Setting aside if this is true or not (and my gut feeling is that it is not), given the widespread impact of an AES or RSA crack what should one do with such knowledge? It seems irresponsible to just publish it and let the chips fall. On the other hand if you've spent your entire career in the field such a breakthrough would be the ultimate achievement and would expand your career opportunities a thousandfold and it would be very difficult to keep it to yourself or a handful of colleagues sworn to secrecy.
