Google Stops Malicious Apps With 'AI-Powered Threat Detection' and Continuous Scanning

Android and Google Play have billions of users, Google wrote in its security blog this week. 'However, like any flourishing ecosystem, it also attracts its share of bad actors... That's why every year, we continue to invest in more ways to protect our community.' Google's tactics include industry-wide alliances, stronger privacy policies, and 'AI-powered threat detection.'

'As a result, we prevented 2.36 million policy-violating apps from being published on Google Play and banned more than 158,000 bad developer accounts that attempted to publish harmful apps. '

To keep out bad actors, we have always used a combination of human security experts and the latest threat-detection technology. In 2024, we used Google's advanced AI to improve our systems' ability to proactively identify malware, enabling us to detect and block bad apps more effectively. It also helps us streamline review processes for developers with a proven track record of policy compliance. Today, over 92% of our human reviews for harmful apps are AI-assisted, allowing us to take quicker and more accurate action to help prevent harmful apps from becoming available on Google Play. That's enabled us to stop more bad apps than ever from reaching users through the Play Store, protecting users from harmful or malicious apps before they can cause any damage.

Starting in 2024 Google also 'required apps to be more transparent about how they handle user information by launching new developer requirements and a new 'Data deletion' option for apps that support user accounts and data collection.... We're also constantly working to improve the safety of apps on Play at scale, such as with the Google Play SDK Index. This tool offers insights and data to help developers make more informed decisions about the safety of an SDK.'

And once an app is installed, 'Google Play Protect, Android's built-in security protection, helps to shield their Android device by continuously scanning for malicious app behavior.'
Google Play Protect automatically scans every app on Android devices with Google Play Services, no matter the download source. This built-in protection, enabled by default, provides crucial security against malware and unwanted software. Google Play Protect scans more than 200 billion apps daily and performs real-time scanning at the code-level on novel apps to combat emerging and hidden threats, like polymorphic malware. In 2024, Google Play Protect's real-time scanning identified more than 13 million new malicious apps from outside Google Play [based on Google Play Protect 2024 internal data]...

According to our research, more than 95 percent of app installations from major malware families that exploit sensitive permissions highly correlated to financial fraud came from Internet-sideloading sources like web browsers, messaging apps, or file managers. To help users stay protected when browsing the web, Chrome will now display a reminder notification to re-enable Google Play Protect if it has been turned off... Scammers may manipulate users into disabling Play Protect during calls to download malicious Internet-sideloaded apps. To prevent this, the Play Protect app scanning toggle is now temporarily disabled during phone or video calls...

Google Play Protect's enhanced fraud protection pilot analyzes and automatically blocks the installation of apps that may use sensitive permissions frequently abused for financial fraud when the user attempts to install the app from an Internet-sideloading source (web browsers, messaging apps, or file managers). Building on the success of our initial pilot in partnership with the Cyber Security Agency of Singapore (CSA), additional enhanced fraud protection pilots are now active in nine regions — Brazil, Hong Kong, India, Kenya, Nigeria, Philippines, South Africa, Thailand, and Vietnam.

In 2024, Google Play Protect's enhanced fraud protection pilots have shielded 10 million devices from over 36 million risky installation attempts, encompassing over 200,000 unique apps.
