Cryptocurrency has become increasingly popular during the past year or so. These decentralized virtual coins cannot be regulated by governments or other financial authorities.
Owing to their increased popularity, several website owners are using their visitor’s CPU and resources to mine cryptocurrency.
This practice isn’t new, however, this is the first time COMSATS university’s website has been spotted loading crypto-mining scripts.
COMSATS and Crypto-mining
If you visit the website without enabling an adblocker, you will notice a sudden spike in your CPU usage to 100%.
To check if this is true, just disable your adblocker or any other blocking extension, open your task manager (ctrl+alt+delete/ctrl+shift+Esc on Windows 7/10) and click on the performance tab.
If your CPU usage increases suddenly, this means a mining script is being run on your browser by the website.
Here is what we are talking about. There are no other tabs or applications being run in the background. Only comsats website is running on the browser, you can clearly see the CPU usage of the computer has hit 100%.
We are not sure whether COMSATS’ website administration knows about this or not. However, using the visitors’ computer CPU power without their consent to mine coins for your own benefit is not acceptable.
