With headlines like “New cyber threat compromises financial information – Experts say new threat could affect millions of sites”, you would think that the trust model of the internet is finally crumbled.
Following an hour long Friday evening wait for the demo, the Ekoparty demo for the SSL hack was staged. And it was interesting that the attack succeeded in cracking the SSL confidentiality model as implemented by the Mozilla Firefox browser when communicating with paypal.com web servers over https. At the same time, it seemed to be an impractical exploit targeting a weakness that was fixed three months ago in Chromium source code.
Also of note, is the fact that the attack has been well known for almost 10 years, it’s just that there hasn’t been a practical exploit implementing the attack. And that they refined their blockwise attack model far better than previous chosen-plaintext attack models, making it more effective than prior attacks.

UPDATE(9/26): Microsoft advises that they are investigating the matter for their Internet Explorer browser customers, stating that the issue is low risk anyways, “Considering the attack scenario, this vulnerability is not considered high risk to customers”. Perhaps they were one of the browser vendors that were not contacted about the vulnerability.
