Challenge Text

  • Given an objdump of an executable, figure out what hexadecimal instructions are needed to nop to get the jctf flag to stdout

Hint

  • The Intel Manual might be overkill, but maybe reviewing Intel Assembly and their corresponding opcodes might help to crack the challenge. Simply enter the opcodes

Solution

  • Follow the Control Flow to Determine what opcode you have to nop
  • Flag: jctf{7e0a}
