MITM Attack on EVCS Systems

Step 1: Set Up Virtual Machines

Choose two Virtual Machines (VMs):

  • VM 1: Runs the EVCS.py script (Electric Vehicle Charging Station).
  • VM 2: Runs the CSMS.py script (Charging Station Management System).

Step 2: Modify EVCS and CSMS Scripts

**EVCS Script (EVCS.py)

  1. Open the EVCS.py script.

  2. Locate the __init__ function.

  3. Modify the self.host attribute to point to the CSMS VM's IP address:

    self.host = "<CSMS_VM_IP_ADDRESS>"

**CSMS Script (CSMS.py)

  1. Open the CSMS.py script.

  2. Locate the __init__ function.

  3. Modify the self.host attribute to bind to all network interfaces:

    self.host = "0.0.0.0"

This allows it to accept connections from any IP address.

Step 3: Set Up Kali Linux for MITM Attack

Enable IP Forwarding

Open a terminal in Kali Linux and run the following command to enable IP forwarding:

echo 1 | sudo tee /proc/sys/net/ipv4/ip_forward

Verify that IP forwarding is enabled:

cat /proc/sys/net/ipv4/ip_forward

If enabled, the output should be 1.

Configure Ettercap for ARP Poisoning

  1. Open Ettercap GUI in Kali Linux.
  2. Scan the network to identify the IP addresses of the EVCS VM and CSMS VM.
  3. Assign:
    • EVCS VM IP → Target 1
    • CSMS VM IP → Target 2
  4. Start ARP Poisoning on the targets.
  5. Begin capturing and analyzing the communication between the two VMs.

Conclusion

By following these steps, you can intercept and analyze the communication between an Electric Vehicle Charging Station and its Management System. This allows you to study potential vulnerabilities and explore security improvements.
