College Network Attacked With Its Own Insecure IoT Devices (zdnet.com)

An anonymous reader writes:An attacker compromised over 5,000 IoT devices on a campus network -- including vending machines and light sensors -- and then used them to attack that same network. "In this instance, all of the DNS requests were attempting to look up seafood restaurants," reports ZDNet, though the attack was eventually blocked by cybersecurity professionals. Verizon's managing principal of investigative response blames the problem on devices configured using default credentials -- and says it's only gong to get worse. "There's going to be so many of these things used by people with very limited understanding of what they are... There's going to be endless amounts of technology out there that people are going to easily be able to get access to."
The article suggests "ensuring that IoT devices are on a completely different network to the rest of the IT estate." But it ends by warning that "until IoT manufacturers bother to properly secure their devices -- and the organizations which deploy them learn to properly manage them -- DDoS attacks by IoT botnets are going to remain a huge threat."

    This will defeat 'default password' attack botnets, provide just enough security to keep a device sort-of secure even under active incompetence, AND provide easy default password recovery given physical access to the device (which already negates software security to begin with.)

    A number of devices I've had over the years already do this. While many devices do not due to cheap quality control, anything that is getting put on a college campus should be at least a single step up from that, and device metadata can be input into the flash during quality assurance testing as part of the flashing/testing procedure.

      I had to install one of those nasty IoTs on Friday. Wave, formerly Astound, has now required an Encrypted Box to allow me to watch Basic Cable TV. And here I went, thinking that they were the Anti-Comcast.
      Last week, as Channels blinked out of existence, only to be replaced by a message that they were doing this for my own good, I came to realize that _everybody_ involved in the Cable Industry is a Goon. There are no Good Guys there. And no, I am not expecting "Better Internet Service", and I'm not buying the line that the Channels were being "Converted" to a Digital Format to make my Internet better. They already _were_ in a Digital Format- Clear QAM. Only now, it's encrypted. Even CSPAN is encrypted. (How can that possibly be legal?)
      There are real reasons why they do this, but try getting just one of those fuckers to admit it. The first is: they can cut off the signals remotely without "rolling a truck", for any reason that they like, which saves them money, and the savings will be passed to the Customers, right?
      The second reason is that every single one, without exceptions, of their Customers are Pirates and Thieves. Preventive measures are called for.
      But the third reason, the main reason, is that after the "Free" period, they can charge me monthly for it, for a rubbish box made in China, made for a buck, that talks about me to them, but also potentially anybody else interested. What hours do I watch TV. What Channels do I watch. And by the way, this mandated IoT is just as rubbish as all the other IoTs, which means it can be harvested.
      For those of a Technical Bent, it is a Cisco, going by the name of technicolor, (Did they pay for the Technicolor naming rights?), DTA 271HD.
      I want to knobble it.
      Why not me? Somebody else with less than honest intentions is going to do so anyway.
      It can't even be turned off. Oh, on the remote there is an off button, which silences the TV, but it consumes exactly the same amount of power, 4.3 Watts, as when it is "On". Watts that _I_ now pay for. (Yes, at current Rates, only about $10 a year, but it is the principle of the thing.)

      Oh, I needed a new Cable Modem as well, another "technicolor" box. But I knobbled my last one to see what outgoing connections it was making before; it shouldn't be too difficult with this one as well.

The owner of the individual device often (though perhaps not in this case?) still has a working device as far as they can tell, so it doesn't really affect them, either. The fix for the device is to buy a new one, so it's actually a net win for the manufacturer at this point.
