Speaking at security events

I don't claim to be an amazing speaker; I'm still in awe of great infosec speakers such as Mikko Hypponen, Charlie Miller, Mudge and many others. However, I do keep being invited back to speak at events, so I guess I'm doing something right. Sometimes it's a minor slot at a big event, but 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...

FakeNet Genie: Improving Dynamic Malware Analysis with Cheat Codes for FakeNet-NG

As developers of the network simulation tool FakeNet-NG, reverse engineers on the FireEye FLARE team, and malware analysis instructors, we get to see how different analysts use FakeNet-NG and the challenges they face. We have learned that FakeNet-NG provides many useful features and solutions of...

Turning an OBD-II reader into a USB / NFC attack tool

One of my favourite sorts of hardware hacking is making a device do something it was never intended for. It's creative, disruptive, and fun. Everyone has their own way of going about things. Different methodologies, habits, and skill sets mean that approaches will be diverse. This is how I work...
