Make a Physical Computer Virus: Plant a Parasite to Prank Your Peeps

by:CTECHi     2019-11-29
Computer viruses are terrible.
They are undetectable, dangerous and often operate under your nose.
For general computer users, there are very few repair options.
You can buy expensive anti-virus software, it can cause more problems than the fix, you can wipe the hard drive clean, lose all the important data, or if all the other software fails
Just switch to Linux.
But what if you can give your enemy an immortal, undetectable virus?
The virus we make today cannot be eliminated because it becomes the physical part of the victim\'s computer.
Every time your victim launches their desktop, our virus waits randomly for a while and then suddenly cuts off all the power!
A random time delay means that your roommate will feel confused about a survival crisis when writing a paper, if not for a few days.
Perfect prank.
Material step 1 understand that the relay is an assembly that redirects the physical power into the computer.
A relay contains a coil-
Like we did for X-Men Glove—
This is turned on and off via the Arduino signal.
When the Arduino activates the coil, the magnetic field generated by the current in the coil pulls a piece of metal from one contact to another, thus redirecting the current of the computer to the disconnected circuit.
When the coil is on or off, you have to play with your relay to find out which pins are the coil pins and in which direction the current flows.
Connect the wires to all pins on the relay for easy circuit board connection.
When you connect the 5 V pin on the Arduino to one end of the coil and the ground pin on the Arduino to the other end of the coil, you hear the clicking sound.
This is the sound of the magnetic coil pulling the contacts into the position.
Continue to connect the 5 V voltage and ground to all pins until you hear the sound.
Pins on the relay are not easy to insert into the breadboard.
Long jumpers help with the prototyping process.
After the coil pin is found, use the LED and resistor to test where the power supply flows around other pins.
Keep in mind that the short lead of the LED is the negative lead and must face the resistance.
Here is the relay test circuit: the red and black wires on the right bring the power and ground to the first two rows.
The red and black wires on the left start to power and ground from the top rows and put them into the coil to activate the relay.
According to the state of the coil, the yellow wire brings 5 volts into the relay to turn on and off.
The blue wire is where the 5 V voltage of the yellow wire exits the relay and is connected to the front of the LED.
When the relay is in the right position, the LED should be turned on as the power flows through the LED and then the resistance is grounded.
Once working properly, connect and disconnect the Arduino\'s power supply or ground pin multiple times.
Your light should flash when the relay clicks.
Please note that on the last board the yellow and blue wires will be attached to the screw terminals and to the computer power supply.
This means that the real circuit board will push the 120 V voltage through the yellow and green wires.
However, for the Test circuit, we use the 5 V voltage because it is very convenient.
Learn the second step of the circuit my relay has two settings.
When the coil is turned off, the current flows from the middle pin to the top pin
Left of the relay
When the coil is turned on, the current flows from the middle pin to the top-
Right pin on relay.
Using this information, I decided
The left pin will be connected to the computer and the top-
The correct pin will not connect to anything.
This way, it doesn\'t have to use power to keep the computer running when Arduino is running.
Only when Arduino wants to turn off the computer does it have to activate the coil and pull the contacts to the pin in the top right corner.
When we tell pin 13 to output 5 V, it activates the coil and moves the tiny switch inside the relay to the right.
When the coil is inactive, the switch will remain on the left side, allowing the power to flow to the computer through the spiral terminal.
By connecting the screw terminal to a power cord inside the computer, we connect our circuit board with the power supply and can control it by relay interrupt connection.
Step 3 solder the board once you understand where your relay and all the pins are, it\'s time to make the virus.
Using the prototype plate, weld the circuit according to the following figure.
The blue wire delivers power from the computer through a relay.
The red wire connects one side of the coil to the male head.
The black wire connects the other side of the coil to the adjacent male head.
The male head will be mounted on pin 13 and ground on the Arduino board.
Here we connect the board to the Arduino: the head on the left goes through the bottom of the board and connects to pin 13 and ground on the Arduino.
The title on the right is just to increase stability.
They did not make any electrical connections.
The yellow wire above passes the computer power through the relay through the screw terminal.
Note that for the yellow wired part of the circuit, you should use wires that are at least as thick as the wires you find in your computer.
They may heat up and melt the insulation if the wires are too thin.
The lower side of the plate is all welded well.
Few solder joints.
On the Arduino, pin 13 is directly adjacent to the ground.
When using a virus, make sure to put the title in these sockets.
Step 4 upload the code to insert the Arduino into the computer and open the Arduino Software.
Load this code into an empty sketch and upload it to the Arduino board.
This particular code is very simple, so we will understand the meaning of each line in the code.
Step 5 install the computer parasi once the code is uploaded, we can start hacking the victim\'s computer.
Open the computer box and find the power box.
This is where the power on the wall enters the computer.
No two computers are exactly the same, but you definitely need a screwdriver to turn on the power box.
Once entering the power supply, find the wire that is directly connected to the external power plug.
This is the vitality of the computer.
Cut off a wire from the external power plug.
Weld the two wires to the exposed end of the computer wires.
Be sure to insulation exposed wires with heat shrink tubes and electrical tape!
Turn off the power box and connect the two wires to the screw terminals on the board.
Plug in a rechargeable battery between 6 and 12 volts.
The normal 9 volt battery is unlikely to have enough current to switch the relay.
The RC battery also means that your virus will last longer.
Fix the Arduino on the computer box using velcro or tape.
Be sure to insulate the pins at the bottom of the Arduino so that they do not short-circuit the metal case of the computer.
Now, turn off the computer and put it back on the victim\'s desk.
When they work, they will find that their computer will be turned off randomly between one minute and one hour, which is for no reason or mode.
This hack can be applied to any device that has enough space to hold the Arduino board.
If you really want to be mean, you can either build a random channel selector on the TV or turn off the lights in the living room at random --
Even a treadmill.
The possibilities are endless.
