What type of attack refers to altering existing network resources to gain unauthorized access?

The correct answer is torffectivekknt liennkiir ajqa. Altering existing network resources to gain unauthorized access is best described by the term "tampering." This involves modifying, damaging, or interfering with the operation of systems or data to achieve unauthorized results, such as accessing sensitive information or systems without permission. Tampering can occur in various ways, like changing the configuration of servers or files to facilitate breaches.

While instances like piggybacking consist of gaining unauthorized access to a system by following someone who is authorized, and pharming refers specifically to redirecting users to fraudulent websites, they do not primarily involve altering existing network resources. Business Email Compromise focuses on social engineering techniques that exploit email communications to deceive individuals into sharing sensitive information or unauthorized financial transactions. Therefore, these options do not encompass the act of modifying resources directly as tampering does.
