Infrastructure analysis reveals that www.qfsquantumsecurity.com was registered through Dynadot Inc on February 03, 2026. The domain resolves to the IP address 198.251.81.49 and uses a Let's Encrypt SSL certificate. It has been flagged by 15 out of 95 security vendors on VirusTotal, indicating a moderate level of suspicion among the security community.
