Cryptojacking is a practice that refers to the unauthorized use of a person's computer device to mine cryptocurrency. This article emphasizes the need for individuals and businesses to increase their cybersecurity measures to protect themselves from this growing and hidden cyber threat.
Understanding Cryptojacking
Cryptojacking is a practice in which an individual or group of individuals utilizes another person's computer device without permission to mine cryptocurrencies, such as Bitcoin or Monero.
This practice is often carried out using malware that is infiltrated into the target system through various methods, such as unauthorized downloads or exploiting security flaws.
Once infected, the computer device will be used for crypto mining without the owner's knowledge, which can result in reduced system performance, high power consumption, and hardware damage.
Cryptojacking methods
Cryptojacking uses a variety of methods, with two common approaches.
The first involves trojans, malicious programs that are secretly installed on computers via deceptive links or email attachments. These programs run on the host device, draining resources for the hacker's benefit.
The second method is known as “drive-by” cryptojacking, using malicious JavaScript code on web pages that are compromised or controlled by hackers.
Signs Cryptojacking Has Occurred
The impacts of cryptojacking are very serious, some of which include increased power consumption, slowed computer performance, and shortened equipment life.
Recognizing these signs is important. Users may notice reduced performance, overheating, and intensive fan usage. Modern antivirus software providers provide protection against cryptojacking.
Cryptojacking Vulnerable Devices
Cryptojacking exploits a variety of devices - computers, servers, smartphones - obtained through malicious emails, websites or online advertisements that contain links to automatically executed malware.
The two general types are file-based and browser-based. In the first, the hacker sent a seemingly legitimate email with an attachment running a crypto mining script. In the second, malicious code embedded in the website triggers a script when the victim accesses the infected site.
Fast and Undetectable Spread
These schemes often go undetected, allowing hackers to mine without control, charging victims high electricity costs and earning token rewards without consequences. Cryptojacking scripts can cause lag or damage the device due to use.
Some scripts have worming capabilities, and can quickly infect multiple devices and servers on a network.
Tips to Prevent Cryptojacking
- Use Anti-Malware Software. Use trusted anti-malware and antivirus software with special features to detect and block cryptojacking attempts.
- Regular software updates. Regularly update operating systems, browsers, and security software to fix vulnerabilities that cryptojackers can exploit.
- Be Careful with Email. Avoid clicking on links or downloading attachments from unknown sources, as these could be a vehicle for cryptojacking trojans.
-
Educate yourself and those closest to you. Provide education and training to employees, emphasizing the risks of clicking on unknown links and the importance of cybersecurity hygiene.
-
System Performance Monitor. Monitor your computer's performance for signs of unusual activity, such as increased CPU usage , overheating, or decreased performance.
Conclusion
In a digital landscape increasingly haunted by cyber threats, cryptojacking is a hidden and persistent threat. As revealed in this article, the methods used by cryptojackers vary widely, from trojan infiltrations via deceptive emails to “drive-by” attacks on compromised websites.
By adopting these preventative measures and increasing cybersecurity awareness, individuals and businesses can contribute to building a more resilient defense against the rising tide of cryptojacking, ultimately preserving the integrity of the digital ecosystem.
