As smartphones and computers evolve, so do the security measures required to protect devices. While manufacturers are constantly trying to protect devices with new updates, hackers are also constantly looking for new vulnerabilities.

If you remember, in Windows 10 and 11 in recent weeks a critical vulnerability was found. Today it’s almost time can endanger all Android devices It turns out that a major security flaw has been discovered.

All applications with viruses can be signed securely

With an update to the Google Play Store last year, it regularly scans the applications you install on your phone and notifies users when it detects an application that could harm your phone. A similar system has been created by Samsung’s security application and Xiaomi’s security application. These systems are usually application packages (APK) checking their signatures and comparing them to malicious application signatures captured in many cybersecurity systems, especially Google.

However, according to the information revealed by Google’s malware engineer Lukasz Siewierski, hackers can use this malware for another application or a computer through different platforms. able to sign as system application and bypass firewall. Even worse, these applications can be real system applications with viruses embedded in them.

To test the updates of the applications, users generally prefer to download the beta version of the application from the platforms on the internet. Some users APKMirror Although they prefer legal websites supported by Google, some users download the application from the first website they see. If you too jump headlong into the first site you see or if you constantly download modded apps With this method, you may have infected your phone with a virus.

Manufacturers such as Samsung and Xiaomi are at greater risk

For this method to work, hackers need the platform key of the applications. Although Google’s leaked or hacked program keys usually belong to the old versions of the applications, according to the statement from APKMirror, companies that recently produced competing applications from Google, such as Samsung and Xiaomi. current keys of many applications were stolen.

In the study, viruses in applications with old keys can be detected by the firewalls of the devices, while malware can be detected with updated keys. unfortunately not detected.

If you think you are affected by this method, which was found to have been used in November, the only thing you can do is as soon as possible. format your phone will be.
