Snowden Documents Show How Well NSA Codebreakers Can Pry

Der Spiegel has published today an excellent summary of what some of Edward Snowden's revelations show about the difficulty (or, generally, ease) with which the NSA and collaborating intelligence services can track, decrypt, and correlate different means of online communication. An interesting slice: The NSA and its allies routinely intercept [HTTPS] connections -- by the millions. According to an NSA document, the agency intended to crack 10 million intercepted https connections a day by late 2012. The intelligence services are particularly interested in the moment when a user types his or her password. By the end of 2012, the system was supposed to be able to "detect the presence of at least 100 password based encryption applications" in each instance some 20,000 times a month. For its part, Britain's GCHQ collects information about encryption using the TLS and SSL protocols -- the protocols https connections are encrypted with -- in a database called "FLYING PIG." The British spies produce weekly "trends reports" to catalog which services use the most SSL connections and save details about those connections. Sites like Facebook, Twitter, Hotmail, Yahoo and Apple's iCloud service top the charts, and the number of catalogued SSL connections for one week is in the many billions -- for the top 40 sites alone. ... The NSA also has a program with which it claims it can sometimes decrypt the Secure Shell protocol (SSH). This is typically used by systems administrators to log into employees' computers remotely, largely for use in the infrastructure of businesses, core Internet routers and other similarly important systems. The NSA combines the data collected in this manner with other information to leverage access to important systems of interest.

  3. Hysteria by MightyMartian · · Score: 3, Insightful

    Before we all get too hysterical, from the article itself:

    The digitization of society in the past several decades has been accompanied by the broad deployment of cryptography, which is no longer the exclusive realm of secret agents. Whether a person is conducting online banking, Internet shopping or making a phone call, almost every Internet connection today is encrypted in some way. The entire realm of cloud computing -- that is of outsourcing computing tasks to data centers somewhere else, possibly even on the other side of the globe -- relies heavily on cryptographic security systems. Internet activists even hold crypto parties where they teach people who are interested in communicating securely and privately how to encrypt their data.

    In other words, the NSA, GCHQ and other intelligence services are probably only able to crack badly configured or unpatched and badly out of date systems. That doesn't stop them from using out of band vulnerabilities like hacking into someone's PC or forcing some online service to open up the decrypted data, but it seems likely that if you have a well-managed cert chain and your systems are kept up to date and patched, the odds of anyone, government or otherwise, busting into your encrypted data seems pretty low.

    My big fear out of all this isn't the unlikely hacking of mainstream encryption schemes, but rather that those that do use encryption may end up being targets of other methods; like malware, to get at their critical data.

      The article is merely listing tools. I expect that if we have a spy agency, they will use the tools available to spy. That is what a spy agency does. If you're outraged that a spy agency actually does spy, then you're probably addicted to outrage or something.

      The problem with the NSA isn't that they are spying, it isn't that they know how to decrypt SSL or mount a MITM attack; the problem with the NSA is they are spying on everybody. Limit the spying to only enemies of the US, and only the paranoid will be outraged.

      They have fake certificates from trusted authorities for some major sites, and use MITM attacks to serve up fake pages with them. We know that GCHQ loves doing the latter, so it's a question of working out which certificate authorities have been compromised and deleting them. We can also potentially defend against this by using more certificate pinning and warnings which certificates change unexpectedly, as well as distributed certificate checks (to make sure the one you get is the same one everyone else gets).

      I don't think so because not many people use trusted authorities with SSH. (In fact I've never heard of anyone doing that, but surely there are people who do). Most likely the NSA just sits there sniffing traffic that goes by, waiting until there's an SSH to a new box (which actually happens a lot, every time you reinstall or something), then begin sniffing. After that they have the password and everything, so the attack can expand.

    Remember who they share this info with.

    That is actually just the start. I'll be happy to give some more examples:

    1: A DA going on a fishing expedition. That data, plus parallel construction, plus civil asset forfeiture ensures that they will have a packed jail and prison system, ensuring the campaign donations from private prison corporations keep on coming. Remember: 48 states have signed an agreement with Corrections Corporations of America to keep their jails at 90% bed space or else face fines hourly.

It wouldn't take much for copyright law to be amended, forcing people to have to "prove" ownership of IP, just as businesses have to cough up proof when the BSA guy comes around, or else the BSA guy will be back with the constable and lawyers with a motion of discovery.

It wouldn't take much for a lawyer to go through, say Slashdot's postings, and file hundreds of thousands of lawsuits on anyone bashing Sony.

    3: Other country's laws. People don't realize it in the US that Thailand's lese majeste laws apply here? Well, they do, and an American can get shipped over there for breaking them, due to extradition treaties. Same with Turkey and the Kingdom of Saudi Arabia. In theory, someone handing out events for their pagan festival or church bulletins can be shipped over there to be executed, due to violating Islamic sharia laws. Privacy is important, since it isn't just domestic LEOs, but LEOs of foreign countries who can press charges and have US citizens answer for them. Right now, it tends not to be enforced, but the laws are on the books, and the pastor who was televised burning a Koran might find himself in Riyadh facing an imam and a crowd with rocks and a can of gasoline.

    4: Laws created by treaties. The gun nuts fear the UN gun ban treaty that went into in effect last Christmas Eve. It wasn't ratified in the US... but that can change, and even though it didn't affect gun sales inside the US... it had a clause saying that UN could act as an enforcement agency within the US, operating independently from other LEOs. Now, think about this a minute. A law enforcement group with the power to use deadly force and enforce laws that were never put on the books by domestic lawmakers, with no way to contest their decisions. It might be something 3 percenters talk about now on talk radio... but do people remember how close ACTA came to being passed? It wouldn't be surprising to see another law like this come on the books under "anti-hacking statues" that would allow the UN to detain "hackers" under their own law, and under their own opinion.

    5: Ex wifes/husbands. An acquaintance of mine lives in California, had a bad marriage, with the wife divorcing him for someone richer. Well, she had a good attorney (courtesy her new BF), and got a pretty insane alimony settlement. Well, the husband was out of work at the time, couldn't pay the payments... so the judge tossed him in for nonpayment for six months. He got out after that, two years later, was back in (as in California, unemployment isn't a good enough reason to not pay alimony costs.) Well, this shit went on for about two years, until this guy, once he got released, booked it to Mexico. Now, the ex wife is offering a bounty for anyone to find him and bring him to "justice". Not that she needs the money, but just out of pure malice. Without privacy, people who just had a bad relationship with a sadistic other can be killed.
