Smart-Grid Control Software Maker Hacked

tsu doh nimh writes "Telvent, a multinational company whose software and services are used to remotely administer and monitor large sections of the energy and gas industries, began warning customers last week that it is investigating a sophisticated hacker attack spanning its operations in the United States, Canada and Spain. Brian Krebs reports that the attacker(s) installed malicious software and stole project files related to one of Telvent's core offerings — OASyS SCADA — a product that helps energy firms mesh older IT assets with more advanced 'smart grid' technologies. A follow-up story from Wired.com got confirmation from Telvent, and includes speculation from experts that the 'project files' could be used to sabotage systems. 'Some project files contain the "recipe" for the operations of a customer, describing calculations and frequencies at which systems run or when they should be turned on or off. If you're going to do a sophisticated attack, you get the project file and study it and decide how you want to modify the pieces of the operation. Then you modify the project file and load it, and they're not running what they think they're running.'"

      SCADA systems are somewhat distinct from smart meters. SCADA does do HV switching.

      The 'smart meters' don't currently have access to the internet. The lines that would do that belong to the homeowners. It is unlikely that the homeowner has the legal right to let the power company borrow some bits, even if they are willing.

      Smart meters also shouldn't be controllable from the internet.

      No one is getting access to the scada system without going through private fibre or being onsite. About half of our smart meters have an ip address the rest are using gprs, but most of them don't control anything, and a couple don't do anything audio frequency load control wasn't already doing for a long time (the tech behind how they turn your hot water system on and off, which i think is the 'frequencies' the hacker has stolen in the story).

    I mean look at SCADA. The whole field seems to be staffed by idiots.
    They think that OPC (OLE for Process Control) is a good idea, they still use that, even though the networking component works via DCOM, and it's all Windows only.

    I mean a sane person would go and have sensors spit out text. That text can then be easily processed and archived easily. You can even batch process it, if you want.
    You can of course, also pour it into some SQL database if you prefer to, but having your primary data as text means that you can easily change your database engine without having to worry about compatibility.

    For OPC you need additional software just to be able to archive it.

    A simple (non-XML) format also would have the advantage of being easy to parse. You might, for example have a little single line header, having the number of the meter in it. Then you have each line representing a measurement point. First column could be the time in Unix epochs, then a space, then the measurement values. Such a format can easily be parsed, quicker than it can be read from RAM and without the danger of buffer overruns.

      Sensors that spit out text? Who in their right mind would want that?

      SCADA grabs sensor readings from the underlying control system, most likely running on some PLCs, where you have to do calculations on the data in order to feed back control values to the process being controlled.

      Now, a PLC is, admittedly, sort of like the general purpose CPU's dumb brother, and the instructions it accepts are rather limited. But, for a number of reasons, they're immensely suited for their task. The single most important one being the ability to safely and easily change a program that is in production. This feature is important because control systems often have to be tuned when they're commisioned, they don't just work out of the box. You have to fiddle with constants in order to get it working, perhaps even change the structure of the control algorithm.

      Because we control engineers have to fiddle with the program while it is running, we really don't want to do string to int/float/whatever conversion and the reverse when working on the PLCs. That would just be yet another place where we could scew up horribly, causing a country wide electrical blackout in the proces. It's hard enough as it is, so keep it simple, stupid!

      Ignorant IT people who think they know better than control engineers how to design & operate control systems. The rant about OPC was beautiful, in its own ignorant way, and completely exposes the GP as someone who's probably never seen a control system in his life, probably never will see one, and wouldn't have the first clue how to program, troubleshoot, or maintain it.

      There's historically been a certain amount of tension between control engineers and IT folks for that very reason; the smartest IT folks are the ones who ask the control engineers what they need to do their jobs, provide it, then stay the hell out of our way. The rest make our blood boil.

      Besides where is the problem building a PLC sending its output variables as text?
      Furthermore, in the example of the company mentioned in the article, the smart meters probably didn't have a PLC connected to them. They were probably small devices with a micro controller.

      Again, it's all fine and dandy if you connect your PLCs via a ProfiBus or whatever, but once it involves actual IT, you will have to play by the rules of good IT. (Of course there's a _lot_ of bad IT)

      Limit switches, solenoids, pushbuttons, motor contactors, relays, pilot lights, current transmitters, modulating control valves, even robotic motion controls -- good luck replacing all that gear with 'smart' versions that now have to understand text instead of simple electrical signals and not losing so much as a millisecond of response time.

      I probably ought to give you some benefit of the doubt in that you meant "the PLC's data that passes to/from the SCADA" but you used the word "output" and that has a meaning to control engineers, a meaning you apparently don't grasp since you are quite ignorant on this subject.
