“I think this research opens a few big security questions. Who is responsible for the router that is hosting the Wi-Fi spot, has the end user done all they can to ensure that default passwords are changed and their device has not been compromised, and has the owner of the router been fully informed on how to opt-out if they so wish? Generic logins and open Wi-Fi spots are a breeding ground for malware. Mobile security is becoming a much bigger concern with more and more devices getting bigger not just in storage size but also in physical size, this means we need to look at mobile security sooner rather than later.
Often the end user does not see a mobile device as a security hazard in the same way their desktop, but if you were to log time spent on each you would probably find the mobile wins. Operating system updates and application updating is part of your desktop life but when was the last time you checked your mobile phone to see if the software could be updated?
Virtually everything we do these days requires internet access. We strive for 100% coverage and often will look at internet availability before anything else, and that enforces the need for increased security. Free WIFI is great for keeping up with Facebook or email but the amount of information being exchanged is frightening. Virgin Media having recently introduced free Wi-Fi at 150 of the London's underground stations, and they state that more than 3TB of data are consumed every day."
