What really concerns me in this are these comment(s) by DHS:
The threat briefings followed an internal DHS intelligence report published in January that stated the risk of a cyber attack against U.S. electrical infrastructure was low.
“We assess the threat of a damaging or disruptive cyber attack against the U.S energy sector is low,” the report, labeled “for official use only,” says.
The report said advanced cyber attackers, such as nation states like Russia and China, are mainly seeking to conduct “cyber espionage.”
One of the reasons 9/11 was so successful was the "failure of imagination" that occurred among bureaucrats. So no one connects the dots when foreign nationals begin taking flight lessons, when pilots commit suicide with their planes (EgyptAir 990), etc etc.
I hope these comments are not more in that line of "see no evil hear no evil" that ends up costing us all.
