Google Tightens Android Security: Sideloading Apps with Risky Permissions Face Blockade


Google Play Protect, the built-in security suite for Android devices, is receiving a new weapon in its fight against malicious apps. The company is currently testing a pilot program that blocks the sideloading of Android apps requesting specific risky permissions. This move aims to tackle a growing concern: financial fraud perpetrated through apps downloaded outside the official Google Play Store.

Key Highlights:

  • Google launches a pilot program blocking sideloading of Android apps requesting risky permissions.
  • Targets apps seeking access to SMS, notification, and screen mirroring, often used for financial fraud.
  • Initiative follows real-time scanning rollout in select regions to combat malware in downloaded APKs.
  • Raises concerns about potential impact on legitimate use cases and developer freedom.


Sideloading, the process of installing apps from sources other than the Play Store, can be a risky endeavor. While it allows users to access apps unavailable through official channels, it also bypasses Google’s rigorous security vetting process. This exposes users to the potential dangers of malware, spyware, and other malicious software disguised as legitimate apps.

The new pilot program specifically targets apps requesting access to permissions often exploited for financial fraud. These include:

  • SMS and notification access: Malicious apps can intercept one-time passwords (OTPs) sent through SMS or notifications to gain unauthorized access to financial accounts.
  • Screen mirroring: Fraudsters can use this permission to capture sensitive information displayed on the user’s screen, such as login credentials or banking details.

While the specific details of the pilot program are yet to be made public, it likely leverages machine learning models trained to identify apps with suspicious permission requests. If an app triggers these flags during the sideloading process, it will be blocked from installation.

This initiative follows Google’s October 2023 rollout of real-time scanning for downloaded APKs in regions like India, Thailand, Brazil, and Singapore. This feature scans APKs for malicious behavior before installation, providing an additional layer of security for users who choose to sideload apps.

However, the move to block sideloading based on permissions raises concerns about potential overreach and impact on legitimate use cases. Developers who rely on sideloading for app distribution, especially those targeting niche audiences or beta testing, might face hurdles. Additionally, users who require specific apps unavailable on the Play Store, for work or accessibility purposes, could be inconvenienced.

Google has yet to clarify how it plans to address these concerns while ensuring user safety. Balancing security with user freedom and developer flexibility will be key to the success of this pilot program.

Impact on Users:

  • Increased security against financial fraud and malware disguised as sideloaded apps.
  • Potential limitations in accessing niche or unavailable apps not on the Play Store.
  • Importance of staying informed about program developments and potential alternatives.

Ultimately, Google’s efforts to enhance Android security are commendable. However, striking the right balance between protection and user choice remains a delicate task. As the pilot program progresses, it will be crucial to monitor its effectiveness and address potential unintended consequences to ensure a secure and open Android ecosystem.
