I hope he releases this tool, cause I'd like to use it to find out as much details as possible about a bitcoin theft I was the victim of in June. I'd be surprised if it really works to be honest, but you never know.

There's an interesting paper published 22 July online at http://arxiv.org/abs/1107.4524 entitled An Analysis of Anonymity in the Bitcoin System. There's an article based on that paper here: http://anonymity-in-bitcoin.blogspot.com/2011/07/bitcoin-is-not-anonymous.html

It's not Blitcoin, of course. I'll be interested to see what Kaminsky has come up with.

You are WRONG!
he seems to be serious. but unmasking is maybe a far fetch.
but i will gladly read the sliders when they come out. Smiley

Consensus on the mailing list seems to be that this guy built a graph analysis tool, using some well known properties to associate addresses.

If that's the case it's kind of far-fetched to call it a security vulnerability. But until someone that was there reveals more, it's only guessing...



something that correlates transactions to nodes, like MagicalTux's proof of concept for mining clients?
displays everything on a google map?

He announced it at BlackHat yesterday - expect it to be a little while before even the slides show up, but more details will be forthcoming.

Or someone who actually went to Blackhat might post. I couldn't afford to go. Sad

From this article: http://searchsecurity.techtarget.com/news/2240039221/Black-Hat-2011-Dan-Kaminsky-reveals-network-security-research-topics

Quote
BitCoin, a digital, virtual currency system, was the platform for some of Kaminsky’s new research. BitCoin is a payment system that charges a low cost per transaction. Each transaction is digitally signed and broadcast, supposedly anonymously, over a peer-to-peer network. Kaminsky announced a new tool called BlitCoin that unmasks one or both ends of a BitCoin transaction.

Anybody know anything about this supposed tool to unmask bitcoin users? Google search for "blitcoin"+kaminsty just returns two links to the article quoted above:

That won't be true for long, but here is what I see:
