🦑Hacking- Configuring network implants based on cheap SBC single board computers :

Step 1: Download the Orange Pi Armbian disk image
After selecting all the necessary components and checking the connectivity to the target router, you can start creating a hacker machine based on Orange Pi Zero by downloading the Armbian Orange Pi Zero image from the official developers website, and if you have Kali Linux installed, then this procedure can be done using the "wget" command.

~$ wget 'https://dl.armbian.com/orangepizero/Debian_stretch_next.7z'

2) This will download the file in the 7z archive format, so to extract the Debian image, you need to install the appropriate program if it is missing by executing the command described below:

~$ apt-get install p7zip-full -V

3) Next, you need to extract the image from the archive by making the following request:

~$ 7z x Debian_stretch_next.7z

4) After that, it is worth reviewing the extracted files by executing "ls", after which the list should look at the package "Armbian_5.75_Orangepizero_Debian_stretch_next_4.19.20.img", which will be used to install Debian on the microSD card installed in the Orange Pi Zero.

~$ ls -l

5) Stage 2: Burn the image to a microSD card
To do this, you will need to insert the card into a computer with Linux Kali installed via a special microSD-SD adapter, and if this is not possible, then you will have to buy this adapter or a card reader connected via USB. After connecting the SD card, you need to immediately look at the information about it by creating a request "dmesg".

~$ dmesg

6) Now you should pay attention to the letter assigned to the disk, which in our case is "sdb2", and this will be needed to execute the "dd" command in order to copy the ".img" image file. Thus, it will remain to replace the value "X" with the desired one in the "sdX" record, after which the copying process will begin, which takes about two minutes.

~$ dd if=/path/to/Armbian_5.75_Orangepizero_Debian_stretch_next_4.19.20.img of=/dev/sdX bs=512k status=progress

7) Step 3: Connect Orange Pi Zero to Router
Next, we take the created card and install it into our mini-computer, which is not yet ready for synchronization with the router due to the lack of initial settings. As a result, you will first need to connect the Pi Zero to your router via the Ethernet port and wait about five minutes for the SBC to boot correctly and identify itself on the network.

8) Step 4: Finding the Pi Zero's IP Address
At this stage, it is quite difficult to find out the IP address of our micro PC due to the lack of a normal interface and other tools for interaction, so it would be wise to use the same computer with Linux Kali OS connected to the same router with SBC.

Here you need to enter the command "nmap" with additional keys "-T4" and "-sn" to start scanning the entire network in search of active nodes.

~$ nmap -T4 -sn 192.168.1.1/24

9) Stage 5: Connect via SSH
The default password in the new SSH shell is "1234", but it must be changed, and a new profile must be created after the first login.

~$ ssh -p 22 root@192.168.0.165

The authenticity of host '192.168.0.165 (192.168.0.165)' can't be established.
ECDSA key fingerprint is SHA256:PE6127Kvx+twOLWK90mJDUQSUggH5ujh3h8liuLCR7w.

10) Then you just need to follow the simple instructions from the terminal window. At the same time, the data for logging into the account will not be needed later, but this process cannot be ignored. When entering your data, you will need to drive in the old and new password, and the fields with the name, phone number and room number can be left blank.

Creating a new user account. Press <Ctrl-C> to abort

!1) Updating the Pi Zero
Next, you will need to update the software by running the command as described below, after which usually a few outdated packages are reinstalled. During this procedure, the connection to the Pi Zero via SSH may be interrupted, leading to the SBC freezing, and this happens due to the loading of the openssh-server and wpasupplicant modules.
