A Senate investigation released Wednesday [17 Sep] found that hackers linked to the Chinese government broke into US military transportation companies’ computer networks 20 times in a year.

But the Senate Armed Services Committee says officials of the US Transportation Command, responsible for moving troops across the globe in times of crisis, were told about just two of those incidents. If a system was compromised, they may not have known, the panel said.

[Emphasis added.] How is it possible that military transporters were not told that systems on which their functions depended had been compromised? Who made the decision to withhold these critical data? Why is that person/those people not being called to account? Why are those contractors who sat on these data still under contract?
