Now days, smartphones and tablets are most the popular gadgets. If we see recent stats, global PC sale has also been decreasing for the past few months. The reason behind this is that people utilize tablets for most of their work. And there is no need to explain that […]
In the previous article, we looked at how we can use Sogeti Data protection tools to boot an iDevice using a custom ramdisk with the help of a bootrom exploit. In this article, we will look at a tool named iNalyzer than we can use for black box assessment […]
In Part 1 of the article we have discussed about the iPhone application traffic analysis. Part 2, Part 3, and Part 4 covered in-depth analysis of insecure data storage locations on the iPhone. Part 5 covered runtime analysis basics with Cycript. In this part we will take a look […]
The recently discovered master key vulnerability in Android has given a jolt to the Android team and other parties involved. This vulnerability allows attackers to inject malicious code into legitimate Android applications without invalidating the digital signature. It’s very easy for hackers and attackers to take advantage of this […]
In the previous article, we looked at how we can boot a device using a custom ramdisk using Sogeti Data protection tools. In this article, we will look at how we can use some of their tools to gather information from the device like fetching the keychain information, dumping […]
In the previous article, we looked at how we can use Keychain-Dumper and Snoop-it to analyze and dump the contents of the Keychain from an IOS device. In this article, we will look at how we can boot a non-jailbroken device using a custom ramdisk and analyze the contents […]
In this paper I’ll show you how to find an Android’s user pattern lock. I assume that the technique that I’ll demonstrate can work only on a rooted device. Actually, this article will be based on a problem given on a web-based CTF (Capture the Flag, a computer security […]
My OUYA has finally arrived and I have had some fun tinkering with it, but we will not be talking about OUYA today. In this article, we will continue enumerating other cool embedded devices that can be used for home automation, physical security locks, retro gaming consoles, penetration testing, […]
In the previous article, we looked at the different ways in which we could analyze the network traffic and the api calls being made through an IOS application. In this article, we will look at how we can dump the contents of the Keychain from an IOS device.
In the previous article, we looked at IOS filesystem and forensics. In this article, we will be looking at how we can analyze the network traffic flowing across an IOS device. Analyzing the network traffic for an application could be helpful in many ways. It could help us deduce […]
While security of mobile operating systems is one of the most researched topics today, exploiting and rootkitting ARM-based devices gets more and more interesting. This article will focus on the exploitation of TEEs (Trusted Execution Environments) running in ARM TrustZone to hide a TrustZone-based-rootkit.
First let’s take a look over […]
In this article, we will be looking at the IOS filesystem, understand how the directories are organized, look at some important files, and look at how we can extract data from database and plist files. We will look at how applications store their data in their specific directories (sandbox) […]
Wikipedia defines Mobile Device Management (MDM) solutions as solutions that secure, monitors and supports mobile devices, deployed across various Mobile service providers and operators. This domain of technology sweeps its charms over Smartphones, Tablets, Tablet Computers, mobile printers and various other devices dependent on On-The-Air (OTA) technology. The primary […]
In some of the previous articles, we have looked at how we can dump class information of IOS apps using class-dump-z, hook into the runtime using Cycript and perform runtime manipulation and method swizzling, analyze the flow of the app using gdb etc. However, there could be a much […]
In the previous article, we looked at how we can install custom apps on our device without a developer certificate. In this article, we will look at how we can perform method Swizzling using Cycript on a sample application.
The first thing is to download the sample Xcode project. You […]
IOS Application Security Part 7 – Installing and Running Custom Applications on Device without a registered developer account
Usually, to test apps on a device, you need to be a registered developer which costs about $99/year. For people who want to learn IOS Application security, it is very important that they should be able to run applications on device so that they can perfom tests on them. […]
As we all know, Apple recently introducted its new version of IOS at WWDC 2013 with a completely redesinged User Interface. If you haven’t seen it yet, check out this video from WWDC 2013.
