Read Webmasters: Have some (sub resource) integrity! (InfoSec Guy)
Earlier today it was discovered that a large number of websites (over 4,000) – including UK government and NHS websites – had been compromised with a “cryptominer”. A cryptominer is a piece of software that “mines” cryptocoins like Bitcoin, LiteCoin, Ethereum, etc, which in turn generate income. When a cryptominer is included within the code of a website and a visitor visits a web page on the site, his/her web browser becomes a “miner” and their device’s CPU is used to “mine” coins for whoever placed the cryptominer within the code. Essentially, someone else profits at your expense (and at the detriment to your device, if its CPU is being maxed out through mining), and all this takes place without your knowledge!
