Zero Day Attack Targets SCADA Systems

On June 17, 2010, researchers at VirusBlokAda, an anti-virus software company in Belarus, published a report (.pdf) on a trojan which was specifically designed to target process conrol server software (commonly referred to as SCADA software) used in critical infrastructure. Further work by Frank Boldewin uncovered a snippet of code (figure 2) which specifically calls the Siemens WinCC SCADA system (figure 1).
