Ettercap

Ettercap is a network security tool used to monitor, analyze, and intercept data passing through a network. It allows users to observe traffic between devices, identify potential security issues, or perform authorized testing. Primarily, it performs "man-in-the-middle" attacks, where it secretly positions itself between two communicating parties to capture or modify the data exchanged. While useful for network diagnostics and security assessments, it can be misused for malicious purposes. Therefore, its use should be ethical and authorized, ensuring the privacy and security of all network users are maintained.
