Sideloading – how to install applications safely

Every day we use mobile apps, which we most often download from official sources such as Google Play or the App Store. However, what if the app you need is not available there? In such situations, some users turn to sideloading – the process of installing software from external sources, outside the official stores. This solution gives you more freedom, but it also comes with some risks. In this article, we’ll explain what sideloading is, what benefits it can bring and what risks to be aware of.

How does sideloading work?

Sideloading is the installation of an application on a device, bypassing official sources such as Google Play or the App Store. It is most often done by downloading an installation file (such as an APK file in the case of Android) directly from a website or other source. On Android devices, the process is relatively simple: just download the file and allow installation from unknown sources in the settings. On iOS, sideloading is more complicated, as Apple restricts the ability to install apps from outside the App Store, requiring jailbreaking or a special developer account.

Why do users use sideloading?

Sideloading gives users the freedom to access apps that are not available in official stores. Here are the most common reasons why users opt for this method:

  1. Access to regionally restricted applications – some applications are only available in certain countries, and sideloading allows them to be installed regardless of location.
  2. Beta versions – developers can release test versions of applications before they hit official stores, allowing early testing of new software.
  3. Older versions of apps – sideloading allows you to install older versions of apps that may work better on older devices.
  4. Additional features – some apps offer more features in versions available outside the official stores, due to Google or Apple regulatory restrictions.

The dangers of sideloading

While sideloading gives more freedom, it carries serious risks. Apps installed from outside official stores may be unsecured, and users lose confidence that the app has been checked for security. Here are the top risks:

  1. Malware – Applications from outside trusted sources may contain viruses, Trojans and other malware that can take over your data.
  2. Interception of personal data – Unauthorized apps can access personal data, photos, text messages and even bank accounts.
  3. No updates – Apps installed outside official stores will not be automatically updated, which can lead to security problems.
  4. Ransomware – There is a risk that an application from an unknown source will take control of your phone, demanding a ransom to unlock your device.

One of the most dangerous cases was the use of banking trojans, such as Flubot and TeaBot, which were spread by apps installed from unauthorized sources. These malicious programs stole banking login credentials, intercepted SMS messages and stole authorization codes, allowing hackers to take over users’ bank accounts. Users often didn’t realize their devices were infected until they lost money from their bank accounts

Another risk is ransomware and spyware, which can take control of a device, block access to data and demand a ransom in exchange for unlocking it. An example is the infection of Android devices with Trojans impersonating popular apps that were available in unofficial app stores. In such cases, attackers can completely take control of the device, which poses a serious threat

Is sideloading safe?

Unfortunately, installing applications from outside authorized sources always comes with risks. Even if an application appears to work normally, it may contain malicious code. The sideloading phenomenon is popular, among other reasons, because users often want to avoid paying for paid software by installing pirated versions. This, however, increases the risk of attacks and security problems.

However, not all applications from external sources are dangerous. In many cases, sideloading includes:

Beta versions of applications that are still in the testing phase.

Apps not available in the official store, but compatible with the device.

Software available in other regions that you want to install on your device.

In such cases, sideloading can be useful, but it is always a good idea to make sure that the installation file comes from a verified, trusted source.

How to avoid the dangers of sideloading?

To minimize the risks associated with installing applications from outside official sources, it’s a good idea to follow a few rules:

Do not unlock the option to install from unknown sources unnecessarily. This feature should only be enabled if you are sure the source is secure.

Avoid clicking on suspicious links, especially those sent via SMS or instant messaging.

Install antivirus software on your device to detect potential threats.

Use only verified sources – before installing an app, look for reviews of it on the Internet and make sure it comes from a trusted source.

Is it worth installing apps from outside official sources?

Sideloading is a process of installing apps from outside the official stores that offers greater flexibility, but carries serious risks. While it can give access to apps not available on Google Play or the App Store, users should be aware of security risks. It’s a good idea to avoid downloading apps from insecure sources, and if you do decide to sideload, make sure the file comes from a trusted place and take proper precautions, such as antivirus software.

It’s always worth remembering that the security of our data and devices should be a priority, and not every app outside the official store is secure.
