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):

Does the National Security Agency (NSA) have the authority to collect and keep all encrypted Internet traffic for as long as is necessary to decrypt that traffic? That was a question first raised in June 2013, after the minimization procedures governing telephone and Internet records collected under Section 702 of the Foreign Intelligence Surveillance Act were disclosed by Edward Snowden. The issue quickly receded into the background, however, as the world struggled to keep up with the deluge of surveillance disclosures. The Intelligence Authorization Act of 2015, which passed Congress this last December, should bring the question back to the fore. It established retention guidelines for communications collected under Executive Order 12333 and included an exception that allows NSA to keep ‘incidentally’ collected encrypted communications for an indefinite period of time. This creates a massive loophole in the guidelines. NSA’s retention of encrypted communications deserves further consideration today, now that these retention guidelines have been written into law. It has become increasingly clear over the last year that surveillance reform will be driven by technological change—specifically by the growing use of encryption technologies. Therefore, any legislation touching on encryption should receive close scrutiny.

Section 309 of the intel authorization bill describes “procedures for the retention of incidentally acquired communications.” It establishes retention guidelines for surveillance programs that are “reasonably anticipated to result in the acquisition of [telephone or electronic communications] to or from a United States person.” Communications to or from a United States person are ‘incidentally’ collected because the U.S. person is not the actual target of the collection. Section 309 states that these incidentally collected communications must be deleted after five years unless they meet a number of exceptions. One of these exceptions is that “the communication is enciphered or reasonably believed to have a secret meaning.” This exception appears to be directly lifted from NSA’s minimization procedures for data collected under Section 702 of FISA, which were declassified in 2013. 

While Section 309 specifically applies to collection taking place under E.O. 12333, not FISA, several of the exceptions described in Section 309 closely match exceptions in the FISA minimization procedures. That includes the exception for “enciphered” communications. Those minimization procedures almost certainly served as a model for these retention guidelines and will likely shape how this new language is interpreted by the Executive Branch. Section 309 also asks the heads of each relevant member of the intelligence community to develop procedures to ensure compliance with new retention requirements. I expect those procedures to look a lot like the FISA minimization guidelines.

A district court in California has issued a ruling in favor of the National Security Agency in a long-running case over the spy agency’s collection of Internet records.The challenge against the controversial Upstream program was tossed out because additional defense from the government would have required “impermissible disclosure of state secret information,” Judge Jeffrey White wrote in his decision.ADVERTISEMENTUnder the program — details of which were revealed through leaks from Edward Snowden and others — the NSA taps into the fiber cables that make up the backbone of the Internet and gathers information about people's online and phone communications. The agency then filters out communications of U.S. citizens, whose data is protected with legal defenses not extended to foreigners, and searches for “selectors” tied to a terrorist or other target.In 2008, the Electronic Frontier Foundation (EFF) sued the government over the program on behalf of five AT&T customers, who said that the collection violated the constitutional protections to privacy and free speech.

But “substantial details” about the program still remain classified, White, an appointee under former President George W. Bush, wrote in his decision. Moving forward with the merits of a trial would risk “exceptionally grave damage to national security,” he added. <A HREF="http://ws-na.amazon-adsystem.com/widgets/q?rt=tf_mfw&ServiceVersion=20070822&MarketPlace=US&ID=V20070822%2FUS%2Fthehill07-20%2F8001%2Fdffbe72d-f425-4b83-b07e-357ae9d405f6&Operation=NoScript">Amazon.com Widgets</A> The government has been “persuasive” in using its state secrets privilege, he continued, which allows it to withhold evidence from a case that could severely jeopardize national security.   In addition to saying that the program appeared constitutional, the judge also found that the AT&T customers did not even have the standing to sue the NSA over its data gathering.While they may be AT&T customers, White wrote that the evidence presented to the court was “insufficient to establish that the Upstream collection process operates in the manner” that they say it does, which makes it impossible to tell if their information was indeed collected in the NSA program.  The decision is a stinging rebuke to critics of the NSA, who have seen public interest in their cause slowly fade in the months since Snowden’s revelations.

The EFF on Tuesday evening said that it was considering next steps and noted that the court focused on just one program, not the totality of the NSA’s controversial operations.“It would be a travesty of justice if our clients are denied their day in court over the ‘secrecy’ of a program that has been front-page news for nearly a decade,” the group said in a statement.“We will continue to fight to end NSA mass surveillance.”The name of the case is Jewel v. NSA. 

The foundation behind Wikipedia is suing the U.S. government over spying that it says violates core provisions of the Constitution.The Wikimedia Foundation joined forces on Tuesday with a slew of human rights groups, The Nation magazine and other organizations in a lawsuit accusing the National Security Agency (NSA) and Justice Department of violating the constitutional protections for freedom of speech and privacy.

If successful, the lawsuit could land a crippling blow to the web of secretive spying powers wielded by the NSA and exposed by Edward Snowden nearly two years ago. Despite initial outrage after Snowden’s leaks, Congress has yet to make any serious reforms to the NSA, and many of the programs continue largely unchanged.The lawsuit targets the NSA’s “upstream” surveillance program, which taps into the fiber cables that make up the backbone of the global Internet and allows the agency to collect vast amounts of information about people on the Web.“As a result, whenever someone overseas views or edits a Wikipedia page, it’s likely that the N.S.A. is tracking that activity — including the content of what was read or typed, as well as other information that can be linked to the person’s physical location and possible identity,” Tretikov and Wikipedia founder Jimmy Wales wrote in a joint New York Times op-ed announcing the lawsuit. Because the operations are largely overseen solely by the secretive Foreign Intelligence Surveillance Court — which operates out of the public eye and has been accused of acting as a rubber stamp for intelligence agencies — the foundation accused the NSA of violating the guarantees of a fair legal system.In addition to the Wikimedia Foundation and The Nation, the other groups joining the lawsuit are the National Association of Criminal Defense Lawyers, Human Rights Watch, Amnesty International, the Pen American Center, the Global Fund for Women, the Rutherford Institute and the Washington Office on Latin America. The groups are being represented by the American Civil Liberties Union.

In 2013, a lawsuit against similar surveillance powers brought by Amnesty International was tossed out by the Supreme Court on the grounds that the organization was not affected by the spying and had no standing to sue. That decision came before Snowden’s leaks later that summer, however, which included a slide featuring Wikipedia’s logo alongside those of Facebook, Yahoo, Google and other top websites. That should be more than enough grounds for a successful suit, the foundation said. In addition to the new suit, there are also a handful of other outstanding legal challenges to the NSA’s bulk collection of Americans’ phone records, a different program that has inspired some of the most heated antipathy. Those suits are all pending in appeals courts around the country.

In a seminal decision updating and consolidating its previous jurisprudence on surveillance, the Grand Chamber of the European Court of Human Rights took a sideways swing at mass surveillance programs last week, reiterating the centrality of “reasonable suspicion” to the authorization process and the need to ensure interception warrants are targeted to an individual or premises. The decision in Zakharov v. Russia — coming on the heels of the European Court of Justice’s strongly-worded condemnation in Schrems of interception systems that provide States with “generalised access” to the content of communications — is another blow to governments across Europe and the United States that continue to argue for the legitimacy and lawfulness of bulk collection programs. It also provoked the ire of the Russian government, prompting an immediate legislative move to give the Russian constitution precedence over Strasbourg judgments. The Grand Chamber’s judgment in Zakharov is especially notable because its subject matter — the Russian SORM system of interception, which includes the installation of equipment on telecommunications networks that subsequently enables the State direct access to the communications transiting through those networks — is similar in many ways to the interception systems currently enjoying public and judicial scrutiny in the United States, France, and the United Kingdom. Zakharov also provides a timely opportunity to compare the differences between UK and Russian law: Namely, Russian law requires prior independent authorization of interception measures, whereas neither the proposed UK law nor the existing legislative framework do.

The decision is lengthy and comprises a useful restatement and harmonization of the Court’s approach to standing (which it calls “victim status”) in surveillance cases, which is markedly different from that taken by the US Supreme Court. (Indeed, Judge Dedov’s separate but concurring opinion notes the contrast with Clapper v. Amnesty International.) It also addresses at length issues of supervision and oversight, as well as the role played by notification in ensuring the effectiveness of remedies. (Marko Milanovic discusses many of these issues here.) For the purpose of the ongoing debate around the legitimacy of bulk surveillance regimes under international human rights law, however, three particular conclusions of the Court are critical.

The Court took issue with legislation permitting the interception of communications for broad national, military, or economic security purposes (as well as for “ecological security” in the Russian case), absent any indication of the particular circumstances under which an individual’s communications may be intercepted. It said that such broadly worded statutes confer an “almost unlimited degree of discretion in determining which events or acts constitute such a threat and whether that threat is serious enough to justify secret surveillance” (para. 248). Such discretion cannot be unbounded. It can be limited through the requirement for prior judicial authorization of interception measures (para. 249). Non-judicial authorities may also be competent to authorize interception, provided they are sufficiently independent from the executive (para. 258). What is important, the Court said, is that the entity authorizing interception must be “capable of verifying the existence of a reasonable suspicion against the person concerned, in particular, whether there are factual indications for suspecting that person of planning, committing or having committed criminal acts or other acts that may give rise to secret surveillance measures, such as, for example, acts endangering national security” (para. 260). This finding clearly constitutes a significant threshold which a number of existing and pending European surveillance laws would not meet. For example, the existence of individualized reasonable suspicion runs contrary to the premise of signals intelligence programs where communications are intercepted in bulk; by definition, those programs collect information without any consideration of individualized suspicion. Yet the Court was clearly articulating the principle with national security-driven surveillance in mind, and with the knowledge that interception of communications in Russia is conducted by Russian intelligence on behalf of law enforcement agencies.

The first (and thus far only) roll-back of post-9/11 surveillance authorities was implemented over the weekend: The National Security Agency shuttered its program for collecting and holding the metadata of Americans’ phone calls under Section 215 of the Patriot Act. While bulk collection under Section 215 has ended, the government can obtain access to this information under the procedures specified in the USA Freedom Act. Indeed, some experts have argued that the Agency likely has access to more metadata because its earlier dragnet didn’t cover cell phones or Internet calling. In addition, the metadata of calls made by an individual in the United States to someone overseas and vice versa can still be collected in bulk — this takes place abroad under Executive Order 12333. No doubt the NSA wishes that this was the end of the surveillance reform story and the Paris attacks initially gave them an opening. John Brennan, the Director of the CIA, implied that the attacks were somehow related to “hand wringing” about spying and Sen. Tom Cotton (R-Ark.) introduced a bill to delay the shut down of the 215 program. Opponents of encryption were quick to say: “I told you so.”

But the facts that have emerged thus far tell a different story. It appears that much of the planning took place IRL (that’s “in real life” for those of you who don’t have teenagers). The attackers, several of whom were on law enforcement’s radar, communicated openly over the Internet. If France ever has a 9/11 Commission-type inquiry, it could well conclude that the Paris attacks were a failure of the intelligence agencies rather than a failure of intelligence authorities. Despite the passage of the USA Freedom Act, US surveillance authorities have remained largely intact. Section 702 of the FISA Amendments Act — which is the basis of programs like PRISM and the NSA’s Upstream collection of information from Internet cables — sunsets in the summer of 2017. While it’s difficult to predict the political environment that far out, meaningful reform of Section 702 faces significant obstacles. Unlike the Section 215 program, which was clearly aimed at Americans, Section 702 is supposedly targeted at foreigners and only picks up information about Americans “incidentally.” The NSA has refused to provide an estimate of how many Americans’ information it collects under Section 702, despite repeated requests from lawmakers and most recently a large cohort of advocates. The Section 215 program was held illegal by two federal courts (here and here), but civil attempts to challenge Section 702 have run into standing barriers. Finally, while two review panels concluded that the Section 215 program provided little counterterrorism benefit (here and here), they found that the Section 702 program had been useful.

There is, nonetheless, some pressure to narrow the reach of Section 702. The recent decision by the European Court of Justice in the safe harbor case suggests that data flows between Europe and the US may be restricted unless the PRISM program is modified to protect the information of Europeans (see here, here, and here for discussion of the decision and reform options). Pressure from Internet companies whose business is suffering — estimates run to the tune of $35 to 180 billion — as a result of disclosures about NSA spying may also nudge lawmakers towards reform. One of the courts currently considering criminal cases which rely on evidence derived from Section 702 surveillance may hold the program unconstitutional either on the basis of the Fourth Amendment or Article III for the reasons set out in this Brennan Center report. A federal district court in Colorado recently rejected such a challenge, although as explained in Steve’s post, the decision did not seriously explore the issues. Further litigation in the European courts too could have an impact on the debate.
