Twente Hacking Squad

The Twente Hacking Squad (THS) is a team of UT students & PhD students interested in computer security. We meet every Monday from 19:00 to 21:00, during which we try to improve our hacking skills. In our meetings we occasionally give workshops where we share our hacking expertise with each other in various areas such as:

  • Cryptography
  • Forensics
  • General programming skills
  • Reverse engineering
  • Pwning
  • Web hacking
See the Workshop Schedule below for an overview of dates for each workshop. In other meetings, we solve challenges from old CTFs (capture the flag competitions) and related problems to get hands-on practice to improve our hacking skills. As a team, we also participate in these CTF events from time to time.

Workshop Schedule

During the spring semester of 2022, we organize weekly CTF training sessions every Monday 19:00-21:00 in Spiegel 3 and can also be joined online*. These training sessions are open to all students from the University of Twente, but a background in computer science is highly recommended. We aim to have these sessions in a hybrid format, but, depending on the rules and regulations regarding COVID-19, we may have to fall back on online workshops. Below, we give an overview of the planned workshops.

*See the THS slack channel for the Zoom link to join.
