Word seems to be filtering out that so called 'secure hashing algorithms' are all broken, and China has joined the U.S. in the very short list of countries with the ability.

How did they do it?

Only thing known for sure is that it has to do with the fact that the complexity of patterns an algorithm produces  progresses slower than the complexity of the algorithm. So in relation to hashing algorithms that means that you can take a large number of products of the algorithm e.g. public addresses, and find the pattern fairly easily, then backtrack to the private keys.

Anybody have more info?
