Snowden deserves the Nobel Peace Prize and the Vatican should consider canonizing him.

To be canonized you have to have performed a miracle, but If he somehow get's pardoned by the DoJ or the Obama administration we could probably consider that requirement met.

Reading these slides, I'm trying to parse what these slides do or do not say. I'd like to leave aside the speculation about what the NSA is probably doing.

First of all, XKeyscore seems to be primarily about the frontend query interface rather than the backend data storage, at least as far as I can tell. It looks like you can basically query their database by email address and get a set of records (email, chat, http logs) back. It looks like there are separate tools for viewing specific records as well. I assume they're joining records on some combination of email address, IP address, timestamp, etc -- not unlike a modern ad server.

A few practical thoughts: * It's worth noting what's not shown in these slides. Specifically, I don't see any ability to query the full text of emails. The more I see about this, the more I'm convinced the NSA is not collecting email body texts directly from corporate servers. Facebook messages I'm less sure of. * How are they collecting HTTP data? I assume intercepting at network hubs? * Given that it appears that individual records are HTTP requests, I'm shocked at how few requests are in the database. 41 billion seems an order of magnitude smaller than I'd expect. Could it be a record is something else? * Interesting to note the "Miranda number" and "Foreign Factor" fields that look like ways of saying "yes, I have permission to do this." Might explain why a sysadmin could bypass these things but your everyday NSA analyst could not.

Holy shit... Apparently, the only way to ensure privacy is to go Stallman . Funny how yesterday's "conspiracy crackpot" became today's visionary.

How does browsing the web via e-mails and cron jobs make for more privacy?

No javascript tracking. Very strange behaviour (therefore, less behaviour tracking). That's what I can think of.

This bit both somewhat limits the impact and makes Greenwald et. al.'s claims that most everything is being Hoovered up a lot more credible: " The XKeyscore system is continuously collecting so much internet data that it can be stored only for short periods of time.

These slides are from 2008... I'm sure their capabilities have increased significantly.

From the slides http://www.theguardian.com/world/interactive/2013/jul/31/nsa... "Show me all the VPN startups in country X, and give me the data so I can decrypt and discover the users" Does this mean using VPN is not very safe from dragnet?

You probably don't need to break the encryption because eventually all traffic has to exit the VPN's company's endpoint, and at that point it can be captured. Meta data such as the browser's fingerprint can be used to tie traffic to an individual, for example, if you see them log in to a regular HTTP site with an email or a username, this information could probably be used to figure out who they are. Armed with this information, all other traffic originating from that endpoint (or elsewhere) with the same browser fingerprint.[-1] can be monitored. Weak keys can also cause the encrypted tunnel to be compromised. Also, PPTP is considered a very insecure tunneling protocol[0] but still used.

You could also break into the VPN company's servers and do interesting things too. There's also the possibility of timing attacks to determine the real IP address of the VPN user, although that's fairly a sophisticated method and quite difficult to do.

Bear in mind that this presentation dates back to 2008, which is a long time in tech years. Who knows what they're capable of now. All that's known is that they're not capable of less.

VPNs are useful for three things: protecting yourself against relatively unsophisticated bad guys sniffing traffic on a local network (for example, an unsecured wireless network), bypassing geographic content restrictions (e.g. using Pandora in Sweden), and circumventing ISP traffic shaping (often they'll not shape VPN traffic because it's used for businesses, and businesses can be whale customers).

Here's an interesting legal question: If a non-US resident or NSA target posts a thread on HN, and a US person replies to the thread, is the US person now open to unlimited data collection? Alternately, if you Facebook-like the same thing an NSA target has, are you then subject to unlimited data collection?

I don't know about forums, but I suspect that being Facebook friends with a non-US citizen is enough to subject a US citizen to unlimited collection.

This is overwhelming. Even when you always hear the claims about we knew this was going on, somehow it is still shocking when you see it all laid out infront of you with screenshots and the capabilities described. I can see how they get HTTP information, since they would intercept at transit hubs - but how are they getting all Facebook private messages and Gmail? I was also looking for another unique ID that users ar…

I think it would be very easy for the NSA to obtain the private keys to SSL of popular sites, eg Facebook, Gmail. Either through coercion or hacking.

Tempora in the UK stores all internet data for 3 days and metadata for 30 days too. Wouldn't surprise me if most western governments use XKeyscore along with data sharing agreements with each other.

One of the screen shots: http://static.guim.co.uk/sys-images/Guardian/Pix/audio/video... says: Top Secret Comm(?) REL() to USA, AUS, CAN, GBR, NZL confirming the previous suspicions that many other governments are on board. Der Spiegel actually has reported a few weeks back about XKeyscore [1] and that it is used by the BND (Germany's NSA). I.e. all this data is also available to the NSA equivalents of Australia, Can…

Bonus: The NSA likely can get around the "no spying on US citizens" by just requesting data from those governments, who proceed to pull it out of the NSA's web interface.

That UI looks awfully similar to a theme I've seen used in SharePoint Portal Server. I hope that's not what they use for the front end, but I wouldn't put it past them.

Having worked with SharePoint extensively for years, I'm highly confident this isn't the case. It's just plain-old crappy custom-coded HTML4 forms from what I can tell and similar colors, so one could easily think so. But at closer look, it definitely not any of the SP versions 2003, 2007, 2010 or 2013. Maybe 2001 but I highly doubt even that.
