Joern Supports Binary

Joern ’s frontend family is growing, and we welcome our newest member, Ghidra2cpg ! It makes Joern the first code querying tool with binary support.

What can Ghidra2cpg do for you that other tools can’t? Well, everything you are used to doing with Joern but with assembly.

For example, you can query function content: here you can see a comparison between objdump output on the left side and the Joern equivalent on the right side.


One of the most interesting features of Joern is its data flow, which can be used with the new frontend, too. Given the following C code, you are able to track the parameter of the function test_strcpy to strcpy by defining a source and a sink.

void test_strcpy(char* x){
  char dest[4096];


Ghidra2cpg uses Ghidra to disassemble code. It subsequently translates it into a code property graph that can be queried using Joern. Choosing Ghidra as the basis for our analysis allows us to easily adapt to the growing list of processors that Ghidra already supports. However, the initial release includes support for x86 and x86_64 only. ARM, MIPS as well as P-Code are in an early stage and will be released in the very near future.

We still want to give you a small preview of the ARM support: image
