Yes!

Our labs include building your own real spectre attack against the kernel, bypassing ASLR and building ROP chains with various side channels, finding and exploiting backdoors in a RISC-V CPU by building a hardware fuzzer, and more.

(source: I designed the Spectre lab plus a few others)

All our labs are fully open source for anyone to try: https://github.com/MATCHA-MIT/SHD-StarterCode

If you give them a try, please do let us know what you think! We genuinely want these activities to be fun and approachable (we designed them like a big CTF) and welcome feedback from the community.
