What are some of the attacks on Wi-Fi?
What will be an ideal response?
Home users face several risks from attacks on their insecure wireless networks, such as:
* Reading wireless transmissions. Usernames, passwords, credit card numbers, and other information sent over the Wi-Fi network could be captured by an attacker.
* Injecting malware. Because attackers might access the network behind a firewall, they could inject Trojans, viruses, and other malware onto the user's computer.
* Downloading harmful content. In several instances, attackers have accessed a home computer through an unprotected Wi-Fi network, downloaded child pornography to the computer, and then turned that computer into a file server to distribute the content. When authorities traced the files back to that computer, the unsuspecting owner was arrested and his equipment confiscated.
