The infrastructure systems of three US cities have been attacked, according to the Federal Bureau of Investigation.
At a recent cybersecurity conference, Michael Welch, deputy assistant director of the FBI’s cyber division, said hackers had accessed crucial water and power services.
The hackers could theoretically have dumped sewage into a lake or shut off the power to a shopping mall, he said.
Industrial control systems are becoming an increasing target for hackers.
