theofficial4me-ux[.]github[.]io

This domain, theofficial4me-ux.github.io, is identified as an active phishing resource specifically designed to impersonate Instagram's authentication portal. Analysis confirms it as a credential harvesting operation targeting users through fraudulent login interfaces. The domain remains operational as of the latest verification cycle. Infrastructure analysis reveals the domain is hosted on GitHub Pages, resolving to IP address 185.199.108.153 within the Fastly network (AS54113). Security telemetry indicates detection by 6 of 95 vendors on VirusTotal, with one confirmed blocklist entry. The page title explicitly displays 'instagram,' reinforcing its brand impersonation objective. The SSL certificate is issued by Let's Encrypt (R12), providing encrypted connections that may deceive users into perceiving legitimacy. No historical registration data is publicly available due to GitHub's hosting policies, though the subdomain structure suggests dynamic generation. Current assessment maintains a high-risk classification due to active credential theft operations. Organizations should implement immediate DNS-level blocking for theofficial4me-ux.github.io and its resolved IP address. Endpoint protection systems should be updated to recognize the domain's SSL certificate fingerprint and page title patterns. Users are advised to verify domain authenticity before entering credentials, particularly on pages with 'github.io' suffixes. Security teams should monitor for similar GitHub-hosted phishing domains using the 'theofficial' prefix pattern observed in this campaign.
