Abstract
We use computer-controlled industrial plants every day, even when we are not aware of that. We are using computer-controlled systems when entering the elevator, when staying in the airconditioned space and crossing the road or riding through a tunnel. Computer-controlled systems operate with complex production facilities such as a glass factory, a brewery plant or a nuclear power plant. In all these cases, the process is controlled
and monitored by computers or SCADA systems. This paper describes and analyzes the attack against the computer-driven industrial system. Several years ago general opinion that PLC systems were not vulnerable to malware was acceptable because PLC was not connected to the Internet and therefore, they were protected against malware. By the discovery of the Stuxnet malware the world was faced with a completely new way of using malware. For the first time malware was used as offensive weapons and the door for cyberwar was open wide. The paper presents the ways of infecting the computer and the area where the infection was most widespread.
