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

About Cryptojacking

  • Cryptojacking is the unauthorized use of someone else's computing resources to mine cryptocurrency.
  • 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 program is installed when the user clicks on an unsafe link or visits an infected website — and unknowingly provides access to their Internet-connected device.



  • It 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.


The primary impact of cryptojacking is performance-related, though it can also increase the costs for the individuals and businesses affected because coin mining uses high levels of electricity and computing power.

Prevention tips

  • Continuously monitor the resources on your computer that is processing speed and 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.
