DDoS Attack Halts Heating in Finland Amidst Winter (metropolitan.fi) 138

A Distributed Denial of Service (DDoS) attack halted heating distribution at least in two properties in the city of Lappeenranta, located in Eastern Finland. In both of these events, the attacks disabled the computers that were controlling heating in the buildings. An anonymous reader writes: Both of the buildings were managed by Valtia, the company which is in charge of managing the buildings overall operation and maintenance. According to Valtia CEO, Simo Ruonela, in both cases the systems that controlled the central heating and warm water circulation were disabled. In the city of Lappeenranta, there were at least two buildings whose systems were knocked down by the network attack. According to Rounela, the attack in Eastern Finland lasted from late October to Thursday -- the 3rd of November. The systems that were attacked tried to respond to the attack by rebooting the main control circuit. This was repeated over and over so that heating was never working.

        Indeed. I lived in China for a few years, and there winter starts on Dec 1st and ends on Mar 1st. That makes more sense, since it syncs up with both the calendar and the weather. The first 21 days of Dec are shorter and usually colder than the first 21 days of March.

        Actually, neither problem is that hard to solve with appropriate hardware. You just have to rate limit the network interrupt by only re-enabling it if there is room in the Rx queue. Another answer is to use a dedicated I/O processor for networking and a main processor that polls it only when idle. You can get WiFi devices with such a dedicated CPU built in these days. If it gets a DDOS, the I/O processor gets overloaded and polls from the main CPU just time out and the device continues to operate normally i

    Sorry but if your heating system is 100% cloud based so that a DDOS attack or internet outage will stop heat control, then it was designed by the worlds biggest morons.

    Cloud based is great for toys, for anything important it's 100% shit.

    • They didn't DDOS the internet, they DDOSed the device controlling the heater itself. This also isn't cloud based and has nothing to do with the cloud and everything to do with remote control of infrastructure.

      • by sjames ( 1099 )

        In other words, the device was connected to the cloud so that it could be attacked. And since they apparently can't fix it by disconnecting the controller from the internet (they're talking about relocating tenants), it is cloud dependent. Cloud doesn't JUST mean a massive provider like Amazon.

        • Got it. The cool kids use the cloud, the rest of us are stuck using the internet.
          • by sjames ( 1099 )

            In the sense that Cloud is more a marketing term than a technical one, yes. It's basically just the hipster way to say internet. It often indicates some sort of dependence on a remote server somewhere, generally unwarranted.

            It's a reference to the cloud icon in old style data flow diagrams.

            • It reminds me of one of the earlier buzzwords, "database". In the tech journals, the word "database" had specific properties (though those were still being argued about, so yeah). Then the marketing folks and PHB's heard enough techs saying the word, and soon the trade journals were full of copy, describing pretty much any collection of files used by a program as "their database", whether it was related to a DBMS or not.

              And don't get me started on when programs became apps.
        • In other words, the device was connected to the cloud

          Yes because Slashdot has deranged to the point where a network connection is now suddenly a cloud, even the same remote management systems that have existed since the internet first came online.

          • by sjames ( 1099 )

            "The Cloud" is just marketing speak for being utterly dependent on a remote server on the internet. How did you miss that one? Marketers like calling it the cloud because it's so fluffy.

            OP's point stands, it was stupid as hell to make the thing so that a flood or any other loss of connectivity would cause it to fail at it's most important function. Which end of the connection is DDOSed is of little importance to determining the level of stupidity.

            • Except it's not Cloud dependent. Remote access does not mean something is cloud dependent. It means that some additional abilities are exposed by it and this is something which we have doing since the day you first singed up to Slashdot.

Shithouse security for a device that was remotely operated, nothing more. An attack on the device directly caused it to reboot over and over again. That's a denial of service. DDOS doesn't mean "cut off internet access", it just means "cut off access" the means are not relevant.
