hi bro, congrats on completing the box. I have user kyle on the box. For root I know I need to reverse the authenticator binary. Currently, rusk binary is kicking my ass. I did reverse it using ghidra and know the IV and key (may not be in right order) but beyond that I am totally stuck. i will appreciate a big nudge. I tried angr as well but that fails with std::out_of_range error.
