Ok, ok, I give up (don't really have the time). Just 2
* PDA's are NOT common devices for average end users.
* The security of 802.11b is pretty much easy to hack
and the best is: You don't need a physical connection
to the network.
The difference here is: The network is not the destination
but can be the source for starting hacks.
This opens a lot of opportunities for security breaches...
maybe while Curt sits at MosBurger and enjoys his meal,
his notebook sends out thousands of SPAM mails to us poor
DoCoMo users. If DoCoMo traces this down to MosBurgers
network they can only shake their heads who did it and how.
Or he uses other IP services like VoIP.
The German Chaos Computer Club once went to the Expo2000
where somebody installed around 20 industrial robots who
were programmed to follow a specific 'choreography'. These
robots were connected via a 802.11b network and the guy was
able to take over control pretty fast. This was kind of
dangerous, since industry robots out of control can kill.
A network consisting of cables is as much easy to hack, you
just need anyhow physical access (inductive access is good
enough) to a single cable and some packet recording tools.
Wireless networks are more insecure, because they send the
(encrypted) packets through the air and you don't need any
physical access anymore, but can trace the network traffic
totally anonymous and with the right tools it's "easy" to
install a "machine in the middle" and take over control.
Ok, it's not as easy, but it's possible. The few times I was
involved with wireless networks, the person who set it up
made major mistakes and it was accessible for everybody. If
they than work with Windows or Mac...goodbye, security.
Information for beginners of this topic can be found here:
They also inform you almost in realtime that for example
this Japanese site was just hacked: http://www.kunimedia.co.jp/
Anyway, I am hungry now and follow Curt to MosBurger (not).
Juergen <-- uses network cables.
