docusign-signature[.]github[.]io

PhishDestroy identifies the domain docusign-signature.github.io as an active generic phishing infrastructure leveraging the DocuSign brand to deceive users into disclosing sensitive information. This domain impersonates DocuSign's signature verification portal, a common tactic in credential harvesting campaigns. The infrastructure relies on a drainer kit designed to mimic legitimate DocuSign workflows, tricking victims into inputting their login credentials or payment details. Technical analysis confirms the presence of obfuscated JavaScript within the landing page to capture user input and exfiltrate data to attacker-controlled servers.

This domain was flagged by 18 out of 95 VirusTotal security vendors, indicating widespread detection but insufficient blocking by default configurations. Registered through GitHub, Inc., the domain resolves to the IP address 185.199.108.153 and utilizes a Let's Encrypt SSL certificate for authenticity. The domain has been active long enough to be included on 2 security blocklists, including OpenPhish and OISD blocklists, underscoring its malicious reputation. While the exact creation date is not provided, the presence on multiple blocklists suggests a prolonged operational period.

Current status of docusign-signature.github.io remains active, posing an elevated risk to unsuspecting users. Immediate response actions include blocking the domain at the network perimeter and updating endpoint detection rules to quarantine associated IP traffic. Despite these measures, the domain continues to evade complete takedown, likely due to GitHub's hosting policies for Pages services. Remaining risk is elevated, particularly for organizations with lax email filtering or users unfamiliar with DocuSign's official domains. PhishDestroy recommends heightened scrutiny for emails referencing DocuSign signatures and immediate reporting of any suspicious activity to security teams. Users should verify sender domains and avoid clicking on embedded links in unsolicited messages.
