Clipboard Virus Software To Hack Bitcoin From Computer

Clipboard Virus Software and How It Works

Looking for clipboard virus software for your cryptocurrency transactions? If you are, then you are just at the right place.

In this article, I am going to show you how to use very simple but very harmful crypto-malware to take over the control of a victim’s clipboard.

What is a Clipboard in cryptocurrency?

The clipboard is a buffer that is used for storing temporary data a crypto user has copied. When you click the “copy” button, it is actually an indication to your computer to store the data you want to copy, to this particular buffer. After a short while, when you “paste” those data, you are given another command to your computer to recall those data from the buffer.

This is now way different from the “copy and paste” we do virtually every day using our phones and computers.

Description of a clipboard virus software

Clipboard virus is a virus software that changes Bitcoin addresses. It changes any Bitcoin address that has been copied to your payment address.

With the software, the attacker gains total control over the victim’s clipboard and replaces its contents with their own data, such as a link to a malicious Web site.

The attack makes it impossible for users to copy anything else to the clipboard until they either close the browser or reboot the machine. Aside from the inconvenience it brings, the danger is that a user might inadvertently paste the inserted content into their browser or into online content, exposing themselves or others to malicious code.

How does a clipboard virus software work?

I will explain how this works using a scenario a very simple scenario involving three cryptocurrency users:

Let’s assume we have three Bitcoin users Chris, Eva, and a third user Eni who is a malicious user.

Chris, Eva, and Eni are Bitcoin users as they all own a Bitcoin wallet consisting of a Bitcoin address.

Now Chris wants to send some Bitcoin to Eva, maybe s payment for some services she had rendered to him and as expected, Eva has sent her address to Chris for the transaction perhaps via an email. When Chris opens his wallet and initiates the transaction by clicking on the “send” button, the wallet will demand Chris inputs Eva’s address. Now Chris is going to copy Eva’s address from the email which she has sent him. Chris copies and pastes the address, and he successfully sends the Bitcoins to Eva.

Now how does the third person, Eni come in? The whole idea of this attack is for Eni to get access to Chris’ clipboard. Once Eni finally gets access to the Clipboard using the clipboard virus software, she can take control of the clipboard and decide what data Chris should copy and paste. It could in fact be the address to her Bitcoin wallet.

How can one take control using the clipboard virus software?

With the software, she will be able to interact with the clipboard.

The Clipboard virus software has a Clipboard function, which is going to read the clipboard buffer. She will assign a variable called data, where she stores the content of the clipboard by using the copy-and-paste method.

The malicious user will go on to define an “if” condition. This “if” condition checks whether the victim has copied a Bitcoin address or not. The length of a Bitcoin address could go over 30 characters. Let’s assume it is just 30 characters. So in this condition, the malicious user will check whether the victim has copied a 30 or more character value. If the condition is true then the user will go on to use the setClipoard function.

The setClipboard function takes over the control of the clipboard and alters the data that has been stored in it. Using the copy method, the Bitcoin address is copied to the clipboard buffer, and then the paste method will paste whatever information that has been stored in the clipboard buffer.

To complete the process, the malicious user will add a while loop that will run continuously and will constantly use the getClipBoard Function.

Going back to our scenario, if we assume that Alice wants to copy and paste Eva’s address, in order to send her a certain amount of Bitcoin. When Chris goes to his wallet and pastes this address, the address which he has pasted is not actually Eva’s address but the address which has been determined by the hacker.

However, this virus software is only built on the fact that when users send a number of cryptocurrencies to other users, they don’t check the pasted address especially when they do not dedicate adequate time to follow the process through.

This means cryptocurrency users will not be a victim of such an attack if they always check and confirm the address to which they are going to send their cryptocurrencies.
