CloudFlare & OpenDNS Work Together to Help the Web

This post introduces the "Visitor DNSChanger Detector App," a proactive security measure developed by Cloudflare. This app, deployable via the Cloudflare Apps marketplace or as open-source JavaScript, identifies users whose systems are infected with DNSChanger malware and are using compromised DNS servers. It informs these users about their infection and directs them to resources for remediation, thereby preventing potential internet access loss and protecting them from malicious redirection. This initiative highlights Cloudflare's role in broader internet health and user safety, extending beyond direct website security to address systemic threats.
