Built by Google Android A bug has recently been identified in the operating system that could cause hacking for 99 percent of the world’s devices powered by software. Technology experts say the error is a major risk. Security research firm Bluebox Security Reported They have found the “Android Master Key” which helps to turn virtually any Android application into malware.

Using this error can take away access to any function including call, message and any other device. Hackers. In this case the phone owner, Google Or app developer – no one needs permission!

The bug in question made its home on the platform from Android 1.6 Donut four years ago. Jeff Foristal, CTO of Bluebox Security, said they have found a way to modify the code of an Android app without breaking its cryptographic signature.

Note that Android The software verifies this cryptographic signature before the system can access any application. If the signature of the modified app does not match with the signature given by the developer, it will not be approved. As a result, the app cannot do any harm to the device or information coming from unknown or any third source. Usually the signature of the modified app differs from the signature given by the developer. But the above error called “Android Master Key” can work without breaking the cryptographic sign.

Google While Play Store server applications may be safe from such app-tampering, hackers can harm software / updates downloaded from various third-party stores. In this case, it is not very difficult to trap ordinary users by showing fake software update notifications through phishing emails.

Bluebox also reports that they reported the bug to Google in February. Already providing patches for bug fixes for the Samsung Galaxy S4 Although The Google Nexus series has not yet received a fix (but is in the process of being processed); On the other hand, the old Android build remains.

Android For devices you can be safe from this newly released bug just by downloading / updating the software from the official app store Google Play. And, install the OS update as soon as possible.
