The correct choice regarding the category of the CIA triad being attacked in the scenario of discovering an unauthorized packet-capturing tool is confidentiality. The primary role of packet capturing tools is to intercept and analyze network traffic. When such a tool is on the network without authorization, it can lead to unauthorized access to sensitive data being transmitted over the network. This directly compromises the confidentiality of information, as it allows individuals who are not authorized to view or obtain potentially sensitive information.

Confidentiality ensures that information is accessible only to those who are authorized to have access. An unauthorized packet-capturing tool violates this principle by enabling eavesdropping on communications, thereby exposing private data to unauthorized users.
