TEEPwn: Breaking TEEs by Experience

The TEEPwn experience provides an offensive system-level perspective and dives into the darker corners of TEE Security. It is designed with a system-level approach, where you will experience powerful exploitation of TEE vulnerabilities. The TEEPwn experience is hands-on, gamified and driven by an exciting jeopardy-style Capture the Flag (CTF).

It’s notoriously hard to secure a Trusted Execution Environment (TEE) due to the interaction between complex hardware and a large trusted code base (TCB). The security provided by TEEs has been broken on a wide variety of devices, including mobile phones, smart TVs and even vehicles. Publicly disclosed TEE vulnerabilities were often exploited directly from the less-trusted Rich Execution Environment (REE). Many of these vulnerabilities were speandcific for TEEs and required novel exploitation techniques.

The TEEPwn experience provides an offensive system-level perspective and dives into the darker corners of TEE Security. It is designed with a system-level approach, where you will experience powerful exploitation of TEE vulnerabilities. The TEEPwn experience is hands-on, gamified and driven by an exciting jeopardy-style Capture the Flag (CTF).

Your journey starts by achieving a comprehensive understanding of TEEs, where you will learn how hardware and software concur to enforce effective security boundaries. You will then use this understanding for identifying interesting vulnerabilities across the entire TEE attack surface. You will then be challenged along the path to exploit them in multiple scenarios. All vulnerabilities are identified and exploited on our emulated attack platform which implements an ARMv8 (64-bit) TEE based on ARM TrustZone.

You will take on different roles, as an attacker in control of:

  • the REE, attempting to achieve privileged code execution in the TEE.
  • the REE, trying to access assess protected by a Trusted Application (TA).
  • a TA, aiming to escalate privileges to TEE OS.
  • a TA, accessing the protected assets of other TAs.

TEEPwn will guide you into an unexpected range of attack vectors and TEE-specific exploitation techniques, which may be leveraged for novel and creative software exploits. refining your skills to a new level.

 

Deliverables

During the training we will provide you with the following:

  • cloud-based virtual machine with all the required tooling installed
  • access to the exercise modules and instructions
  • walk through videos for the hands-on exercises

We will also provide you the following in order to continue with the exercises after the training:

  • offline virtual machine with all tooling preinstalled
  • ability to copy the exercise modules and instructions
  • ability to run the exercise modules forever

 

Format

This TEEPwn experience will be given in a hybrid format where attendees are able to join in-person and online at the same time. Attendees need to select the desired format before the start of the training.

  • Option1: The in-person format requires attendees to join us on-site in Singapore for 4 days full of lectures and practical exercises. The lectures and support are provided in-person using a classroom setting.
  • Option 2: The online format requires attendees to join us online for 4 days full of lectures and practical exercises. The lectures from the in-person classroom are virtually streamed using Zoom. Support is provided virtually via Discord.

Co-Founder

Raelize B.V

Cristofaro Mune (@pulsoid) has been in the security field for 15+ years. He has 10 years of experience with evaluating SW and HW security of secure products, as well as more than 5 years of experience in testing and assessing the security of TEEs.

He is a security researcher at Raelize providing support for developing, analyzing and testing the security of embedded devices.

His research on Fault Injection, TEEs, White-Box cryptography, IoT exploitation and Mobile Security has been presented at renowned international conferences and in academic papers.

What students say about his training:

“For me as a non-SW reverse engineer the learning curve is a bit steep but better by challenged than to be bored during a training.”

“The training is AMAZING, could use a bit more coffee breaks”

“Really enjoyed the material and CTF, instructions were clear, challenges were nicely staggered, just tricky enough without being frustrating and conveyed the concept clearly”

“Thanks for organising training in Ringzer0. It is above my expectations, and I enjoyed very much these 5 days. Training content are well considered.”
