L.S.<br><br>Some bitcoin &quot;security vulnerabilities&quot; have been discussed by Dan Kaminsky at BH 2011, there is one article about this dated yesterday:<br><br><a href="http://searchsecurity.techtarget.com/news/2240039221/Black-Hat-2011-Dan-Kaminsky-reveals-network-security-research-topics">http://searchsecurity.techtarget.com/news/2240039221/Black-Hat-2011-Dan-Kaminsky-reveals-network-security-research-topics</a><br>
<br>The article is very unspecific though. They talk about a tool called &quot;blitcoin&quot; that &quot;unmasks&quot; both sides of a bitcoin transaction. A google search also turned up nothing, except some misspellings. <br>
<br>Does anyone have more information?<br><br>JS<br>
