kucoini77[.]com

Analysis of kucoini77.com indicates that the domain is being used to impersonate the cryptocurrency exchange KuCoin in a crypto‑scam campaign. The domain was registered on March 31, 2025 through Gname.com Pte. Ltd., and it resolves to the IPv4 address 103.87.242.102, which is allocated to AS135581 (ONL‑HK) in Hong Kong. The hosting infrastructure has been flagged by a single security blocklist and is actively blocked by the PhishDestroy service, confirming that the site is recognized as malicious by at least one reputable sinkhole. VirusTotal scans show that 12 out of 93 antivirus and URL‑reputation engines flagged the domain, providing additional independent confirmation of its malicious nature.

The SSL certificate presented by the site is identified as rating R10, a low trust indicator often associated with fraudulent sites. Gridinsoft’s trust scoring system assigns a score of 0 out of 100, reinforcing the assessment that the domain lacks any legitimate reputation. The site’s current HTTP status is offline, suggesting that the operators have taken it down, possibly in response to takedown actions, but the underlying infrastructure and registration details remain unchanged.

Defenders should continue to block the IP address 103.87.242.102 and the domain name in DNS filtering solutions, monitor for any re‑registration attempts, and incorporate the domain’s indicators into threat‑intel feeds. Organizations using KuCoin services should alert users to the existence of this impersonation attempt and advise verification of URLs before entering credentials. Ongoing observation of the registrar Gname.com Pte. Ltd. for similar patterns is recommended, as it has been used for other malicious registrations in the past.
