OutGuess is used for __________ attack.

OutGuess is a steganography tool that embeds secret data within the redundant bits of image files such as JPEGs, allowing covert communication by hiding the existence of the message itself rather than encrypting it overtly. It is classified as a steganography attack tool because its primary function is concealing information inside an innocent-looking carrier medium.

Web password cracking uses tools such as Hydra or Burp Suite to brute-force or guess login credentials, which is an entirely different attack category from data hiding.

SQL injection exploits improper input validation in database-driven applications to manipulate queries, with no relation to steganographic data concealment.

Man-in-the-middle attacks intercept and potentially modify communications between two parties in transit, which is unrelated to the offline data-hiding purpose of OutGuess.
