SLOTSCREAMER is an inexpensive device configured to access memory and IO, cross-platform and transparent to the OS - all by design with no 0-day needed.
The open hardware and software framework that we will release will expand your NSA Playset with the ability to tinker with DMA attacks to read memory, bypass software and hardware security measures, and directly attack other hardware devices in the system. 

Under development - to be presented at DEFCON 22

Attack system software (drivers and scripts, to be released)
Attack Device (pre-built device to be disclosed)
Target system software (just kidding. there isn't any! just plug and NSA-play!)

1. Insert Attack Device into a PCIe slot on target system
2. Connect Attack Device to Attack Host
3. Run magic software
4. Win!
