How to use Ngrok for remote access
SayCheese is a tool that can be used in Termux to capture images from a targeted device remotely. It generates a malicious HTTPS page using Serveo or Ngrok Port Forwarding methods, and a javascript code to cam requests using MediaDevices.getUserMedia. Ngrok is a port-forwarding platform that allows the sharing of specific ports (HTTP, TCP, and UDP).
Now, here is a step-by-step instruction on how to use Ngrok for remote access:
Firstly, you will need to install the Ngrok agent on your edge gateway or remote device/service. You will need an Ngrok account and an API key. You can create a bot user so that you can create an agent authtoken independent of any user account.
Next, you will need to define all required internal endpoints inside the Ngrok configuration file. You can install Ngrok and its configuration file in /path/to/ngrok/ngrok.yml and the executable in /path/to/ngrok/ngrok. If there is no edge gateway present in your network, you must configure each agent on each device with an internal endpoint for that device.
Now, to create a tunnel from your local host to the internet, you will use a single command. Open a new session in your Termux and copy and paste the following command:
Curl -X POST \
- H "Content-Type: application/json" \
- D '{ "name": "ssh-session", "proto": "ssh", "addr": "10.1.1.50:22" }' \
Https://agent.example.com/api/tunnel
You can now access your cloud endpoint at tcp://5.tcp.ngrok.io:23028. You have now built a secure network to access any and all remote services using TCP and RDP.
You can also use Ngrok to replace complex SSH/RDP chains and VPNs. With Ngrok, you can create secure and dynamic access to remote services or sites with a single agent.

How to generate a malicious HTTPS page
SayCheese is a tool designed to remotely capture images using a target's webcam. It uses a phishing attack methodology by generating a malicious HTTPS page and prompting the target to allow access to their camera. Here is a step-by-step guide on how to generate a malicious HTTPS page using SayCheese in Termux:
Step 1: Install SayCheese
Open your Termux application and enter the following command:
Apt-get update;apt-get upgrade;apt install git php openssh;cd;git clone https://github.com/remo7777/saycheese.git;cd saych*;bash saych*.sh
This command will install the necessary packages, clone the SayCheese repository from GitHub, and run the installation script.
Step 2: Choose a Port Forwarding Method
After running the script, you will need to choose a port forwarding method. SayCheese typically uses Ngrok or similar tools for port forwarding. Ngrok is a secure tunnel for exposing local servers to the internet. You can install Ngrok by running the following command:
Pkg install wget wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-arm.zip unzip ngrok-stable-linux-arm.zip
Step 3: Generate a Malicious HTTPS Page
Once you have installed SayCheese and chosen a port forwarding method, you can generate a malicious HTTPS page. SayCheese will use the chosen port forwarding method to create a public URL that connects the target's browser to your local Termux environment.
Step 4: Send the Phishing Link
SayCheese will provide you with a phishing link, such as `https://example.ngrok.io`. Send this link to your target via email, message, or other platforms. The page will use a JavaScript code to prompt the user for permission to access their camera.
Step 5: Capture Images
Once the target clicks on the link and grants camera access, SayCheese will instantly capture images via their webcam. These images will be saved in the SayCheese directory on your device.
It is important to note that the unauthorized use of SayCheese is illegal and unethical. It is intended for educational purposes or ethical hacking with permission. Always obtain consent before testing someone's security, as misuse can lead to serious legal consequences.
