docusign[.]ostiumterms[.]com

Analysis as of July 23, 2026 identifies docusign.ostiumterms.com as an active malicious infrastructure used for generic phishing. The domain was registered on July 20, 2026 through Squarespace Domains LLC and resolves to the Cloudflare edge address 104.21.21.130, serviced by nameservers becky.ns.cloudflare.com and donald.ns.cloudflare.com. The recent creation date, combined with the use of a reputable CDN, is consistent with fast‑flux staging of phishing campaigns. The domain appears on a single security blocklist and is currently blocked by the PhishDestroy service.

VirusTotal scans show that four of ninety‑five security vendors have flagged the domain, indicating partial detection across the community. No additional context such as page title, SSL certificate details, or HTTP response codes is available in the supplied intelligence, leaving the exact content of the hosted site unverified. However, the subdomain “docusign” strongly suggests an attempt to impersonate the DocuSign brand, a common target for credential‑harvesting schemes.

Defenders should add the domain and its resolved IP address to outbound filtering rules, monitor DNS queries for the associated Cloudflare nameservers, and consider immediate sink‑holing or sink‑routing of traffic to prevent credential capture. Continuous re‑scanning with multi‑engine services is recommended to capture any change in detection status, and any observed malicious payloads should be shared with threat‑intel platforms to improve collective detection. Given the recent registration and active blocklist status, the risk rating remains high until the infrastructure is fully mitigated.
