CIA Director Leon Panetta Warns of Possible Cyber-Pearl Harbor

Top Intelligence-Security Officials Say Computer Attacks Increasing

By JASON RYAN

Top U.S. intelligence officials have raised concerns about the growing vulnerability the United States faces from cyberwarfare threats and malicious computer activity that CIA Director Leon Panetta said “represents the battleground for the future.”

“The potential for the next Pearl Harbor could very well be a cyber-attack,” he testified on Capitol Hill Thursday before the House Permanent Select Committee on Intelligence.

Director of National Intelligence James Clapper also appeared, telling the committee, “This threat is increasing in scope and scale, and its impact is difficult to overstate.”

There are roughly 60,000 new malicious computer programs identified each day, Clapper said, citing industry estimates.

“Some of these are what we define as advanced, persistent threats, which are Read more…

How Space Weather affects the US Power Grid

February 4, 2011 Comments off

The US power grid is a complex electrical apparatus that has well-known sensitivities to space weather disturbances. Recent changes in its design and utilization have significantly reduced its operating margins to supply us with on-demand electricity. This means there is less flexibility available with which to deal with power shortages and blackouts.

Space weather events can damage equipment over wide geographic regions so that recovery delays become substantially longer and more costly.

The 23rd Cycle – Chapter 4 – Describes in detail the state of the US power grid, and the forces which are driving it to be far more vulnerable to solar storms than at any time in the past.

“As North America has evolved into a unified power-sharing network of regions, each buying and selling a diminishing asset, US domestic power has become more vulnerable to Read more…

Mexico supplies electricity to wintry Texas

February 4, 2011 Comments off

MEXICO CITY (AFP) – Mexico’s state electricity company on Wednesday started supplying electricity to the US state of Texas, where demand shot up amid unusually cold temperatures and caused power outages.

Mexico’s Federal Electricity Commission “was determined to support Texas with electrical energy faced with the problems the state is suffering due to climatological conditions,” a statement said.

An energy transfer of 280 megawatts began at midday (1800 GMT) via the north Mexican border cities of Nuevo Laredo, Reynosa and Piedras Negras, it added.

Texas Governor Rick Perry said in a statement that power and emergency management experts were working with utility providers to ensure power was restored as quickly as possible.

“Until that happens, I urge businesses and residents to conserve electricity to minimize the impact of this event,” Perry added.

An epic winter storm Wednesday buried more than a third of the United States in drifting snow, sleet and ice that brought air and road travel to a halt.

Snowstorms also paralyzed air transport, blocked operations in factories and caused schools to shut in the Mexican city of Ciudad Juarez, across the border from El Paso, Texas.

Ciudad Juarez mayor Hector Murgia said the temperatures of around minus 13 degrees centigrade (8.6 Fahrenheit) were the lowest recorded in almost 50 years.

Nasa warns solar flares from ‘huge space storm’ will cause devastation

January 13, 2011 Comments off

Solar Maximum is happening now between 2011 and 2013 as part of Solar Cycle 24. My question is, why is this not being reported in the major newspapers and news outlets in the United States?

National power grids could overheat and air travel severely disrupted while electronic items, navigation devices and major satellites could stop working after the Sun reaches its maximum power in a few years.

Senior space agency scientists believe the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013, The Daily Telegraph can disclose.

In a new warning, Nasa said the super storm would hit like “a bolt of lightning” and could cause catastrophic consequences for the world’s health, emergency services and national security unless precautions are taken.

Scientists believe it could damage everything from emergency services’ systems, hospital equipment, banking systems and air traffic control devices, through to “everyday” items such as home computers, iPods and Sat Navs.

Due to humans’ heavy reliance on electronic devices, which are sensitive to magnetic energy, the storm could leave a multi-billion pound damage bill and “potentially devastating” problems for governments.

“We know it is coming but we don’t know how bad it is going to be,” Dr Richard Fisher, the director of Nasa’s Heliophysics division, said in an interview with The Daily Telegraph.

“It will disrupt communication devices such as satellites and car navigations, air travel, the banking system, our computers, everything that is electronic. It will cause major problems for Read more…
