    What is Cryptojacking?

    Cryptojacking is the unauthorized use of a person’s computer, tablet, or mobile phone to mine cryptocurrency. This can occur when a person visits a website that has been compromised with cryptojacking code, or when they unknowingly download a malicious file or app.

    How Does Cryptojacking Work?

    When a device is cryptojacked, its CPU is used to solve complex mathematical problems that are necessary to mine cryptocurrencies like Bitcoin and Monero. This process consumes a significant amount of the device’s processing power and can cause it to run slower than usual.

    Signs of Cryptojacking

    • Sluggish performance
    • Overheating
    • Increased electricity consumption
    • Unexplained spikes in CPU usage

    Protecting Yourself from Cryptojacking

    Use Ad Blockers and Anti-Malware Software

    To avoid cryptojacking, users can install ad blockers and anti-malware software that can block cryptojacking scripts and prevent them from running on their devices.

    Keep Software Updated

    Keeping software and operating systems updated ensures that any known vulnerabilities that could be exploited for cryptojacking are patched.

    Be Cautious of Downloads and Websites

    Be careful when downloading files or visiting websites, as these can be sources of cryptojacking code. Only download from reputable sources and use caution with unfamiliar websites.

    Deploy Network Security

    Network security measures such as firewalls and intrusion detection systems can help prevent unauthorized access to devices and networks, lowering the risk of cryptojacking.


    Understanding cryptojacking is the first step in protecting oneself from this growing threat. By staying informed and taking proactive measures, individuals and organizations can defend against cryptojacking and safeguard their devices and networks from unauthorized cryptocurrency mining.
