RE: Controlling specific USB devices on Windows XP

Hi,

I took a quick look at UDRW (your first link). It looks like this needs
to install its own drivers which would require user to be local
administrator on the computer. I don't believe you can secure the
computer as long as users are local administrators -- well maybe we can
still use epoxy glue to fill out USB ports ;-) ... anything else local
admins will be able to bypass...

Unless the USB device emulates a cd-rom:

Another poster sent me this. It's someone try to perform the "hack"
himself. See the second entry:

http://hackaday.com/


I may not be well versed in this topic, but my logical assumption that
if there was a way for windows to tell the the difference between a USB
cd-rom and a USB removable storage device, there had to be a way to fool
windows in to thinking a USB removable storage device was a cd-rom. So
wondering if it had been found yet, lead me to try a simple google
search that find the first url.

Thanks for the info, but most folks are already aware that be default,

the AutoRun function is enabled for CDs, but disabled for removeable
storage. A simply query on TechNet supports this:

Well, I don't have a USB storage dive handy at the moment, but I
grabbed the closest CD I knew had an autorun.inf, the second I open
the drive in Explorer, the open=setup.exe line excutes and I have
setup.exe executing. Does seem to hard to get it to run
without user
knowledge.

Given the recent social engineering test with
USB devices
left around
a credit-unions lobby I would disagree.

That "test" is suspect, as it doesn't provide
nearly enough
information. By default, Windows does not parse
the "load="
or "run=" lines of an autorun.inf file from
removeable media.
So, the question is, what about the "test" got
the users to
run the Trojan on the USB devices?
