[SCCC] [sddxcnews] FYI: Protection Agaisnt Hacked Wi-Fi Transmissions

[Dr. Howard S. White]

Don't use a laptop.   Use an iPad's 4G connections.  Much more secure and usually much faster than the hotel connection.

Slightly off-topic:

Since my last ATT/Yahoo email account hijacking while on travel, using a hotel's unsecured wi-fi, I have done some research and discussed the problem with others more knowledgeable than I.

I use GoToMyPC, a secure remote log-in to my office computer. GTMPC has a feature called "one-time passwords" for travel, which issues a list of password keys that you use one at a time when you log-in, so if anyone captures that P/W, it is invalid if they try to use it the next time. But even using my secure GoToMyPC connection to the secure ofc computer isn't much protection if I send over it the log-in info for the secondary ATT/Yahoo account over a hotel's unsecured wi-fi. It's still easily readable by hackers.

Best suggestion I've heard so far is to use my iPhone (or any smartphone or Blackberry) as a modem hard-wired to the travel laptop or iPad, so you are transmitting over your secure (I hope) data network rather than hotel's unsecured wi-fi.

And good advice is that when making hotel reservations, make sure they have a secure wi-fi, protected with not general but specific passwords-- you know, the kind where they print out a specific, discrete, alpha-numeric password for each guest when he checks into the hotel. (But I've read up on this, and it is amazingly easy with open source software for a hacker to decrypt any of these wi-fi router passwords in a few seconds.)

Anyway, email hijacking aside, if your travel communications are important and need to remain confidential, it is worth it to take additional security measures to increase communications security.

I know there are many others of our ham groups who know a lot more about this. If anyone has specific information on how to effect better communications security, especially on travel, please speak up.
