Hello!

My name is Kyrollos and this is the first small "program" that I'm publishing

This is a tool that blocks Censys, Shodan, Shadowserver, PAN Expanse, and DigitalOcean.

Most of these are tools that find vulnerabilities in your Computer/VPS network. I recommend using these tools first to ensure that your system is safe from attacks. After you're satisfied with your system vulnerability, You can use the tool I provided to block these tools from connecting to your system. Please keep in mind, some tools have a history check in place so it won't be completely invisible but it will block new searches.

--- Updated Method: Powershell (Requires no download, just one line of code) ---

1. Please run PowerShell as Administrator
2. Copy and Paste the line below and hit enter

Old Method: Download (Still works but not necessary)

• To Block, please install the zip file and run block_scanners.bat
• To Unblock, please run unblock_scanners.bat from the same zip file

This was created for Windows and has been tested on Windows. You may edit your own copy to your liking.

Linux:

One-liner:

curl -s https://raw.githubusercontent.com/Kyro25/Scanner-Blocker/refs/heads/main/block_scanners.sh | sudo bash

Manual install:

1. Save the file (block_scanners.sh)
2. Make it executable

chmod +x block_scanners.sh

3. Run it

sudo ./block_scanners.sh

By using -I (Insert), we ensure these "DROP" rules sit at the very top of the chain, stopping the traffic before any other rules allow it through.
