Some things that appear to be missing in that report are these:
(1) WTF are these multi-million dollar companies doing about computer security? If this "IP theft" really is so important why don't they have proper (ideally physical) separation of external (internet) and internal (valuable) networks? Too much cost/trouble?
(2) Most of the vulnerabilities being exploited are either people or, equally relevant, down to MS & Adobe in the majority of cases. Why is the US gov not penalising them for such a "IP rape" of the nation?
(3) Last time I looked, IP was covered by patents and trademarks which can be enforced against those who copy it (even if stupidly, e.g. Apple vs Samsung). Are we to really to believe such a huge value of IP is not protected by these established means?
(4) Considering most US corporations have out-sourced to China already (and the Chinese are smart enough to make most "joint ventures"), and they do so to save money so staff move a lot, is that not also a real risk for your IP? If so, why are they now complaining about the bloody obvious?
