    How does a browser injected coin miner work?


    I seem to have fell prey to a website that had either intentionally or unintentionally been injected with a coin miner. I first noticed high CPU temps and thought my CPU cooler had failed. Then I found Chrome's high CPU utilization in Task Manager and then the culprit website through Chrome's own task manager.

    Is this a form of malware? Does it infect the machine permanently? Or is it's focus to gain your system resources rather than personal information? Access to one's PC in any form is not good in my book. None of my AV mitigation's detected the miner.

    Are there any mitigation's that can be put in place to protect ourselves from such breaches? I'm surprised that Chrome does not have a lock on this behavior yet. Appreciate any assistance

    Hi.
    Have a read here:

    Explains it pretty well. You need some miner blockers in your browsers, at minimum.

    Thanks @simrick

    I notice that we have a coin mining thread here on Ten Forums in the Antivirus section as well: Protecting yourself from In-Browser Miners Solved - Windows 10 Forums

    Apparently if I had Malwarebyte's premium it would have detected the coin miner. It's the first time I've been aware of falling victim to one so will have to bolster security further!
