===Utilities and industrial equipment===
Computers control functions at many utilities, including coordination of [[telecommunications]], the [[power grid]], [[nuclear power plant]]s, and valve opening and closing in water and gas networks. The Internet is a potential attack vector for such machines if connected, but the [[Stuxnet]] worm demonstrated that even equipment controlled by computers not connected to the Internet can be vulnerable. In 2014, the [[Computer Emergency Readiness Team]], a division of the [[Department of Homeland Security]], investigated 79 hacking incidents at energy companies.<ref>{{cite web |last1=Pagliery |first1=Jose |title=Hackers attacked the U.S. energy grid 79 times this year |url=https://money.cnn.com/2014/11/18/technology/security/energy-grid-hack/ |website=CNN Money |publisher=Cable News Network |access-date=16 April 2015 |url-status=live |archive-url=https://web.archive.org/web/20150218070238/https://money.cnn.com/2014/11/18/technology/security/energy-grid-hack |archive-date=18 February 2015  |date=18 November 2014 }}</ref>
