Not so much the specific attack, as the broad class of attacks. I think this new work is in that same broad class but I am not a mathematician.

The idea in Marc Stevens' anti-collision work is that some inputs are "disturbance vectors" which do unusual things to the SHA-1 internals, and we want to detect those and handle that case specially since there is almost no chance of that happening by accident. It has a list of such vectors found during his research.

This paper doesn't talk about "disturbance vectors" but it does discuss ideas like "Boomerangs" which I think ends up being similar - I just don't understand the mathematics enough to know whether that means "the same" or not.
