What is a potential consequence of network hijacking?

Network hijacking is a type of cyber attack where an unauthorized user gains control over a network connection. This can lead to various harmful outcomes, and one of the most significant potential consequences is security breaches and data theft. When an attacker successfully hijacks a network, they can intercept, manipulate, or steal sensitive data being transmitted across that network. This could involve personal information, login credentials, financial data, or corporate secrets.

In addition, network hijacking can enable attackers to exploit vulnerabilities further, install malware, or conduct additional attacks such as man-in-the-middle attacks, where they can monitor and alter communications between two parties. The severity of these consequences underscores the critical need for robust security measures to protect networks from unauthorized access and ensure data integrity and confidentiality.

The other options present scenarios that do not realistically align with the implications of network hijacking. Increased network efficiency and improved data encryption are not outcomes associated with cyber attacks, and increased user access rights typically refers to legitimate administrative functions, not the result of a hijack.
