BARRA

Burn After Reading: A Shadow Stack with Microsecond-level Runtime Rerandomization for Protecting Return Addresses

Requirement

Ubuntu 16.04, pip, wllvm, gcc-multilib, g++-multilib, git

barra@ubuntu:~$ sudo apt install python-pip
barra@ubuntu:~$ sudo pip install wllvm
barra@ubuntu:~$ sudo apt-get install gcc-multilib g++-multilib
barra@ubuntu:~$ sudo apt-get install git

How to Build

barra@ubuntu:~$ mkdir -p src
barra@ubuntu:~$ cd src
barra@ubuntu:~/src$ git clone https://github.com/sheisc/BARRA.git

Suppose BARRA is installed in /home/iron/src/BARRA. Then please use gedit to open /home/iron/src/BARRA/R4/env.sh and set the environment variable R4PATH to /home/iron/src/BARRA/R4 (i.e., export R4PATH=/home/iron/src/BARRA/R4). Then you can build BARRA as follows.

barra@ubuntu:~/src$ cd BARRA/R4
barra@ubuntu:~/src/BARRA/R4$ . ./env.sh 
barra@ubuntu:~/src/BARRA/R4$ ./build.sh

How to Use

1. Download and intall VMware Workstation Player 15.

The free version is available for non-commercial use.

2. Download the compressed image of our virtual machine Ubuntu16.04.vmx and uncompress it.

Ubuntu16.04(Password_123456).tar.bz2

3. Use VMware Workstation Player 15 to open the uncompressed virtual machine Ubuntu16.04.vmx.

The password to login is 123456

(1) Figure 7 in our paper (A "Hello World" example is given in ~/src/BARRA/R4/example).

Please search .unsw.randomval in the file ~/src/BARRA/R4/example/demo.instr.s for some of the instrumented assembly code 
shown in Figure 7(d).
The instrumented data section shown in Figure 7(e) is contained in ~/src/BARRA/R4/example/unsw_addr.s.
Due to the requirement for anonymity, we manually rename some variables in our paper:
   .unsw.retaddr.bak => all_ret_addrs,   .unsw.randomval => BAR_randval,  .unsw.retaddr => BAR_mtable.
UNSW is the abbreviation of University of New South Wales.

barra@ubuntu:~$ cd ~/src/BARRA/R4/example
barra@ubuntu:~/src/BARRA/R4/example$ . ../env.sh 
barra@ubuntu:~/src/BARRA/R4/example$ make CC="wllvm"
barra@ubuntu:~/src/BARRA/R4/example$ ${R4PATH}/tools/barra.sh demo

(3) Table 3 in our paper

barra@ubuntu:~$ cd ~/src/BARRA/R4
barra@ubuntu:~/src/BARRA/R4$ ./Table3.sh

(4) Figure 10 in our paper (see ~/src/BARRA/R4/Fig10.png)

Please open 4 terminals, enter the directory ~/src/BARRA/R4/echo, 
and then follow the instructions as shown in ~/src/BARRA/R4/Fig10.png

barra@ubuntu:~$ cd ~/src/BARRA/R4/echo
