Yesterday, news broke that Google has been stealth downloading audio listeners onto every computer that runs Chrome, and transmits audio data back to Google. Effectively, this means that Google had taken itself the right to listen to every conversation in every room that runs Chrome somewhere, without any kind of consent from the people eavesdropped on. In official statements, Google shrugged off the practice with what amounts to “we can do that”.It looked like just another bug report. "When I start Chromium, it downloads something." Followed by strange status information that notably included the lines "Microphone: Yes" and "Audio Capture Allowed: Yes".

Without consent, Google’s code had downloaded a black box of code that – according to itself – had turned on the microphone and was actively listening to your room.A brief explanation of the Open-source / Free-software philosophy is needed here. When you’re installing a version of GNU/Linux like Debian or Ubuntu onto a fresh computer, thousands of really smart people have analyzed every line of human-readable source code before that operating system was built into computer-executable binary code, to make it common and open knowledge what the machine actually does instead of trusting corporate statements on what it’s supposed to be doing. Therefore, you don’t install black boxes onto a Debian or Ubuntu system; you use software repositories that have gone through this source-code audit-then-build process. Maintainers of operating systems like Debian and Ubuntu use many so-called “upstreams” of source code to build the final product.Chromium, the open-source version of Google Chrome, had abused its position as trusted upstream to insert lines of source code that bypassed this audit-then-build process, and which downloaded and installed a black box of unverifiable executable code directly onto computers, essentially rendering them compromised. We don’t know and can’t know what this black box does. But we see reports that the microphone has been activated, and that Chromium considers audio capture permitted.

This was supposedly to enable the “Ok, Google” behavior – that when you say certain words, a search function is activated. Certainly a useful feature. Certainly something that enables eavesdropping of every conversation in the entire room, too.Obviously, your own computer isn’t the one to analyze the actual search command. Google’s servers do. Which means that your computer had been stealth configured to send what was being said in your room to somebody else, to a private company in another country, without your consent or knowledge, an audio transmission triggered by… an unknown and unverifiable set of conditions.Google had two responses to this. The first was to introduce a practically-undocumented switch to opt out of this behavior, which is not a fix: the default install will still wiretap your room without your consent, unless you opt out, and more importantly, know that you need to opt out, which is nowhere a reasonable requirement. But the second was more of an official statement following technical discussions on Hacker News and other places. That official statement amounted to three parts (paraphrased, of course):

he message arrived at night and consisted of three words: “Good evening sir!” The sender was a hacker who had written a series of provocative memos at the National Security Agency. His secret memos had explained — with an earthy use of slang and emojis that was unusual for an operative of the largest eavesdropping organization in the world — how the NSA breaks into the digital accounts of people who manage computer networks, and how it tries to unmask people who use Tor to browse the web anonymously. Outlining some of the NSA’s most sensitive activities, the memos were leaked by Edward Snowden, and I had written about a few of them for The Intercept. There is no Miss Manners for exchanging pleasantries with a man the government has trained to be the digital equivalent of a Navy SEAL. Though I had initiated the contact, I was wary of how he might respond. The hacker had publicly expressed a visceral dislike for Snowden and had accused The Intercept of jeopardizing lives by publishing classified information. One of his memos outlined the ways the NSA reroutes (or “shapes”) the internet traffic of entire countries, and another memo was titled “I Hunt Sysadmins.” I felt sure he could hack anyone’s computer, including mine. Good evening sir!

I got lucky with the hacker, because he recently left the agency for the cybersecurity industry; it would be his choice to talk, not the NSA’s. Fortunately, speaking out is his second nature.

Ever wonder why most e-mail clients hide images by default? The reason for the "display images" button is because images in an e-mail must be loaded from a third-party server. For promotional e-mails and spam, usually this server is operated by the entity that sent the e-mail. So when you load these images, you aren't just receiving an image—you're also sending a ton of data about yourself to the e-mail marketer. Loading images from these promotional e-mails reveals a lot about you. Marketers get a rough idea of your location via your IP address. They can see the HTTP referrer, meaning the URL of the page that requested the image. With the referral data, marketers can see not only what client you are using (desktop app, Web, mobile, etc.) but also what folder you were viewing the e-mail in. For instance, if you had a Gmail folder named "Ars Technica" and loaded e-mail images, the referral URL would be "https://mail.google.com/mail/u/0/#label/Ars+Technica"—the folder is right there in the URL. The same goes for the inbox, spam, and any other location. It's even possible to uniquely identify each e-mail, so marketers can tell which e-mail address requested the images—they know that you've read the e-mail. And if it was spam, this will often earn you more spam since the spammers can tell you've read their last e-mail.

But Google has just announced a move that will shut most of these tactics down: it will cache all images for Gmail users. Embedded images will now be saved by Google, and the e-mail content will be modified to display those images from Google's cache, instead of from a third-party server. E-mail marketers will no longer be able to get any information from images—they will see a single request from Google, which will then be used to send the image out to all Gmail users. Unless you click on a link, marketers will have no idea the e-mail has been seen. While this means improved privacy from e-mail marketers, Google will now be digging deeper than ever into your e-mails and literally modifying the contents. If you were worried about e-mail scanning, this may take things a step further. However, if you don't like the idea of cached images, you can turn it off in the settings. This move will allow Google to automatically display images, killing the "display all images" button in Gmail. Google servers should also be faster than the usual third-party image host. Hosting all images sent to all Gmail users sounds like a huge bandwidth and storage undertaking, but if anyone can do it, it's Google. The new image handling will rollout to desktop users today, and it should hit mobile apps sometime in early 2014. There's also a bonus side effect for Google: e-mail marketing is advertising. Google exists because of advertising dollars, but they don't do e-mail marketing. They've just made a competitive form of advertising much less appealing and informative to advertisers. No doubt Google hopes this move pushes marketers to spend less on e-mail and more on Adsense.

Edward Snowden has hit out at Dropbox and other services he says are “hostile to privacy,” urging web users to abandon unencrypted communication and adjust privacy settings to prevent governments from spying on them in increasingly intrusive ways. “We are no longer citizens, we no longer have leaders. We’re subjects, and we have rulers,” Snowden told The New Yorker magazine in a comprehensive hour-long interview. There isn’t enough investment into security research, into understanding how metadata could better be protected and why that is more necessary today than yesterday, he said.

There isn’t enough investment into security research, into understanding how metadata could better be protected and why that is more necessary today than yesterday, he said.

The whistleblower believes one fallacy in how authorities view individual rights has to do with making the individual forsake those rights by default. Snowden’s point is that the moment you are compelled to reveal that you have nothing to hide is when the right to privacy stops being a right – because you are effectively waiving that right. “When you say, ‘I have nothing to hide,’ you’re saying, ‘I don’t care about this right.’ You’re saying, ‘I don’t have this right, because I’ve got to the point where I have to justify it.’ The way rights work is, the government has to justify its intrusion into your rights – you don’t have to justify why you need freedom of speech.” In that situation, it becomes OK to live in a world where one is no longer interested in privacy as such – a world where Facebook, Google and Dropbox have become ubiquitous, and where there are virtually no safeguards against the wrongful use of the information one puts there.

When you sign in to Chrome and enable sync, Chrome keeps your information secure by using your Google Account credentials to encrypt your synced passwords. Alternatively, you can choose to encrypt all of your synced data with a sync passphrase. This sync passphrase is stored on your computer and isn't sent to Google.

Click the Chrome menu on the browser toolbar. Select Signed in as <your email address> (you must be signed in to Chrome already). In the "Sign in" section, click Advanced sync settings. Choose an encryption option: Encrypt synced passwords with your Google credentials: This is the default option. Your saved passwords are encrypted on Google's servers and protected with your Google Account credentials. Encrypt all synced data with your own sync passphrase: Select this if you'd like to encrypt all the data you've chosen to sync. You can provide your own passphrase that will only be stored on your computer. Click OK.

Security experts call it a “drive-by download”: a hacker infiltrates a high-traffic website and then subverts it to deliver malware to every single visitor. It’s one of the most powerful tools in the black hat arsenal, capable of delivering thousands of fresh victims into a hackers’ clutches within minutes. Now the technique is being adopted by a different kind of a hacker—the kind with a badge. For the last two years, the FBI has been quietly experimenting with drive-by hacks as a solution to one of law enforcement’s knottiest Internet problems: how to identify and prosecute users of criminal websites hiding behind the powerful Tor anonymity system. The approach has borne fruit—over a dozen alleged users of Tor-based child porn sites are now headed for trial as a result. But it’s also engendering controversy, with charges that the Justice Department has glossed over the bulk-hacking technique when describing it to judges, while concealing its use from defendants. Critics also worry about mission creep, the weakening of a technology relied on by human rights workers and activists, and the potential for innocent parties to wind up infected with government malware because they visited the wrong website. “This is such a big leap, there should have been congressional hearings about this,” says ACLU technologist Chris Soghoian, an expert on law enforcement’s use of hacking tools. “If Congress decides this is a technique that’s perfectly appropriate, maybe that’s OK. But let’s have an informed debate about it.”

The FBI’s use of malware is not new. The bureau calls the method an NIT, for “network investigative technique,” and the FBI has been using it since at least 2002 in cases ranging from computer hacking to bomb threats, child porn to extortion. Depending on the deployment, an NIT can be a bulky full-featured backdoor program that gives the government access to your files, location, web history and webcam for a month at a time, or a slim, fleeting wisp of code that sends the FBI your computer’s name and address, and then evaporates. What’s changed is the way the FBI uses its malware capability, deploying it as a driftnet instead of a fishing line. And the shift is a direct response to Tor, the powerful anonymity system endorsed by Edward Snowden and the State Department alike.

In August 2013, as evidence emerged of the active participation by New Zealand in the “Five Eyes” mass surveillance program exposed by Edward Snowden, the country’s conservative Prime Minister, John Key, vehemently denied that his government engages in such spying. He went beyond mere denials, expressly vowing to resign if it were ever proven that his government engages in mass surveillance of New Zealanders. He issued that denial, and the accompanying resignation vow, in order to reassure the country over fears provoked by a new bill he advocated to increase the surveillance powers of that country’s spying agency, Government Communications Security Bureau (GCSB) — a bill that passed by one vote thanks to the Prime Minister’s guarantees that the new law would not permit mass surveillance.

Since then, a mountain of evidence has been presented that indisputably proves that New Zealand does exactly that which Prime Minister Key vehemently denied — exactly that which he said he would resign if it were proven was done. Last September, we reported on a secret program of mass surveillance at least partially implemented by the Key government that was designed to exploit the very law that Key was publicly insisting did not permit mass surveillance. At the time, Snowden, citing that report as well as his own personal knowledge of GCSB’s participation in the mass surveillance tool XKEYSCORE, wrote in an article for The Intercept: Let me be clear: any statement that mass surveillance is not performed in New Zealand, or that the internet communications are not comprehensively intercepted and monitored, or that this is not intentionally and actively abetted by the GCSB, is categorically false. . . . The prime minister’s claim to the public, that “there is no and there never has been any mass surveillance” is false. The GCSB, whose operations he is responsible for, is directly involved in the untargeted, bulk interception and algorithmic analysis of private communications sent via internet, satellite, radio, and phone networks.

A series of new reports last week by New Zealand journalist Nicky Hager, working with my Intercept colleague Ryan Gallagher, has added substantial proof demonstrating GCSB’s widespread use of mass surveillance. An article last week in The New Zealand Herald demonstrated that “New Zealand’s electronic surveillance agency, the GCSB, has dramatically expanded its spying operations during the years of John Key’s National Government and is automatically funnelling vast amounts of intelligence to the US National Security Agency.” Specifically, its “intelligence base at Waihopai has moved to ‘full-take collection,’ indiscriminately intercepting Asia-Pacific communications and providing them en masse to the NSA through the controversial NSA intelligence system XKeyscore, which is used to monitor emails and internet browsing habits.” Moreover, the documents “reveal that most of the targets are not security threats to New Zealand, as has been suggested by the Government,” but “instead, the GCSB directs its spying against a surprising array of New Zealand’s friends, trading partners and close Pacific neighbours.” A second report late last week published jointly by Hager and The Intercept detailed the role played by GCSB’s Waihopai base in aiding NSA’s mass surveillance activities in the Pacific (as Hager was working with The Intercept on these stories, his house was raided by New Zealand police for 10 hours, ostensibly to find Hager’s source for a story he published that was politically damaging to Key).

Gagging orders in the FBI's National Security Letters are all above board and constitutional, a California court has ruled. These security letters are typically sent to internet giants demanding information on whoever is behind a username or email address. Crucially, these requests include clauses that prevent the organizations from warning specific subscribers that they are under surveillance by the Feds. Cloudflare and Credo Mobile aren't happy with that, and – with the help of rights warriors at the EFF – challenged the gagging orders. Despite earlier successes in their legal battle, the 9th US Circuit Court of Appeals ruled [PDF] on Monday that the gagging orders do not trample on First Amendment rights.

The FBI dishes out thousands of National Security Letters (NSLs) every year; they can simply be issued by a special agent in charge in a bureau field office, and don’t require judicial review. They allow the Feds to obtain the name, address, and records of any services used – but not the contents of conversations – plus billing records of a person, and forbid the hosting company from telling the subject, meaning those under investigation can’t challenge the decision. It used to be the case that companies couldn’t even mention the existence of the NSL system for fear of prosecution. However, in 2013 a US district court in San Francisco ruled that such extreme gagging violated the First Amendment. That decision came after Google, and later others, started publishing the number of NSL orders that had been received, in defiance of the law. In 2015 the Obama administration amended the law to allow companies limited rights to disclose NSL orders, and to set a three-year limit for the gagging order. It also set up a framework for companies to challenge the legitimacy of NSL subpoenas, and it was these changes that caused the appeals court verdict in favor of the government.

These and other classified documents provided by former NSA contractor Edward Snowden reveal that the NSA has developed technology not just to record and transcribe private conversations but to automatically identify the speakers. Americans most regularly encounter this technology, known as speaker recognition, or speaker identification, when they wake up Amazon’s Alexa or call their bank. But a decade before voice commands like “Hello Siri” and “OK Google” became common household phrases, the NSA was using speaker recognition to monitor terrorists, politicians, drug lords, spies, and even agency employees. The technology works by analyzing the physical and behavioral features that make each person’s voice distinctive, such as the pitch, shape of the mouth, and length of the larynx. An algorithm then creates a dynamic computer model of the individual’s vocal characteristics. This is what’s popularly referred to as a “voiceprint.” The entire process — capturing a few spoken words, turning those words into a voiceprint, and comparing that representation to other “voiceprints” already stored in the database — can happen almost instantaneously. Although the NSA is known to rely on finger and face prints to identify targets, voiceprints, according to a 2008 agency document, are “where NSA reigns supreme.” It’s not difficult to see why. By intercepting and recording millions of overseas telephone conversations, video teleconferences, and internet calls — in addition to capturing, with or without warrants, the domestic conversations of Americans — the NSA has built an unrivaled collection of distinct voices. Documents from the Snowden archive reveal that analysts fed some of these recordings to speaker recognition algorithms that could connect individuals to their past utterances, even when they had used unknown phone numbers, secret code words, or multiple languages.

The classified documents, dating from 2004 to 2012, show the NSA refining increasingly sophisticated iterations of its speaker recognition technology. They confirm the uses of speaker recognition in counterterrorism operations and overseas drug busts. And they suggest that the agency planned to deploy the technology not just to retroactively identify spies like Pelton but to prevent whistleblowers like Snowden.
