bitcloak[.]online

Analysis indicates that the domain bitcloak.online was registered on February 21 2026 through NiceNIC International Group Co., Limited. The authoritative nameservers are brodie.ns.cloudflare.com and sara.ns.cloudflare.com, and the domain resolves to IP 104.21.53.42, which belongs to Cloudflare, Inc. (AS13335) and is geolocated in the United States. An HTTPS certificate issued by Google Trust Services under the WE1 root validates the domain, confirming the use of a legitimate certificate authority despite the malicious intent. HTTP requests receive a 301 redirect, and the page title observed is “BitCloak Bitcoin Mixer”, indicating a crypto‑mixing service that impersonates the Bitcoin brand. The underlying stack reports Ubuntu with Nginx serving a site built on Bootstrap.

The domain is listed on the PhishDestroy blocklist and appears on one additional security blocklist, confirming active detection by at least one external repository. VirusTotal scans show that 2 of 93 security vendors have flagged the site, reinforcing the malicious classification. The Gridinsoft trust score of 0 out of 100 provides further quantitative evidence of high risk. The risk level is designated as high, and the current status remains active. Defenders should treat bitcloak.online as a confirmed high‑risk crypto‑scam infrastructure.

Immediate mitigation steps include adding the domain and its resolving IP 104.21.53.42 to network deny lists, updating proxy and firewall rules to block traffic to both the domain and the associated Cloudflare IP range if feasible, and ensuring endpoint protection solutions are configured to recognize the two vendor detections reported by VirusTotal. Continuous monitoring of the registrar NiceNIC International Group Co., Limited for any new registrations that reuse the same nameservers or similar naming patterns is advised, as this may indicate a broader campaign.
