For that to work the hospital's SSID would have to be open as well. And if that were the case, faking the SSID would be a complete waste of time because you could just connect to it yourself.
- zurn 12y agoYou vastly overestimate the difficulty of spoofing a password-protected wifi network. Even without that, acquiring access credentials is hardly rocket science. (eg. grab one of these pumps or any other wifi device lying around and read the password over the ethernet/serial port)
- hueving 12y agoI don't think you understand how wpa works. It's not like the client just sends a password. A shared key is mutual authentication. If putting up a network with a target ssid leaked data, WiFi would be completely broken.
- zurn 12y agohttp://www.renderlab.net/projects/WPA-tables/ http://www.renderlab.net/projects/WPA-tables/ wifi security is a pretty soft layer of additional security and definitely should be considered cheaply penetrable for purpouses of defense. But like I said you can just harvest the PSK off a device without cracking anything. An unprotected shared secret on all nodes is not very secret at all.
- hueving 12y agoA link to some precomputed tables doesn't mean anything. Wpa2 AES CCMP with a long shared secret is effectively unbreakable. I have not seen any research on academia or industry that comes close. Care to share some? If not, please stop spreading misinformation.
