Cryptojacking is the unauthorized use of a device’s processing power to mine cryptocurrency without the owner’s knowledge or consent. It is a growing problem that can have serious consequences for affected users, including reduced device performance, higher electricity bills, and potential damage to the device.

What are cryptojacking attacks?

Cryptojacking attacks are a growing concern for individuals and businesses alike. These attacks involve the use of malware to secretly mine cryptocurrency on a device without the owner’s knowledge or consent.

The malware typically works by using the device’s processing power to solve complex mathematical problems, a process known as mining.

While the attackers may benefit from these attacks, the affected individuals and businesses often suffer the consequences. Cryptojacking attacks can result in reduced device performance, higher electricity bills, and potential damage to the device. In addition, they can be difficult to detect and remove, making them a significant threat.

To protect against cryptojacking attacks, it is important to take steps to secure your devices. This includes using antivirus software, being cautious when downloading software and opening emails from unfamiliar sources, and regularly scanning your device for malware. I

CoinHive and Cryptojacking

CoinHive is a cryptocurrency mining service that allows website owners to use the processing power of their visitors’ devices to mine cryptocurrency.

This is typically done through the use of JavaScript code that is embedded in the website. When a visitor loads the website, the JavaScript code runs on their device and uses its processing power to mine cryptocurrency.

While CoinHive can be a legitimate way for website owners to monetize their content and generate revenue, it has also been used by cybercriminals to carry out cryptojacking attacks.

In these attacks, the CoinHive code is secretly embedded in a website or delivered through a browser extension without the user’s knowledge or consent.

The code then runs on the user’s device and mines cryptocurrency for the attackers.

CoinHive has garnered significant attention due to its potential for abuse. Here are some key points to keep in mind when it comes to CoinHive and cryptojacking:

1. Cryptojacking attacks can have serious consequences for affected users, including reduced device performance, higher electricity bills, and potential damage to the device.
2. CoinHive can be used to carry out cryptojacking attacks without the user’s knowledge or consent.
3. To protect against cryptojacking attacks, it is important to use an ad blocker or browser extension that blocks cryptocurrency mining scripts, be cautious when downloading software and visiting unfamiliar websites, and use antivirus software to detect and remove malware.
4. CoinHive has been the subject of controversy due to its potential for abuse. While it can be a legitimate way for website owners to monetize their content, it is important to be aware of the risks associated with it.

By keeping these points in mind, you can help protect your device from being used for cryptojacking and avoid the negative consequences of these attacks. Remember to always be vigilant and take steps to secure your device to prevent malware infections.

Conclusion

The attenuation of this type of attack is good news, but at the same time, the number of attacks on businesses has increased since the last quarter.

However, much more experience is required for this. An experienced hacker doesn’t need CoinHive … So, thanks to CoinHive, only the suckers have fallen.

In summary, the extraction of cryptocurrencies on websites does not necessarily have to be motivated by evil intentions. However, it is essential that the site visitor is warned in advance or that the mining is done illegally without his knowledge.

If you are interested in the website’s content, and the authors inform you in advance that they will benefit from your device when you visit their website, this may be a way to support the website.

Criminals will find and use any means possible to make money, and cryptojacking is a reasonably easy way for them. What is very positive is that even the manufacturers of browsers react to it and try to fight it.
