Noticed your machine getting slow after visiting certain websites? They could be running cryptocurrency miners in your browser.
And of course, with the old pop-under trick <https://arstechnica.com/information-technology/2017/11/sneakier-more-persistent-drive-by-cryptomining-comes-to-a-browser-near-you/>, you may not even notice that there is a window still open and running the miner after you thought you’d closed the window to that site ... I don’t think this trick would work for me. I am rather fond of Compiz and its OpenGL-based animation effects. One of the effects I have turned on is windows moving temporarily to the side as other windows come to the front. This animation makes pop-unders rather noticeable ...
