That could conceivably allow an attack on RSA, but AES?  A connection between factoring and AES would in and of itself be an huge (and totally unexpected, and vanishingly unlikely) deal.

What's in the linked report makes no sense.

It's not out of the question that someone has come up with a new approach to factoring, but if so we're talking major award material.  Not impossible, but highly unlikely.  Certainly not anything to worry about without more information - and absolutely unrelated to AES.
