 is present, indicating a mismatched certificate that does not correspond to the domain name, a typical indicator of fraudulent sites. The website’s page title reads “Teams官网 - Teams中文版”, directly referencing Microsoft Teams in Chinese, and the listed brand target is Microsoft, confirming a brand‑impersonation campaign.

VirusTotal has recorded a single positive detection out of 95 scanning engines, and the domain is listed on one public blocklist, currently blocked by PhishDestroy. Gridinsoft assigns a trust score of 0 / 100, reinforcing the malicious classification. The risk level is elevated and the status is reported as offline, suggesting that the site has been taken down or is no longer reachable. What remains unknown includes the exact payload delivered to victims, any credential‑harvesting form, and whether the domain was actively used before takedown.

No additional intelligence such as OTX tags, Safe Browsing verdicts, or external analysis links were supplied. Defenders should add www.teomsapp.top to internal block lists, monitor the hosting ASN (AS36352) for further suspicious domains, and enforce strict URL filtering for any references to Microsoft Teams login pages. Email security gateways should be tuned to flag messages containing the domain or the Chinese‑language Teams title. Continuous observation of the registrar Gname.com Pte. Ltd. and the shared DNS infrastructure may reveal future campaigns that reuse the same infrastructure.
