1. Install Dependencies (Ubuntu)

    ~$ apt install -y git wget gcc build-essential automake python gcc-multilib
   

2. Download Valgrind

    ~$ tar jxvf valgrind-X.X.X.tar.bz2
    ~$ cd valgrind-X.X.X
    ~/valgrind-X.X.X$ 
   

3. Git clone sensegrind

    ~/valgrind-X.X.X$ git clone https://github.com/matte6288/sensegrind
    ~/valgrind-X.X.X$ cd sensegrind
   

4. Run build_taintgrind.sh (to build valgrind, taintgrind and Capstone)

Compile with

~$ ../sensegrind$ gcc -O0 -g -o test test.c

Run with

~$ ../sensegrind$ ../build/bin/valgrind --tool=taintgrind  --taint-stdin=yes test

or simply

~$ ../sensegrind$ ../build/bin/taintgrind --taint-stdin=yes test

You will need to save STDERR output from your taintgrind run to a file the easiest way to do this: ../taintgrind$ ../build/bin/taintgrind --taint-stdin=yes test 2>log.txt

You will also need to get all variable from the c file:

~$ python cparser.py -f test.c

Then run logSenseParser.py to get dot file for visualization and retrieve potentially sensitive variables:

~$ python logSenseParser.py -v var_names.txt -l log.txt

Most likely you will want to write doto output to file like this:

~$ python logSenseParser.py -v var_names.txt -l log.txt > test.dot

Visualise the graph with

~$ sudo apt install graphviz
~$ dot -Tpng test.dot -o test.png

Or, for larger graphs

~$ dot -Tsvg test.dot -o test.svg
