Google's AI Cuts Play Store Malware by Millions in 2025
Google's 2025 Android app ecosystem safety report says its increased investments in proactive security and AI helped deter malicious apps from reaching the Play Store. The company reported preventing 1.75 million policy-violating apps from being published in 2025 (down from 2.36 million in 2024), banning more than 80,000 developer accounts, and running over 10,000 safety checks on every published app. Google said it integrated generative AI models into the app review process, blocked 160 million spam ratings/reviews, and prevented 255,000 apps from gaining excessive access to sensitive data. Google Play Protect identified more than 27 million new malicious apps outside the Play Store, suggesting attackers are increasingly bypassing the store. Google plans to increase AI investments in 2026 to address emerging threats.
Major platform (Google) published a security report and described AI-driven, ecosystem-level protections that reduce malicious apps, which affects app-store integrity, in-app inventory quality, fraud risk and advertiser/publisher trust across mobile ecosystems.

Google Eradicates 115 Fraudulent Apps Impacting 25 Million Devices
Google and Integral Ad Science (IAS) disrupted a large Android-based ad-fraud operation called Genisys that used over 115 mobile apps and AI-generated shell websites to generate fraudulent ad traffic across more than 25 million devices. The scheme covertly used in-app browsers to send traffic to nearly 500 AI-generated domains, misrepresented app bundle IDs (including popular app IDs like Netflix and Instagram) to obscure the activity, and produced millions of bid requests that served ads to non-human or low-quality inventory. IAS detected the operation in September 2025 and tracked its peak in December; Google removed the apps from the Play Store and updated protections (Google Play Protect) to disable Genisys-affiliated apps. IAS reports Genisys-related bid requests have fallen by over 95%.
Google Enhances Sideloading for Android with Scam Protections
Google announced an “advanced flow” setting for Android that lets device owners disable the Play Store verification requirement to sideload apps while introducing multiple anti‑scam safeguards. The one‑time process requires enabling developer mode, a quick check to detect coaching, a phone restart and reauthentication, and a one‑day waiting period before users confirm the change via biometrics or PIN. After completion users can allow installs from unverified developers for seven days or indefinitely, with persistent warnings shown. Google also offers free limited distribution accounts for students and hobbyists (up to 20 users). The move follows Google’s settlement with Epic Games and Play Store commission changes.
Google Blocks Billions of Ads in 2025
Google's Ads Safety Report 2025 shows the company blocked or removed more than 8.3 billion ads and suspended 24.9 million advertiser accounts. Google says it now detects over 99% of policy-violating ads before they are served by shifting checks earlier in the submission process and using Gemini models that analyze campaign context and hundreds of billions of signals. The report also states false-positive account suspensions fell by 80% year-over-year and that Google processed roughly four times as many user reports as the prior year. The company frames the changes as increased precision and earlier intervention to combat scalable fraud enabled by generative AI, while acknowledging greater advertiser dependence on proprietary model-based decisions.
