There aren't any new findings here. It's merely a rehash of the Weak DH attack (by the same researchers) that was made public in May of this year: https://weakdh.org/
Still, it's a good reminder that you should not be using 1024-bit Diffie-Hellman.

Just to clarify (because I was confused when I read your comment), the weak DH attack was made public by the same people who wrote this post and the academic paper attached to it. It looks like the post and the paper are part of the same "release".
Conflict of interest disclaimer: I was a grad student of Professor Halderman's several years ago.
If I'm not mistaken, they gave a presentation in May and have now published a full technical paper.
Perhaps rehash is too harsh a word to apply to a paper that contains more details than given in the slides.
No criticism of the authors is intended (to the contrary, their findings are amazing and very important). But readers need to know this isn't a new attack before they go off panicking.
