A new hacking technique dubbed BREACH can extract login tokens, session ID numbers and other sensitive information from SSL/TLS encrypted web traffic, say researchers. Secret data crucial to securing online banking and shopping can be lifted from an HTTPS channel in as little as 30 seconds, we're told. BREACH (short for Browser …
Do you mean through botched key management or an actual breakthrough in number theory proving what is NP or NP complete?
So the question is Sky Digital with it's 2048 bits of RSA encryption likely to be broken anytime soon?
Somehow I kind of doubt it.
Re: "post cryptography?"
The fear of RSA brokenization has nothing to do with NP. You really just need fast factorization, which is not an NP-complete problem (it can be solved in polynomial time by the magically-well-guessing nondeterministic turing machines, so is in NP). You apparently need a quantum computer though (this being an exercise for the engineer), or a mystery polynomial-time algorithm that does factorization, if it exists (compare PRIMES is in P)
Now if you reduce NP-completeness or even NP-hardness to P, hell, you will be the master of the universe before sunset, and not in a metaphorical way either.

Don't have to go anywhere near that far before the gubernment wants to have a talk with you and work will suddenly go dark to the rest of the world.

Methinks, asdf, there be a number of problems which would really be many new leading opportunities for those and/or that in the field to resolve and share if they wish, and/or just exploit in the vast stealthy darkness of mass ignorance and arrogance for personal enrichment and absolutely fabulous reward, should one have cracked such as is spoken of here on this thread and would be also an enigmatic quantum [qubit*] conundrum and government intelligence service providers nightmare regarding the processing of information which be hoovered up covertly and clandestinely but which in Great IntelAIgent Games plays in reality and virtual reality be deliberately specifically provided for discovery to lead both prime and sub-prime operating systems in a completely novel and quite alien direction beyond any traditional conventional established command and control, with not the least of those problems and/or opportunities being that governments would be no where near intelligent enough to understand the dilemma which would be collapsing their systems remotely from virtual spaces afar, and thus would engagement with them through a knock at the door and a chat be quite unlikely, even if one would be leaving them a clear enough trail and tales to follow with direct communications with their more widely known by the public, security and secret intelligence services.
However, big money making businesses which work in the shadows and venture into the dark side may be a different kettle of fish to spear phish and have a cosy chat with.
And all of the above may or may not have been thoroughly tested and proven, not by theoretical experiment but through heretical experience, and that would make it exponentially considerably more valuable proprietary private intellectual property which be more suited and destined to remain in pirate and renegade domains and right dodgy royal regimes rather than entering the public education space.

And how is this any different from the BEAST exploit?
Attack on CBC is usually considered different from attack on deflate.
But if you are not interested in minutiae you can file it under "attack on the internets" along with DNS poisoning and a poor sod with excavator who severs cable from your house to your provider.
It's very different to BEAST, but I really can't see this as any substantial difference to CRIME, other than the code generating the multiple requests resides on the attacker's website (which the victim has to vist) as opposed to finding a cross-site-scripting vuln on the target website.
@AC and @djack - Thanks for clarification
what is he saying?
“There’s a small, but definite chance that RSA and non-ECC Diffie-Hellman will not be usable for security purposes within two to five years,” said Alex Stamos of Artemis Internet, a division of iSEC Partners. “We’re not saying this is definite," he added.
So which is it? Small but definite, but not definite? Sounds like a candidate for political office.
Re: what is he saying?
"It isn't definitely going to happen, but there is a definite chance that it will". Sounds a bit light on information to me, because I don't think anyone would claim there is a zero chance of it happening. If he'd quantified it, even very approximately, it would have been more useful.
Re: what is he saying?
The supersymmetry of cryptography!
"Maybe soon, possibly!"
Same shjt, different day. Anytime you can extract information (energy) from a cryptographic system, eventually you reach a point where brute force (also ever increasing in capabilities) will succeed. We can hem and haw about how we go about teasing out that internal energy state, but it always comes down to this. Put another way, if I can measure it, I can test it. If I can test it, I can break it.
Nothing new in times when and spaces where everything is possible and therefore most likely?

Re: Nothing new
Maybe we should all be a bit more concerned that the NSA hasn't been concerned about HTTPS for a while?
Read the BREACH white paper
The authors state that for this to work:
1: Be served from a server that uses HTTP-level compression
2: Reflect user-input in HTTP response bodies
3: Reflect a secret (such as a CSRF token) in HTTP response bodies
And, of course, the attacker needs to be "local" to the victim, will only work with short secret keys, and the attacker needs to send THOUSANDS of requests.
The web app has to be written STUPIDLY for this to work. "Oh, I'll echo ARBITRARY PLAINTEXT into my encrypted body for any request URI." Hello, nobody thought that this would be a problem??? If the data comes in through a URI, KEEP IT OUT OF THE ENCRYPTED STREAM! This is simply a classic plaintext attack, and that's all there is to it.
