Cryptojacking

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.

Detection

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.

Impacts

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.
