Hackers from a foreign location shut down a water pump of an undisclosed utility in Illinois last week, according a report by a cybersecurity expert.

The hacker attack was reported by Joe Weiss, an international authority on cybersecurity in his blog on Thursday and could be the first known remote attack on a U.S. industrial system.

"The IP address of the attacker was traced back to Russia," Weiss wrote.

Weiss said the disclosure was made by the Illinois Statewide Terrorism and Intelligence Center after SCADA software used to control industrial systems was hacked and customer usernames and passwords were stolen.But it took 2 to 3 months before it was identified as a cyber attack, according to Weiss.

The SCADA system was powered on and off, burning out a water pump, according to the report.

The U.S. Department of Homeland Security and the Federal Bureau of Investigation are investigating the case, DHS spokesman Peter Boogaard said, according to Reuters.
