duolingo-ai[.]next-cryptolist[.]net

This domain, duolingo-ai.next-cryptolist.net, is a fake site designed to impersonate the popular language-learning brand Duolingo. By mimicking Duolingo's appearance and using a similar subdomain, it tricks visitors into entering their login credentials or personal information. This is a classic phishing attack that could lead to account theft or identity fraud. The site was recently created and has already been taken offline, but similar domains may still be active.

PhishDestroy's analysis shows that this domain was flagged by 2 out of 95 security vendors on VirusTotal, indicating a low but notable detection rate. It was registered on April 11, 2026, through Key-Systems GmbH, a German registrar. The site was hosted on Cloudflare (IP 104.21.64.107) with an SSL certificate from Google Trust Services, which unfortunately made it appear legitimate to some users. It currently appears on one security blocklist and has been taken offline, but the threat remains for any copycat domains.

If you visited this domain, you should immediately change your Duolingo password and any other accounts where you used the same credentials. Run a full antivirus scan on your device and monitor your accounts for suspicious activity. Report the domain to your email provider or security team. Stay vigilant against phishing by always checking the URL before entering sensitive information and enabling two-factor authentication wherever possible.
