About time a university started researching Bitcoin seriously.
Stress testing the network and protocol by a neutral party is something we should be grateful for, regardless of the immediate consequences.
If they can disrupt the network, so can others. And then I prefer this uni to do it, so we can learn from it rather than die from it.
Topic: Is Bitcoin currently under attack? - page 2. (Read 3938 times)
what is new is that they've actually demonstrated, with evidence, their theory in action.
Well, new back in May when their results were first shared.
This is for the race attack (on 0/unconfirmed transctions), and not a 51% attack which could reverse confirmed transactions.

They describe how they could connect to their "test vendor", which means that vendor's node wasn't configured according to the recommendations (i.e., no incoming connections, explicitly connect outgoing to hub nodes):

Can someone pls post a link to their paper; thanks
Zurich? Is it where a lot of bankers live? 
It is a university, so I figured they were not hostile.
Did not see any mention of contact with the devs.
Still, 10% of the network is a hell of a lot to just "turn on" suddenly
Wonder how much more they have up the sleeve.

this is actually old news from a few weeks back when they published the paper. at that time, they said they had contacted the devs.

if it were an attack why would they have contacted the devs ahead of time?
I just noticed this thread in the mining section:

Swiss Federal Institute of Technology Zurich (http://www.ethz.ch/) has started to mine with large power:
