I discovered rather inadvertently that laptops do not enjoy having their USB VCC shorted to GND one bit. It is a sure DoS, in fact if the machine has a stupid power supply, it could result in permanent damage. It is kind of scary for kiosk machines like the those ubiquitous Kodak photo centers. I give you, the usb pwner. It could even hide inside a legitimate stick: USB Pwner schematic VCC ------------ D+ ---(nc) | D ---(nc) | GND ------------ -- Todd Troxell http://rapidpacket.com/~xtat _______________________________________________ Full-Disclosure - We believe in it.
