Quick update on Google Chrome's Math.random() predictability by Amit Klein, Trusteer
This is a quick update regarding Google Chrome's Math.random implementation and its vulnerability. Our original results with Google Chrome 3.0 and above don't hold as-is for Google 6.0 and above due to a change introduced in the Google Chrome Math.random implementation. However, the attack algorithm can be modified to take this change into account, so the vulnerability is still in effect. As reported earlier, it is possible to read application states across domains, thus enabling for e.g. in-session phishing. This was reported to Google's security team earlier this year, which responded by stating that there is no ETA for a fix and we're free to publish our results.
