The practice of “malicious cryptocurrency mining,” often known as “cryptojacking,” includes a duplicitous internet scam. Its objective is to use another person’s computer or laptop to mine for digital currency like Bitcoin (BTC), among many others. In essence, these online intruders—known as cryptojackers—hack your device and use its processing power to mine cryptocurrency. Yet why? As was previously said, bitcoin mining is the main objective of cryptojacking. Let’s briefly explore the idea of Bitcoin mining to acquire further knowledge.

Strong computers, specialist equipment like mining rigs, adequate electrical supply, a reliable Internet connection, and appropriate software are all needed to enter the world of collecting digital currencies. Cryptojackers’ main goal is to mine cryptocurrency using the computing power of their victims’ equipment or devices.
This method enables hackers to gain access to the priceless resources required for mining virtual money without the victim’s knowledge or agreement. Even more troubling is the fact that cryptojacking is not limited to computers. Along with hacking into personal computers, cryptojackers may also do the same on mobile devices like smartphones and tablets, as well as other Internet-connected household items and servers.
What are the types of Cryptojacking attacks?
In-browser JavaScript Code
This attack tactic, often known as “drive-by cryptocurrency mining,” focuses on computers by injecting malicious JavaScript code onto a webpage. Devices that access the hacked website are quickly susceptible to cryptojacking, which turns them into equipment for illegal Bitcoin mining. It’s important to remember that not all in-browser mining techniques are bad in the context of cryptocurrencies. According to some sources, this strategy has been applied for financial gain in many industries, including the gaming and content development sectors.
Malware Scripts
Malware attacks function similarly to phishing scams in that they use malicious links that, when clicked, redirect to hacked pages to collect sensitive information. When a link carrying malware is clicked in the context of cryptojacking made possible by malware scripts, an automatic download of harmful code onto the victim’s device begins. Cryptojackers now can start the mining operation on the compromised device after successfully installing the code.
Ways to Detect Cryptojacking
- Unusual Slow Response: Cryptocurrency mining is a complex operation that uses a lot of your device’s computer power. You can notice an odd slowness in your computer’s response as a result, even when conducting routine tasks.
- Device Overheating: You might notice a slight change in your computer’s temperature during cryptojacking because complex and auxiliary activities are taking place in the background.
- Spike in CPU Usage: Look for hints in the functioning of your machine. The increase in your computer’s Central Processing Unit (CPU) consumption while viewing websites with little media content is a solid indicator. If this happens on your device, there’s a greater chance that cryptojacking malware has infected it.
Ways to Prevent Cryptojacking
- Be careful of malicious links and emails: Phishing scams and other nefarious schemes that rely on harmful links are common in the world of cryptocurrencies. As a result, it is crucial to have a thorough understanding of these strategies and how to avoid them. Exercise caution when dealing with suspicious emails; avoid clicking on them right away to lessen the chance of getting infected with malware.
- Ensure that your web filtering tools are consistently updated: Maintaining a constant, if not higher, level of safety while you browse is ensured by routinely updating your filtering software.
Stay informed about incidents, news, and trends related to cryptojacking: Make it a point to regularly stay informed of any new information regarding this illegal behaviour. Keeping up with recent news and advancements in the field of cryptojacking will surely give you insights into how it develops and practical methods for avoiding its effects.
