Secret NSA map reveals China’s successful hacks

China has infiltrated more than 600 companies and government agencies with cyberattacks within the past several years, according to a secret National Security Agency (NSA) map.

The map, obtained by NBC News, shows red dots indicating digital assaults on companies ranging from Google to Lockheed Martin, as well as a number of government and military agencies.

The stretch from Washington, D.C., up through New York City to Boston is especially cluttered with successful digital intrusions. California also has more than 50 dots scattered throughout, with many located around Silicon Valley.

The hackers reportedly made off with everything from hybrid car technology, to information on pharmaceutical products; to air travel records, to specifics about U.S. military systems.

The map was part of a February 2014 briefing from the NSA/CSS Threat Operations Center, meaning the attacks presented would stretch back to the beginning of 2009.

China is widely considered a main cyber adversary to the U.S.

The Asian power is believed to be responsible for the recent catastrophic hacks at the Office of Personnel Management (OPM). The incident compromised two sensitive databases at the agency, exposing more than 22 million people’s personal data.

In addition to broad corporate cyber espionage, Beijing officials are thought to be building a massive database on U.S. government workers. The information could be used to imitate officials, stage future cyberattacks, or even blackmail workers and recruit informants.

In May 2014, the Department of Justice indicted five members of the Chinese military for hacking the U.S. It’s the government’s only major public response to date to China’s ongoing cyber onslaught.
