A Surge of Sites and Apps Are Exhausting Your CPU To Mine Cryptocurrency (arstechnica.com)
Dan Goodin, writing for ArsTechnica: The Internet is awash with covert crypto currency miners that bog down computers and even smartphones with computationally intensive math problems called by hacked or ethically questionable sites. The latest examples came on Monday with the revelation from antivirus provider Trend Micro that at least two Android apps with as many as 50,000 downloads from Google Play were recently caught putting crypto miners inside a hidden browser window. The miners caused phones running the apps to run JavaScript hosted on Coinhive.com, a site that harnesses the CPUs of millions of PCs to mine the Monero crypto currency. In turn, Coinhive gives participating sites a tiny cut of the relatively small proceeds. Google has since removed the apps, which were known as Recitiamo Santo Rosario Free and SafetyNet Wireless App. Last week, researchers from security firm Sucuri warned that at least 500 websites running the WordPress content management system alone had been hacked to run the Coinhive mining scripts. Sucuri said other Web platforms -- including Magento, Joomla, and Drupal -- are also being hacked in large numbers to run the Coinhive programming interface.
Slashdot keeps mentioning this. Are you considering adding this to the website? That would be cool!
If people still knew how to write HTML, almost no web site would need to use any "JavaScript" or other "active content"
How would, say, a web-based front-end to an IRC server work without script? It needs to know when messages have arrived in order to display them. The same is true of a multi-user whiteboard, which needs to know when another user has drawn a stroke. In addition, server-side image map doesn't support drag input, only click input.
Or should those instead be native executables that a user can download, install, and use? If so, then because native executables are generally specific to one operating system, Murphy's law holds that such an application will inevitably be designed for an operating system other than the one your device regularly runs. And it's still "software [manually] downloaded from arbitrary foreign sources".
Or should real-time interactive applications instead be written for the Java Virtual Machine or the .NET Common Language Runtime? Even though one such executable can run on multiple desktop operating systems, it still generally excludes iOS and Android, and it's stlil "software [manually] downloaded from arbitrary foreign sources".
