1fellype[.]github[.]io

This domain is flagged as a high-risk credential harvesting phishing site operating under the 1fellype.github.io subdomain. Analysis indicates the infrastructure is designed to mimic legitimate login portals, tricking users into submitting sensitive credentials such as usernames, passwords, and potentially multi-factor authentication codes. The threat actor appears to be leveraging GitHub Pages for hosting, a tactic increasingly observed in phishing campaigns due to its free availability and association with a trusted brand. Infrastructure analysis reveals the domain resolves to the IP address 185.199.108.153, a known GitHub Pages hosting endpoint. The domain is registered through GitHub, Inc., and uses a Let's Encrypt SSL certificate, providing a superficial layer of legitimacy. Detection metrics show 13 out of 95 security vendors on VirusTotal have flagged this domain as malicious. The domain appears on at least one security blocklist and has been blocked by independent detection systems. Gridinsoft assigns a trust score of 0/100, further corroborating its malicious nature. Despite these indicators, the domain remains active at the time of this report. Mitigation against this credential harvesting threat requires immediate action from both network defenders and end users. Network-level protections should include blocking the domain 1fellype.github.io and its resolving IP 185.199.108.153 at firewalls and web proxies. Security teams are advised to deploy indicators of compromise (IOCs) across endpoint detection and response (EDR) systems and security information and event management (SIEM) platforms. End users should be educated to scrutinize URLs, particularly those hosted on GitHub Pages, and verify the legitimacy of login portals before entering credentials. Multi-factor authentication (MFA) should be enforced wherever possible to mitigate the impact of credential theft. Organizations are recommended to conduct a thorough review of authentication logs for any interactions with this domain and reset credentials if exposure is suspected.
