Rowhammer demo attempt

This is an attempt to implement a rowhammer attack on a binary.

Compile

Use make to compile all

How it works

• rowhammer.cc: Will check for vunlerable memory regions by hammering random pages
• hammer.cc: Tries to allocate a space close to given binary pages and hammers everything within it
• dumbp.cc: Produces very large binary that could be used as a test target binary

hammer 1 /path/to/dumbp will try a rowhammer attack on dumbp binary by allocating 1 GB of memory (hopefully next to it).
It uses mmmap to allocate this space with the binary first page as an address hint see http://man7.org/linux/man-pages/man2/mmap.2.html.
