One possible scenario: - Have a USB drive with a few tools on it. - Have an auto-run configured to run pwdump and dump the SAM to the USB drive
Hello everyone, In order to put some 'practice' on this attack, I ve been trying this night to effectively use autorun mechanisms and see what could be possible. After reading the MSDN specs about autorun.inf file creation, I added an autorun.inf into my USB device along with a little batch script whose purpose was to copy the 'SAM' table and copy of the 'SET' command result into a specific folder on the usb device. Nothing happens... Even after being sure auto-run is enabled. Something should be missing... are there specific operating systems that disable auto-run by default ? (I am using windows 2000) However, burning the batch + autorun file onto a cd-rom and inserting it into the tray makes the auto-run sequence loading... So 2-cents question: which os'es do really use USB devices auto-run and on which USB devices does it work ? (not a usb hard-disk key it seems)... -- Antonio Fontes Couche 7 Stratégie de communication et sécurité Web http://www.nxtg.net/couche7 Refs: Creating an auto-run enabled application http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/shell/programmersguide/shell_basics/shell_basics_extending/autorun/autoplay_intro.asp
