NSA hacked Huawei, totally penetrated its networks and systems, stole its sourcecode

hmmm Let me see if I got this right

The NSA pwned Huawei having total control over their network and communications
The NSA warns everyone that Huawei is spying on us

Sounds like the NSA found a way to spy on US citizens by controlling a foreign firm and using them as a proxy to spy on people in the US.

Pretty sneaky Sis.
