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.

In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce "export-grade" (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA "black budget" (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it's likely NSA has been breaking 1024-bit Diffie-Hellman for some time now. The good news is, in the time since this research was originally published, the major browser vendors (IE, Chrome, and Firefox) have removed support for 512-bit Diffie-Hellman, addressing the biggest vulnerability. However, 1024-bit Diffie-Hellman remains supported for the forseeable future despite its vulnerability to NSA surveillance. In this post, we present some practical tips to protect yourself from the surveillance machine, whether you're using a web browser, an SSH client, or VPN software. Disclaimer: This is not a complete guide, and not all software is covered.

The White House on Tuesday ended two years of ignoring a hugely popular whitehouse.gov petition calling for NSA whistleblower Edward Snowden to be “immediately issued a full, free, and absolute pardon,” saying thanks for signing, but no. “We live in a dangerous world,” Lisa Monaco, President Obama’s adviser on homeland security and terrorism, said in a statement. More than 167,000 people signed the petition, which surpassed the 100,000 signatures that the White House’s “We the People” website said would garner a guaranteed response on June 24, 2013. In Tuesday’s response, the White House acknowledged that “This is an issue that many Americans feel strongly about.”

Monaco then explained her position: “Instead of constructively addressing these issues, Mr. Snowden’s dangerous decision to steal and disclose classified information had severe consequences for the security of our country and the people who work day in and day out to protect it.” Snowden didn’t actually disclose any classified information — news organizations including the Guardian, Washington Post, New York Times and The Intercept did the disclosing. And the Obama administration has yet to specify any “severe consequences” that can be independently confirmed.

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.

The National Security Agency and its British counterpart, Government Communications Headquarters, have worked to subvert anti-virus and other security software in order to track users and infiltrate networks, according to documents from NSA whistleblower Edward Snowden. The spy agencies have reverse engineered software products, sometimes under questionable legal authority, and monitored web and email traffic in order to discreetly thwart anti-virus software and obtain intelligence from companies about security software and users of such software. One security software maker repeatedly singled out in the documents is Moscow-based Kaspersky Lab, which has a holding registered in the U.K., claims more than 270,000 corporate clients, and says it protects more than 400 million people with its products. British spies aimed to thwart Kaspersky software in part through a technique known as software reverse engineering, or SRE, according to a top-secret warrant renewal request. The NSA has also studied Kaspersky Lab’s software for weaknesses, obtaining sensitive customer information by monitoring communications between the software and Kaspersky servers, according to a draft top-secret report. The U.S. spy agency also appears to have examined emails inbound to security software companies flagging new viruses and vulnerabilities.

The efforts to compromise security software were of particular importance because such software is relied upon to defend against an array of digital threats and is typically more trusted by the operating system than other applications, running with elevated privileges that allow more vectors for surveillance and attack. Spy agencies seem to be engaged in a digital game of cat and mouse with anti-virus software companies; the U.S. and U.K. have aggressively probed for weaknesses in software deployed by the companies, which have themselves exposed sophisticated state-sponsored malware.

The requested warrant, provided under Section 5 of the U.K.’s 1994 Intelligence Services Act, must be renewed by a government minister every six months. The document published today is a renewal request for a warrant valid from July 7, 2008 until January 7, 2009. The request seeks authorization for GCHQ activities that “involve modifying commercially available software to enable interception, decryption and other related tasks, or ‘reverse engineering’ software.”

Now, as the Internet revolution unfolds, we are seeing not merely an extension of mind but a unity of mind and machine, two networks coming together as one. Our smaller brains are in a quest to bypass nature's intent and grow larger by proxy. It is not a stretch of the imagination to believe we will one day have all of the world's information embedded in our minds via the Internet.

BCI stands for brain-computer interface, and Jan is one of only a few people on earth using this technology, through two implanted chips attached directly to the neurons in her brain. The first human brain implant was conceived of by John Donoghue, a neuroscientist at Brown University, and implanted in a paralyzed man in 2004. These dime-sized computer chips use a technology called BrainGate that directly connects the mind to computers and the Internet. Having served as chairman of the BrainGate company, I have personally witnessed just how profound this innovation is. BrainGate is an invention that allows people to control electrical devices with nothing but their thoughts. The BrainGate chip is implanted in the brain and attached to connectors outside of the skull, which are hooked up to computers that, in Jan Scheuermann's case, are linked to a robotic arm. As a result, Scheuermann can feed herself chocolate by controlling the robotic arm with nothing but her thoughts.

Mind meld But imagine the ways in which the world will change when any of us, disabled or not, can connect our minds to computers.

Nearly 20 years after Congress passed the Electronic Freedom of Information Act Amendments (E-FOIA), only 40 percent of agencies have followed the law's instruction for systematic posting of records released through FOIA in their electronic reading rooms, according to a new FOIA Audit released today by the National Security Archive at www.nsarchive.org to mark Sunshine Week. The Archive team audited all federal agencies with Chief FOIA Officers as well as agency components that handle more than 500 FOIA requests a year — 165 federal offices in all — and found only 67 with online libraries populated with significant numbers of released FOIA documents and regularly updated.

Congress called on agencies to embrace disclosure and the digital era nearly two decades ago, with the passage of the 1996 "E-FOIA" amendments. The law mandated that agencies post key sets of records online, provide citizens with detailed guidance on making FOIA requests, and use new information technology to post online proactively records of significant public interest, including those already processed in response to FOIA requests and "likely to become the subject of subsequent requests." Congress believed then, and openness advocates know now, that this kind of proactive disclosure, publishing online the results of FOIA requests as well as agency records that might be requested in the future, is the only tenable solution to FOIA backlogs and delays. Thus the National Security Archive chose to focus on the e-reading rooms of agencies in its latest audit. Even though the majority of federal agencies have not yet embraced proactive disclosure of their FOIA releases, the Archive E-FOIA Audit did find that some real "E-Stars" exist within the federal government, serving as examples to lagging agencies that technology can be harnessed to create state-of-the art FOIA platforms. Unfortunately, our audit also found "E-Delinquents" whose abysmal web performance recalls the teletype era.

E-Delinquents include the Office of Science and Technology Policy at the White House, which, despite being mandated to advise the President on technology policy, does not embrace 21st century practices by posting any frequently requested records online. Another E-Delinquent, the Drug Enforcement Administration, insults its website's viewers by claiming that it "does not maintain records appropriate for FOIA Library at this time."

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.

In the absence of real reform, people and institutions at home and abroad are taking matters into their own hands. In America, the NSA’s overreach is changing the way we communicate with and relate to each other. In order to evade government surveillance, more and more Americans are employing encryption technology.  The veritable explosion of new secure messaging apps like Surespot, OpenWhisper’s collaboration with WhatsApp, the development and deployment of open source anti-surveillance tools like Detekt, the creation of organizationally-sponsored “surveillance self-defense” guides, the push to universalize the https protocol, anti-surveillance book events featuring free encryption workshops— are manifestations of the rise of the personal encryption and pro-privacy digital resistance movement. Its political implications are clear: Americans, along with people around the world, increasingly see the United States government’s overreaching surveillance activities as a threat to be blocked.

The federal government’s vacuum-cleaner approach to surveillance—manifested in Title II of the PATRIOT Act, the FISA Amendments Act, and EO 12333—has backfired in these respects, and the emergence of this digital resistance movement is one result. Indeed, the existence and proliferation of social networks hold the potential to help this movement spread faster and to more of the general public than would have been possible in decades past. This is evidenced by the growing concern worldwide about governments’ ability to access reams of information about people’s lives with relative ease. As one measure, compared to a year ago, 41% of online users in North America now avoid certain Internet sites and applications, 16% change who they communicate with, and 24% censor what they say online. Those numbers, if anywhere close to accurate, are a major concern for democratic society.

Even if commercially available privacy technology proves capable of providing a genuine shield against warrantless or otherwise illegal surveillance by the United States government, it will remain a treatment for the symptom, not a cure for the underlying legal and constitutional malady. In April 2014, a Harris poll of US adults showed that in response to the Snowden revelations, “Almost half of respondents (47%) said that they have changed their online behavior and think more carefully about where they go, what they say, and what they do online.” Set aside for a moment that just the federal government’s collection of the data of innocent Americans is itself likely a violation of the Fourth Amendment. The Harris poll is just one of numerous studies highlighting the collateral damage to American society and politics from NSA’s excesses: segments of our population are now fearful of even associating with individuals or organizations executive branch officials deem controversial or suspicious. Nearly half of Americans say they have changed their online behavior out of a fear of what the federal government might do with their personal information. The Constitution’s free association guarantee has been damaged by the Surveillance State’s very operation.
