Comments on: Handhelds Might Be a Security Risk

vnunet is quoting Security consultants @stake who point out that Palm handhelds are vulnerable to having passwords stolen from them wirelessly. @stake has written an app that takes advantage of the Palm's ability to HotSync via its infrared port. Notsync tricks a Palm into thinking it is connected to its owner's PC, rather than a hacker's PDA. The hacker then downloads the target's password.

While this simple app doesn't try to grab any other information off the target Palm, it is a fact that many people use the same password for everything, including accessing secure corporate networks.

Well put

However I think the major problem is that to integrate smth like a public/private key system into hotsync isn't feasable due to the fact that the Palm processors are only 16-20 MHz and this form of encryption is rather processor intensive.

Also if Palm supplied 128 bit (or higher) encryption into it's IR functions then it couldn't export them out of Canada and the US so you can't really blame them for not trying.

128-bit encryption is exportable...

Only as secure as practices.
After my going to a palm-related
show and finding I had acquired 50
new contacts, I set my "beam"

door).

Keep it on you

My palm is only a security risk when they pry it out of my cold, dead fingers. If you keep it with you at all times, and have a cover that obscures the IR port, this new trick is easily prevented.

This seems as rather a non-issue. Unless I am mistaken, and someone please correct me if I am, you must initiate a hot synch from the Palm or its cradle. No one is going to be able to surreptitiously come up to you and steal your data without your active [and ignorant] involvement. While it (sounds) feasible that you could trick a Palm into thinking it was synching, the above exploit would require a series of events and a setup that is just plain unlikely...

Lets get real

Putting this in perspective, the risk is only if you Hotsync by IR and I think most people who do this might just spot someone standing less than a metre away pointing their Palm at you while you sync.

Bluetooth

OK, it may seem crazy now. But just wait for when Palms come Bluetooth enabled, or 802.11b enabled. Automatic, wireless, transparent networking with any other deivce within 10 meters that it can find. With the current state of Palm security, that's a big neon "hack me" sign.

So maybe people should find other places than their Palm to store sensitive data!! Otherwise someone will have to develop VERY good encryption or security software. Maybe if Palm made it impossible to transfer memos etc., when they are marked private.
Anyone Know if this would be possible?
