fq-pyrdp

fq format for parsing PyRDP replays.

In progress.

How to use the format

Get the codebase

You will need Go >= 1.17 installed. If present, clone the fq repository:

$ git clone git@github.com:wader/fq.git
$ cd fq

Add the format

Then add the pyrdp format to the import list at format/all/all.go:

_ "github.com/wader/fq/format/pyrdp"

And also to the constants at format/format.go:

        PYRDP               = "pyrdp"

Now that the format was added to the list of available formats, the actual code needs to be copied or linked in the format/ directory. Here's how you can do the later (as it can be updated independently):

$ cd format/
$ ln -s /the/path/to/fq-pyrdp/pyrdp pyrdp

Build

To build fq with the new format added just go to the root of the fq repository and use make fq. That should create an fq binary in the same directory with the new PyRDP replay format added.

Development

To enable this repository to resolve the fq code and reduce warnings, the configuration of a Go workspace is recommended. To do so, at the root of this repository, type:

go work init
go work use ./path-to-fq

Run tests

In the fq repository, run:

go test ./format -run TestFormats/pyrdp

Testing won't work with format/pyrdp as a symbolic link to this repo so you will need to copy the files to test.

fq usage

To parse the replay files using fq you will need to specify the format using -d and a query, just as you will do with jq:

$ ./fq -d pyrdp '.events[]' /the/path/to/replay.pyrdp

More complex information can be extracted depending on the PDUs that the pyrdp format can parse. For example, we can get the password used by the user that connected to the RDP service:

$ ./fq -d pyrdp '.events[1].client_info|{password:.password,username:.username}' /the/path/to/replay.pyrdp
{
  "password": "admin",
  "username": "administrator"
}
