WebCapture The Flag, CTF teams, CTF ratings, CTF archive, CTF writeups WebIt is a quite simple PRNG: it consists of two LCG combined with xor. We can guess the first few values and then attack the PRNG to recover the seed and predict next outputs. The simplest solution is to bruteforce all candidates for x, deduce y as xor of PRNG output with x and check if the numbers match.
