Introduction️ To perform a security audit of an Android application, it is necessary to create a customized environment, which can be based on a physical device or an emulator. For most cases, an emulator will suffice. In this article we will create a virtual machine for Android in x86_64 architecture, and modify it by installing Magisk, to obtain superuser permissions and install modules, and install some applications.️ Installing the Android Emulator For the Android emulator, we have chosen the official Android IDE, Android Studio, which includes support for Android Virtual Devices (AVD). To install the IDE, simply go to its official website and download the installer by accepting the license terms. During the installation process, when selecting the components to install, we will deselect the option Android Virtual Device, as we will configure it later. In this case, we will install the IDE in our Documents directory.️ ...

Introducción The buffer overflow, also known as buffer overflow, is a security vulnerability in software programming that occurs when more data is introduced into a memory area (buffer) than it can handle. This situation may allow an attacker to overwrite adjacent data in the memory, which potentially leads to the execution of malicious code or alteration of a program’s flow.️ When a program does not verify the amount of data entered into a buffer, it risks an attacker exploiting this weakness to inject malicious code, overwrite important information or even take control of the system. Prevention of buffer overflow involves good programming practices and the use of security techniques such as input validation and boundary checking to prevent this type of vulnerability.️ ...
