Like in recent years the popular Hacking 101 workshop will take place on TROOPERS17, too! The workshop will give attendees an insight into the hacking techniques required for penetration testing. These techniques will cover various topics:
Tavis did it again. As stated in the title it is possible to remotely execute commands via the Chrome extension for the popular meeting software Cisco WebEx. This post summarizes the most relevant information for you.
i´ve looked a bit at the Insomni’hack CTF which took place on the 21st January and lasted for 36 hours.
For the sake of warming up a bit for our Troopers workshop Windows and Linux Exploitation,
I decided to create a write-up of the first pwn50 challenge.
To grab your own copy of the presented files you can also find it in our Github repository:
I am looking forward to our newly introduced dedicated Forensic Computing Training at TR17!
We will start the first day with a detailed background briefing about Forensic Computing as a Forensic Science, Digital Evidence, and the Chain of Custody. The rest of the workshop we will follow the Order of Volatility starting with the analysis of persistent storage using file system internals and carving, as well as RAID reassembly with lots of hands-on case studies using open source tools. As a next step, we will smell the smoking gun in live forensics exercises. Depending on your preferences we will then dig a bit into memory forensics and network forensics.

The 1-day training from last TROOPERS has become a 2-day training, featuring even more real-world attacks and defenses as well as new hands-on sessions! We’ll teach you, step by step, how to spot and exploit crypto vulnerabilities, how to use the strongest forms of state-of-the-art cryptography to secure modern systems (like IoT or mobile applications), and bring you up to speed on the latest and greatest developments in the world of cryptography, such as TLS 1.3, blockchains, and post-quantum crypto.

Niklaus, Manuel and me had a great time speaking about one of the latest Tablet PCs from DPRK at 33C3 this year. Our work on RedStar OS from last year revealed a nasty watermarking mechanism that can be used to track the origin and distribution path of media files in North Korea. We have seen some interesting dead code in some of RedStar’s binaries that indicated a more sophisticated mechanism to control the distribution of media files. We got hands on a Tablet PC called “Ul-lim” that implemented this advanced control mechanism.
In this post I’ll discuss configuration approaches for systems which usually have been configured with “static” IP parameters in the IPv4 age/context (like servers in data centers). When it comes to IPv6 there are more options and we’ll have a look at their implications and potential advantages/disadvantages.
We had to make some tough choices regarding our TROOPERS17 Main Conference Agenda. Thank you again to everyone for submitting! The full agenda will be published later this week, but for now here are the next round of talks!
Fuzzing is a very old technique to find bugs and vulnerabilities in software. However it has seen a new push in recent years due to vastly improved tools. The compilers gcc and clang have received Sanitizer tools that allow finding a lot of bugs like use after free errors and out of bounds reads that are otherwise very hard to find.
