Router Ruh Roh is a hands-on activity originally created by Matt Ehrnschwender exclusively for the IoT Village. With DEF CON 33 behind us, we’ve released this as an Extended Upskill Challenge (UCx)!
The Scenario – A router was hacked! Ruh Roh!! No problem. All you need to do is reverse engineer the flash dump of the router, find the backdoor and regain access.
The Solution – Use binwalk to extract the firmware filesystem and find a hidden pre-authentication webshell that can be found by looking at the filesystem metadata timestamps. The webshell will then allow you to run commands. Easy right? With this step-by-step mini-workshop… it is! Ready?
Just Hacking Training (JHT) is proud to be sponsoring the IoT Village for the entirety of 2025! Now that DEF CON is behind us, we’re thrilled to release 2 IoTV exclusive activities to the rest of the world…

What’s an Upskill Challenge (UC)?
A Free Upskill Challenge is a bite-sized lesson from the JHT Team, our courseware developers as well as “friends” of JHT. They are meant to be short and to the point. UCs focus on a single tool or concept and are helpful in quickly providing useful skills that might be prerequisites for other types of educational content on the platform.
A UC is only 10 – 30 minutes of student time and have no VMs. There are quizzes at the end to make sure that the content is understood.
What’s an Extended Upskill Challenge (UCx)?
To accommodate more detailed topics and virtual environments, JHT has released a new product, the Extended UC (or UCx). A UCx can be 30 – 120 minutes of student time, include VMs and videos, and an optional Capstone Challenge. A UCx is a Name Your Price item with $0 as the lowest accepted cost. That’s right… FREE!
What do I get?
Students get their own virtual environment to get hands-on experience with the tools and techniques taught in the course. It is also web-based, so you need nothing else other than a computer and Internet access.
Prerequisites for “UCx – Router Ruh Roh”
UCs and UCxs assume no knowledge at all! They’re meant to be completely self-contained, so all of the answers are in the lesson. No outside research is required.
