What is Cryptojacking and How To Prevent It

Cryptojacking is a type of cybercrime that has been around for a few years.

It involves exploiting user’s bandwidth and processing power to mine cryptocurrencies without their knowledge.

The process is taxing on users’ devices, router, and servers.

As a direct result victims experience overheating, the slowdown of devices, and higher electricity costs.

There are Two Types of Cryptojacking

Filed Based Cryptojacking

Hackers attack users by getting them to click on malicious links that load a mining code onto their devices.

The code can hack into GPU and CPU devices, which they can then use to mine cryptocurrencies.

Hackers leave little evidence behind and it’s extremely difficult to identify the perpetrators.

Browser-Based Cryptojacking

Browser based hijacking is becoming a more common method of cryptojacking.

This method involves hackers identifying vulnerable websites and hiding malicious code on them, often unbeknown to the owners.

When the browser is open the user becomes the processing power for the mining.

The mined cryptocurrency is deposited directly into the account of the attacker.

The cost of mining, electricity, and computer wear and tear becomes the user’s problem.

Reasons for Increase in Cryptojacking

Cryptojacking is seen as an easy and efficient way to generate an income with relatively no effort.

Hackers simply have to install code onto the website.

As a consequence, many victims are slow to act as they don’t fully understand the risks and expenses associated with cryptojacking.

Cryptojacking detection is difficult as it is a particularly stealthy form of hacking.

That’s why most users don’t notice their devices performing more slowly, overheating, or the added electricity bills.

When victims do eventually notice, many fail to make the connection to cryptojacking.

How to Prevent Cryptojacking

Cybersecurity experts recommend the use of strong passwords, to download apps and software carefully, and block anything that looks malicious.

In addition, to prevent vulnerabilities, anti-Virus software and Windows software should be updated frequently.

Anti-mining extensions such as, minerBlock, block cryptocurrency miners all over the web.

As they serve to not only block flagged requests and scripts but can also detect potential mining behavior inside loaded scripts and kills them immediately.

Conclusion

Cryptojacking is continuing to see a rise, especially, in-browser trafficking.

Moreover, due to the nature of the attack, many victims remain unaware.

Some individuals would argue that the theft of processing power is a victimless crime.

However, this argument does not take into consideration the damage mining could do on the victims’ devices due to the high usage of processing power.
