Siemens Patches Stuxnet-Like SCADA Bugs
German industrial control system manufacturer Siemens announced Monday that it had patched holes in some of its products that appear to resemble holes used by the popular Stuxnet worm in 2010.If left unpatched, vulnerabilities in the company’s Simatic STEP 7 and Simatic PCS 7 software could have allowed the loading of malicious Microsoft Dynamic-link Library files. This in turn could lead to an attack against systems that use STEP 7.
