Last week, Swedish television reported about a break-in at a water station in Järbo, located in Sweden.
The perpetrator might had contaminated the water – and the public was therefore told to collect water from tank trucks until laboratory evidence showed that the water was safe to use.
Two days later, the danger was over.
But what if the target was not the water, but the IT systems? One can prevent a regular door from locking by placing a newspaper in the doorway. Similarly, it is possible to prepare an IT system for future attacks. It is very common for computer networks to be exposed and in principle unprotected within a facility. Connecting a computer in the size of a matchstick for a few seconds is all that is needed. There is also no laboratory that can provide a test result that will show if you have been attacked or not.
