The concern of confidentiality primarily revolves around ensuring that sensitive information is not accessed or disclosed to unauthorized individuals. A replay attack directly impacts confidentiality by allowing an attacker to capture and resend valid data transmissions, potentially exposing sensitive information or manipulating a session without the knowledge of the parties involved.

In a replay attack, the attacker intercepts a legitimate message being transmitted over a network and later replays it to deceive the system into thinking it is an authorized user. This can lead to unauthorized access to confidential data, thus undermining its confidentiality.

While other attacks like brute-force and phishing can affect security, their primary implications lie more in the realms of authentication or data integrity, rather than directly breaching confidentiality. Denial-of-Service (DoS) attacks disrupt services and affect availability more than they compromise the confidentiality of information.
