Flipper Zero, a hacker multitool created by Russian developers, has become quite famous by now. At the beginning of 2021, the project raised almost 5 million USD on Kickstarter, and the community keenly followed production-related twists and turns and subsequent difficulties with its distribution and delivery. In this article, I am going to share my Flipper-related for you to decide whether such a device is worth purchasing or not.

In the hands of a hacker, an ordinary Android smartphone can become a formidable weapon – either on its own or in combination with other devices. But hardware is only one component of hacker’s success: to transform a phone into a hacker tool, special software is required.

Once, while being on a job search, I received an interesting test assignment: analyze Viber for Android, find vulnerabilities in it, and exploit them. Using this episode as an example, I will demonstrate you an efficient approach that can be used to analyze real apps and obtain results in a short time. Joking aside: if you go through all the steps described below, you have a good chance to find a 0-day vulnerability in Viber. 😉

Each of us uses satellite navigation to get anywhere outside our backyard. But what if GPS, as of a sudden, stops working and cannot be used to determine your location anymore? This article presents an efficient technique enabling you to fool GPS.

From a hacker’s perspective, a mobile phone is the most handy tool for computer attacks, especially for attacks that require semiphysical access and are delivered over a radio channel. In this article, I will explain how to transform an ordinary Android smartphone into a powerful hacker weapon.

Java or Kotlin are not the only languages you can use to create apps for Android. C# programmers can develop mobile apps using the Xamarin open-source platform. Today, I will explain how to research such apps and find ways to hack them.

One day I encountered a technical issue: I had to put a phone connected to a single-board Raspberry Pi computer into the USB-tethering mode on boot. To do this, I used Android Debug Bridge (ADB), a handy debugging interface for Android devices. There are several ways to automate the work of apps on an Android smartphone using ADB, and this paper examines one of them.
