This script will detect if SSH has inadvertently been exposed to the outside world.
It would be neat if my wireless access point could bridge directly to my cable modem so that clients would have proper public IP addresses. Being directly connected to the internet significantly increases vulnerability so the aim is to address this with a bridge firewall.
This is an experimental script I made to store encrypted TFA credentials in the cloud. It uses GPG to protect the the uploaded data. The tokens can be accessed anywhere on anything that has access to the GPG key.
The script, using only Bash, will scan common ports, and if an open port is found, it will display a base64 encoded output of the servers response.
This tutorial will demonstrate how to create reactive firewall rules. If a device attempts to communicate with known malware command-and-control servers, the potentially compromised device will be added to a blacklist, and its internet access will be immediately disabled.
In this tutorial, we will use a cheap usb modem to send SMS messages over the internet. It can be accessed via a Web GUI or command line
