    KadNap proxy botnet disclosure

    Initial Disclosure

    Lumen/Black Lotus Labs disclosed KadNap as a new malware family targeting Asus routers and other edge devices to build a stealth proxy botnet, with more than 14,000 infected devices and over 60% of victims in the U.S. The malware uses a custom Kademlia DHT to conceal command-and-control infrastructure, relies on aic.sh and cron-based persistence to rename and run .asusrouter and kad, can target ARM and MIPS devices, and is linked to Doppelgänger, a proxy service assessed as a rebrand of Faceless.
