Last week, hackers interfered with two multi-storey heating system in a denial of service attack. However, cases have been significantly increased, and only a part is detected.

Lappeenranta attack suffer a system Fidelix installations. Fidelix equipment did not attack the target substance but rather a middleman, through which sought to drive traffic to the actual attack, as is typical botnet.

Real estate Computers jammed on restart a cycle, which is why the processes behind them have been stopped: This led to the interruption of the heating.

Fidelix Director General Antti Koskinen know that these cases are not the only of its kind.

“One can speak of dozens of cases,” Koskinen starts. “Some of the cases is not understood why the equipment capricious. In others, the attack is over before it has a direct harm, because behind the systems, the processes have not had time to suffer, when parents the threshold is not exceeded. ”

“However, in Finland there are hundreds of potential targets which attacks like this can be done.”

“Building Services is networked with good reason, because it facilitates the maintenance of real estate, for example, makes it possible to react quickly to unexpected problems. Unfortunately, the security and the perception of its importance drag behind, “Koskinen says.

“The problem is that the connection should be safe VPN’s using, but because it is one of the more complex maintenance process, it is often chosen a more direct route and is left deliberately ignored it the security side. It is not considered so important, and now it’s chosen easy road hits back”

“The situation is, however, clearly improving. The real estate sector measures have been taken several years ago, and currently is sold only secure connections, unless the customer one reason or another do not want to specifically otherwise.”

Finnish Communications Regulatory Authority has created guidance on how real estate security should be built from the start.
