Analysis of the domain spx30b.icu, observed on 30 July 2026, indicates that it is actively being used in a generic phishing operation. The domain was registered on 15 July 2026 through NICENIC INTERNATIONAL GROUP CO., LIMITED and is hosted on the IP address 172.67.151.48, which is associated with Cloudflare's global edge network. Both authoritative name servers—gordon.ns.cloudflare.com and heidi.ns.cloudflare.com—are Cloudflare‑provided, suggesting the attacker is leveraging Cloudflare’s CDN and DNS services to obscure the true origin of the traffic. VirusTotal records show that the domain has been submitted to the service and examined by 91 antivirus engines; at the time of analysis none of the engines reported a detection.
This lack of detections does not constitute evidence of benign intent, but it does indicate that the payload or hosting page has not yet been fingerprinted by the scanners. The domain appears on the PhishDestroy blocklist, confirming that at least one external threat‑intelligence platform has classified it as malicious. No additional blocklists or public safe‑browsing feeds currently list the domain. Publicly available information about the TLS certificate, HTTP response codes, page title, or any referenced malicious payloads has not been disclosed, leaving those vectors unverified.
Defenders should proactively block any traffic to spx30b.icu at the network perimeter and add the domain to internal URL filtering policies. Continuous monitoring of the associated IP address and Cloudflare name servers for changes in behavior is advised. Re‑checking VirusTotal and other sandbox services on a regular cadence can capture future detections. Organizations that receive suspicious emails referencing the domain should treat them as phishing attempts and instruct users not to disclose credentials.
