1548789459[.]github[.]io

This domain, 1548789459.github.io, is actively flagged as a high-risk phishing site hosted on GitHub Pages infrastructure. Analysis reveals it resolves to the IP address 185.199.108.153, a known GitHub Pages hosting endpoint, which aligns with its registration through GitHub, Inc. The domain currently lacks configured nameservers, a deviation from standard GitHub Pages deployments, which may indicate deliberate misconfiguration or an attempt to evade detection. As of July 28, 2026, the domain remains active and is blocked by PhishDestroy, with six out of ninety-one security vendors on VirusTotal flagging it as malicious. The absence of additional blocklist entries or public threat intelligence suggests this campaign may be relatively new or targeted, limiting broader detection coverage.

Infrastructure analysis indicates the domain leverages GitHub’s free hosting service, a common tactic for phishing operations due to its low cost and perceived legitimacy. The lack of nameservers is atypical and may hinder automated takedown efforts or DNS-based filtering. No specific brand target, phishing kit, or scam category has been identified in available evidence, and the exact content of the site remains unanalyzed.

Defenders should treat this domain as a confirmed phishing threat, particularly given its active status and detection by multiple security vendors. Organizations are advised to block the domain and its resolving IP at the network level, monitor for related GitHub Pages subdomains, and report the abuse to GitHub’s security team for expedited removal. Further investigation into the domain’s HTTP response headers, SSL certificate details, and any embedded scripts may provide additional indicators of compromise or campaign attribution.
