Dead Drops P2P File Sharing Spreads Around Globe

Lucas123 writes "After beginning as an art project 3 years ago in Manhattan to thwart government online spying and offer a physical depiction of our digitally-connected society, a trend of embedding USB thumb drives in walls has caught on and spread to every continent but Antarctica. Dead Drops, as the anonymous P2P files sharing network is called, now has more than 1,200 locations worldwide and has morphed as participants have become more creative in not only where they place the drives, but how they share files, including creating WiFi locations. The thumb drives, which range in size from a few megabytes to 60GB, have allowed people to share music, video, personal photos, poetry, political discourse, or artwork anonymously. Dead Drops creator, German artist Aram Bartholl, said the project is a way to 'un-cloud' file sharing."

      You are making a pretty big assumption there that what you are plugging in is actually a storage device. It could easily be a device which shows up as an HID device and plays back a macro. "Alt-F2, 'xterm', Enter, 'rm -rf /', Enter" would be pretty devastating on your secure Linux box which doesn't run anything from removable media.

      Just because it looks like a thumb drive, doesn't mean it is one!

      You are blindly trusting that something physically appearing as a "USB key" is a usb storage class device.

Or, it could simply zap your computer with a high voltage surge, potentially by drawing USB power to charge a capacitor...

    While it requires power, something like the PirateBox seems like a safer alternative. It relies on wifi, which means you don't have to be in one physical spot to use it, and you don't run the risk of pluggin your computer into something you can't see. You never know, it could be a 240 volt power line attached to that USB plug.

      I was just thinking of doing something similar with a Raspberry Pi (or other similar cheap computer, Beaglebone etc.) Add a wireless dongle, create a network that people can connect to, and allow them to add files. It would be pretty easy to set up a firewall, so they couldn't do much damage. I'm not sure what the best software would be though. It would be nice if you could allow people to upload, but not delete files, and set up some kind of quota system so that someone doesn't just fill it with junk.

      If you're running a system that is vulnerable to infected USB devices or media files, that's pretty much on you.

      Sigh.. there is no technical reason why a untrusted USB device couldnt present itself as a Human Interface Device (HID - keyboard, mouse, both, ..) and then open up a shell on your *nix box and run arbitrary shell commands.

      There is in fact concern that future USB drives will be manufactured to "phone home" using such techniques.

    How do they "load software to track who is downloading"? Do thumb drives now have the capability to execute software on their own?

    Sometimes! But let's use an easier attack. Put a thumb drive plus some custom hardware into a thumb drive case. Easy to do. The hardware enumerates as both a thumb drive and, say, a USB audio-device driver that is present on most stock Linux distributions and has a particular buffer overflow vulnerability that allows arbitrary code execution. That sort of vulnerability is reasonably common and has happened in the past. Engineering that hardware is not hard. When the system enumerates the USB audio device, it loads that driver and the driver performs setup by talking to the USB device and requesting information. The evil device sends back responses to the driver that trigger the buffer overflow and execute device-provided code.

    You could make this fairly system-independent by putting a number of fake devices in there that exercise different vulnerabilities. Or you could determine what the connecting operating system is (and what drivers it has available) by looking at how it enumerates. You can even have your device use soft reconnects to try out different vulnerable drivers. (You would have the computer-facing port actually connect to a hub. Also easy to engineer up.)

    Can that software access your files and ID you over a USB port?

    So, yes.

    Don't assume that because something looks like a flash drive, it actually is. And don't connect unknown peripherals to your computer -- they talk directly to drivers.

Anyone interested in exactly who is downloading or uploading what just has to put up a hidden camera to watch the thumb drives.

    So, interesting concept, poor execution. Now if the drives were accessible through wireless means, that would be a step towards creating a true dead-drop network. This thing as described is just a stunt. Art project? Yeah, I can believe that.
