What is Cryptojacking?
Cryptojacking is a cyberattack where hackers secretly use a victim’s computing resources to mine cryptocurrencies without their consent. Unlike traditional crypto mining, which requires permission and investment in hardware, cryptojacking exploits unknowing users, often leading to performance degradation, overheating devices, and increased electricity costs.

How Does Cryptojacking Work?
Hackers deploy cryptojacking software in two primary ways:
-
Through Malware: Malicious software is installed on a victim’s device, allowing the hacker to mine crypto in the background.
-
Via Browser-Based Attacks: Also known as cryptojacking in browser, this method involves injecting JavaScript into a website so that any visitor unknowingly contributes to mining operations.
Signs of Cryptojacking
Detecting cryptojacking can be challenging, but there are some telltale signs:
- Sudden Slow Performance: Your computer or smartphone becomes unusually sluggish.
- Overheating Issues: Devices run hotter than usual and crash frequently.
- Increased CPU Usage: Your device’s CPU usage spikes even when idle.
- Unexpected Battery Drain: Laptops and mobile devices lose battery quickly due to excessive processing power being used.
Cryptojacking vs Crypto Mining
While crypto mining is a legitimate activity that requires significant investment in hardware, cryptojacking is an unauthorized and illegal means of exploiting other people’s devices to mine cryptocurrencies. Crypto mining is consent-based and follows ethical guidelines, whereas cryptojacking is performed covertly without user knowledge.
Examples of Cryptojacking Attacks
Cryptojacking attacks have targeted individuals, businesses, and even major organizations. Some of the common cryptojacking tools used by cybercriminals include Coinhive, Crypto-Loot, and PowerGhost. These tools exploit vulnerabilities in systems and web applications to embed cryptojacking malware.
How to Prevent Cryptojacking
There are several cryptojacking protection methods to help users secure their devices:
-
Using Anti-Malware Software: Install reliable security software to detect and remove cryptojacking malware.
-
Avoiding Suspicious Links and Emails: Phishing emails often contain cryptojacking software, so avoid clicking unknown links.
-
Updating Software Regularly: Ensure your operating system and browser are updated to patch vulnerabilities.
-
Using NoScript Extensions: Browser extensions like NoScript prevent malicious scripts from running.
-
Monitoring CPU Usage: Regularly check your device’s CPU usage for unexpected spikes.
Stopping Cryptojacking Attacks
If you suspect cryptojacking on your computer, follow these steps:
-
Close the Affected Browser Tabs: If cryptojacking is occurring via a browser, close all suspicious tabs.
-
Remove Malicious Extensions: Go through your browser extensions and uninstall any unknown ones.
-
Run a Security Scan: Use anti-malware tools to scan and remove any cryptojacking threats.
-
Restart Your Device: A reboot can sometimes halt ongoing attacks.
