  • UK cyber chief says directors are devolving responsibility for hacks {sic} [iophk: "a step towards banning Microsoft, yet the article closes with Microsoft talking points"]

  • Ransomware and the Internet of Things

    But it is a system that's going to fail in the "Internet of things": everyday devices like smart speakers, household appliances, toys, lighting systems, even cars, that are connected to the web. Many of the embedded networked systems in these devices that will pervade our lives don't have engineering teams on hand to write patches and may well last far longer than the companies that are supposed to keep the software safe from criminals. Some of them don't even have the ability to be patched.

    Fast forward five to 10 years, and the world is going to be filled with literally tens of billions of devices that hackers can attack. We're going to see ransomware against our cars. Our digital video recorders and web cameras will be taken over by botnets. The data that these devices collect about us will be stolen and used to commit fraud. And we're not going to be able to secure these devices.
