: Look for a specific point where your input is compared against a hardcoded (but encrypted) string. 💡 Key Insights for Solving : Locate the main loop in the runner
: If you have the runner binary, use GDB or Ghidra to set breakpoints at the instruction dispatcher to see values in real-time. 💡 Key Insights for Solving : If you
: Most .anom challenges use a loop to XOR your input with a key stored in the bytecode.
: Use strings or a hex editor to look for magic bytes or custom opcodes.
Custom VMs usually implement basic operations. You must map the hex values in the .anom file to their logic:
