The first of these results attacks a signature scheme called HAWK, while the second is an improved attack against reduced-round AES. The first is a new key recovery algorithm against the non-standard signature scheme HAWK. It simply extends a bunch of tools that were lying around and well-known, and gets a good result. In short: they are now capable of understanding existing cryptanalysis results, synthesizing them into real new attacks, and even extending them. Even if models are good at producing real results, they’re much better at producing results that look real but are misleading.
