Well said El Reg
There's no doubt that in many cases the Chinese government and the PLA get blamed for attacks which were unofficial or didn't really originate in China. It's also surely true that much of the hype in the West is generated by those hoping to profit from increased government and corporate cybersecurity budgets.
Facts are important and what the lack of knowledge seems to say is: we don't really have a clue who attacked us. And that is more, even the more worrying?
(a) blame those people over there (we don't have any disclosable facts so let's just blame 'em anyway?)
(b) we don't have the technology or agreements in place to say for sure who attacked what and when
(c) in times of economic woe if we shout loud enough and encourage enough white hate attacks maybe, just maybe a huge pot of government funded contracts might arrive in our business post?
The lack of facts or disclosable facts is worrying.
The lack of means to establish where attacks started from is worrying
Blaming nations without disclosing hard facts is worrying.
