It turns out torrenting platforms are not the only ones toying with alternative methods to convert traffic to cash. A week after The Pirate Bay admitted to secretly running a cryptominer to borrow visitors’ CPU resources to bank on Monero coins, television giant CBS was caught doing the same with Showtime.

In fact, the popular broadcaster had purportedly implemented the mining solution on two official Showtime network websites – Showtime.com and Showtimeanytime.com – according to information security analyst Troy Mursch, who first documented the discovery acting on a tip from Twitter user SkensNet.

What is especially outrageous is that CBS had enabled the mining software on Showtime’s sites without any notification or request for consent to its subscribers. For more context, the miner was taking up to 60 percent of the overall visitors’ CPU capacity when Showtimeanytime.com was sitting idle in browsers.

Following coverage from The Register and Gizmodo, CBS appears to have removed the mining tech from the websites. Fortunately, Mursch was fast enough to save screenshots from Showtime’s website before, during and after running the miner.

As you can observe in the images above, the network opted to implement Coinhive – the same JavaScript-based solution The Pirate Bay relied on for the mining “tests” it ran on its own website.

The more troubling aspect of this move is that, as of recently, Coinhive has similarly been employed by a number of malware developers, seeking to hijack users’ computing resources to stack coins.

We have contacted CBS and Showtime for further comment and will update this piece accordingly should we hear back.
