You can find the open source release of challenges and other code used in the 2020 Hack-a-Sat Final in this repository: hackasat-final-2020.
The subfolder qemu-vm contains instructions and patches to compile and launch QEMU for the satellite architecture.
The binaries given for the Finals are also present so that it is possible to replay some of the Finals challenges.
In addition, a python-gdb plugin for RTEMS 5 is provided to help debugging. Specifically, it helps developping the exploit to solve Chall3 from the Finals.
The subfolder scapy-space-packets provides an implementation of the CCSDS Space Packet Protocol using Python and scapy.
Using a command line interface, it enables communicating with a satellite without the hassle of having to find where to click on a GUI interface.
It can directly connect to the satellite via a Unix socket or TCP port, or using the COSMOS router port.
Parts of the infrastructure we used during the final event and for the preparation phase are available in the infra subfolder.
A list of acronyms can be found in acronyms.md.
