RFID/NFC Basics - A Pentesters Perspective

I’ve did a presentation on the basics of RFID/NFC from my (a pentester) perspective. Since several parties were interested, I gave the presentation twice, once at the “Gulaschprogrammiernacht” in Karlsruhe and once at the “IT-Sicherheitskonferenz“ in Stralsund. The main goal was to explain how some of the RFID/NFC technologies work and what security issues there are. Read more

It aims at providing a better understanding of why pentesting is important and souled be done for cars. The general theme of the talk is “improving security by breaking it”. Read more

Of Mice and Keyboards: On the Security of Modern Wireless Desktop Sets

Together with my college Matthias Deeg I’ve done some research on several modern wireless desktop sets. All of the manufacturers claim they are secure because they encrypt data using AES 128. All keyboards and mice use a proprietary communication protocol (not Bluetooth), therefore we were interested in if they are really secure. The result of the analysis was presented at several IT security conferences including Ruxcon in Melbourne, Hacktivity in Budapest, ZERONIGHTS in Moscow, DeepSec in Vienna and in Luxembourg.

Security Analysis of the Student Card

The “Gulaschprogrammiernacht” (GPN) is a congress organized by Entropia e.V. (CCC Karlsruhe). I presented my research about the security of the student card at this congress. The similar student card system is present at most German universities. At this point in time the system was very broken, mostly because of the usage of the insecure MIFARE Classic RFID tags.
