WebBean Counter. The flag was in an encrypted PNG file with AES-ECB, as StepUpCounter was initialized with step_up=False, IV wasn’t updated during encryption.Considering the plain text is a PNG file, the header is known, the key size is 16, so use the first 16 bytes of cipher text to xor the first 16 bytes of PNG header to leak the key. WebThis page offers a convenient way for you to interact with the challenge functions. You can also use GET requests to send and receive data directly from the listed routes/endpoints if you wish.
