SSL/TLS Vulnerability Details to be Released Friday
I'm getting a lot of emails asking about articles that ultimately reference this upcoming talk: "BEAST: Surprising crypto attack against HTTPS" (http://ekoparty.org/2011/juliano-rizzo.php)
I don't have any extra details. Anything that I write now will be unnecessary speculation. It sounds like it will be interesting; their presentation last year on Padded Oracle Attacks (the crypto Oracle, not the database) certainly was.
UPDATE: Dr J links us to "A CHALLENGING BUT FEASIBLE BLOCKWISE-ADAPTIVE
CHOSEN-PLAINTEXT ATTACK ON SSL" that may describe the attack. This attack requires that the attacker be able to sniff the traffic and run code on the victims machine to inject the chosen-plaintext into the stream.
My recommendation is still to wait until we see the details before formulating a response, but sight-unseen the following steps couldn't hurt:
- Users: Don't bank using someone else's wifi.
- Browser Authors: Update to support TLS 1.2
- Servers Admins: Configure to support TLS 1.2
