1.3 Million Android TV Boxes Shipped with Pre-Installed Botnet Backdoor
A Google Threat Intelligence Group report revealed that Chinese OEM Videostrong Technology Co. intentionally embedded a backdoor, x.cpe, into Android TV boxes and other IoT devices, enrolling over 1.3 million devices into the XCPE botnet for financial gain. The malware operated at system level, survived firmware resets, and was monetized by selling access to criminal affiliates who conducted ad fraud, operated residential proxy networks, and distributed additional malware. Google, with industry partners and Japan's National Police Agency, disrupted command-and-control infrastructure and took legal action against Videostrong, banning it from supplying software for certified Android devices. The takedown also cut access to over 10 million other compromised devices. While the infrastructure is disrupted, infected devices remain persistent, posing a long-term risk to consumers.
This is a significant security incident that impacts the ad tech ecosystem: the botnet was used for ad fraud, a major threat to advertising integrity. The takedown by Google affects Android TV supply chains and highlights vulnerabilities in advertising infrastructure.

Kimwolf v7: Android/IoT Botnet Using ENS, Tor, HTTP/2
Unit 42 (Palo Alto Networks) published a technical analysis of Kimwolf v7, an evolved Android/IoT botnet that infects unauthenticated ADB-enabled Android TV boxes via residential proxy exit nodes. Once installed (APK or ELF), the bot runs under disguised process names (e.g., netd_service, TVHelper), hosts a local SOCKS proxy on 127.0.0.1:23075, and uses a fault-tolerant three-layer C2 resolution combining ENS-based lookups through legitimate Ethereum RPC endpoints, Tor v3 hidden services, and the local proxy. Kimwolf v7 supports 15 DDoS methods, including high-performance HTTP/2 floods that build Chrome/Safari-like browser fingerprints (using nghttp2) and L3/L4 floods accelerated with Xorshift256 and ARM NEON SIMD. Unit 42 provides IOCs and mitigation guidance for SOCs and administrators to detect and contain infections.
Undetectable Firmware Malware 'Midnight Mimosa' Hits Cheap Androids
Security researchers at Bitdefender have uncovered a malware campaign named 'Midnight Mimosa' that pre-installs malicious firmware on budget Android smartphones. The malware is embedded in the device's system firmware, giving it system-level access and making it nearly impossible to remove. It operates stealthily by temporarily disabling the Google Play Store app to avoid detection by Google Play Protect while executing malicious functions. The malware is used for ad and click fraud, generating fake impressions without user consent. Bitdefender discovered 32 disguised apps associated with the campaign, affecting devices in over 150 countries, with Mexico (13%) and France (12.5%) most impacted. Some affected devices are counterfeit clones of premium models like the Galaxy S24 Ultra, but genuine Samsung phones are not affected. Additionally, 13 apps from the Google Play Store were found communicating with the same malicious infrastructure, indicating broader reach.
Smart TV owners hack operating systems with AI against ads
Smart TV owners are increasingly using AI coding assistants to remove pre-installed advertising and tracking software from their devices. The trend, known as 'Vibe Coding', has been highlighted by a developer who used Anthropic Claude Code to clean up a Xiaomi TV, leading to the open-source project Cleanyourtv. This project uses the Android Debug Bridge (ADB) to disable unwanted apps on Android TV and Google TV platforms. For manufacturers like Samsung, LG, and Hisense, smart TVs are ad platforms and data sources, making this consumer pushback challenging. The article also references the Texas Attorney General's lawsuit against major TV makers in December 2025 for unauthorized data collection via ACR technology, and the 2017 Vizio case. While the security risks of such modifications are noted, the growing ease of AI-assisted customization signals a shift in consumer control.
