The draft, which has yet to be officially approved, found that malicious computer activity tied to China continues to persist following reports of attacks against Google and other U.S. companies.
The excerpts said Chinese telecommunications firms have disrupted or impacted U.S. Internet traffic.
Last March, web traffic from popular sites such as YouTube, Facebook and Twitter was temporarily affected by China’s own internal censorship system. User in Chile and the U.S. were diverted to incorrect servers or encountered error messages.
A similar incident happened in April where a large number of routing paths to various Internet Protocol addresses were redirected through networks in China.
This diversion of data would have given the operators of the servers on those networks the ability to read, delete or edit email and other information sent along those paths.
An official confirmed that the data diverted to China came from Fortune 500 companies and many branches of the U.S. government.
However, the report indicated that 2010 could be the first year over the past decade that shows a smaller number of logged threats
The report also cited the Defense Department's assertion that its own defensive measures over the past year have prevented a larger number of threats.
