Last month the New York Times announced that Chinese hackers had stolen every employee’s corporate password, and not to be outdone, the Wall Street Journal and Bloomberg News then revealed that they’d been targeted as well (though hackers failed to infiltrate Bloomberg News). … According to a new national intelligence estimate, Chinese hackers have been rifling through the computer systems of a variety of American businesses as part of a massive operation that might be costing the country tens of billions of dollars. While it appears the hackers were targeting the media companies to keep tabs on their reporting on China, the National Intelligence Estimate found that the larger aim of the larger cyber-espionage campaign is to steal trade secrets and other data that could give China an economic edge.
