I’ve recently got into CTF for the learning and fun. To those who don’t understand the attraction, just think of it like a puzzle, crossword or sudoku for hackers. I’m posting my solutions to various CTFs, but I’m excluding the actual answer or flag in most cases. I figure if you are truly stuck and Googling, you’ll find a solution somewhere, so why not here? But I’ll make you at least do the work once the method is figured out.
