While the U.S. has been blocking Huawei from its market over fears about cyber security, the NSA has created a backdoor into the telecom-equipment company's products for spying purposes, the NYT reports, citing documents supplied by Edward Snowden.
One of the NSA's aims was to find links between Huawai and the People's Liberation Army (PLA), which the U.S. believes is the source of much hacking. However, the NSA has also been using its access to spy on targets in other countries.
The central question that the U.S. has is whether Huawei is independent, as the company maintains, or a front for the PLA, as American officials suggest. The documents don't provide an answer.
The revelations add to previous disclosures about NSA spying, which have already hurt Cisco and other U.S. companies, with IBM and Symantec also appearing to have been affected.
