The rise of digital currencies such as Bitcoin and Ethereum has brought about a new form of cyber-attack known as "cryptojacking." In this tactic, cybercriminals use malware to mine cryptocurrency on a victim's device without their knowledge or consent.
Well, it’s a matter of concern for us all as we might lose all our digital assets if we ever encounter such a dodge.
In this article, we will delve into the details of cryptojacking, including how it operates and the measures individuals can take to safeguard their devices from this type of malware.
What is Cryptojacking?
Cryptojacking is a type of cyber-attack in which malware is used to mine cryptocurrency on a victim's device. The malware is usually transported thru a malicious email attachment, a drive-by download, or a fake software update. Once the malware is installed on the victim's device, it begins to mine cryptocurrency using the device's processing power and electricity. The mined cryptocurrency is then directed to the attacker's wallet.
How does Cryptojacking Work?
Cryptojacking malware typically works by injecting code into the victim's device that uses the device's processing power to mine cryptocurrency. The malware may also use the device's electricity to power the mining process. The cryptocurrency that is extracted is transferred to the wallet of the attacker, where it can be swapped for other cryptocurrencies or traditional currency.
Cryptojacking malware can be supplied to a victim's device in a number of ways, including:
- The malware may be sent as an add-on in a seemingly harmless email. Upon opening the attachment, the malware infects the victim's device.
- The malware might be transported to a victim's system over a drive-by download. This occurs when the victim visits a website that has been compromised by the attacker, and the malware is automatically downloaded to the victim's device.
- The malware can be carried as a fake software update. The victim may believe they are updating a legitimate program when in fact; they are installing malware on their device.
How to Protect Yourself against Crypto Mining Malware?
Cryptojacking poses a significant risk to the safety of your device and private information. But you can safeguard yourself from this kind of malware by taking preventive measures.
Here are some things you should do:
- Keep your software and operating system up-to-date: Software updates often include security patches that can help protect your device from malware.
- Use anti-virus software: Anti-virus software can aid spot and remove malware from your device.
- Be cautious of email attachments and links: Don't open email add-ons or click on links from unknown sources.
- Be careful when visiting websites: Be careful when visiting websites, especially those that are not well-known.
- Use a VPN: A VPN (Virtual Private Network) can help protect your device from drive-by downloads.
- Use Ad-blocker: Ad-blockers can prevent ads from loading on your device, which can help prevent drive-by downloads.
- Monitor your device: Keep an eye on your device's performance and look out for any unusual activity. If you notice any unusual activity, take your device to a professional.
Cryptojacking is a malicious technique that poses a significant risk to the security of your device and personal information. To safeguard against this type of malware, it is crucial to take proactive measures such as using antivirus software, not downloading from unreliable sources and many other actions discussed above. By being proactive, you can effectively defend your device and personal information against the dangers of cryptojacking.
