Kimwolf v7 Botnet Enhances Stealth with Chrome-Like Traffic, Targets Android TV Devices The Kimwolf v7 botnet has evolved to evade detection by mimicking legitimate web traffic, posing a heightened threat to Android TV boxes and set-top devices. First identified in February 2026 by Unit 42, this latest iteration leverages HTTP/2 floods with Chrome-like browser fingerprints, making malicious requests harder to distinguish from genuine user activity. Originally active since 2024, Kimwolf shifted focus to Android devices in 2025, exploiting exposed Android Debug Bridge (ADB) services via residential proxies to install malware without authentication. Compromised devices often used unknowingly by owners can be weaponized for distributed denial-of-service (DDoS) attacks, as demonstrated by the record-breaking Aisuru DDoS incident. Key upgrades in Kimwolf v7 include: - HTTP/2-based attacks that replicate browser headers, complicating defensive filtering. - Performance-optimized UDP floods tailored for ARM processors in TV hardware. - Removal of scanning/exploitation tools, suggesting a split between infection and attack operations. - Resilient command infrastructure using Ethereum Name Service (ENS) records, Tor hidden services, and fallback relays to resist takedowns. Defenders are advised to monitor for unusual blockchain connections from IoT/Android devices, proxy activity, and local proxy behavior. Disabling ADB or restricting it to USB-only access can mitigate infection risks. Indicators of Compromise (IoCs) include payload hashes, domains like rpcuniverse[.]com, and IP addresses such as 23.94.221[.]104, linked to the botnet’s infrastructure. The malware’s adaptability underscores the persistent threat posed by compromised consumer devices in large-scale attacks.
