coinbasetnk[.]com

Analysis of coinbasetnk.com indicates a high probability of malicious activity targeting the Coinbase brand. The domain resolves to the IP address 211.217.162.112, which is registered to Korea Telecom (AS4766) and physically located in South Korea. No TLS certificate is presented, meaning the site is served over plain HTTP, which reduces the perceived legitimacy of any credential‑collection page. The authoritative nameservers for the domain are ns1.sectigoweb.com through ns4.sectigoweb.com, a set of servers commonly observed in other fraudulent infrastructure. The site’s only visible attribute is the page title "Welcome to your SWAG instance," which does not reference Coinbase and suggests a generic placeholder page rather than a brand‑specific login portal.

The domain is catalogued as a crypto‑related scam and is explicitly listed as impersonating Coinbase. Detection data shows that eight of ninety‑five security vendors on VirusTotal flagged the domain, and it appears on at least one public security blocklist. Additionally, the domain has been blocked by the PhishDestroy service, reinforcing the consensus that it is associated with phishing or credential‑harvesting activity. Registration details reveal that the domain was created on 25 March 2022 through PublicDomainRegistry.com (operated by PDR Ltd.), a registrar that is frequently used for disposable or malicious domains.

Current status is offline, which may indicate that the operators have withdrawn the site or are rotating infrastructure. Uncertainty remains regarding the exact content that was delivered before takedown, as no visual or functional analysis is available beyond the page title. Defenders should continue to block the domain at network perimeter, update DNS sinkhole lists with the associated IP and nameserver ranges, and monitor for any re‑registration attempts or similar domains using the same nameserver set.
