Way too vague. It talks about the output of the AES block algorithm being definitively non-random for certain inputs but then talks about factoring integers which has nothing to do with symmetric transforms.

I'd (obviously) question their code, the implementations of their algorithms, etc. instead. Also, no university I know publishes results like this instead of in a respectable journal. If you really wanted to be fancy, you'd call a press conference, not some dodgy PR news service.
