Why should users be careful when granting permissions to Android apps?

Downloading and installing applications on Android devices, whether from the reputable Google Play store or from other sources such as the files used to distribute and install applications on the Android operating system (also known as APK files: Android Package Kit), can potentially be infected with malware. This is a threat that most Android users face.

Compared to iPhone users, Android users are generally at greater risk from malware. This is not because the Android operating system is less secure, but mainly because the larger Android ecosystem with its myriad of devices and diverse ways to install apps makes it easier for cybercriminals.

Of the many permissions that Android apps can request, the three most important permissions that Android apps often request are accessibility permissions, notification permissions, and SMS message reading permissions. Understanding and managing these permissions is key to protecting users' devices from malware.

What makes Android more vulnerable to malware than other operating systems?

Android and iOS operating systems have many similarities in terms of user experience, both operating systems provide similar experiences and support most popular applications.

However, one key difference lies in the approach to app installation. While iOS restricts app installation to the App Store, Android allows users to install apps from a variety of sources, including direct downloads via APK files. This openness is a double-edged sword, giving users more freedom and flexibility, but also exposing them to more risk.

The diversity of the Android ecosystem, both in terms of devices and the availability of apps, makes it an attractive target for attackers. With more devices in circulation, the chances of a device being attacked by a cybercriminal increase. Additionally, allowing apps to be installed from outside the official Google Play Store also creates more opportunities for malware to find its way onto a user's device.

The Importance of App Permissions in Preventing Malware

Every time a user installs an app on an Android device, whether from the Google Play Store or via an APK file, the user is required to grant it certain permissions. These permissions allow the app to access various features and data on the device. While some permissions are necessary for the app to function properly, others can be exploited by malware.

Malware often disguises itself as a legitimate application, requesting permissions that allow it to perform malicious activities in the background without the user’s consent. This can include stealing personal information, inserting advertisements, or even authorizing transactions without the user’s consent. Therefore, understanding and managing app permissions is essential to protecting users’ devices from malware.

3 important rights that users need to pay attention to to avoid becoming a victim of malware

1. Access Rights

Accessibility Permission is a special feature on mobile operating systems, including Android and iOS. When an application is granted access, it can interact with other user interface elements on the device, such as reading the content on the screen, describing the actions that are taking place, or even performing actions on behalf of the user.

Accessibility permissions are designed to make it easier for disabled users to interact with their Android devices. However, they have also become a popular target for malware. Granting access to a malicious app can give it extensive control over a user's device, including the ability to read and interact with other apps.

While not all apps that request access are malware, users should exercise caution. If an app requests this permission, consider whether it is truly necessary for it to function. If the user is unsure or if the app does not inspire trust, it is best to deny the request.

2. Notification Access

Notification Access Permission is a special permission that users can grant to applications on their Android devices. This permission allows the application to read all the user's notification content, including messaging applications, email, social networks, etc.

Malware can exploit this to capture information such as one-time codes sent for two-factor authentication (2FA). By accessing these codes, malware can authorize actions such as banking transactions or service subscriptions without the user's consent.

To protect yourself, carefully monitor which apps have notification access. Only grant this permission to apps that you trust and need it to function properly.

3. Right to read SMS messages

SMS Reading Permission is a special permission that users can grant to applications on their Android devices. When an application is granted this permission, it can read, send, and delete SMS messages on the phone.

SMS messages are often used to send security codes and other sensitive information. A malicious app with permission to read SMS messages could intercept these messages and use the information to perform unauthorized transactions or other malicious activities.

Although newer versions of Android have deprecated this permission in favor of more secure Application Programming Interfaces (APIs), it is still important to check which apps have access to SMS. If a user encounters an app that has this permission without a clear need, consider revoking it immediately.

Simple Steps to Protect Your Android Device from Malware

1. Choose your apps wisely

Choosing and using the right application is one of the important factors to protect Android devices from malware threats. Accordingly, users should use safe sources, that is, download applications from the Google Play Store or other trusted places. Avoid downloading applications from unknown websites.

Besides, users need to check reviews and ratings before installing, this helps users better understand the features, effectiveness and problems that the application may encounter.

At the same time, users need to consider the access permissions that the application requests, avoid granting too many access permissions to an application, especially sensitive permissions such as access to contacts, messages, location or camera.

2. Control application access

Granting permissions to apps on Android phones is essential for them to function properly. However, if not careful, granting too many permissions can leave the user's device vulnerable to malware. Therefore, controlling app access is extremely important to protect the device.

Accordingly, users should not grant permissions to apps if they are not sure why they need them. Only allow important apps to send notifications. Be careful with apps that ask for access to SMS messages, only grant SMS sending permission to apps that users trust, such as banking apps or messaging apps.

3. Always update your phone to new versions

Regular updates are one of the most effective ways to protect your Android phone. New updates not only bring new features, but also patch security holes, making your device safer from malware threats.

In addition, users need to use effective security applications, that is, download good security applications to scan for malware to protect the phone safely.

4. Stay safe online

To keep your Android device safe online, avoid clicking on links or opening attachments from people you don't know. You should also add an extra layer of security to your online accounts by using two-factor authentication (2FA) and creating a backup of your data on your phone in case something goes wrong.

In short, protecting your Android phone starts with understanding and controlling the permissions your apps have. Every permission you grant an app is an open door for cybercriminals to access your personal data. Be careful about what you share. By regularly reviewing and adjusting permissions, you are building a solid firewall against malware attacks. Remember, you are proactive in protecting your device.
