Europe’s highest court on Tuesday struck down an international agreement that allowed companies to move digital information like people’s web search histories and social media updates between the European Union and the United States. The decision left the international operations of companies like Google and Facebook in a sort of legal limbo even as their services continued working as usual.The ruling, by the European Court of Justice, said the so-called safe harbor agreement was flawed because it allowed American government authorities to gain routine access to Europeans’ online information. The court said leaks from Edward J. Snowden, the former contractor for the National Security Agency, made it clear that American intelligence agencies had almost unfettered access to the data, infringing on Europeans’ rights to privacy. The court said data protection regulators in each of the European Union’s 28 countries should have oversight over how companies collect and use online information of their countries’ citizens. European countries have widely varying stances towards privacy.

Data protection advocates hailed the ruling. Industry executives and trade groups, though, said the decision left a huge amount of uncertainty for big companies, many of which rely on the easy flow of data for lucrative businesses like online advertising. They called on the European Commission to complete a new safe harbor agreement with the United States, a deal that has been negotiated for more than two years and could limit the fallout from the court’s decision.

Some European officials and many of the big technology companies, including Facebook and Microsoft, tried to play down the impact of the ruling. The companies kept their services running, saying that other agreements with the European Union should provide an adequate legal foundation.But those other agreements are now expected to be examined and questioned by some of Europe’s national privacy watchdogs. The potential inquiries could make it hard for companies to transfer Europeans’ information overseas under the current data arrangements. And the ruling appeared to leave smaller companies with fewer legal resources vulnerable to potential privacy violations.

The Intercept published an expose on the NSA's XKeyscore program. Along with information on the breadth and scale of the NSA's metadata collection, The Intercept revealed how the NSA relies on unencrypted cookie data to identify users. As The Intercept says: "The NSA’s ability to piggyback off of private companies’ tracking of their own users is a vital instrument that allows the agency to trace the data it collects to individual users. It makes no difference if visitors switch to public Wi-Fi networks or connect to VPNs to change their IP addresses: the tracking cookie will follow them around as long as they are using the same web browser and fail to clear their cookies." The NSA slides released by The Intercept give detailed guides to understanding the data transmitted by these cookies, as well as how to find unique machine identifiers that analysts can use to differentiate between multiple machines using the same IP address. We've written before about how spy agencies piggyback on social media account data to find Internet users' names or other identifying info, and these slides drive home the point that HTTP cookies leave users vulnerable to government surveillance, since any intermediary (or spy agency) can read the sensitive data they contain.

Worse yet, most of the time these identifying cookies come from third-party sources on webpages, and users have no meaningful way to opt out of receiving them (short of blocking all third party cookies) since advertisers (the main server of these types of cookies) refuse to honor the Do Not Track header.  Browser makers could help address this sort of non-consensual tracking by both advertisers and the NSA with some simple technical changes—changes that have been shown to reduce the number of third party cookies received by 67%. So far, though, they've been unwilling to build privacy protecting features in by default. Until they do, the best way for users to protect themselves is by installing a privacy protecting app like Privacy Badger, which is designed to block these types of uniquely identifying tracking cookies, or HTTPS Everywhere to block the transmission of HTTP cookies.

What does it look like when a society loses its sense of privacy? <div><a href="http://pubads.g.doubleclick.net/gampad/jump?iu=%2F4624%2FTheAtlanticOnline%2Fchannel_technology&t=src%3Dblog%26by%3Drobinson-meyer%26title%3Damerican-surveillance-now-threatens-american-business%26pos%3Din-article&sz=300x250&c=285899172&tile=1" title=""><img style="border:none;" src="http://pubads.g.doubleclick.net/gampad/ad?iu=%2F4624%2FTheAtlanticOnline%2Fchannel_technology&t=src%3Dblog%26by%3Drobinson-meyer%26title%3Damerican-surveillance-now-threatens-american-business%26pos%3Din-article&sz=300x250&c=285899172&tile=1" alt="" /></a></div>In the almost 18 months since the Snowden files first received coverage, writers and critics have had to guess at the answer. Does a certain trend, consumer complaint, or popular product epitomize some larger shift? Is trust in tech companies eroding—or is a subset just especially vocal about it? Polling would make those answers clear, but polling so far has been… confused. A new study, conducted by the Pew Internet Project last January and released last week, helps make the average American’s view of his or her privacy a little clearer. And their confidence in their own privacy is ... low. The study's findings—and the statistics it reports—stagger. Vast majorities of Americans are uncomfortable with how the government uses their data, how private companies use and distribute their data, and what the government does to regulate those companies. No summary can equal a recounting of the findings. Americans are displeased with government surveillance en masse:   

A new study finds that a vast majority of Americans trust neither the government nor tech companies with their personal data.

According to the study, 70 percent of Americans are “at least somewhat concerned” with the government secretly obtaining information they post to social networking sites. Eighty percent of respondents agreed that “Americans should be concerned” with government surveillance of telephones and the web. They are also uncomfortable with how private corporations use their data: Ninety-one percent of Americans believe that “consumers have lost control over how personal information is collected and used by companies,” according to the study. Eighty percent of Americans who use social networks “say they are concerned about third parties like advertisers or businesses accessing the data they share on these sites.” And even though they’re squeamish about the government’s use of data, they want it to regulate tech companies and data brokers more strictly: 64 percent wanted the government to do more to regulate private data collection. Since June 2013, American politicians and corporate leaders have fretted over how much the leaks would cost U.S. businesses abroad.

The House of Representatives has passed the USA Freedom Act, which represents a significant down payment on broader government surveillance reform. We need as many people as possible speaking up to make sure that the Senate says YES to the USA Freedom Act.

OPERATION: Fax Big Brother Congress is rushing toward a vote on CISA, the worst spying bill yet. CISA would grant sweeping legal immunity to giant companies like Facebook and Google, allowing them to do almost anything they want with your data. In exchange, they'll share even more of your personal information with the government, all in the name of "cybersecurity." CISA won't stop hackers — Congress is stuck in 1984 and doesn't understand modern technology. So this week we're sending them thousands of faxes — technology that is hopefully old enough for them to understand. Stop CISA. Send a fax now!

(Any tweet w/ #faxbigbrother will get faxed too!) Your email is only shown in your fax to Congress. We won't add you to any mailing lists.

CISA: the dirty deal between government and corporate giants. It's the dirty deal that lets much of government from the NSA to local police get your private data from your favorite websites and lets them use it without due process. The government is proposing a massive bribe—they will give corporations immunity for breaking virtually any law if they do so while providing the NSA, DHS, DEA, and local police surveillance access to everyone's data in exchange for getting away with crimes, like fraud, money laundering, or illegal wiretapping. Specifically it incentivizes companies to automatically and simultaneously transfer your data to the DHS, NSA, FBI, and local police with all of your personally-indentifying information by giving companies legal immunity (notwithstanding any law), and on top of that, you can't use the Freedom of Information Act to find out what has been shared.

HERE WAS A SIMPLE AIM at the heart of the top-secret program: Record the website browsing habits of “every visible user on the Internet.” Before long, billions of digital records about ordinary people’s online activities were being stored every day. Among them were details cataloging visits to porn, social media and news websites, search engines, chat forums, and blogs. The mass surveillance operation — code-named KARMA POLICE — was launched by British spies about seven years ago without any public debate or scrutiny. It was just one part of a giant global Internet spying apparatus built by the United Kingdom’s electronic eavesdropping agency, Government Communications Headquarters, or GCHQ. The revelations about the scope of the British agency’s surveillance are contained in documents obtained by The Intercept from National Security Agency whistleblower Edward Snowden. Previous reports based on the leaked files have exposed how GCHQ taps into Internet cables to monitor communications on a vast scale, but many details about what happens to the data after it has been vacuumed up have remained unclear.

Amid a renewed push from the U.K. government for more surveillance powers, more than two dozen documents being disclosed today by The Intercept reveal for the first time several major strands of GCHQ’s existing electronic eavesdropping capabilities.

The surveillance is underpinned by an opaque legal regime that has authorized GCHQ to sift through huge archives of metadata about the private phone calls, emails and Internet browsing logs of Brits, Americans, and any other citizens — all without a court order or judicial warrant

Canada’s leading surveillance agency is monitoring millions of Internet users’ file downloads in a dragnet search to identify extremists, according to top-secret documents. The covert operation, revealed Wednesday by CBC News in collaboration with The Intercept, taps into Internet cables and analyzes records of up to 15 million downloads daily from popular websites commonly used to share videos, photographs, music, and other files. The revelations about the spying initiative, codenamed LEVITATION, are the first from the trove of files provided by National Security Agency whistleblower Edward Snowden to show that the Canadian government has launched its own globe-spanning Internet mass surveillance system. According to the documents, the LEVITATION program can monitor downloads in several countries across Europe, the Middle East, North Africa, and North America. It is led by the Communications Security Establishment, or CSE, Canada’s equivalent of the NSA. (The Canadian agency was formerly known as “CSEC” until a recent name change.)

The latest disclosure sheds light on Canada’s broad existing surveillance capabilities at a time when the country’s government is pushing for a further expansion of security powers following attacks in Ottawa and Quebec last year. Ron Deibert, director of University of Toronto-based Internet security think tank Citizen Lab, said LEVITATION illustrates the “giant X-ray machine over all our digital lives.” “Every single thing that you do – in this case uploading/downloading files to these sites – that act is being archived, collected and analyzed,” Deibert said, after reviewing documents about the online spying operation for CBC News. David Christopher, a spokesman for Vancouver-based open Internet advocacy group OpenMedia.ca, said the surveillance showed “robust action” was needed to rein in the Canadian agency’s operations.

In a top-secret PowerPoint presentation, dated from mid-2012, an analyst from the agency jokes about how, while hunting for extremists, the LEVITATION system gets clogged with information on innocuous downloads of the musical TV series Glee. CSE finds some 350 “interesting” downloads each month, the presentation notes, a number that amounts to less than 0.0001 per cent of the total collected data. The agency stores details about downloads and uploads to and from 102 different popular file-sharing websites, according to the 2012 document, which describes the collected records as “free file upload,” or FFU, “events.” Only three of the websites are named: RapidShare, SendSpace, and the now defunct MegaUpload.

ne new email service promising "end-to-end" encryption launched on Friday, and others are being developed while major services such as Google Gmail and Yahoo Mail have stepped up security measures.A major catalyst for email encryption were revelations about widespread online surveillance in documents leaked by Edward Snowden, the former National Security Agency contractor."A lot of people were upset with those revelations, and that coalesced into this effort," said Jason Stockman, a co-developer of ProtonMail, a new encrypted email service which launched Friday with collaboration of scientists from Harvard, the Massachusetts Institute of Technology and the European research lab CERN.Stockman said ProtonMail aims to be as user-friendly as the major commercial services, but with extra security, and with its servers located in Switzerland to make it more difficult for US law enforcement to access.

"Our vision is to make encryption and privacy mainstream by making it easy to use," Stockman told AFP. "There's no installation. Everything happens behind the scenes automatically."Even though email encryption using special codes or keys, a system known as PGP, has been around for two decades, "it was so complicated," and did not gain widespread adoption, Stockman said.After testing over the past few months, ProtonMail went public Friday using a "freemium" model a basic account will be free with some added features for a paid account.

As our users from China, Iran, Russia, and other countries around the world have shown us in the past months, ProtonMail is an important tool for freedom of speech and we are happy to finally be able to provide this to the whole world," the company said in a blog post.Google and Yahoo recently announced efforts to encrypt their email communications, but some specialists say the effort falls short."These big companies don't want to encrypt your stuff because they spy on you, too," said Bruce Schneier, a well-known cryptographer and author who is chief technology officer for CO3 Systems."Hopefully, the NSA debate is creating incentives for people to build more encryption."Stockman said that with services like Gmail, even if data is encrypted, "they have the key right next to it if you have the key and lock next to each other, so it's pretty much useless."

British and Canadian spy agencies accumulated sensitive data on smartphone users, including location, app preferences, and unique device identifiers, by piggybacking on ubiquitous software from advertising and analytics companies, according to a document obtained by NSA whistleblower Edward Snowden. The document, included in a trove of Snowden material released by Der Spiegel on January 17, outlines a secret program run by the intelligence agencies called BADASS. The German newsweekly did not write about the BADASS document, attaching it to a broader article on cyberwarfare. According to The Intercept‘s analysis of the document, intelligence agents applied BADASS software filters to streams of intercepted internet traffic, plucking from that traffic unencrypted uploads from smartphones to servers run by advertising and analytics companies.

Programmers frequently embed code from a handful of such companies into their smartphone apps because it helps them answer a variety of questions: How often does a particular user open the app, and at what time of day? Where does the user live? Where does the user work? Where is the user right now? What’s the phone’s unique identifier? What version of Android or iOS is the device running? What’s the user’s IP address? Answers to those questions guide app upgrades and help target advertisements, benefits that help explain why tracking users is not only routine in the tech industry but also considered a best practice. For users, however, the smartphone data routinely provided to ad and analytics companies represents a major privacy threat. When combined together, the information fragments can be used to identify specific users, and when concentrated in the hands of a small number of companies, they have proven to be irresistibly convenient targets for those engaged in mass surveillance. Although the BADASS presentation appears to be roughly four years old, at least one player in the mobile advertising and analytics space, Google, acknowledges that its servers still routinely receive unencrypted uploads from Google code embedded in apps.

Less than a week after the attacks in Paris — while the public and policymakers were still reeling, and the investigation had barely gotten off the ground — Cy Vance, Manhattan’s District Attorney, released a policy paper calling for legislation requiring companies to provide the government with backdoor access to their smartphones and other mobile devices. This is the first concrete proposal of this type since September 2014, when FBI Director James Comey reignited the “Crypto Wars” in response to Apple’s and Google’s decisions to use default encryption on their smartphones. Though Comey seized on Apple’s and Google’s decisions to encrypt their devices by default, his concerns are primarily related to end-to-end encryption, which protects communications that are in transit. Vance’s proposal, on the other hand, is only concerned with device encryption, which protects data stored on phones. It is still unclear whether encryption played any role in the Paris attacks, though we do know that the attackers were using unencrypted SMS text messages on the night of the attack, and that some of them were even known to intelligence agencies and had previously been under surveillance. But regardless of whether encryption was used at some point during the planning of the attacks, as I lay out below, prohibiting companies from selling encrypted devices would not prevent criminals or terrorists from being able to access unbreakable encryption. Vance’s primary complaint is that Apple’s and Google’s decisions to provide their customers with more secure devices through encryption interferes with criminal investigations. He claims encryption prevents law enforcement from accessing stored data like iMessages, photos and videos, Internet search histories, and third party app data. He makes several arguments to justify his proposal to build backdoors into encrypted smartphones, but none of them hold water.

Before addressing the major privacy, security, and implementation concerns that his proposal raises, it is worth noting that while an increase in use of fully encrypted devices could interfere with some law enforcement investigations, it will help prevent far more crimes — especially smartphone theft, and the consequent potential for identity theft. According to Consumer Reports, in 2014 there were more than two million victims of smartphone theft, and nearly two-thirds of all smartphone users either took no steps to secure their phones or their data or failed to implement passcode access for their phones. Default encryption could reduce instances of theft because perpetrators would no longer be able to break into the phone to steal the data.

Vance argues that creating a weakness in encryption to allow law enforcement to access data stored on devices does not raise serious concerns for security and privacy, since in order to exploit the vulnerability one would need access to the actual device. He considers this an acceptable risk, claiming it would not be the same as creating a widespread vulnerability in encryption protecting communications in transit (like emails), and that it would be cheap and easy for companies to implement. But Vance seems to be underestimating the risks involved with his plan. It is increasingly important that smartphones and other devices are protected by the strongest encryption possible. Our devices and the apps on them contain astonishing amounts of personal information, so much that an unprecedented level of harm could be caused if a smartphone or device with an exploitable vulnerability is stolen, not least in the forms of identity fraud and credit card theft. We bank on our phones, and have access to credit card payments with services like Apple Pay. Our contact lists are stored on our phones, including phone numbers, emails, social media accounts, and addresses. Passwords are often stored on people’s phones. And phones and apps are often full of personal details about their lives, from food diaries to logs of favorite places to personal photographs. Symantec conducted a study, where the company spread 50 “lost” phones in public to see what people who picked up the phones would do with them. The company found that 95 percent of those people tried to access the phone, and while nearly 90 percent tried to access private information stored on the phone or in other private accounts such as banking services and email, only 50 percent attempted contacting the owner.

If we’ve learned one thing from the Snowden revelations, it’s that what can be spied on will be spied on. Since the advent of what used to be known as the World Wide Web, it has been a relatively simple matter for network attackers—whether it’s the NSA, Chinese intelligence, your employer, your university, abusive partners, or teenage hackers on the same public WiFi as you—to spy on almost everything you do online. HTTPS, the technology that encrypts traffic between browsers and websites, fixes this problem—anyone listening in on that stream of data between you and, say, your Gmail window or bank’s web site would get nothing but useless random characters—but is woefully under-used. The ambitious new non-profit Let’s Encrypt aims to make the process of deploying HTTPS not only fast, simple, and free, but completely automatic. If it succeeds, the project will render vast regions of the internet invisible to prying eyes.

Encryption also prevents attackers from tampering with or impersonating legitimate websites. For example, the Chinese government censors specific pages on Wikipedia, the FBI impersonated The Seattle Times to get a suspect to click on a malicious link, and Verizon and AT&T injected tracking tokens into mobile traffic without user consent. HTTPS goes a long way in preventing these sorts of attacks. And of course there’s the NSA, which relies on the limited adoption of HTTPS to continue to spy on the entire internet with impunity. If companies want to do one thing to meaningfully protect their customers from surveillance, it should be enabling encryption on their websites by default.

Let’s Encrypt, which was announced this week but won’t be ready to use until the second quarter of 2015, describes itself as “a free, automated, and open certificate authority (CA), run for the public’s benefit.” It’s the product of years of work from engineers at Mozilla, Cisco, Akamai, Electronic Frontier Foundation, IdenTrust, and researchers at the University of Michigan. (Disclosure: I used to work for the Electronic Frontier Foundation, and I was aware of Let’s Encrypt while it was being developed.) If Let’s Encrypt works as advertised, deploying HTTPS correctly and using all of the best practices will be one of the simplest parts of running a website. All it will take is running a command. Currently, HTTPS requires jumping through a variety of complicated hoops that certificate authorities insist on in order prove ownership of domain names. Let’s Encrypt automates this task in seconds, without requiring any human intervention, and at no cost.

The movement to encrypt the web has reached a milestone. As of earlier this month, approximately half of Internet traffic is now protected by HTTPS. In other words, we are halfway to a web safer from the eavesdropping, content hijacking, cookie stealing, and censorship that HTTPS can protect against. Mozilla recently reported that the average volume of encrypted web traffic on Firefox now surpasses the average unencrypted volume

Google Chrome’s figures on HTTPS usage are consistent with that finding, showing that over 50% of of all pages loaded are protected by HTTPS across different operating systems.

This milestone is a combination of HTTPS implementation victories: from tech giants and large content providers, from small websites, and from users themselves.

Yahoo Chief Information Security Officer Alex Stamos announced today at Black Hat 2014 that starting in the fall of this year, the purple-hued company will begin giving users the option of seamlessly wrapping their e-mails in PGP encryption. According to Kashmir Hill at Forbes, the encryption capability will be offered through a modified version of the same End-to-End browser plug-in that Google uses for PGP in Gmail. The announcement was tweeted by Yan Zhu, who has reportedly been hired by Yahoo to adapt End-to-End for use with Yahoo Mail. Zhu formerly worked as an engineer at the Electronic Frontier Foundation, an organization that has consistently been outspoken in its call for the widespread use of encryption throughout the Web and the Internet in general.

"Today at the first annual Code Conference, Microsoft demonstrated its new real-time translation in Skype publicly for the first time. Gurdeep Pall, Microsoft's VP of Skype and Lync, compares the technology to Star Trek's Universal Translator. During the demonstration, Pall converses in English with a coworker in Germany who is speaking German. 'Skype Translator results from decades of work by the industry, years of work by our researchers, and now is being developed jointly by the Skype and Microsoft Translator teams. The demo showed near real-time audio translation from English to German and vice versa, combining Skype voice and IM technologies with Microsoft Translator, and neural network-based speech recognition.'"

The President of Brazil, Dilma Rousseff announces publicly the creation of a world internet system INDEPENDENT from US and Britain ( the “US-centric internet”). Not many understand that, while the immediate trigger for the decision (coupled with the cancellation of a summit with the US president) was the revelations on NSA spying, the reason why Rousseff can take such a historic step is that the alternative infrastructure: The BRICS cable from Vladivostock, Russia  to Shantou, China to Chennai, India  to Cape Town, South Africa  to Fortaleza, Brazil,  is being built and it’s, actually, in its final phase of implementation. No amount of provocation and attempted “Springs” destabilizations and Color Revolution in the Middle East, Russia or Brazil can stop this process.  The huge submerged part of the BRICS plan is not yet known by the broader public.

Nonetheless it is very real and extremely effective. So real that international investors are now jumping with both feet on this unprecedented real economy opportunity. The change… has already happened. Brazil plans to divorce itself from the U.S.-centric Internet over Washington’s widespread online spying, a move that many experts fear will be a potentially dangerous first step toward politically fracturing a global network built with minimal interference by governments. President Dilma Rousseff has ordered a series of measures aimed at greater Brazilian online independence and security following revelations that the U.S. National Security Agency intercepted her communications, hacked into the state-owned Petrobras oil company’s network and spied on Brazilians who entrusted their personal data to U.S. tech companies such as Facebook and Google.

A new study says that the U.S. tech industry is likely to lose more than $35 billion from foreign customers by 2016 because of concerns over government surveillance.“In short, foreign customers are shunning U.S. companies,” the authors of a new study from the Information Technology and Innovation Foundation write.ADVERTISEMENT“The U.S. government’s failure to reform many of the NSA’s surveillance programs has damaged the competitiveness of the U.S. tech sector and cost it a portion of the global market share,” they said.The think tank’s report found that the cost to the tech sector associated with ongoing concerns over surveillance programs run out of the U.S. was likely to “far exceed” $35 billion by 2016, an earlier estimate set by the group.

The group said that lawmakers must enact additional reforms to surveillance policy if they wish to help the tech sector regain the trust of foreign customers. That includes opposing “backdoors,” which allow law enforcement to access otherwise encrypted data, and signing off on trade agreements, including the controversial Trans-Pacific Partnership, that “ban digital protectionism.”The study’s authors found that the revelations about broad U.S. surveillance programs acted as a justification for foreign policymakers to enact protectionist policies aimed at aiding their own domestic technology sectors.Foreign companies have also used the information about U.S. surveillance programs to their advantage.“Some European companies have begun to highlight where their digital services are hosted as an alternative to U.S. companies,” the authors write.

American companies, they found, have lost contracts to foreign competitors over fears about mass surveillance.Earlier this month, President Obama signed the USA Freedom Act, a bill that reformed the three Patriot Act provisions that authorized the bulk, warrantless collection of Americans’ phone records. The bill was widely supported by technology companies, including giants like Apple and Google.

As fast as it can, Google is sealing up cracks in its systems that Edward J. Snowden revealed the N.S.A. had brilliantly exploited. It is encrypting more data as it moves among its servers and helping customers encode their own emails. Facebook, Microsoft and Yahoo are taking similar steps.

After years of cooperating with the government, the immediate goal now is to thwart Washington — as well as Beijing and Moscow. The strategy is also intended to preserve business overseas in places like Brazil and Germany that have threatened to entrust data only to local providers. Google, for example, is laying its own fiber optic cable under the world’s oceans, a project that began as an effort to cut costs and extend its influence, but now has an added purpose: to assure that the company will have more control over the movement of its customer data.

A year after Mr. Snowden’s revelations, the era of quiet cooperation is over. Telecommunications companies say they are denying requests to volunteer data not covered by existing law. A.T.&T., Verizon and others say that compared with a year ago, they are far more reluctant to cooperate with the United States government in “gray areas” where there is no explicit requirement for a legal warrant.

Email encryption in transit Many email providers don’t encrypt messages while they’re in transit. When you send or receive emails with one of these providers, these messages are as open to snoopers as a postcard in the mail. A growing number of email providers are working to change that, by encrypting messages sent to and from our services using Transport Layer Security (TLS). When an email is encrypted in transit with TLS, it makes it harder for others to read what you’re sending. The data below explains the current state of email encryption in transit.

Generally speaking, use of encryption in transit increases over time, as more providers enable and maintain their support. Factors such as varying volumes of email may explain other fluctuations.

Below is the percentage of email encrypted for the top domains in terms of volume of email to and from Gmail, in alphabetical order.
