What is a potential risk when using a free and open wireless hotspot in a public location?
- Too many users trying to connect to the Internet may cause a network traffic jam.
- The Internet connection can become too slow when many users access the wireless hotspot.
- Network traffic might be hijacked and information stolen.
- Purchase of products from vendors might be required in exchange for the Internet access.
Explanation: Many free and open wireless hotspots operate with no authentication or weak authentication mechanisms. Attackers could easily capture the network traffic in and out of such a hotspot and steal user information. In addition, attackers might set up a "rogue" wireless hotspot to attract unsuspecting users to it and then collect information from those users.
