Ethical-hacking

This is the start of my Ethical-hacking for-fun side prosjekt(s). I want to get a better understanding about nettwork and a more hands-on approach to learning security by writing my own tools instead of using build-in tools in kali. This repo should not be used outside of educational purposes. Any malicouse use of my code is strictly prohibited. This is purely a fun and educational side project and should only be used internally against your own machines or machines that you have permission to test on.

Before you start:

Make sure you have scapy installed. pip install scapy. Make sure you have netfilterqueue installed. pip install netfilterqueue

Usefull commands:

• echo 1 > /proc/sys/net/ipv4/ip_forward - This will turn on ip_forwarding, allowing you to be MiTM
• iptables -I FORWARD -j NFQUEUE --queue-num 0 - Puts all forwarding packages into a que so that they can be modified or sniffed. I If you are testing this locally, change the chain from FORWARD to output and input. NB: remember to flush your iptables when you are done. iptables --flush

SSLstrip

A lot of these tools are based on being MiTM. MiTM are not very effective if the connection is encryped. For now, using SSLstrip (prebuild tool in kali) is the easiste fix. I will write my own SSLstriping tool at a later date. Here are some notes about how to use SSLstriping with the given MiTM tools.

1. Run the MiTM tool of your choice. In this github repo, the ARP spoofer is easy to use if you are on the same nettwork as your target.
2. Start SSLstriping with the command sslstrip
3. Change your IPtables so that the data from your target goes through port 10000 (the default port sslstrip is listening to)

iptables -t nat -A PREROUTING -p tcp --destion-port 80 -j REDIRECT --to-port 10000 4. Run whatever program you want to use on the unecrypted connection

Network Scanner

Does an ARP Request to scan the nettwork for potensital targets. Fetches IP and MAC addr

How To Use It

• Run the code and add the -t or --target flag, followed by the IP range that you want to scan. For example: python3 nettwork_scanner.py -t 10.0.2.1/24

Mac Addr Spoofer

Changes the MAC addr of the computer

---

ARP Spoofer

Spoofs the ARP table

Function

This program poisions the ARP table by abusing the ARP protocol. Given the IP of a target and the IP of the gateway we will send an ARP response poisioning their ARP tables by doing the following:

• The target will overwrite their ARP table swiching the gateways MAC addr, with out MAC addrs. Routing all traffic to the gateway, to us.

• The gateway will overwrite their ARP table switching the targets MAC addr, with out MAC addrs. Routing all traffic intedned to the target, to us.

  How To Use It

• To be able to be Man in the middle, we need to allow data to flow through our system with port forwarding(Linux). echo 1 > /proc/sys/net/ipv4/ip_forward

• To run the code use the main() function. This takes two inputs, a target_ip and spoof_ip. The target IP is the IP of our target. The spoof IP is the IP of the gateway that we are pretending to be.

  TO-DO

• Target IP and spoof IP needs to be inputs not hardcoded.

Packet Sniffer

Analyses packages from a target (use ARP Spoofing tool). Scans for potential username and password and fetches the URL of the website the login info is typed into. Does not work on a secure connection (obv...)

How To Use

Run the program and it will start sniffing incoming packages on port 80 (http). It checks for potensial username/password/email field. 

---

DNS Spoofer

Spoofs the DNS record of the target (attack needs to be MiTM. Use ARP spoofer). If the target goes to a defined webiste, he will be redirected to the kali machines local host)

---

File Interceptor

Detects when the target is downloading a file. Currently only detects .exe. It allows the attacker to replace the file that the target wants to download with a file from another website.

TO-DO:

- Add a filter that changes multipal file types with 
- Swap the file (redirect) from winrar download to my own local webserver that hosts a molicious file
- Add packages to the iptable by default instead of running the command manualy

NOTES:

  This tool uses iptables to put the packages in a que. The code looks at the que and modifies the packages. 
  When you are forwarding packages (f.eks MITM) use the following command:
  iptables -I FORWARD -j NFQUEUE --queue-num 0
  To test locally. Change the chain from FORWARD to OUTPUT and INPUT.
  NB: remember to flush your iptables when you are done. iptables --flush
  
  User of the program needs to install netfilterqueue (pip install netfilterqueue) to run the program.

Execute_command

Small programs that executes diffrent code snippets. used to test malware-ish payloads to steal passwords etc.

Steal_wifi_password

Steal all wifi information (including passwords) on windows PC and sends it to a given email. Change the send_mail("","",results) with your email(currently set to work with gmail) + password.

download_execute_and_report

Downloads a file, exetues it and sends the data to your email. Currently downloads & executes https://github.com/AlessandroZ/LaZagne/releases from a local webserver. You can start your own webserver in linux with service apache2 start. Files can be added here: /var/www/html/
