harshu639[.]github[.]io

This domain, harshu639.github.io, is identified as an active credential theft operation. Analysis indicates the infrastructure is designed to harvest usernames, passwords, and session tokens through deceptive login portals or cloned authentication pages. The threat leverages legitimate hosting services to evade initial detection, making it particularly effective against users who may not scrutinize the domain closely. Evidence supporting this assessment includes detection by 12 out of 95 security vendors on VirusTotal, with the domain appearing on one security blocklist. The SSL certificate is issued by Let's Encrypt (R12), and the domain resolves to the IP address 185.199.110.153, which is associated with GitHub, Inc. in the United States. Despite the page title displaying 'Site not found · GitHub Pages,' the domain was created on April 15, 2026, and remains active, suggesting it may serve malicious content intermittently or redirect to other compromised endpoints. Users who have visited harshu639.github.io should immediately revoke any active sessions associated with the site, reset passwords for accounts accessed during the visit, and enable multi-factor authentication where available. Monitor financial and email accounts for unauthorized activity, as stolen credentials may be exploited across multiple platforms. If login credentials were entered, assume they are compromised and avoid reusing them on other services. Network administrators should block the domain and its resolving IP address to prevent further exposure within their environments.
