docs-zh[.]sui-book[.]com

Analysis of the domain docs-zh.sui-book.com indicates it was created on February 21, 2026, and is associated with a suspected crypto scam impersonating the Sui blockchain platform. The domain is registered through Alibaba Cloud Computing Ltd. d/b/a HiChina (www.net.cn) and currently resolves to the IP address 8.210.73.111, located in Hong Kong under AS45102 (Alibaba (US) Technology Co., Ltd.). Nameservers for the domain are dns27.hichina.com and dns28.hichina.com, consistent with Alibaba Cloud infrastructure. At the time of reporting, the domain lacks an SSL certificate, which is atypical for legitimate documentation or official brand sites, particularly in the cryptocurrency sector where security is a priority.

The page title, 'Sui 中文文档' (Sui Chinese Documentation), directly aligns with the brand impersonation of Sui, a known blockchain platform. The domain has been flagged by one security blocklist, PhishDestroy, though it is currently offline and not actively serving content. No detections were recorded by the 93 vendors that previously scanned the domain on VirusTotal, though the absence of detections does not confirm safety. The domain's classification as a crypto scam is based on its naming convention, impersonation of a blockchain brand, and registration patterns commonly observed in fraudulent schemes targeting cryptocurrency users.

Defenders should treat this domain as suspicious due to its brand impersonation, lack of SSL, and registration through a high-risk registrar often exploited for phishing. While the domain is offline, monitoring for reactivation is recommended, particularly for organizations or users associated with Sui or the broader cryptocurrency ecosystem. Further investigation into the hosting infrastructure and registrar history may reveal additional linked domains or campaigns.
