just be aware that someone
COULD be seeing what you're
You don't want to connect to
your bank and enter your
password/ transfer some
money for example.
Actually, visiting a bank on the net is the safest type of site to use
from a public place, because financial institutions always encrypt the
data sent and received.
The encryption is automatically set up between your browser and the
bank's webserver. The level of encryption is believed to be virtually
unbreakable. This means that even if someone is "sniffing" your data
by intercepting the WiFi radio signal without being a part of the
network or using a man-in-the-middle attack or other exploit, he would
be able to see everything you do EXCEPT your encrypted (i.e. banking)
There IS a danger to banking online that is rarely discussed, but it
has little to do with public WiFi: Keyloggers. These are tiny programs
that log all your leystrokes and email them to the bad guy. If you
type your password, 123456, when it leaves your computer it will look
like garbage data, but the "123456" key presses you made will be
logged to the leylogger.
Keyloggers can be easily installed without your knowledge as any virus
or worm. One hopes your anti-virus SW will catch them, but A-V SW is
not 100% effective. Keyloggers scare me, and I don't do any online
banking for this reason.
