How to train your Ghidra

Getting started with Ghidra For about two decades, being a reverse engineer meant that you had to master the ultimate disassembly tool, IDA Pro. Over the years, many other tools were created to complement or directly replace it, but only a few succeeded. Then came the era of decompilation, adding...

Reverse Engineering Keys from Firmware. A how-to

TL;DR It is possible to reverse engineer keys from firmware with some tips: 1. Always looks for strings/constants. 2. Make guesses about the original source. 3. Find a function you can recognise and work backwards to identify other functions. 4. It helps if they use open-source code so you can cr...

Reverse Engineering Tools: Evaluating the True Cost

When sourcing software for business needs, what criteria should you follow? Price typically tops the list. And sure, free software, like the Linux OS, delivers cost savings, stability, flexibility and ongoing development. No argument there. But when it comes to decompilers, which are used for...

NSA Warns Smartphones Leak Location Data

Mobile devices expose location data in more ways than most people know, and turning off services such as Find My Phone, Wi-Fi and Bluetooth can help mitigate tracking, but are no silver bullet that prevents a third party from tracking users. That’s advice shared by U.S. top spy division, the...

Part two: Reverse engineering and patching with Ghidra

In the first installment of our three-part blog series we learned how to root the Flashforge Finder 3D printer and acquire its firmware. In this post, we will delve into reverse engineering and patching the software using the new open source NSA tool Ghidra, which rivals its expensive competitors...

What does it take to become a good reverse engineer?

How much money and effort does it take to become a good reverse engineer? Do you even need to be one? There are no universally acceptable answers to these questions. Software reverse engineering RE is not a science but a skillset combined with specific knowledge and backed by a lot of experience...
