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 the events the attacks disabled the computers that were controlling heating in the buildings.
Both of the buildings where managed by Valtia. The company who is in charge of managing the buildings overall operation and maintenance. According to Valtia CEO, Simo Rounela, in both cases the systems that controlled the central heating and warm water circulation were temporarily disabled.
In the city of Lappeenranta, there were at least two buildings whose systems were knocked down by the network attack. In a DDoS attack the network is overloaded by traffic from multiple locations with the aim of causing the system to fail.
In an interview with Etelä-Saimaa, Rounela estimated 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.
To DDoS heating systems is just, plain cold.
