Cryptojacking makes surfing the web similar to walking through a minefield: you never know when you might land on a booby-trapped site.
Stealthy cryptocurrency mining scripts have found their way to a variety of websites – streaming, gaming, online stores, and so on.
The craze started with CoinHive, but copycats have soon started popping up and increasing the probability for users to get their browsers hijacked into mining crypto currency (mostly Monero).
Mining scripts have been found added to popular browser extensions and mobile apps, and themes and plugins for popular content management systems (WordPress, Magento, Joomla and Drupal).
So what can you do to prevent your browsers/devices being hijacked to do the miners’ work?
Some mobile enterprise security solutions have also begun offering the option of blocking access to cryptojacking and other cryptocurrency sites.
For non-enterprise users: if you notice that your mobile device is suddenly heating up more than usual or your battery is draining more rapidly than before, remove the latest app or two that you’ve installed, as chances are that it was an app that secretly mines cryptocurrency.
Chrome developers have been debating whether the browser should block or flag CPU mining attempts since early September, but have yet to reach a consensus.
In the meantime, Opera developers have added cryptocurrency mining protection to the beta version of its next big release of the browser.
