docusign-dzz[.]gemeyal280-izkat-com-s-account[.]workers[.]dev

This domain is flagged as a high-risk credential phishing threat targeting users through fraudulent authentication portals. Analysis indicates the domain is designed to mimic legitimate services, specifically DocuSign, to deceive victims into submitting sensitive login credentials. The threat type is classified as credential theft, with a focus on harvesting usernames, passwords, and potentially multi-factor authentication codes. Infrastructure analysis reveals the domain was created on April 15, 2026, and remains active under Cloudflare Workers registration. It resolves to IP address 104.21.94.101, geolocated to California, with SSL certification provided by Let's Encrypt (serial E8). The domain is currently detected by 9 out of 95 security vendors on VirusTotal, appears on one security blocklist, and is blocked by PhishDestroy. The page title, 'Worker threw exception,' suggests a misconfigured or intentionally obfuscated phishing kit, potentially indicating an attempt to evade automated detection systems. Mitigation requires immediate blocking of the domain and its associated IP address (104.21.94.101) at the network perimeter. Organizations should implement email filtering rules to quarantine messages containing the domain or its subdomains. End-users should be educated on recognizing phishing indicators, such as unusual domain structures (e.g., 'gemeyal280-izkat-com-s-account'), and encouraged to verify sender authenticity before entering credentials. Multi-factor authentication (MFA) should be enforced to reduce the impact of credential theft. Security teams are advised to monitor for related infrastructure, such as similarly named Cloudflare Workers domains, and update detection signatures accordingly.
