caiocosta004[.]github[.]io

The domain caiocosta004.github.io is flagged as an active generic phishing infrastructure with an elevated risk rating as of July 29, 2026. Infrastructure analysis shows that the domain resolves to the IP address 185.199.108.153, which belongs to the GitHub Pages hosting service. Registration details indicate that the domain was created through GitHub, Inc., and no authoritative nameserver records were returned (NS_NOT_FOUND).

The site has been blocked by the PhishDestroy sinkhole and appears on one external security blocklist, demonstrating that at least one reputable anti‑phishing feed has identified it as malicious. VirusTotal scanning reports that 14 of 91 security vendors flagged the domain, providing additional corroboration of its malicious nature. No public SSL certificate information, HTTP response codes, or page title metadata are currently available, limiting the observable surface to hosting and detection data.

Defenders should continue to block the domain at network perimeters, update DNS sinkhole lists with the observed IP, and monitor for any new resolutions or registration changes. Because the domain is hosted on a legitimate cloud platform, threat actors may exploit the trusted reputation of GitHub Pages to evade simple URL‑based filters, so heuristic and reputation‑based controls are recommended. Ongoing surveillance is advised to capture any future content changes or additional detection signals that could refine the threat profile.
