zksync[.]beefyapps[.]sbs

Analysis of the domain zksync.beefyapps.sbs, created on October 24, 2025 and currently taken offline, shows multiple indicators of malicious activity targeting the zkSync brand. The domain resolves to the Cloudflare edge address 172.67.145.247, located in the United States and announced as AS13335 Cloudflare, Inc. Nameserver records point to brenna.ns.cloudflare.com and hassan.ns.cloudflare.com, confirming the use of Cloudflare’s DNS infrastructure. No SSL certificate is presented for the host, meaning HTTPS connections would be unavailable or insecure. The page title returned by the server reads "Access denied | zksync.beefyapps.sbs used Cloudflare to restrict access | zksync", which reflects a generic denial page rather than a legitimate zkSync service. The registrar listed for the domain is Dynadot LLC, a common registrar for both benign and malicious registrations.

Threat intelligence sources have classified the site as a brand‑impersonation campaign, explicitly stating it impersonates zkSync. Detection data show that the domain appears on one security blocklist and has been blocked by PhishDestroy. VirusTotal analysis recorded seven detections out of ninety‑five scanned security vendors, indicating a moderate level of consensus among scanning engines that the domain is malicious. Additionally, Gridinsoft assigned a trust score of 0 out of 100, reinforcing the assessment of high risk.

While the offline status limits immediate interaction, the combination of a recent creation date, lack of TLS, Cloudflare‑only hosting, and multiple detections suggests the domain was deployed to lure users into a fake zkSync experience, possibly to harvest credentials or redirect traffic. Uncertainties remain regarding the specific payload or credential‑harvesting mechanisms, as no detailed page content has been captured. Defenders should add the domain to internal blocklists, monitor DNS queries for the 172.67.145.
