Both business and home computers hooked to the Internet have long been susceptible to hackers and viruses. Cell phones can even suffer this vulnerability. But the electrical grid, water and sewage systems?
An article
in The Wall Street Journal reports, "Cyberspies have
penetrated the U.S. electrical grid and left behind software programs
that could be used to disrupt the system, according to current and
former national-security officials." This apparently has been going on
for some time without a lot of press.
What is really interesting is that the companies themselves
did not discover the intrusions but were detected by U.S. intelligence
agencies. The spies are from China, Russia and other countries but it
is not clear whether or not they are government sponsored.
This could open up new questions in regard to embracing the smart grid concept. It would make you wonder who really is in control of your heating thermostat! We are happy to have our own miniature power plant meeting our energy demands without the intrusion of a faceless company (or worst, some hacker in another country) telling us we can have heat or lights but not both. Small and simple can make for a good nights rest.
