This past weekend, Showtime websites were found to be running a
script that allows the sites to mine visitors’ extra CPU power for
cryptocurrency, as pointed out by users on Twitter. The afflicted
sites included showtime.com and showtimeanytime.com, but the
script has since been removed following reports from Gizmodo and
the site, it was made as an alternative to banner ads as a
way for website owners to get around pesky ad-blockers.
Ironically, some ad-blockers have now included Coinhive on the
list of the banned.
This is like going to a restaurant and finding out the valets were using your car as an Uber while you ate.
