Admiral Michael Rogers,who runs the NSA, told the committee that China and one or two other countries could attack power utilities, aviation and financial firms.
China and other countries have the ability to enter these kind of systems and to shut down the networks.
This isn’t the first time the USA has accused China of mounting cyber attacks, but it’s something that the Chinese government resolutely denies.
According to Reuters, a foreign ministry representative said that China absolutely banned cyber hacking and accused the USA of making cyber attacks on it and other nations.
The NSA still harvests phone records in the USA but earlier this week a bill to regulate surveillance failed and the agency will wait until a law is passed before making any major changes in its strategies and tactics.
