What could have happened to Femke while connected to a rogue access point?

When connected to a rogue access point, one of the significant risks is that the rogue access point could intercept, manipulate, or modify data transmissions, including form submissions made by users. This can occur because a rogue access point is typically set up to capture information without the user’s consent or knowledge.

In this scenario, if Femke submitted sensitive data through a form while connected to the rogue access point, an attacker could modify the information being sent, potentially leading to unauthorized access, data theft, or fraudulent activities. This risk underscores the importance of using secure connections, such as Virtual Private Networks (VPNs) or encrypted websites (HTTPS), to safeguard against such attacks while using public or untrusted networks.

The other choices do not directly relate to the security implications posed by a rogue access point in the same critical way as the modification of form submissions, which can have dire consequences for user data security. For instance, the laptop's battery life, automatic software updates, or presumed faster connections do not illustrate the immediate security threats that arise from interacting with a rogue access point.
