uspto-lawoffice[.]us

Analysis of the domain uspto-lawoffice.us indicates active credential phishing infrastructure as of July 12, 2026. The domain resolves to IP address 34.174.73.152, hosted on autonomous system AS396982 (Google LLC) in the United States. Infrastructure analysis reveals the use of Nginx web server software and SiteGround hosting technologies, alongside a Let's Encrypt SSL certificate issued under the YR2 policy. The domain is currently flagged by three security blocklists, including PhishDestroy, MetaMask, and SEAL, and appears in one threat intelligence pulse on AlienVault OTX. Gridinsoft assigns a trust score of 0/100, reflecting high-risk classification. The domain's HTTP response returns a 403 status code, and the page title 'Under construction - Awesome site in the making!' suggests either placeholder content or an attempt to evade detection. While only three of ninety-one security vendors on VirusTotal flag the domain, this limited detection does not preclude malicious intent, particularly given the domain's presence on multiple blocklists and its association with credential phishing activity. The registrar and registration details remain unconfirmed, but the combination of hosting on a major cloud provider, low detection rates, and blocklist inclusion is consistent with tactics used to prolong operational lifespan. Defenders should treat uspto-lawoffice.us as an active threat, particularly in environments where credential harvesting poses significant risk. Monitoring for connections to 34.174.73.152 and associated domains, as well as implementing blocklist-based restrictions, is recommended. Further analysis of the domain's content and redirect behavior is necessary to determine the full scope of its phishing campaign, though current evidence supports immediate mitigation measures.
