How to Avoid Cryptojacking?

Cryptojacking is the unlawful mining of cryptocurrencies on another person's computer. Hackers do this by convincing the victim to click on a malicious link in an email that downloads crypto-mining malware or infecting a website or online advertisement with JavaScript code that executes automatically once loaded in the victim's browser. In any case, the crypto mining malware continues to operate in the background while unaware victims use their computers regularly. The only indication they may see is slower performance or execution delays.

When and How Did Cryptojacking Begin?

Cryptojacking gained popularity in 2017 during the growth of the well-known cryptocurrency Bitcoin. Coinhive also debuted during this period, and this was a Javascript-based crypto jacking service. Simply put, Coinhive's goal was to provide website owners with an "opportunity" to earn more money from their website visitors.

Numerous website proprietors rushed in, believing that this method of crypto-mining was simpler, had more resources, and offered a much superior alternative to sponsored advertisements. The service could not function without the approval of visitors and website owners. However, Coinhive quickly began incorporating harmful malware. The objective was to attack the websites' primary weaknesses, draining resources secretly and mining bitcoin for them.

While Coinhive has been decommissioned, clones and scripts of the program remain online, exposing several additional websites to the risk of cryptojacking.

How Do Cryptocurrency Mining Systems Operate?

To illustrate how cryptocurrency mining works, let's examine Bitcoin transactions. A crypto miner checks the validity of a cryptographic transaction. The miner receives money by validating a set of transactions known as a "block." Each of these blocks contains one megabyte of data. To earn Bitcoin, users may need to validate only one transaction. On the other side, this may imply that consumers would be required to authenticate 1,000 bitcoin transactions. This varies according to the transaction's complexity and data content. When an individual verifies a block, it is added to the digital blockchain.

Another way to look at crypto mining is that Bitcoin compensates miners with Bitcoin for their verification work. They can invest in it or use it to make online payments.

What are the Risks Associated with Cryptojacking?

While cryptojacking is not as visibly disruptive as other types of malware or hacking, it still has a variety of consequences for device owners. When infected with crypto-mining malware, your computer or phone may function slowly and be unable to do routine operations. At the same time, impacted servers may struggle to keep up with normal requests.

Constantly running your computer at high speed may also waste more energy, perhaps increasing your power bill, and will wear down your electronics more quickly than normal. Additionally, if your computer has been hacked by cryptojacking software, it may be left vulnerable to additional, potentially more severe, and destructive attacks.

How to Protect Yourself from Cryptojacking: Tips & Tricks

Although detecting cryptojacking on your computer system is challenging, there are several precautionary actions you may take to safeguard your computer and networking systems, as well as your crypto-assets:

Educate Your IT Staff

Your information technology staff should be taught to recognize and prevent cryptojacking. They should be alert to the initial indicators of an assault and take prompt action to explore further. Multiple cyber security training courses are designed to help you train your IT staff.

Educate Your Staff

IT teams must rely on workers to notify them when machines become sluggish or overheat. Additionally, employees must be trained on cybersecurity by cybercrime courses online, including avoiding clicking on links in emails that execute cryptojacking code and downloading only from reputable sources. The same is true for personal emails sent from your device.

Utilize Anti-Crypto Mining Add-ons

Scripts for cryptojacking are often installed in web browsers. Utilize browser extensions such as miner block, No Coin, and Anti Miner to block crypto miners throughout the web.

Utilize Ad-Blocking Software

Cryptojacking programs are frequently placed in web advertisements. By utilizing an ad-blocker, malicious crypto-mining malware may be detected and blocked.

JavaScript Should be Disabled

When accessing the web, deactivating JavaScript can help prevent your machine from being infected with cryptolocker malware. Bear in mind that deactivating JavaScript will disable a large number of functionalities required for surfing.

Cryptojacking may appear to be a very harmless crime, as the only thing stolen is the energy from the victim's computer. However, computer resources are used for this illicit purpose without the victim's knowledge or consent to benefit criminals who generate income unlawfully.

To mitigate the risks, we recommend that you follow sound cybersecurity practices, study cyber security and install reputable cybersecurity or intranet security on all of your devices.
