It's a cool idea, but I worry about malware. Malware is known to be able to infect USB drives put into the machine it's on, and it only needs to be plugged into another machine to infect it. They'll have to be systematically reformatted pretty often...

I don't think it's a big deal for people running linux!

It is a bad idea to plug untrusted hardware into your computer. Many Windows users have autorun enabled, so could be infected with malware as soon as they plug it in. This has been exploited by people pretending to run promotions and handing out infected USB drives in front of targeted businesses.

Worse than autorun, there have been buffer overflows against USB drivers and proof-of-concept exploits that allowed Firewire devices to read arbitrary physical memory through DMA access. I haven't seen this used in practice, but the risk is there. Bruce Schneier wrote about these attacks a few years ago: http://www.schneier.com/blog/archives/2006/06/hacking_comput...

If you want to go down the Ken Thompson "Trusting Trust" hardware security rabbit hole, think about who manufactured your computer.

Neat idea. Obvious security concerns apply, but probably people who are nerdy enough to whip out their laptop and plug it into the wall are smart enough not to have autorun switched on when doing this.

Would also make a neat Kickstarter project.

You think incorrectly and having that assumption, you're exposing yourself to more risk. To assume Linux USB drivers, file systems and file managers don't contain vulnerabilities is to assume wrong.

This was the first and only thing I thought about when reading the article.

The idea is "neat" but completely impractical and extremely dangerous.

Zzzzz. Old spare computer with no network connection, DVD burner, done.

Well, less people target Linux as less use it. If I hooked up to one of these, though, it'd have to be with an isolated partition or in Haiku.

Fun concept, but I immediately imagine someone going around smashing these with a hammer (or, perhaps more likely, city workers being sent out to remove them). :\ Here's a much more expensive project with a similar idea: http://torrentfreak.com/kiosk-of-piracy-an-offline-copy-of-t...

Bluetooth low energy is option once more phones support it. With a button cell the transmitter will operate more than a year. Hide it completely in a wall or somewhere else where it is difficult to remove.
