Whether you’ve been cryptojacked locally on your system, or through the browser, it can be difficult to manually detect the intrusion after the fact. Likewise, finding the origin of the high CPU usage can be difficult. Processes might be hiding themselves or masking as something legitimate in order to hinder you from stopping the abuse. As a bonus to the cryptojackers, when your computer is running at maximum capacity, it will run ultra slow, and therefore be harder to troubleshoot. As with all other malware precautions, it’s much better to install security before you become a victim.
One obvious option is to block JavaScript in the browser that you use to surf the web. Although that interrupts the drive-by cryptojacking, this could likewise block you from using functions that you like and need. There are also specialized programs, such as “No Coin” and “MinerBlock,” which block mining activities in popular browsers. Both have extensions for Chrome, Firefox, and Opera. Opera’s latest versions even have NoCoin built in.
