What can happen if a spyware program steals a cookie?

• A. It can improve internet browsing speed
• B. It can lead to unauthorized access to accounts
• C. It can fix software bugs
• D. It can change system settings

Answer: (B)

When a spyware program steals a cookie, it can lead to unauthorized access to accounts because cookies often contain session information and preferences related to a user's online accounts. Cookies are used by websites to remember users and their login states; if a malicious actor gains access to these cookies, particularly those tied to authentication sessions, they can impersonate the user. This means they could potentially log in to the user's account without needing the user's credentials, exposing sensitive information or enabling various types of online fraud.

While other choices may involve impacts on a computer or its functionality, they do not directly relate to the consequences of a cookie being stolen by spyware in the same way as unauthorized account access does. Thus, the key concern with stolen cookies revolves around account security and privacy risks, aligning with the chosen answer.
