Warnings from U.S. Defense Secretary Leon Panetta and U.S. Department of  Homeland Security Secretary Janet Napolitano that enemy nations are carrying out  cyber attacks on the U.S. are on the rise.
The target? The U.S. electric  infrastructure.
Even President Obama has pointed out that “our enemies  are also seeking the abilities to sabotage our power grid, our financial  institutions and our air traffic control systems.”
But that may not be  the worst of it. Those same adversaries – China, Russia, Iran and North Korea –  also incorporate in their military doctrine the use of a nuclear electromagnetic  pulse, or EMP, attack as "part of a strategic operation that would basically  'throw the kitchen sink' at the United States," according to Cynthia E. Ayers,  who once was with the National Security Agency and currently is with the U.S.  Army War College.
These countries, she said, will "hit us with everything  – computer viruses, sabotage of critical communications nodes, kinetic strikes  on key information systems and a nuclear EMP attack."
"The last, an EMP,  is their best chance to collapse our national power grid and take us down,  perhaps permanently," she said.
In recent months, U.S. banks, the Federal  Reserve, oil and gas production companies, media outlets and U.S. Defense  Department and National Nuclear Security Administration entities have reported  what Ayers calls a "massive" number – "in the millions" – of cyber attacks  daily
As a former employee of the National Security Agency, she is very  familiar with cyber attacks on computers through the Internet and  telecommunications systems.
North Korea, for example, recently exploded a  nuclear weapon in what experts believe may have been a test of the  miniaturization of a nuclear bomb that could fit on its missiles. The Hermit  State recently tested successfully a three-stage missile that experts said could  reach the Western part of the U.S.
The North Koreans also orbited a  package during that missile test, which in the future could be a nuclear weapon  that could be exploded at a high altitude above the U.S., causing an EMP blast  that would virtually knock out the entire U.S. national electric grid  system.
Experts agree that countries that cannot match the U.S.  militarily have undertaken asymmetrical, or unconventional, warfare in an effort  to defeat or seriously impair America.
Such an attack would be in the  form of a kinetic engagement, much as Russia undertook when it invaded the  neighboring Republic of Georgia with a combination of cyber and military assault  techniques.
Ayers said that such an approach served as a "prototype" for  "the ultimate cyberwar."
"In fact, Russian, Iranian, Chinese and North  Korean cyberwarfare doctrine includes EMP attacks on critical infrastructure to  effectively remove both cyber capabilities and communications from the  battlespace of the adversary," Ayers said.
"Unfortunately, the  battlespace is increasingly civilian."
Just to be clear, she said, there  have been increasing warnings of a cyber and EMP threat from America's  adversaries to collapse the nation's critical infrastructure.
"“It is worth repeating," said U.S. Rep. Patrick Meehan, R-Pa. "The collapse  of critical infrastructure, whether through intentional attack or from the  effects of a great geomagnetic storm, would essentially remove the United States  as an actor on the world stage instantaneously, and long-term."
However,  Ayers pointed out, recent events such as a Cyber Security Conference last  October, would have been a good forum to underscore the threats, but there  apparently were "legal threats to the briefers" despite having been pre-cleared  to discuss nuclear power plant vulnerabilities.
“Their warnings were  ultimately withheld, not because the presenters were wrong, or even because of  classification, but because of private industry fears of the consequences of  such revelations made public,” Ayers asserted.
His assertion is  reinforced by a Chicago Tribune story last October revealing that legal fears  were muffling warnings of cyber security threats. A separate article in the  Sophos publication similarly referred to how nuclear power plant cyber security  warnings were silenced due to legal threats.
The notion of a "digital  warhead" now is coming into vogue, with the introduction apparently by the U.S.  and Israel of the Stuxnet virus aimed at industrial controllers associated with  Iran’s power grid and its suspected nuclear weapons-related  activities.
Ayers said the Stuxnet worm ultimately gave Iranian cyber  experts a "leg up" on the possibilities for response.
She said that the  Iranians could refocus this digital warhead and turn it into a weapon of mass  destruction.
In turning the Stuxnet virus on the U.S., Ayers said the  Iranians or any potential adversary could take down the U.S. power grid from  remote locations by targeting specific automated control systems for  destruction.
Such an initiative, she said, would be "only one step away  from a high-altitude nuclear (EMP) attack."
She pointed out that Iran and  other countries openly have discussed such a prospect with U.S.  officials.
"Even if the scale of such a threat seems too grandiose, the  fact that the U.S. has not to date responded kinetically to a major cyber attack  may make escalation in the form of incrementally more devastating cyber efforts  enticing alternatives to a smaller challenger with fewer resources," Ayers  said.
Yet, President Obama has ordered new waves of cyber attacks against  Iran even though the Stuxnet virus has become public knowledge.
For some,  Ayers says, this alone could become a justification for an Iranian response  "unless cyberwarfare is considered simply another tactic of a larger, more  strategic warfare doctrine – that is, combining kinetic, strategic communication  and cyber."
