    In Context 

    • Cryptojacking’ attacks on computer systems have gone up by 30% to 66.7 million in the first half of 2022 compared to the first half of last year.

    What is Cryptojacking ?

    • It is a cyber attack wherein a computing device is hijacked and controlled by the attacker, and its resources are used to illicitly mine cryptocurrency.
    •  In most cases, the malicious programme is installed when the user clicks on an unsafe link, or visits an infected website — and unknowingly provides access to their Internet-connected device.
    • Detection 
      • Cryptojacking is hard to detect and the victims of these attacks mostly remain unaware that their systems have been compromised. 
      • Some telltale signs are the device slowing down, heating up, or the battery getting drained faster than usual.
    • Impacts 
      • The primary impact of cryptojacking is performance-related, though it can also increase costs for the individuals and businesses affected because coin mining uses high levels of electricity and computing power.
    • Prevention tips
      • Continuously monitor resources on your computer (processing speed, power usage)
      • Use browser extensions that are designed to block coin mining
      • Use more privacy-focused ad blockers
      • Install the latest software updates and patches for your operating system and all applications —especially those concerning web browsers
