New clues everyone!
A few days ago, I was notified that Ryan Brooks had published the second step of the new hack.net puzzle - seems to be another tough one. The first step was solved by a Bulgarian team. I think Ryan was right when he said that the first version of the puzzle was only warm-up.
On a related note, I was extremely pleased to see new clues in solving the enigmatic Kryptos puzzle, located on CIA headquarters. Yesterday, the CIA revamped their website and put up some nice new close-ups of the Kryptos monument. This is a very welcome addition, since until now the agency has been extremely camera-shy in this respect. The images are available on https://www.cia.gov/about-cia/virtual-tour/kryptos/index.html
