Internet of Planes: Hacking Millionaires’ Jet Cabins
The push to incorporate remote management capabilities into products has swept across a number of industries. A good example of this is the famous Internet of Things (IoT), where modern home devices from crockpots to thermostats can be managed remotely from a tablet or smartphone. One of the biggest problems associated with this new feature is a lack of security. Unfortunately, nobody is surprised when a new, widespread vulnerability appears in the IoT world. However, the situation becomes a bit more concerning when similar technologies appear in the aviation sector….
Extracting Bluetooth Metadata in an Object’s Memory Using Frida
Here’s a script I wrote to extract information from the Bluetooth metadata in an object’s memory. The script makes use of the Frida instrumentation framework, and I’ll take a little time to explain a simple scripting methodology/thought framework for solving problems with Frida. What you will need: Frida Server for your device https://www.frida.re/docs/installation/ Frida script to run https://github.com/IOActive/BlueCrawl Target Android phone (preferably with root permissions) Getting Started: Your first Script Frida forwards APIs that wrap Java objects and introduce means to inspect them, modify…
Discovering and Exploiting a Vulnerability in Android’s Personal Dictionary (CVE-2018-9375)
I was auditing an Android smartphone, and all installed applications were in scope. My preferred approach, when time permits, is to manually inspect as much code as I can. This is how I found a subtle vulnerability that allowed me to interact with a content provider that was supposed to be protected in recent versions of Android: the user’s personal dictionary, which stores the spelling for non-standard words that the user wants to keep. While in theory access to the user’s personal dictionary should be only granted to privileged accounts,…
Is Stegomalware in Google Play a Real Threat?
For several decades, the science of steganography has been used to hide malicious code (useful in intrusions) or to create covert channels (useful in information leakage). Nowadays, steganography can be applied to almost any logical/physical medium (format files, images, audio, video, text, protocols, programming languages, file systems, BIOS, etc.). If the steganographic algorithms are well designed, the hidden information is really difficult to detect. Detecting hidden information, malicious or not, is so complex that the study of steganalytic algorithms (detection) has been growing. You can see the growth in scientific…
