New, More-Powerful IoT Botnet Infects 3,500 Devices In 5 Days (arstechnica.com)

An anonymous reader quotes a report from Ars Technica: There's a new, more powerful Internet-of-things botnet in town, and it has managed to infect almost 3,500 devices in just five days, according to a recently published report. Linux/IRCTelnet, as the underlying malware has been named, borrows code from several existing malicious IoT applications. Most notably, it lifts entire sections of source code from Aidra, one of the earliest known IoT bot packages. Aidra was discovered infecting more than 30,000 embedded Linux devices in an audacious and ethically questionable research project that infected more than 420,000 Internet-connected devices in an attempt to measure the security of the global network. As reported by the anonymous researcher, Aidra forced infected devices to carry out a variety of distributed denial-of-service attacks but worked on a limited number of devices. Linux/IRCTelnet also borrows telnet-scanning logic from a newer IoT bot known as Bashlight. It further lifts a list of some 60 widely used username-password combinations built into Mirai, a different IoT bot app whose source code was recently published on the Internet. It goes on to add code for attacking sites that run the next-generation Internet protocol known as IPv6. The best-of-breed approach "is driving a high infection speed of Linux/IRCTelnet (new Aidra) so it can [infect] almost 3,500 bot clients within only five days from the moment its loader was first detected," a researcher who goes by the handle Unixfreakjp wrote in a blog post reporting on the new malware. "To incarnate a legendary botnet code into a new version that can [target] the recent vulnerable threat landscape is really inviting more bad news."

    Whoever decided putting devices without sufficient resources to defend themselves, or be updated, directly onto the Internet was a good idea should have his professional certifications revoked and forbidden to administer anything more complicated than his own home network. And that home should probably be denied connectivity to the world.

    The IoT is not necessarily a bad idea in concept, but it has been implemented exceptionally poorly, and those devices that cannot be updated need to be disconnected forever, or at least hidden on their own private networks. Vendors who cannot or will not patch their devices should be compelled to recall them, as violations of Part 15 rules against causing harmful interference.

      The home of the person who decided to sell non-upgradeable devices and let them connect directly to the Internet is the only one I'm saying should be removed from it. Part 15 rules have their analogous components in most countries that regulate the RF spectrum (which is practically all of them), I just used the reference I know.

      If you want to connect your multi-color LED Christmas lights to the Internet, then you should be required to administer such a setup just as much as you would any other computer you hook up. The same is true of your thermostat. If the vendor does not allow the devices to be adequately secured, then you have no business connecting them to anything more than your own local network, and if they manage to jump past firewalls and affect the world at large, you should get disconnected until you fix it, just like everyone else who is part of a botnet should be.

      Months? Try *years*. Ignoring the frivolous crap like fridges and kettles, the IoT has basically grown out of the previous generation of SCADA and Industrial Control & Automation (ICA) hardware, plus IP enabled versions of things like access control, building management systems, CCTV and so on. In almost every single case, even where you'd assume that the vendor ought to know better, the rush to get a product to market has trumped any security considerations and quite often the design can be summed up as "take an existing analogue product, put an Ethernet enabled chip on the side of it, slap an Ethernet jack on the case, give it an SKU, and update the product brochure".

      The really scary part is that that is still only scratching the surface of the problem. You also need to keep in mind that many of the original products that the IoT devices are based on are considered mature - they've been in development and on the market for well over a decade in many cases - yet researchers are still finding major security flaws in the underlying devices, e.g. the recent exploits of Siemens' SCADA systems. Factor in that in order to get the "big data" off these myriad devices and into "the cloud" to meet the necessary levels of buzzword compliance means that you are also negating any possibility of a physical air gap between the systems and the public Internet and it's been obvious for much longer than a few months that we've been heading for a major trainwreck (possibly quite literally since rail is also moving towards IoT systems).
