telettsh[.]co

Analysis of telettsh.co indicates a high‑risk brand‑impersonation campaign targeting Telegram users. The domain was registered on June 9 2026 through NICENIC INTERNATIONAL GROUP CO., LIMITED and resolves to IP 27.124.47.186, which is allocated to AS152194 (CTG Server Limited) in Hong Kong. DNS is served by ns3.my-ndns.com and ns4.my-ndns.com. An HTTP request returns status 200 and the page title is "Telegram Web," suggesting an attempt to lure victims with a familiar service name. The presented SSL certificate lists the subject "Telegram / *.local," a mismatch that further signals malicious intent. The domain appears in one AlienVault OTX pulse and is currently listed on a single security blocklist; PhishDestroy has already blocked it. VirusTotal scans show 11 of 91 security vendors flagging the domain, reinforcing the suspicion of malicious activity. While the exact content of the site has not been examined, the observed indicators—brand‑specific title, mismatched certificate, recent registration, and multiple detections—confirm an active impersonation operation. Defenders should immediately block telettsh.co and its resolved IP at network perimeters, add the domain and IP to threat intelligence feeds, and monitor for DNS queries or outbound connections to the host. User education campaigns should warn against unsolicited links claiming to lead to "Telegram Web" and encourage verification of TLS certificates before entering credentials. Continuous re‑evaluation is advised in case the site evolves or additional samples become available.
