What is memory-dumper

memory-dumper is a tool for dumping files from process's memory. The main purpose is to find patterns inside the process's memory, which is done by plugins, and dump segments of memory to files.

Why would I use memory-dumper

Virtually memory-dumper can dump anything, it's up to you find it any use. That said, I use it to dump Flash files (SWF). There are many SWF encrypted files that can't be decrypted easily. The only easy way is make them decrypt themself and them dump them directly from memory.

New plugins for dumping any other type of data can be created easily.

How do I compile it?

You'll need meson, python3 and ninja-build. Once you have those, just run:

mkdir build
cd build
meson ..
ninja

How do I use it?

Go to the build directory and run:

sudo ./memory-dumper -p PID

to dump the memory of a process (sudo is required because memory-dumper must read the memory of a process that doesn't own)

or

./memory-dumper -p /path/to/file.ext

to dump the content of a file.

Ok, I'd like to dump XYZ file

You just need to create a plugin! It's that easy. Just look inside the plugin folder. Your plugin should have two main functions. The first one is init which will be used to init the plugin itself and pass it some useful functions; and the second one is match, which is used to pass a memory block to the plugin so it can search and dump it's content.

TO-DO:

  • Currently memory-dumper works only on Linux. Maybe I'll port it to Windows at some point in the future, but I don't want to promise anything. Anyways, I'll accept a patch for this :)

  • I'm planning to write some more plugins. If you want a plugin for some specific file type, use the New issue button :)

  • Write some documentation about how to write a plugin.
