It seems pretty speculative to me that there's some large database with all of the mandated software backdoors and keys to get access to. And if it existed, I don't know that it would be such a large threat.
Certainly security bugs and professionals inside of industry are targeted by hackers already.
Given everything else, I don't know how large an issue this is (compared to say, hacking nuclear defense systems, energy grid, military C2C, etc).
It would be interesting to see whether this is considered a threat scenario by the USG.
