This was actually all disclosed to the FBI in advance when the Mirai source code was originally released. Afaik Krebs has also been communicating with them and sharing his findings. It's not really a disclosure so much as a reaction because I'd assume the FBI investigation has advanced and he now believes it's the appropriate timing since all the puzzle pieces came together. The information has been held back for quite a bit to not interfere with the FBI.
