A more thorough explanation:

Definition: An indirect attack is a type of attack that is not aimed directly at the target but rather at something related to the target. It is also known as a collateral attack.

Example: A hacker may launch an indirect attack on a company by targeting its employees with phishing emails. The employees may unknowingly give the hacker access to the company's network, allowing them to steal sensitive information or cause damage.

Explanation: In this example, the hacker is not directly attacking the company's network but rather using an indirect method to gain access. By targeting the employees, the hacker is able to bypass the company's security measures and gain entry into the network. This illustrates how an indirect attack can be just as effective as a direct attack.
