Latest Snowden revelation – NSA and GCHQ have full access to German telecom systems

Filed under: Britain, Europe, Germany, Technology, USA — Tags: , , , , — Nicholas @ 12:21

In The Register, Kelly Fiveash sums up the latest information from Edward Snowden:

An NSA and GCHQ surveillance programme — dubbed Treasure Map — grants US and British spooks access to the networks of German telcos such as Deutsche Telekom, according to a new stash of leaked documents from Edward Snowden.

Der Spiegel published the latest revelations today. However, Deutsche Telekom reportedly said it had found no evidence of such tampering on its system.

“We are looking into every indication of possible manipulations but have not yet found any hint of that in our investigations so far,” a spokesman at the company told Reuters.

He added: “We’re working closely with IT specialists and have also contacted German security authorities. It would be completely unacceptable if a foreign intelligence agency were to gain access to our network.”

The Register sought comment from the telco, but it hadn’t immediately got back to us at time of writing.

The Treasure Map programme was described by Snowden as “a 300,000 foot view of the internet” in a New York Times story published in November last year.

New ways to bug a room

Filed under: Technology — Tags: , , , — Nicholas @ 08:33

MIT, Adobe and Microsoft have developed a technique that allows conversations to be reconstructed based on the almost invisible vibrations of surfaces in the same room:

Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag photographed from 15 feet away through soundproof glass.

In other experiments, they extracted useful audio signals from videos of aluminum foil, the surface of a glass of water, and even the leaves of a potted plant. The researchers will present their findings in a paper at this year’s Siggraph, the premier computer graphics conference.

“When sound hits an object, it causes the object to vibrate,” says Abe Davis, a graduate student in electrical engineering and computer science at MIT and first author on the new paper. “The motion of this vibration creates a very subtle visual signal that’s usually invisible to the naked eye. People didn’t realize that this information was there.”

[…]

Reconstructing audio from video requires that the frequency of the video samples — the number of frames of video captured per second — be higher than the frequency of the audio signal. In some of their experiments, the researchers used a high-speed camera that captured 2,000 to 6,000 frames per second. That’s much faster than the 60 frames per second possible with some smartphones, but well below the frame rates of the best commercial high-speed cameras, which can top 100,000 frames per second.

I was aware that you could “bug” a room by monitoring the vibrations of a non-soundproofed window, at least under certain circumstances, but this is rather more subtle. I wonder how long this development has been known to the guys at the NSA…

The sheer difficulty of obtaining a warrant

Filed under: Government, Law, Liberty, Technology, USA — Tags: , , , — Nicholas @ 08:21

Tim Cushing wonders why we don’t seem to sympathize with the plight of poor, overworked law enforcement officials who find the crushing burden of getting a warrant for accessing your cell phone data to be too hard:

You’d think approved warrants must be like albino unicorns for all the arguing the government does to avoid having to run one by a judge. It continually acts as though there aren’t statistics out there that show obtaining a warrant is about as difficult as obeying the laws of thermodynamics. Wiretap warrants have been approved 99.969% of the time over the last decade. And that’s for something far more intrusive than cell site location data.

But still, the government continues to argue that location data, while possibly intrusive, is simply Just Another Business Record — records it is entitled to have thanks to the Third Party Doctrine. Any legal decision that suggests even the slightest expectation of privacy might have arisen over the past several years as the public’s relationship with cell phones has shifted from “luxury item/business tool” to “even grandma has a smartphone” is greeted with reams of paper from the government, all of it metaphorically pounding on the table and shouting “BUSINESS RECORDS!”

When that fails, it pushes for the lower bar of the Stored Communications Act [PDF] to be applied to its request, dropping it from “probable cause” to “specific and articulable facts.” The Stored Communications Act is the lowest bar, seeing as it allows government agencies and law enforcement to access electronic communications older than 180 days without a warrant. It’s interesting that the government would invoke this to defend the warrantless access to location metadata, seeing as the term “communications” is part of the law’s title. This would seem to imply what’s being sought is actual content — something that normally requires a higher bar to obtain.

Update: Ken White at Popehat says warrants are not particularly strong devices to protect your liberty and lists a few distressing cases where warrants have been issued recently.

We’re faced all the time with the ridiculous warrants judges will sign if they’re asked. Judges will sign a warrant to give a teenager an injection to induce an erection so that the police can photograph it to fight sexting. Judges will, based on flimsy evidence, sign a warrant allowing doctors to medicate and anally penetrate a man because he might have a small amount of drugs concealed in his rectum. Judges will sign a warrant to dig up a yard based on a tip from a psychic. Judges will kowtow to an oversensitive politician by signing a warrant to search the home of the author of a patently satirical Twitter account. Judges will give police a warrant to search your home based on a criminal libel statute if your satirical newspaper offended a delicate professor. And you’d better believe judges will oblige cops by giving them a search warrant when someone makes satirical cartoons about them.

I’m not saying that warrants are completely useless. Warrants create a written record of the government’s asserted basis for an action, limiting cops’ ability to make up post-hoc justifications. Occasionally some prosecutors turn down weak warrant applications. The mere process of seeking a warrant may regulate law enforcement behavior soomewhat.

Rather, I’m saying that requiring the government to get a warrant isn’t the victory you might hope. The numbers — and the experience of criminal justice practitioners — suggests that judges in the United States provide only marginal oversight over what is requested of them. Calling it a rubber stamp is unfair; sometimes actual rubber stamps run out of ink. The problem is deeper than court decisions that excuse the government from seeking warrants because of the War on Drugs or OMG 9/11 or the like. The problem is one of the culture of the criminal justice system and the judiciary, a culture steeped in the notion that “law and order” and “tough on crime” are principled legal positions rather than political ones. The problem is that even if we’d like to see the warrant requirement as interposing neutral judges between our rights and law enforcement, there’s no indication that the judges see it that way.

Even if you’re “doing nothing wrong”, the NSA is probably tracking you already

Filed under: Government, Liberty, Media, Technology, USA — Tags: , , , — Nicholas @ 09:17

The argument that you’ve got nothing to worry about because you’re not doing anything wrong has long since passed its best-before date. As Nick Gillespie points out, you don’t need to be a member of Al Qaeda, a black-hat hacker, or a registered Republican to be of interest to the NSA’s information gathering team:

If You’re Reading Reason.com, The NSA is Probably Already Following You

Two things to contemplate on early Sunday morning, before church or political talk shows get underway:

Remember all those times we were told that the government, especially the National Security Agency (NSA), only tracks folks who either guilty of something or involved in suspicious-seeming activity? Well, we’re going to have amend that a bit. Using documents from Edward Snowden, the Washington Post‘s Barton Gellman, Julie Tate, and Ashkan Soltani report

    Ordinary Internet users, American and non-American alike, far outnumber legally targeted foreigners in the communications intercepted by the National Security Agency from U.S. digital networks, according to a four-month investigation by The Washington Post.

    Nine of 10 account holders found in a large cache of intercepted conversations, which former NSA contractor Edward Snowden provided in full to The Post, were not the intended surveillance targets but were caught in a net the agency had cast for somebody else.

    Many of them were Americans. Nearly half of the surveillance files, a strikingly high proportion, contained names, e-mail addresses or other details that the NSA marked as belonging to U.S. citizens or residents. NSA analysts masked, or “minimized,” more than 65,000 such references to protect Americans’ privacy, but The Post found nearly 900 additional e-mail addresses, unmasked in the files, that could be strongly linked to U.S. citizens or U.S.residents.

The cache of documents in question date from 2009 through 2012 and comprise 160,000 documents collected up the PRISM and Upstream, which collect data from different sources. “Most of the people caught up in those programs are not the targets and would not lawfully qualify as such,” write Gellman, Julie Tate, and Ashkan Soltani, who also underscore that NSA surveillance has produced some very meaningful and good intelligence. The real question is whether the government can do that in a way that doesn’t result in massive dragnet programs that create far more problems ultimately than they solve (remember the Church Committee?).

Read the whole thing. And before anyone raises the old “if you’re innocent, you’ve got nothing to hide shtick,” read Scott Shackford’s “3 Reasons the ‘Nothing to Hide’ Crowd Should be worried about Government Surveillance.”

Living in a post-Snowden world, under the gaze of the Five Eyes

Filed under: Australia, Cancon, Government, Technology, USA — Tags: , , , , — Nicholas @ 07:12

It’s been a year since the name Edward Snowden became known to the world, and it’s been a bumpy ride since then, as we found out that the tinfoil-hat-wearing anti-government conspiracy theorists were, if anything, under-estimating the actual level of organized, secret government surveillance. At The Register, Duncan Campbell takes us inside the “FIVE-EYED VAMPIRE SQUID of the internet”, the five-way intelligence-sharing partnership of US/UK/Canada/Australia/New Zealand:

One year after The Guardian opened up the trove of top secret American and British documents leaked by former National Security Agency (NSA) sysadmin Edward J Snowden, the world of data security and personal information safety has been turned on its head.

Everything about the safety of the internet as a common communication medium has been shown to be broken. As with the banking disasters of 2008, the crisis and damage created — not by Snowden and his helpers, but by the unregulated and unrestrained conduct the leaked documents have exposed — will last for years if not decades.

Compounding the problem is the covert network of subornment and control that agencies and collaborators working with the NSA are now revealed to have created in communications and computer security organisations and companies around the globe.

The NSA’s explicit objective is to weaken the security of the entire physical fabric of the net. One of its declared goals is to “shape the worldwide commercial cryptography market to make it more tractable to advanced cryptanalytic capabilities being developed by the NSA”, according to top secret documents provided by Snowden.

Profiling the global machinations of merchant bank Goldman Sachs in Rolling Stone in 2009, journalist Matt Taibbi famously characterized them as operating “everywhere … a great vampire squid wrapped around the face of humanity, relentlessly jamming its blood funnel into anything that smells like money”.

The NSA, with its English-speaking “Five Eyes” partners (the relevant agencies of the UK, USA, Australia, New Zealand and Canada) and a hitherto unknown secret network of corporate and government partners, has been revealed to be a similar creature. The Snowden documents chart communications funnels, taps, probes, “collection systems” and malware “implants” everywhere, jammed into data networks and tapped into cables or onto satellites.

It’s fair for the government to track social media activity

Filed under: Cancon, Government, Media — Tags: , , , , — Nicholas @ 09:36

In what might sound like a break with his long-established credentials on surveillance and privacy issues, Michael Geist says it’s fine for the government to track social media:

For most of the past decade, many people concerned with digital rights have used the Internet and social media to raise awareness in the hope that the government might pay closer attention to their views. The Canadian experience has provided more than its fair share of success stories from copyright reform to usage based billing to the Vic Toews lawful access bill. Yet in recent weeks, there has been mounting criticism about the government’s tracking of social media. This post provides a partial defence of the government, arguing that it should be tracking social media activity provided it does so for policy-making purposes.

[…]

With those caveats, I find myself supportive of the government tracking social media activity, if for the purposes of staying current with public opinion on policy, government bills or other political issues. Facebook and Twitter are excellent sources of discussion on policy issues and government policy makers should be tracking what is said much like they monitor mainstream media reports. Too often government creates its own consultation forum that attracts little attention, while the public actively discusses the issue on social media sites. It seems to me that the public benefits when the government pays attention to this discussion. Users that tweet “at” a minister or use a searchable hashtag are surely hoping that someone pays attention to their comment. To see that government officials are tracking these tweets is a good thing, representing a win for individuals that speak out on public policy.

There certainly needs to be policies that ensure that the information is used appropriately and in compliance with the law, but if the current controversy leads to warnings against any tracking of social media, I fear that would represent a huge loss for many groups that have fought to have the government to pay more attention to their concerns.

Michael Geist – Who’s Watching Whom?

Filed under: Business, Cancon, Government, Law, Liberty — Tags: , , , , — Nicholas @ 10:08

Published on 22 May 2014

One of the most talked about technology tradeoffs today is the question of how much privacy we give up to live in a world of convenience, speed and intelligence. We’re now less anonymous than many people are aware of or comfortable with, and headline-grabbing stories like the Heartbleed Bug don’t provide much reassurance for those of us seeking comfort around data privacy. How can we balance our need for anonymity with the incredible benefits of our connected world? World class Internet privacy expert Dr. Michael Geist helps us understand which current surveillance and privacy issues should be on your mind.

Dr. Michael Geist is a law professor at the University of Ottawa where he holds the Canada Research Chair in Internet and E-commerce Law. He has obtained a Bachelor of Laws (LL.B.) degree from Osgoode Hall Law School in Toronto, Master of Laws (LL.M.) degrees from Cambridge University in the UK and Columbia Law School in New York, and a Doctorate in Law (J.S.D.) from Columbia Law School. Dr. Geist is an internationally syndicated columnist on technology law issues with his regular column appearing in the Toronto Star and the Ottawa Citizen. Dr. Geist is the editor of From “Radical Extremism” to “Balanced Copyright”: Canadian Copyright and the Digital Agenda (2010) and In the Public Interest: The Future of Canadian Copyright Law (2005), both published by Irwin Law, the editor of several monthly technology law publications, and the author of a popular blog on Internet and intellectual property law issues.

Dr. Geist serves on many boards, including the CANARIE Board of Directors, the Canadian Legal Information Institute Board of Directors, the Privacy Commissioner of Canada’s Expert Advisory Board, the Electronic Frontier Foundation Advisory Board, and on the Information Program Sub-Board of the Open Society Institute. He has received numerous awards for his work including the Kroeger Award for Policy Leadership and the Public Knowledge IP3 Award in 2010, the Les Fowlie Award for Intellectual Freedom from the Ontario Library Association in 2009, the Electronic Frontier Foundation’s Pioneer Award in 2008, Canarie’s IWAY Public Leadership Award for his contribution to the development of the Internet in Canada and he was named one of Canada’s Top 40 Under 40 in 2003. In 2010, Managing Intellectual Property named him on the 50 most influential people on intellectual property in the world.

The technological democratization of law enforcement and the rise of “Little Brother”

Filed under: Liberty, Technology, USA — Tags: , , , , — Nicholas @ 09:44

If you care about your privacy, you’re equally worried about the intrusive surveillance state and the unconstrained snooping of corporations. You may now need to worry about your snoopy neighbours also getting in on the act, as Declan McCullagh explains on Google+. This is a response to someone on a private mailing list for Silicon Valley folks, who said that he had no issue with automated collection of license plate data:

Tomorrow one of your PV [Portola Valley] neighbors will set up a computer-connected camera on private property and aimed at the street. It records all those “plates exposed” going by and, by doing optical character recognition with free software such as ANPR MX (C# code, BSD-licensed), it records every time a car goes by. The DMV will happily provide drivers’ names based on the license plate*; there’s even a process for “bulk quantities” of data.** That information doesn’t include a home address, but that’s easy to come by through other searches.

Then the neighbor launches PVPeopleTracker.com. It updates in real time showing whenever someone is at home, and marks their house in bright red if they’re gone on an extended trip. If there are odd patterns of movement compared to a baseline — perhaps suspicious late-night outings — those can be flagged as well. Any visitor to PVPeopleTracker.com can sign up for handy free email alerts reporting at what time their targeted house becomes vacant each weekday morning. Other network-linked cameras in PV can supplement the PVPeopleTracker.com database, so that everyone driving in town will have their movements monitored, archived, and publicly visible at all times.

With more than one network-linked camera separated by a known distance by roads with known speed limits, it would be simple to calculate speeding violations and send automated alerts, with MP4 videos attached as evidence, to the sheriff and CHP. PVPeopleTracker.com can also be cross-referenced against databases showing, say, marijuana convictions; if your movement profile matches a known drug trafficker, law enforcement can be alerted. (Sorry about those false positives!)

“Mammals don’t respond well to surveillance. We consider it a threat. It makes us paranoid, and aggressive and vengeful”

Filed under: Cancon, Government, Liberty — Tags: , , , — Nicholas @ 08:58

Angelique Carson reports on a recent IAPP Canada Privacy Symposium presentation:

If marine biologist-turned-best-selling author Peter Watts is an expert on anything, it’s mammals. Speaking to 400 or so privacy pros and regulators gathered last week at the IAPP Canada Privacy Symposium to talk privacy and data protection, he used that experience to send a rather jarring — and anything but conventional — message:

Mammals don’t respond well to surveillance. We consider it a threat. It makes us paranoid, and aggressive and vengeful. But we’ll never win against the giant corporations and governments that watch us, Watts argued, so all we can develop is a surefire defense.

Think “scorched earth.” If we can’t protect the data, Watts posited, maybe we should burn it to the ground.

Hear him out: Mammals will always respond to the surveillance threat as they would any threat — with aggression, in the same way the natural selection process has shaped every other life form on this planet.

“Anybody who thinks their own behavior isn’t at least partly informed by those legacy circuits has not been paying attention,” he said.

Watts pointed to author David Brin’s assertion during his keynote recently at the IAPP’s Global Privacy Summit that while our instinct is to pass a law aimed at telling governments and corporations to “stop looking” at us, we should instead turn our gaze to them in the name of reciprocity.

“It’s not telling them do not look,” Brin said during his speech. “It’s looking back.”

But Edward Snowden is currently living in Russia after he tried to “look back.” And as someone who’s worked a lot in the past with mammals, Watts knows that, biologically, looking back is a bad idea: “To get into a staring contest with a large, aggressive, territorial mammal primed to think of eye contact as a threat display … I can’t recommend it.”

“Natural selection favors the paranoid,” Watts said.

“Parallel construction” and Godwinizing the NSA

Filed under: Government, History, USA, WW2 — Tags: , , , — Nicholas @ 09:33

At Popehat, Clark uses an excerpt from a Bruce Schneier post to make a larger point. Here’s what Bruce wrote last year:

This dynamic was vitally important during World War II. During the war, the British were able to break the German Enigma encryption machine and eavesdrop on German military communications. But while the Allies knew a lot, they would only act on information they learned when there was another plausible way they could have learned it. They even occasionally manufactured plausible explanations. It was just too risky to tip the Germans off that their encryption machines’ code had been broken.

And this is Clark’s take:

We know that the NSA collects all sorts of information on American citizens. We know that the FBI and the CIA have full access to this information. We know that the DEA also has full access to that data. And we know that when the DEA busts someone using information gleaned by the electronic panopticon of our internal spy organization, they take pains to hide the source of the information via the subterfuge of parallel construction.

The insight is this: our government is now dealing with the citizenry the same way that the British dealt with the Nazis: treating them as an external existential threat, spying on them, and taking pains to obfuscate the source of the information that they use to target their attacks.

Yeah, Godwin’s law, whatever, whatever. My point is NOT that the NSA is the same as the Nazi party (in fact, my argument has the NSA on the opposite side). My point is that the government now treats ordinary civilians as worthy of the same sort of tactics that they once used against the Nazis.

The NSA’s self-described mission – “Collect it all. Know it all. Exploit it all.”

Filed under: Government, Liberty, Media, Technology — Tags: , , , , — Nicholas @ 07:31

In The Atlantic, Conor Friedersdorf reviews Glenn Greenwald’s new book, No Place to Hide:

NSA - New Collection Posture

Collect it all. Know it all. Exploit it all.

That totalitarian approach came straight from the top. Outgoing NSA chief Keith Alexander began using “collect it all” in Iraq at the height of the counterinsurgency. Eventually, he aimed similar tools at hundreds of millions of innocent people living in liberal democracies at peace, not war zones under occupation.

The strongest passages in No Place to Hide convey the awesome spying powers amassed by the U.S. government and its surveillance partners; the clear and present danger they pose to privacy; and the ideology of the national-security state. The NSA really is intent on subverting every method a human could use to communicate without the state being able to monitor the conversation.

U.S. officials regard the unprecedented concentration of power that would entail to be less dangerous than the alternative. They can’t conceive of serious abuses perpetrated by the federal government, though recent U.S. history offers many examples.

[…]

But it is a mistake (albeit a common one) to survey the NSA-surveillance controversy and to conclude that Greenwald represents the radical position. His writing can be acerbic, mordant, biting, trenchant, scathing, scornful, and caustic. He is stubbornly uncompromising in his principles, as dramatized by how close he came to quitting The Guardian when it wasn’t moving as fast as he wanted to publish the first story sourced to Edward Snowden. Unlike many famous journalists, he is not deferential to U.S. leaders.

Yet tone and zeal should never be mistaken for radicalism on the core question before us: What should America’s approach to state surveillance be? “Defenders of suspicionless mass surveillance often insist … that some spying is always necessary. But this is a straw man … nobody disagrees with that,” Greenwald explains. “The alternative to mass surveillance is not the complete elimination of surveillance. It is, instead, targeted surveillance, aimed only at those for whom there is substantial evidence to believe they are engaged in real wrongdoing.”

That’s as traditionally American as the Fourth Amendment.

Targeted surveillance “is consistent with American constitutional values and basic precepts of Western justice,” Greenwald continues. Notice that the authority he most often cites to justify his position is the Constitution. That’s not the mark of a radical. In fact, so many aspects of Greenwald’s book and the positions that he takes on surveillance are deeply, unmistakably conservative.

The NSA worked very hard to set themselves up for the Snowden leaks

Filed under: Government, Liberty, Technology — Tags: , , , , , — Nicholas @ 10:30

A few days back, Charles Stross pointed out one of the most ironic points of interest in the NSA scandal … they did it to themselves, over the course of several years effort:

I don’t need to tell you about the global surveillance disclosures of 2013 to the present — it’s no exaggeration to call them the biggest secret intelligence leak in history, a monumental gaffe (from the perspective of the espionage-industrial complex) and a security officer’s worst nightmare.

But it occurs to me that it’s worth pointing out that the NSA set themselves up for it by preventing the early internet specifications from including transport layer encryption.

At every step in the development of the public internet the NSA systematically lobbied for weaker security, to enhance their own information-gathering capabilities. The trouble is, the success of the internet protocols created a networking monoculture that the NSA themselves came to rely on for their internal infrastructure. The same security holes that the NSA relied on to gain access to your (or Osama bin Laden’s) email allowed gangsters to steal passwords and login credentials and credit card numbers. And ultimately these same baked-in security holes allowed Edward Snowden — who, let us remember, is merely one guy: a talented system administrator and programmer, but no Clark Kent — to rampage through their internal information systems.

The moral of the story is clear: be very cautious about poisoning the banquet you serve your guests, lest you end up accidentally ingesting it yourself.

Reset the Net on June 5th

Filed under: Liberty, Media, Technology — Tags: , , , — Nicholas @ 09:58

At Wired, Kim Zetter talks about an initiative to reclaim (some measure of) privacy on the internet:

A coalition of nearly two-dozen tech companies and civil liberties groups is launching a new fight against mass internet surveillance, hoping to battle the NSA in much the same way online campaigners pushed back on bad piracy legislation in 2012.

The new coalition, organized by Fight for the Future, is planning a Reset the Net day of action on June 5, the anniversary of the date the first Edward Snowden story broke detailing the government’s PRISM program, based on documents leaked by the former NSA contractor.

“Government spies have a weakness: they can hack anybody, but they can’t hack everybody,” the organizers behind the Reset the Net movement say in their video (above). “Folks like the NSA depend on collecting insecure data from tapped fiber. They depend on our mistakes, mistakes we can fix.”

To that end, the groups are calling on developers to add at least one NSA resistant feature to mobile apps, and on websites to add security features like SSL (Secure Socket Layer), HSTS (HTTP Strict Transport Security), and Perfect Forward Secrecy to better secure the communication of users and thwart government man-in-the-middle attacks.

Militarization of the police, pervasive surveillance, incarceration rates, and other police state trappings

It’s easy to poke fun at people who worry about the ever-growing state involvement in everyday life … well, it used to be fun until the NSA’s incredible list of surveillance programs became known. Now, paranoia is the rational state for anyone concerned with their privacy and freedom of speech. We had Godwin’s Law, which provided a useful rule of thumb for when internet arguments had passed the point of no return. This is a rare example of an argument that meets the condition of Godwin’s Law (in the infographic), yet still remains relevant.

Ephemeral apps and the NSA

Filed under: Business, Media, Technology — Tags: , , — Nicholas @ 11:21

Bruce Schneier on the rising popularity of apps that only leave your content visible briefly and then automatically removes it:

Ephemeral messaging apps such as Snapchat, Wickr and Frankly, all of which advertise that your photo, message or update will only be accessible for a short period, are on the rise. Snapchat and Frankly, for example, claim they permanently delete messages, photos and videos after 10 seconds. After that, there’s no record.

This notion is especially popular with young people, and these apps are an antidote to sites such as Facebook where everything you post lasts forever unless you take it down—and taking it down is no guarantee that it isn’t still available.

These ephemeral apps are the first concerted push against the permanence of Internet conversation. We started losing ephemeral conversation when computers began to mediate our communications. Computers naturally produce conversation records, and that data was often saved and archived.

[…]

At best, the data is recorded, used, saved and then deliberately deleted. At worst, the ephemeral nature is faked. While the apps make the posts, texts or messages unavailable to users quickly, they probably don’t erase them off their systems immediately. They certainly don’t erase them from their backup tapes, if they end up there.

The companies offering these apps might very well analyze their content and make that information available to advertisers. We don’t know how much metadata is saved. In SnapChat, users can see the metadata even though they can’t see the content and what it’s used for. And if the government demanded copies of those conversations — either through a secret NSA demand or a more normal legal process involving an employer or school — the companies would have no choice but to hand them over.

Even worse, if the FBI or NSA demanded that American companies secretly store those conversations and not tell their users, breaking their promise of deletion, the companies would have no choice but to comply.

That last bit isn’t just paranoia.
