Hacking a Bluetooth Printer Server: GATT to UART Adapter?

Thu, 12 Mar 2026 00:00:00 +0000

This blog post describes the journey of how we discovered an interesting Bluetooth SoC within the Datong NP330, a Printer Server IoT device. Our initial goal was to reverse-engineer and analyze the Bluetooth controller that is included in the device. So we wanted to be able to dump the firmware or, if possible, get shell access on the printer server. During that journey we found a few vulnerabilities that ultimately let an attacker fully compromise the device. This is possible over Bluetooth or network via unauthenticated remote code execution with root privileges.

This blogpost contains summaries of talks from this year’s TROOPERS18 Attack & Research Track.

Reverse Engineering Blackbox Systems with GreatFET & Facedancer by Kate Temkin and Dominic Spill

USB is everywhere, your phone, gaming consoles, IoT waffle irons, you name it. Due to its’ widespread use in everyday life it is typically trusted by the user. And even if one wanted to find out what’s happening behind the scenes, surely digging into USB communication is too much of a chore to be worth the hassle, right? This talk by Kate Temkin and Dominic Spill are about to prove that very wrong with an impressive display of their tools GreatFET and Facedancer.

Blackhoodie at TROOPERS18

Fri, 02 Feb 2018 00:00:00 +0000

We are thrilled to announce the Blackhoodie event at Troopers 2018 on March 12th and 13th in Heidelberg. This time it is going to be a 2 day workshop with various interesting topics related to reverse engineering. We will make sure that you get some hands on experience with reversing and more.

As always, one of the main motivation for Blackhoodie is bringing more women into reversing.
So we would like to see more women apply to the training slots. However, we are open to everyone who would like to apply. We do have a very limited number of seats at this training site. So we apologize in advance if we can’t accommodate everyone, even though we wish we could! Please apply before “February 20th” and we will contact you regarding next steps.
