At the Web 2.0 Expo, Tim O'Reilly predicts that Microsoft will emerge as a leading proponent of the open Web, despite the company's tradition of fostering its own proprietary operating systems and development languages. O'Reilly says Microsoft's recent deals to index Twitter tweets and use Wolfram Alpha's APIs for computational data show a shift in its willingness to work with other Web companies. Moreover, the Windows Azure cloud computing operating system is designed to work with open-source technology.

For more than two years, researchers and rights activists have tracked the proliferation and abuse of computer spyware that can watch people in their homes and intercept their e-mails. Now they’ve built a tool that can help the targets protect themselves.The free, downloadable software, called Detekt, searches computers for the presence of malicious programs that have been built to evade detection. The spyware ranges from government-grade products used by intelligence and police agencies to hacker staples known as RATs—remote administration tools. Detekt, which was developed by security researcher Claudio Guarnieri, is being released in a partnership with advocacy groups Amnesty International, Digitale Gesellschaft, the Electronic Frontier Foundation, and Privacy International.Guarnieri says his tool finds hidden spy programs by seeking unique patterns on computers that indicate a specific malware is running. He warns users not to expect his program (which is available only for Windows machines) to find all spyware, and notes that the release of Detekt could spur malware developers to further cloak their code.

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.

The benefits of using HTTPS are obvious when you think about protecting secret information you send over the internet, like passwords and credit card numbers. It also helps protect information like what you search for in Google, what articles you read, what prescription medicine you take, and messages you send to colleagues, friends, and family from being monitored by hackers or authorities. But there are less obvious benefits as well. Websites that don’t use HTTPS are vulnerable to “session hijacking,” where attackers can take over your account even if they don’t know your password. When you download software without encryption, sophisticated attackers can secretly replace the download with malware that hacks your computer as soon as you try installing it.

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.

 The United States Telecom Association has filed a lawsuit to overturn the net neutrality rules set by the Federal Communications Commission this past February. In its Monday morning Press Release USTelecom, who represents Verizon and AT&T among others, said it filed a lawsuit in the US Court of Appeals for the District of Columbia joining a similar law suit filed by Alamo Broadband Inc.

The Federal Communications Commission (FCC) published its net neutrality rules in the Federal Register on Monday and, according to procedure, that began a 60-day countdown until they go into effect (June 12). Their publication also opened a 30-day window for Internet service providers to appeal.  USTelecom and Alamo Broadband wasted no time.  USTelecom filed a previous action preserving the issue according to local court rule prior to the formal petition in March.

The rules, which were voted on in February, reclassify broadband under Title II of the 1934 Communications Act and require that ISPs transmit all Web traffic at the same speed. Over 400 pages long, USTelecom filed a CD of the rules as an exhibit with its action. This suit is predicted to be the first of many, as broadband groups like AT&T to congressional Republicans have signaled that they plan to fight the decision.

Micah Lee: What are some operational security practices you think everyone should adopt? Just useful stuff for average people. Edward Snowden: [Opsec] is important even if you’re not worried about the NSA. Because when you think about who the victims of surveillance are, on a day-to-day basis, you’re thinking about people who are in abusive spousal relationships, you’re thinking about people who are concerned about stalkers, you’re thinking about children who are concerned about their parents overhearing things. It’s to reclaim a level of privacy. The first step that anyone could take is to encrypt their phone calls and their text messages. You can do that through the smartphone app Signal, by Open Whisper Systems. It’s free, and you can just download it immediately. And anybody you’re talking to now, their communications, if it’s intercepted, can’t be read by adversaries. [Signal is available for iOS and Android, and, unlike a lot of security tools, is very easy to use.] You should encrypt your hard disk, so that if your computer is stolen the information isn’t obtainable to an adversary — pictures, where you live, where you work, where your kids are, where you go to school. [I’ve written a guide to encrypting your disk on Windows, Mac, and Linux.] Use a password manager. One of the main things that gets people’s private information exposed, not necessarily to the most powerful adversaries, but to the most common ones, are data dumps. Your credentials may be revealed because some service you stopped using in 2007 gets hacked, and your password that you were using for that one site also works for your Gmail account. A password manager allows you to create unique passwords for every site that are unbreakable, but you don’t have the burden of memorizing them. [The password manager KeePassX is free, open source, cross-platform, and never stores anything in the cloud.]

The other thing there is two-factor authentication. The value of this is if someone does steal your password, or it’s left or exposed somewhere … [two-factor authentication] allows the provider to send you a secondary means of authentication — a text message or something like that. [If you enable two-factor authentication, an attacker needs both your password as the first factor and a physical device, like your phone, as your second factor, to login to your account. Gmail, Facebook, Twitter, Dropbox, GitHub, Battle.net, and tons of other services all support two-factor authentication.]

We should armor ourselves using systems we can rely on every day. This doesn’t need to be an extraordinary lifestyle change. It doesn’t have to be something that is disruptive. It should be invisible, it should be atmospheric, it should be something that happens painlessly, effortlessly. This is why I like apps like Signal, because they’re low friction. It doesn’t require you to re-order your life. It doesn’t require you to change your method of communications. You can use it right now to talk to your friends.

For most of the past six weeks, the biggest story out of Silicon Valley was Apple’s battle with the FBI over a federal order to unlock the iPhone of a mass shooter. The company’s refusal touched off a searing debate over privacy and security in the digital age. But this morning, at a small office in Mountain View, California, three guys made the scope of that enormous debate look kinda small. Mountain View is home to WhatsApp, an online messaging service now owned by tech giant Facebook, that has grown into one of the world’s most important applications. More than a billion people trade messages, make phone calls, send photos, and swap videos using the service. This means that only Facebook itself runs a larger self-contained communications network. And today, the enigmatic founders of WhatsApp, Brian Acton and Jan Koum, together with a high-minded coder and cryptographer who goes by the pseudonym Moxie Marlinspike, revealed that the company has added end-to-end encryption to every form of communication on its service.

This means that if any group of people uses the latest version of WhatsApp—whether that group spans two people or ten—the service will encrypt all messages, phone calls, photos, and videos moving among them. And that’s true on any phone that runs the app, from iPhones to Android phones to Windows phones to old school Nokia flip phones. With end-to-end encryption in place, not even WhatsApp’s employees can read the data that’s sent across its network. In other words, WhatsApp has no way of complying with a court order demanding access to the content of any message, phone call, photo, or video traveling through its service. Like Apple, WhatsApp is, in practice, stonewalling the federal government, but it’s doing so on a larger front—one that spans roughly a billion devices.

The FBI and the Justice Department declined to comment for this story. But many inside the government and out are sure to take issue with the company’s move. In late 2014, WhatsApp encrypted a portion of its network. In the months since, its service has apparently been used to facilitate criminal acts, including the terrorist attacks on Paris last year. According to The New York Times, as recently as this month, the Justice Department was considering a court case against the company after a wiretap order (still under seal) ran into WhatsApp’s end-to-end encryption. “The government doesn’t want to stop encryption,” says Joseph DeMarco, a former federal prosecutor who specializes in cybercrime and has represented various law enforcement agencies backing the Justice Department and the FBI in their battle with Apple. “But the question is: what do you do when a company creates an encryption system that makes it impossible for court-authorized search warrants to be executed? What is the reasonable level of assistance you should ask from that company?”

Internet censors have a new strategy in their bid to block applications and websites: pressuring the large cloud providers that host them. These providers have concerns that are much broader than the targets of censorship efforts, so they have the choice of either standing up to the censors or capitulating in order to maximize their business. Today’s internet largely reflects the dominance of a handful of companies behind the cloud services, search engines and mobile platforms that underpin the technology landscape. This new centralization radically tips the balance between those who want to censor parts of the internet and those trying to evade censorship. When the profitable answer is for a software giant to acquiesce to censors' demands, how long can internet freedom last? The recent battle between the Russian government and the Telegram messaging app illustrates one way this might play out. Russia has been trying to block Telegram since April, when a Moscow court banned it after the company refused to give Russian authorities access to user messages. Telegram, which is widely used in Russia, works on both iPhone and Android, and there are Windows and Mac desktop versions available. The app offers optional end-to-end encryption, meaning that all messages are encrypted on the sender's phone and decrypted on the receiver's phone; no part of the network can eavesdrop on the messages. Since then, Telegram has been playing cat-and-mouse with the Russian telecom regulator Roskomnadzor by varying the IP address the app uses to communicate. Because Telegram isn't a fixed website, it doesn't need a fixed IP address. Telegram bought tens of thousands of IP addresses and has been quickly rotating through them, staying a step ahead of censors. Cleverly, this tactic is invisible to users. The app never sees the change, or the entire list of IP addresses, and the censor has no clear way to block them all. A week after the court ban, Roskomnadzor countered with an unprecedented move of its own: blocking 19 million IP addresses, many on Amazon Web Services and Google Cloud. The collateral damage was widespread: The action inadvertently broke many other web services that use those platforms, and Roskomnadzor scaled back after it became clear that its action had affected services critical for Russian business. Even so, the censor is still blocking millions of IP addresses.

The Supreme Court on Friday handed down what is arguably the most consequential privacy decision of the digital age, ruling that police need a warrant before they can seize people’s sensitive location information stored by cellphone companies. The case specifically concerns the privacy of cellphone location data, but the ruling has broad implications for government access to all manner of information collected about people and stored by the purveyors of popular technologies. In its decision, the court rejects the government’s expansive argument that people lose their privacy rights merely by using those technologies. Carpenter v. U.S., which was argued by the ACLU, involves Timothy Carpenter, who was convicted in 2013 of a string of burglaries in Detroit. To tie Carpenter to the burglaries, FBI agents obtained — without seeking a warrant — months’ worth of his location information from Carpenter’s cellphone company. They got almost 13,000 data points tracking Carpenter’s whereabouts during that period, revealing where he slept, when he attended church, and much more. Indeed, as Chief Justice John Roberts wrote in Friday’s decision, “when the Government tracks the location of a cell phone it achieves near perfect surveillance, as if it had attached an ankle monitor to the phone’s user.”.

The ACLU argued the agents had violated Carpenter’s Fourth Amendment rights when they obtained such detailed records without a warrant based on probable cause. In a decision written by Chief Justice John Roberts, the Supreme Court agreed, recognizing that the Fourth Amendment must apply to records of such unprecedented breadth and sensitivity: Mapping a cell phone’s location over the course of 127 days provides an all-encompassing record of the holder’s whereabouts. As with GPS information, the timestamped data provides an intimate window into a person’s life, revealing not only his particular movements, but through them his ‘familial, political, professional, religious, and sexual associations.’

The government’s argument that it needed no warrant for these records extends far beyond cellphone location information, to any data generated by modern technologies and held by private companies rather than in our own homes or pockets. To make their case, government lawyers relied on an outdated, 1970s-era legal doctrine that says that once someone shares information with a “third party” — in Carpenter’s case, a cellphone company — that data is no longer protected by the Fourth Amendment. The Supreme Court made abundantly clear that this doctrine has its limits and cannot serve as a carte blanche for the government seizure of any data of its choosing without judicial oversight.
