Cryptojacking – what is it and how can you prevent it?
With cryptocurrencies more popular than ever before, cybercriminals have come up with a new revenue model that allows them to extract a lot of money from their wallet. We call this phenomenon cryptojacking. But what exactly is cryptojacking and how can you prevent it? That’s what we’re going to talk about today!
What is Cryptocurrency
Does the name Bitcoin or Ethereum mean anything to you? These are two crypto coins that millions of people have added to their crypto wallets.
Cryptocurrencies are stored in a large network of computers that perform cryptographic calculations 24/7. These cryptographic calculations ensure that the digital currency cannot be changed and is also safely stored. One thing is certain, the cryptocurrencies stored within this network cannot be broken and more importantly, cannot be stolen.
Each cryptocurrency stored within the network has its own password. Only with this password will you get access to your cryptocurrency as the owner. For example, if you want to make a transaction with your Bitcoin, which is increasingly possible these days, you enter your password and you can pay.
Cryptocurrency can be compared to ‘real’ money. The coins do not ring in your wallet but are stored in a computer network.
This is how crypto mining works
Cryptocurrency is stored on the blockchain, a database in which all transactions are recorded. We call this technology blockchain technology.
If “normal” money is deposited into your account, only you can see those amounts. No one else has access to this information. Cryptocurrency works a little differently. All registered transactions on the blockchain are visible to everyone. So it’s no secret how much cryptocurrency you own!
What is striking about crypto transactions is that they crypto transaction does not go through a bank, but through a computer network. We call the computers responsible for crypto transactions miners.
A crypto miner converts crypto transactions into (data) blocks, which are then added to the blockchain. This only happens if the transaction has been properly hashed. To do this, the computer has to solve all kinds of complex mathematical calculations.
Cryptominers do not work for free. They are paid with cryptocurrency. You will not receive cryptocurrency for every transaction. You will only be rewarded with a large number of transactions. You don’t have to do anything yourself for this. While you are lounging on the couch, your computer works overtime day and night to generate income. Nice and easy!
Cryptojacking – what is it and how does it work?
The more crypto miners crack the computer brain to solve complicated mathematical calculations, the less a crypto miner can earn from this hard work. A limited number of cryptocurrencies are released to crypto miners.
Nowadays, to earn nice pocket money from the work of your computer, you can no longer get started with a simple laptop. For that, you have to buy well-developed hardware and let this hardware be incredibly expensive. Hackers have come up with the perfect solution to this problem, which we know as cryptojacking.
Cryptojacking involves hackers hijacking thousands of other people’s computers to do the work for them without the burden on them. You often do not realize that a hacker is carrying out a cunning plan with your computer because this process takes place in the background.
Hackers can make huge profits by putting your computer, and those of others, to work, while your energy bill skyrockets because of all the work your computer does. We can say that cryptojackers are criminal crypto miners.
Different ways of cryptojacking
A hacker can cryptojack in several ways, two to be exact. This increases the hacker’s chance of success, while you as a victim have to take even more measures to protect yourself against cryptojacking.
- Cryptomining scripts in the browser First of all, a hacker can cryptojack by placing a piece of malicious code on a web page. Once the website loads, the piece of code will run by itself. From now on, your device will act as a crypto miner without your knowledge as long as the web browser is open.
- Crypto-malware Malware is a collective term for various types of malicious software. Crypto malware is also malware. Hackers have several tricks to install crypto-malware on your computer. For example, hackers send a phishing email that contains a link or file. If you open the link or file, crypto-malware will be installed on your computer and your computer will act as a crypto miner.
