A newly discovered botnet malware called KadNap is targeting ASUS routers and other edge networking devices to turn them into proxies for malicious traffic. Since August 2025, KadNap has grown to 14,000 devices that are part of a peer-to-peer network and connect to the command-and-control (C2) infrastructure through a custom version of the Kademlia Distributed Hash Table (DHT) protocol. This makes identifying and disrupting the C2 servers more difficult because the information is decentralized, and each node manages a subset of the complete data. According to researchers at Black Lotus Labs, the threat research and operations arm of Lumen Technologies, nearly half of the KadNap network is connected to C2 infrastructure dedicated to ASUS-based bots, and the rest communicate with two…
