Flag format: uiuctf{...}

This challenge contains 5 handouts:

  • README: This file.
  • chal_build: The files used to build the challenge. You can use this to build another copy of the challenge but the binary layout is not guaranteed to remain the same.
  • edk2debug.log: EDK2 debug log during boot as seen on IO port 0x402.
  • edk2_artifacts: EDK2 OVMF build artifacts containing debugging symbols of each UEFI module.
  • run: Pre-built files in case you want to run the challenge locally. This is the same copy of the challenge running on the server.

I also bundled gcc per popular request from 2022. Apologies for the size of the handle bundle. The disk contains kernel module headers in /usr/src/linux-headers and you may build modules from within.
