Thousands of websites around the world have been found infected with a specific client-side script that forces visitors' computers to mine cryptocurrency for attackers without the users consent.
Users who visited the hacked websites immediately had their computers' processing power hijacked, also known as cryptojacking, to mine cryptocurrency without their knowledge, potentially generating profits for the unknown hacker or group of hackers.
It turns out that hackers now hijack websites, and injected their cryptocurrency-mining script into the server code.
The script that was inserted into the compromised websites often belongs to CoinHive—a browser-based Monero mining service that offers website administrators to earn revenue by utilizing CPU resources of visitors.
The mining software was found in more than 4,200 websites on the web.
