“Sierra Courier”
증거 요약
Analysis conducted on July 24, 2026 identifies sierra-app.navideliver.com as a high‑confidence generic phishing candidate. The domain was registered through Network Solutions, LLC on July 21, 2025 and resolves to the Amazon Web Services IP address 3.99.129.248, which is announced by ASN AS16509 (Amazon.com, Inc.) and located in the United States (California). No TLS certificate is presented, indicating an unencrypted HTTP service that was observed to be taken offline at the time of review. The authoritative nameservers listed are ns1.domain.com and ns2.domain.com, providing no further insight into the hosting infrastructure.
The only visible page element is the title "Sierra Courier," which does not disclose the target brand or any additional content. Gridinsoft assigns a trust score of 0 out of 100, and the domain appears on a single security blocklist. VirusTotal reports that 14 of 95 scanning engines flag the domain as malicious, and the phishing‑focused blocklist PhishDestroy has explicitly blocked it. These detections collectively reinforce the malicious assessment.
Uncertainty remains around the exact phishing kit or the specific credential‑harvesting workflow, as no page capture or content analysis is available. Defenders should treat the domain as hostile: add the host to network denial lists, monitor DNS queries for the domain and its associated IP range, and enforce HTTPS‑only policies to mitigate potential downgrade attempts. Continuous re‑scanning of the domain is recommended should it come back online, as the current offline status does not guarantee future inactivity.
