Motherboard writes about dodgy, javascript-using web sites which are throwing a little extra CPU load onto visitors and hoping they won't notice much.
Netlab 360's analysis suggests that in-browser cryptocurrency mining, which stormed back onto the world stage in 2017 after being dormant for several years (likely due to low cryptocurrency prices) via a torrent site is now chiefly the purview of porn sites. It's worth noting, too, that criminals have found some pretty creative ways to get people to mine cryptocurrency for them outside of website visits, including hacking an Argentine internet provider.
In-browser cryptocurrency mining has the potential to eat up your computer's resources and slow down your machine, making the trend of particular interest to cyber security researchers lately. Last year, Symantec predicted that in-browser mining would turn into an "arms race" in 2018 as malicious actors come up with even more inventive (and invasive) methods of mining digital coins with someone else's machine.

Feels like a tragedy of the commons scenario, though. If a million browsers each spent one penny worth of electricity so that the hosting site could mine $10 worth of coin (remember, javascript on a general-purpose CPU has *terrible* hashrate/efficiency), that's a net loss of $9990 that just gets pissed away as a side effect...

I suppose it depends whether it's during the winter. When your house is cold, suddenly previously inefficient uses of electricity become useful. Granted that it would be better off spending those cycles calculating something more useful for the planet though. Has anyone ever tried to make a cryptocurrency out of useful calculations like protein folding or SETI? I can see that it might be undesirable if you're effectively monetizing information that should be freely available scientific knowledge, a bit like patenting a genome.

I'd see that as an opportunity actually.
Imagine if pornhub started to do this instead of ads, now imagine if they also would sign agreements with the power-companies to curtail their mining when requested, it would be one very fast and very well distributed load-shedding. And if the geo-ip or similar is accurate enough they probably also could help reduce the risk of overload on specific parts of the grid during peaks.
It probably would be cheaper than having to run coal/gas/oil plants at partial burn all the time so they can ramp up to cover for intermittent sources (and for nuclear it would also be great since it means they always could go full power)
(I'm actually amazed that no nuclear operator hasn't set up a cryptocurrency miner on their premises (so it never hits the grid), and just run that at full blast when the price they get for electricity drops down below what they would get for the mining - or at least during negative prices [or when prices are below what it would cost to produce that kWh]).
