In his workshop entitled "Building, Attacking And Defending SCADA Systems in the Age of Stuxnet" at the Black Hat conference, security expert Jonathan Pollet has warned that some programmable logic controllers (PLCs) used to control industrial facilities are accessible on the internet without any access protection. An article on CNET said that the expert managed to use Google to track down the unprotected control interface of a transformer that is used at an electricity substation in the UK.
