Cryptojacking is a relatively new threat in the world of cybersecurity threats that hides in the shadows and causes harm. This discreet and frequently undetectable type of cybercrime has been causing a surge in incidents, setting its sights on individuals and businesses. Its primary objective is secretly mining cryptocurrencies such as Bitcoin, Ethereum, and Monero.
In contrast to conventional cyberattacks that aim to acquire confidential data or extort payments, cryptojacking acts covertly in the background, evading detection until its harmful consequences become evident.
What is Cryptojacking?
The term "cryptojacking" is derived from the combination of the words "cryptocurrency" and "hijacking." It is a covert cybercrime where malicious actors use other people's computing devices, such as computers, smartphones, tablets, or even servers, to mine cryptocurrencies like Bitcoin and Monero without their knowledge or permission. Cryptocurrency refers to digital or virtual currency forms that use cryptographic techniques to secure transactions, regulate the creation of new tokens or coins, and verify the transfer of assets.
How does Cryptojacking Work?
Cryptojacking operates by stealthily installing cryptojacking malware on a target's device through malicious websites or advertisements, infected files, malware distribution, and infected emails or attachments. Once installed, the malware exploits the device's CPU/GPU processing power without consent. After that, it secretly engages in cryptocurrency mining, solving complex math puzzles to earn rewards. It drains computing resources without the user's consent, causing slowed performance, increased electricity costs, and potential hardware damage. Although it does not promptly compromise data privacy, it presents financial and operational risks, emphasizing the necessity for implementing detection and preventative measures in our increasingly interconnected digital realm.
How to Detect Cryptojacking?
Here are some
cryptojacking detection tips:
- Monitor CPU/GPU Usage:
Monitor your device's CPU/GPU performance. A sudden and sustained spike
may indicate cryptojacking
- Review Task Manager:
Check your task manager for unusual or resource-intensive processes or
applications
- Check for Cooling Fan Noise:
Increased mining can lead to louder fan noise
- Ad Blockers:
Consider using ad blockers with crypto-mining protection features
- Browser Extensions:
Regularly inspect browser extensions for unauthorized mining scripts
- Security Software:
Use antivirus and anti-malware tools that detect cryptojacking threats
- Network Traffic:
Monitor for unusual network traffic patterns
- Browser Warnings: Some browsers may issue alerts if cryptojacking scripts are detected
