instagram-1ogin[.]duckdns[.]org

This domain is flagged as a high-risk credential harvesting phishing site specifically designed to impersonate Instagram login pages. Analysis indicates the infrastructure was established to deceive users into submitting account credentials through fraudulent login portals, a common tactic in account takeover campaigns. Infrastructure analysis reveals the domain instagram-1ogin.duckdns.org was registered through DuckDNS on June 08, 2026, and resolves to the IP address 216.198.79.1. The site appears on one security blocklist and is flagged by Google Safe Browsing as phishing. The SSL certificate is issued by Let's Encrypt (R12), a detail often exploited to lend false legitimacy. VirusTotal reports 22 out of 95 security vendors detect this domain as malicious, with the page title explicitly set to Instagram to enhance deception. The domain was subsequently taken offline, though residual risk remains for any cached or archived instances. Mitigation requires immediate action from network defenders and end users. Organizations should block the domain and its resolving IP (216.198.79.1) at perimeter security controls, including firewalls, DNS filters, and web proxies. Endpoint protection solutions should be updated to include this domain in phishing and malicious URL detection rules. Users who may have interacted with this site should be instructed to reset their credentials immediately, enable multi-factor authentication, and review account activity for unauthorized access. Security teams should monitor for related indicators, such as similar subdomains under duckdns.org or connections to the same IP, as threat actors frequently reuse infrastructure across campaigns.
