jihinguku-sg[.]xyz

Analysis of jihinguku-sg.xyz, registered through PDR Ltd. d/b/a PublicDomainRegistry.com, shows a high‑risk brand‑impersonation campaign targeting the Argent brand. The domain was created on 26 November 2025 and is currently taken offline, but historical evidence indicates malicious activity. Infrastructure details reveal that the domain resolved to the IP address 172.67.177.3, hosted within the Cloudflare network (AS13335, United States). Nameservers listed as alexis.ns.cloudflare.com and amber.ns.cloudflare.com confirm the use of Cloudflare’s DNS service. No SSL certificate was observed, which is consistent with a lack of encrypted traffic for the site.

The page title returned by the server was the UUID‑style string “b06e4a93-0eea-4a0e-b70e-1d8803e2e6ea”, providing no meaningful content and suggesting a placeholder or obfuscation tactic. Detection data shows that 21 of 95 security vendors on VirusTotal flagged the domain, indicating a consensus of malicious classification. Google Safe Browsing flagged the domain for social engineering, and the Gridinsoft trust score was recorded at 0 out of 100, reflecting an extremely low reputation. The domain appears on one security blocklist and has been explicitly blocked by the PhishDestroy feed.

AlienVault OTX lists the domain in 16 separate threat‑intelligence pulses, reinforcing its association with malicious campaigns. While the site is no longer reachable, defenders should continue to monitor the associated IP range (172.67.177.0/24) for any re‑use, enforce outbound filtering for traffic to Cloudflare‑served domains lacking proper TLS, and update detection rules to include the specific page title string and the observed nameserver pair. Organizations using the Argent brand should treat any communications referencing jihinguku-sg.xyz as fraudulent and educate users about the social‑engineering warning.
