A growing and silent threat in the world of cybercrime is crypto jacking. This is a type of cyber attack where hackers use the processing power (cpu/gpu) of another person's smartphone, computer or server to secretly mine cryptocurrency. In this process, the device owner does not realize that someone else is using his electricity and device without his knowledge. This technique is mainly used to mine proof-of-work (pow) cryptocurrencies like Bitcoin or Monero (xmr).

How does it work?

Crypto jacking is carried out mainly in two ways: Hackers send mining scripts or viruses to the user's device through various malicious links or under the guise of a legitimate app. Once downloaded, it runs in the background all the time. As soon as you enter a particular website, the JavaScript code there is activated. As long as you keep that website open, your computer will continue to mine crypto for the hacker. It is not a persistent virus, but it works as long as the browser is open.

How do you know if you are infected?

There are some specific signs to recognize crypto jacking. First, if your device suddenly becomes very slow or hangs, this is a big sign. Second, if the device's fan rotates with an unusual noise and the computer overheats. Third, if your electricity bill suddenly increases and you go to the task manager and see that an app or browser is using about 80-90% of your CPU, then you are definitely a victim of crypto jacking.

Means of prevention

To avoid crypto jacking, it is important to take some precautionary measures. Always use a good quality anti-virus that can detect mining scripts. You can use extensions like 'NoCoin' or 'MinerBlock' in the browser that block malicious scripts. Also, avoid clicking on suspicious links or downloading files from unfamiliar websites. In the case of offices, it is possible to detect unusual traffic using a network monitoring system.

Conclusion

In short, cryptojacking is a form of modern digital parasitism. While it doesn't directly steal money from your wallet, it does put you at risk of financial loss by shortening the life of your device and increasing your electricity bill. Since cybercriminals have a lower risk of being caught using this method, they are using it more. Being aware of your internet usage and regularly checking your device's health can protect you from these invisible mining attacks. Remember, awareness is the best defense against digital security.
