# shellcode_hashes

shellcode_hashs was created inspired by a [script of the same name in flare](https://github.com/fireeye/flare-ida/tree/master/shellcode_hashes).   

Find the name that matches the [hash](https://www.fireeye.com/blog/threat-research/2012/11/precalculated-string-hashes-reverse-engineering-shellcode.html) used in the shellcode.  

Use the database created by flare script.

## sqlite2json.py

Since Ghidra could not import sqlite, I created a script to convert it to json.  

Convert with the following command:

```

python sqlite2json.py

```

## shellcode_hash_search.py

Open the target shellcode and execute the script.
