14,000 routers are infected by malware that's highly resistant to takedowns

A botnet of 14,000 routers, primarily Asus models, has been infected with the KadNap malware, creating a takedown-resistant proxy network for cybercrime. The malware exploits unpatched vulnerabilities in the routers, with a high concentration of Asus devices likely due to reliable exploits available for those models. The botnet's sophisticated peer-to-peer design based on Kademlia makes it challenging to detect and take down through traditional methods, using distributed hash tables to conceal command-and-control servers' IP addresses. This decentralized structure and hash substitution provide resilience against takedowns and denial of service attacks.
