January Get Fit Reversing Challenge

This post introduces an educational reverse engineering challenge centered on a custom virtual machine named EvilGroupVM, asking participants to determine the bytecode file format, recover the nine-instruction opcode set and their effects on runtime memory, and create a self-modifying bytecode sample that prints a name, with an optional task to reimplement the VM in C; it provides suggested tools, basic usage instructions, and links to training material and challenge files.
