Cryptocurrency mining has become increasingly popular in recent years. It involves using powerful computer systems to solve complex mathematical equations and verify transactions on a blockchain network in exchange for cryptocurrency rewards. However, some individuals and groups are turning to a new technique known as “cryptojacking” to mine cryptocurrency without the victim’s knowledge or consent. In this blog, we will discuss what is cryptojacking, tools and techniques involved, and how you can protect yourself from it.
What is Cryptojacking?
Cryptojacking is the unauthorized use of someone else’s computer or device to mine cryptocurrency. Hackers achieve this by infecting the victim’s computer or device with malware that uses their processing power to mine cryptocurrency. This is done without the victim’s knowledge or consent, and the victim is left with a slow and sluggish computer or device.
Tools and Techniques Involved in Cryptojacking
- Malware: Hackers use malware to infect the victim’s computer or device. This malware can be delivered via phishing emails, social media links, or through compromised websites.
- Browser-based Cryptojacking: In this method, the hacker infects a website with a script that runs in the background of the victim’s web browser. The script uses the victim’s CPU power to mine cryptocurrency, without the victim’s knowledge.
- Remote Access Trojan (RAT): In this method, the hacker uses a RAT to gain remote access to the victim’s computer or device. Once they gain access, they install mining software that uses the victim’s processing power to mine cryptocurrency.
How to Protect Yourself from Cryptojacking?
- Keep your software and antivirus up-to-date: Cryptojacking can be prevented by keeping your software and antivirus up-to-date. This will ensure that your computer or device has the latest security patches and is protected against known vulnerabilities.
- Use ad-blockers and anti-cryptojacking browser extensions: Ad-blockers and anti-cryptojacking browser extensions can prevent malicious scripts from running in the background of your web browser.
- Be cautious of phishing emails and suspicious links: Do not click on links or download attachments from suspicious emails. If you receive an email that appears to be from a reputable organization, verify its authenticity before clicking on any links or downloading attachments.
- Monitor your CPU usage: Keep an eye on your CPU usage. If you notice that your computer or device is running slow or is using an unusually high amount of CPU power, it may be a sign of cryptojacking.
In conclusion, cryptojacking is a serious threat that can slow down your computer or device and compromise your security. By following the steps outlined in this blog, you can protect yourself from this threat and ensure that your computer or device remains secure.
