m[.]siaiba[.]cc

Analysis of the domain m.siaiba.cc, observed on July 22 2026, shows that it was registered on March 10 2026 through Gname.com Pte. Ltd. The authoritative name servers are kolton.ns.cloudflare.com and sky.ns.cloudflare.com, indicating use of Cloudflare’s DNS service. DNS resolution points to the IP address 172.67.141.209, which belongs to Cloudflare, Inc. (ASN 13335) and is geolocated in the United States. The TLS certificate presented by the host is issued by Google Trust Services under the WE1 certificate authority, which is typical for Cloudflare‑proxied sites. An HTTP request to the root URL returns a 403 status code, suggesting that the server is configured to deny direct access, a behavior sometimes observed in malicious infrastructure that relies on redirection or hidden content.

The page title returned from the site is “Sia Funds”, a name that has been associated with phishing campaigns targeting financial services. The domain has been added to three independent security blocklists and is actively blocked by anti‑phishing products such as PhishDestroy, MetaMask, and SEAL. VirusTotal scans show that three of ninety‑five security vendors flagged the domain, providing additional corroboration of malicious intent. Current operational status is listed as offline, which may be the result of takedown actions or a temporary shutdown by the operators.

Nonetheless, the combination of recent registration, Cloudflare hosting, a valid SSL certificate, a 403 response, and inclusion on multiple blocklists establishes a high confidence that the domain was being used for phishing. Defenders should continue to block the domain at DNS and proxy layers, monitor the associated IP address for any re‑use, and consider adding the host to internal threat intelligence feeds. Ongoing observation of the registrar Gname.com Pte. Ltd. and the Cloudflare name servers may reveal further related infrastructure.
