The application uses block-based encryption (typically AES/CBC) and reveals whether the decryption was successful (specifically, if the padding was correct).

Compute a MAC over the ciphertext and the IV using a separate, independent key. Append the MAC to the payload. hacker101 encrypted pastebin

One user, "Lulzmaster", hinted that the password might be related to a recent lecture on steganography. Ethan revisited the lecture notes and re-watched the video, searching for a hidden clue. hacker101 encrypted pastebin

Because the encryption happens entirely on the server side, the client never sees the encryption key. However, the way the application handles error messages and structures its data blocks opens the door to a devastating cryptographic attack.
