telegramauthh[.]online

As of the report date, July 23, 2026, the domain telegramauthh.online has been taken offline. This domain was registered through REGRU-RU on June 24, 2025, and was known to impersonate the brand Telegram, likely engaging in social media phishing activities. The domain employed Cloudflare nameservers, specifically daniella.ns.cloudflare.com and skip.ns.cloudflare.com, which could indicate attempts to obfuscate the true hosting location or add a layer of security. However, the absence of an SSL certificate presents a red flag, as legitimate services typically secure their websites with valid certificates.

The domain's IP address, 149.154.167.99, is located in the Netherlands and is associated with the AS62041, Telegram Messenger Inc. This association is unusual and may suggest that the domain was part of a sophisticated impersonation effort. The Gridinsoft trust score for telegramauthh.online is 0 out of 100, indicating a very high level of suspicion. The domain was also flagged by PhishDestroy and appears on one security blocklist, further corroborating the elevated risk level. While the domain is currently offline, it is important for defenders to remain vigilant.

The page title 'Telegram Messenger' suggests that the domain was designed to mimic a legitimate Telegram service, potentially leading users to enter sensitive information. Given the available evidence, defenders should ensure that any previous interactions with this domain are reviewed for potential breaches and that users are educated on the risks of phishing and the importance of verifying the authenticity of websites, especially those purporting to be official Telegram services. Regular monitoring and updating of security measures are recommended to prevent future similar threats.
