Scapy Containerised

This gives you a shell inside container/namespace via TTYD, and you can use Scapy to analyse network traffic.

Scapy is a powerful Python-based interactive packet manipulation program and library.

Scapy enables the user to send, sniff and dissect and forge network packets. This capability allows construction of tools that can probe, scan or attack networks.

Scapy is usable either as a shell or as a library. For further details, please head over to Getting started with Scapy, which is part of the documentation.

Prerequisite

• Container runtime (needs to run privileged mode)
• Some Python Knowledge
• Have read Scapy docs

Installation

Follow these steps to build:

git clone https://github.com/saidsef/scapy-containerised

docker build -t saidsef/scapy-containerised:latest .

docker run -d --net=host --privileged -v /path/to/geoip2:/data saidsef/scapy-containerised:latest

GeoIP data sets can be download from P3TERX

Than visit:

http://localhost:8080

In the browser termonal type:

python -m scapy.__init__

To start Scapy in interactive mode.

Deployment

To expose host interface to container enable hostNetwork: true in deployment.yml file. Consider security implications

Make sure the PORT isn't already bound to another service - if you choose to run the service on a different PORT make sure you update the relevant fields.

HELM

helm repo add scapy https://saidsef.github.io/scapy-containerised/
helm repo update
helm upgrade --install scapy scapy/scapy --namespace scapy --create-namespace

Kubectl

kubectl apply -k ./deployment

To view, bind Kubernetes service port loaclly:

kubectl port-forward --namespace scapy svc/scapy 8080:8080

Than visit:

http://localhost:8080

Sniff Packets

To list available layers:

help(scapy.layers)

# load_layer("http")
# get_if_list()
# sniff(iface="eth0", prn=lambda x: x.show(), lfilter=lambda x: HTTP in x, count=100)

https://scapy.readthedocs.io/en/latest/api/scapy.layers.html To load layers tls you might need to downgrade cryptography <= v38

The routes are stores in conf.route. You can use it to display the routes, or get specific routing:

conf.route
