Man, at some point Congress is going to have to declare the FBI legally contemptuous and throw them in jail. They continue to refuse to cooperate with DOJ’s Inspector General, as they have been for basically 5 years. But in Michael Horowitz’ latest complaint to Congress, he adds a new spin: FBI is not only obstructing his investigation of the FBI’s management impaired surveillance, now FBI is obstructing his investigation of DEA’s management impaired surveillance. I first reported on DOJ IG’s investigation into DEA’s dragnet databases last April. At that point, the only dragnet we knew about was Hemisphere, which DEA uses to obtain years of phone records as well as location data and other details, before it them parallel constructs that data out of a defendant’s reach.

But since then, we’ve learned of what the government claims to be another database — that used to identify Shantia Hassanshahi in an Iranian sanctions case. After some delay, the government revealed that this was another dragnet, including just international calls. It claims that this database was suspended in September 2013 (around the time Hemisphere became public) and that it is no longer obtaining bulk records for it. According to the latest installment of Michael Horowitz’ complaints about FBI obstruction, he tried to obtain records on the DEA databases on November 20, 2014 (of note, during the period when the government was still refusing to tell even Judge Rudolph Contreras what the database implicating Hassanshahi was). FBI slow-walked production, but promised to provide everything to Horowitz by February 13, 2015. FBI has decided it has to keep reviewing the emails in question to see if there is grand jury, Title III electronic surveillance, and Fair Credit Reporting Act materials, which are the same categories of stuff FBI has refused in the past. So Horowitz is pointing to the language tied to DOJ’s appropriations for FY 2015 which (basically) defunded FBI obstruction. Only FBI continues to obstruct.

There’s one more question about this. As noted, this investigation is supposed to be about DEA’s databases. We’ve already seen that FBI uses Hemisphere (when I asked FBI for comment in advance of this February 4, 2014 article on FBI obstinance, Hemisphere was the one thing they refused all comment on). And obviously, FBI access another DEA database to go after Hassanshahi. So that may be the only reason why Horowitz needs the FBI’s cooperation to investigate the DEA’s dragnets. Plus, assuming FBI is parallel constructing these dragnets just like DEA is, I can understand why they’d want to withhold grand jury information, which would make that clear. Still, I can’t help but wonder — as I have in the past — whether these dragnets are all connected, a constantly moving shell game. That might explain why FBI is so intent on obstructing Horowitz again.

Then we put the data up, but the problem with Solr was it didn’t have a user interface, so we used Project Blacklight, which is open source software normally used by librarians. We used it for the journalists. It’s simple because it allows you to do faceted search—so, for example, you can facet by the folder structure of the leak, by years, by type of file. There were more complex things—it supports queries in regular expressions, so the more advanced users were able to search for documents with a certain pattern of numbers that, for example, passports use. You could also preview and download the documents. ICIJ open-sourced the code of our document processing chain, created by our web developer Matthew Caruana Galizia. We also developed a batch-searching feature. So say you were looking for politicians in your country—you just run it through the system, and you upload your list to Blacklight and you would get a CSV back saying yes, there are matches for these names—not only exact matches, but also matches based on proximity. So you would say “I want Mar Cabra proximity 2” and that would give you “Mar Cabra,” “Mar whatever Cabra,” “Cabra, Mar,”—so that was good, because very quickly journalists were able to see… I have this list of politicians and they are in the data!

Last Sunday, April 3, the first stories emerging from the leaked dataset known as the Panama Papers were published by a global partnership of news organizations working in coordination with the International Consortium of Investigative Journalists, or ICIJ. As we begin the second week of reporting on the leak, Iceland’s Prime Minister has been forced to resign, Germany has announced plans to end anonymous corporate ownership, governments around the world launched investigations into wealthy citizens’ participation in tax havens, the Russian government announced that the investigation was an anti-Putin propaganda operation, and the Chinese government banned mentions of the leak in Chinese media. As the ICIJ-led consortium prepares for its second major wave of reporting on the Panama Papers, we spoke with Mar Cabra, editor of ICIJ’s Data & Research unit and lead coordinator of the data analysis and infrastructure work behind the leak. In our conversation, Cabra reveals ICIJ’s years-long effort to build a series of secure communication and analysis platforms in support of genuinely global investigative reporting collaborations.

For communication, we have the Global I-Hub, which is a platform based on open source software called Oxwall. Oxwall is a social network, like Facebook, which has a wall when you log in with the latest in your network—it has forum topics, links, you can share files, and you can chat with people in real time.

Disaster stories involving the Internet of Things are all the rage. They feature cars (both driven and driverless), the power grid, dams, and tunnel ventilation systems. A particularly vivid and realistic one, near-future fiction published last month in New York Magazine, described a cyberattack on New York that involved hacking of cars, the water system, hospitals, elevators, and the power grid. In these stories, thousands of people die. Chaos ensues. While some of these scenarios overhype the mass destruction, the individual risks are all real. And traditional computer and network security isn’t prepared to deal with them.Classic information security is a triad: confidentiality, integrity, and availability. You’ll see it called “CIA,” which admittedly is confusing in the context of national security. But basically, the three things I can do with your data are steal it (confidentiality), modify it (integrity), or prevent you from getting it (availability).

So far, internet threats have largely been about confidentiality. These can be expensive; one survey estimated that data breaches cost an average of $3.8 million each. They can be embarrassing, as in the theft of celebrity photos from Apple’s iCloud in 2014 or the Ashley Madison breach in 2015. They can be damaging, as when the government of North Korea stole tens of thousands of internal documents from Sony or when hackers stole data about 83 million customer accounts from JPMorgan Chase, both in 2014. They can even affect national security, as in the case of the Office of Personnel Management data breach by—presumptively—China in 2015. On the Internet of Things, integrity and availability threats are much worse than confidentiality threats. It’s one thing if your smart door lock can be eavesdropped upon to know who is home. It’s another thing entirely if it can be hacked to allow a burglar to open the door—or prevent you from opening your door. A hacker who can deny you control of your car, or take over control, is much more dangerous than one who can eavesdrop on your conversations or track your car’s location. With the advent of the Internet of Things and cyber-physical systems in general, we've given the internet hands and feet: the ability to directly affect the physical world. What used to be attacks against data and information have become attacks against flesh, steel, and concrete. Today’s threats include hackers crashing airplanes by hacking into computer networks, and remotely disabling cars, either when they’re turned off and parked or while they’re speeding down the highway. We’re worried about manipulated counts from electronic voting machines, frozen water pipes through hacked thermostats, and remote murder through hacked medical devices. The possibilities are pretty literally endless. The Internet of Things will allow for attacks we can’t even imagine.

By James Bamford Last summer, cyber investigators plowing through the thousands of leaked emails from the Democratic National Committee uncovered a clue.A user named “Феликс Эдмундович” modified one of the documents using settings in the Russian language. Translated, his name was Felix Edmundovich, a pseudonym referring to Felix Edmundovich Dzerzhinsky, the chief of the Soviet Union’s first secret-police organization, the Cheka.It was one more link in the chain of evidence pointing to Russian President Vladimir Putin as the man ultimately behind the operation.During the Cold War, when Soviet intelligence was headquartered in Dzerzhinsky Square in Moscow, Putin was a KGB officer assigned to the First Chief Directorate. Its responsibilities included “active measures,” a form of political warfare that included media manipulation, propaganda and disinformation. Soviet active measures, retired KGB Major General Oleg Kalugin told Army historian Thomas Boghart, aimed to discredit the United States and “conquer world public opinion.”As the Cold War has turned into the code war, Putin recently unveiled his new, greatly enlarged spy organization: the Ministry of State Security, taking the name from Joseph Stalin’s secret service. Putin also resurrected, according to James Clapper, the U.S. director of national intelligence, some of the KGB’s old active- measures tactics. On October 7, Clapper issued a statement: “The U.S. Intelligence community is confident that the Russian government directed the recent compromises of emails from U.S. persons and institutions, including from U.S. political organizations.” Notably, however, the FBI declined to join the chorus, according to reports by the New York Times and CNBC.A week later, Vice President Joe Biden said on NBC’s Meet the Press that "we're sending a message" to Putin and "it will be at the time of our choosing, and under the circumstances that will have the greatest impact." When asked if the American public would know a message was sent, Biden replied, "Hope not." Meanwhile, the CIA was asked, according to an NBC report on October 14, “to deliver options to the White House for a wide-ranging ‘clandestine’ cyber operation designed to harass and ‘embarrass’ the Kremlin leadership.”But as both sides begin arming their cyberweapons, it is critical for the public to be confident that the evidence is really there, and to understand the potential consequences of a tit-for-tat cyberwar escalating into a real war. 

This is a prospect that has long worried Richard Clarke, the former White House cyber czar under President George W. Bush. “It’s highly likely that any war that began as a cyberwar,” Clarke told me last year, “would ultimately end up being a conventional war, where the United States was engaged with bombers and missiles.”The problem with attempting to draw a straight line from the Kremlin to the Clinton campaign is the number of variables that get in the way. For one, there is little doubt about Russian cyber fingerprints in various U.S. campaign activities. Moscow, like Washington, has long spied on such matters. The United States, for example, inserted malware in the recent Mexican election campaign. The question isn’t whether Russia spied on the U.S. presidential election, it’s whether it released the election emails.Then there’s the role of Guccifer 2.0, the person or persons supplying WikiLeaks and other organizations with many of the pilfered emails. Is this a Russian agent? A free agent? A cybercriminal? A combination, or some other entity? No one knows.There is also the problem of groupthink that led to the war in Iraq. For example, just as the National Security Agency, the Central Intelligence Agency and the rest of the intelligence establishment are convinced Putin is behind the attacks, they also believed it was a slam-dunk that Saddam Hussein had a trove of weapons of mass destruction. Consider as well the speed of the political-hacking investigation, followed by a lack of skepticism, culminating in a rush to judgment. After the Democratic committee discovered the potential hack last spring, it called in the cybersecurity firm CrowdStrike in May to analyze the problem.

CrowdStrike took just a month or so before it conclusively determined that Russia’s FSB, the successor to the KGB, and the Russian military intelligence organization, GRU, were behind it. Most of the other major cybersecurity firms quickly fell in line and agreed. By October, the intelligence community made it unanimous. That speed and certainty contrasts sharply with a previous suspected Russian hack in 2010, when the target was the Nasdaq stock market. According to an extensive investigation by Bloomberg Businessweek in 2014, the NSA and FBI made numerous mistakes over many months that stretched to nearly a year. “After months of work,” the article said, “there were still basic disagreements in different parts of government over who was behind the incident and why.”  There was no consensus­, with just a 70 percent certainty that the hack was a cybercrime. Months later, this determination was revised again: It was just a Russian attempt to spy on the exchange in order to design its own. The federal agents also considered the possibility that the Nasdaq snooping was not connected to the Kremlin. Instead, “someone in the FSB could have been running a for-profit operation on the side, or perhaps sold the malware to a criminal hacking group.” Again, that’s why it’s necessary to better understand the role of Guccifer 2.0 in releasing the Democratic National Committee and Clinton campaign emails before launching any cyberweapons.

Brian Krebs is a popular reporter on the cybersecurity beat. He regularly exposes cybercriminals and their tactics, and consequently is regularly a target of their ire. Last month, he wrote about an online attack-for-hire service that resulted in the arrest of the two proprietors. In the aftermath, his site was taken down by a massive DDoS attack.In many ways, this is nothing new. Distributed denial-of-service attacks are a family of attacks that cause websites and other internet-connected systems to crash by overloading them with traffic. The "distributed" part means that other insecure computers on the internet—sometimes in the millions—are recruited to a botnet to unwittingly participate in the attack. The tactics are decades old; DDoS attacks are perpetrated by lone hackers trying to be annoying, criminals trying to extort money, and governments testing their tactics. There are defenses, and there are companies that offer DDoS mitigation services for hire. Basically, it's a size vs. size game. If the attackers can cobble together a fire hose of data bigger than the defender's capability to cope with, they win. If the defenders can increase their capability in the face of attack, they win. What was new about the Krebs attack was both the massive scale and the particular devices the attackers recruited. Instead of using traditional computers for their botnet, they used CCTV cameras, digital video recorders, home routers, and other embedded computers attached to the internet as part of the Internet of Things. Much has been written about how the IoT is wildly insecure. In fact, the software used to attack Krebs was simple and amateurish. What this attack demonstrates is that the economics of the IoT mean that it will remain insecure unless government steps in to fix the problem. This is a market failure that can't get fixed on its own.

The ECJ has ruled that governments cannot force telecom firms to keep all customer data. The ruling, which says the laws violate basic privacy rights, comes as governments call for greater powers for spy agencies.

The Court of Justice of the European Union (ECJ) ruled on Wednesday that laws allowing for the blanket collection and retention of location and traffic data are in breach of EU law. In their decision, the justices wrote that storing such data, which includes text message senders and recipients and call histories, allows for "very precise conclusions to be drawn concerning the private lives of the persons whose data has been retained." "Such national legislation exceeds the limits of what is strictly necessary and cannot be considered to be justified within a democratic society," the Luxembourg-based court said. EU member states seeking to fight a "serious crime" are allowed to retain data in a targeted manner but must be subject to prior review by a court or independent body, the EU's top court said. Exceptions can be made in urgent cases. The decision came amidst growing calls from EU governments for security agencies to be given greater powers with the goal of preventing or investigating attacks. Privacy advocates, on the other hand, said mass data retention is ineffective in combating such crimes.

The court's decision was a response to challenges against data retention laws in Britain and Sweden on the ground that they were no longer valid after the court previously struck down an EU-wide data retention law in 2014. In Sweden, the law requires telecommunications companies to retain all their customers' traffic and location data, without exception, the ECJ said. British law allows authorities to ask firms to keep all communication data for a maximum 12-month period. In the UK, politicians filed a legal challenge against a surveillance law which passed in 2014, part of which was suspended by a British court. British lawmakers then passed the Investigatory Powers Act - the so-called "snooper's charter." A German data retention law, which came into effect at the end of 2015, requires telecommunications companies to store telephone and internet use for 10 weeks, after which point the data must be deleted. The German law also stipulates a shorter storage time of four weeks for location data which results from mobile phone calls. It remains to be seen what effect the ECJ ruling will have on Germany's blanket data retention measures.

The Senate Judiciary Committee held an open hearing today on the FISA Amendments Act, the law that ostensibly authorizes the digital surveillance of hundreds of millions of people both in the United States and around the world. Section 702 of the law, scheduled to expire next year, is designed to allow U.S. intelligence services to collect signals intelligence on foreign targets related to our national security interests. However—thanks to the leaks of many whistleblowers including Edward Snowden, the work of investigative journalists, and statements by public officials—we now know that the FISA Amendments Act has been used to sweep up data on hundreds of millions of people who have no connection to a terrorist investigation, including countless Americans. What do we mean by “countless”? As became increasingly clear in the hearing today, the exact number of Americans impacted by this surveillance is unknown. Senator Franken asked the panel of witnesses, “Is it possible for the government to provide an exact count of how many United States persons have been swept up in Section 702 surveillance? And if not the exact count, then what about an estimate?”

The lack of information makes rigorous oversight of the programs all but impossible. As Senator Franken put it in the hearing today, “When the public lacks even a rough sense of the scope of the government’s surveillance program, they have no way of knowing if the government is striking the right balance, whether we are safeguarding our national security without trampling on our citizens’ fundamental privacy rights. But the public can’t know if we succeed in striking that balance if they don’t even have the most basic information about our major surveillance programs."  Senator Patrick Leahy also questioned the panel about the “minimization procedures” associated with this type of surveillance, the privacy safeguard that is intended to ensure that irrelevant data and data on American citizens is swiftly deleted. Senator Leahy asked the panel: “Do you believe the current minimization procedures ensure that data about innocent Americans is deleted? Is that enough?”  David Medine, who recently announced his pending retirement from the Privacy and Civil Liberties Oversight Board, answered unequivocally:

Elizabeth Goitein, the Brennan Center director whose articulate and thought-provoking testimony was the highlight of the hearing, noted that at this time an exact number would be difficult to provide. However, she asserted that an estimate should be possible for most if not all of the government’s surveillance programs. None of the other panel participants—which included David Medine and Rachel Brand of the Privacy and Civil Liberties Oversight Board as well as Matthew Olsen of IronNet Cybersecurity and attorney Kenneth Wainstein—offered an estimate. Today’s hearing reaffirmed that it is not only the American people who are left in the dark about how many people or accounts are impacted by the NSA’s dragnet surveillance of the Internet. Even vital oversight committees in Congress like the Senate Judiciary Committee are left to speculate about just how far-reaching this surveillance is. It's part of the reason why we urged the House Judiciary Committee to demand that the Intelligence Community provide the public with a number. 

In our society, the rule of law sets limits on what government can and cannot do, no matter how important its goals. To give a simple example, even when chasing a fleeing murder suspect, the police have a duty not to endanger bystanders. The government should pay the same care to our safety in pursuing threats online, but right now we don’t have clear, enforceable rules for government activities like hacking and "digital sabotage." And this is no abstract question—these actions increasingly endanger everyone’s security

The problem became especially clear this year during the San Bernardino case, involving the FBI’s demand that Apple rewrite its iOS operating system to defeat security features on a locked iPhone. Ultimately the FBI exploited an existing vulnerability in iOS and accessed the contents of the phone with the help of an "outside party." Then, with no public process or discussion of the tradeoffs involved, the government refused to tell Apple about the flaw. Despite the obvious fact that the security of the computers and networks we all use is both collective and interwoven—other iPhones used by millions of innocent people presumably have the same vulnerability—the government chose to withhold information Apple could have used to improve the security of its phones. Other examples include intelligence activities like Stuxnet and Bullrun, and law enforcement investigations like the FBI’s mass use of malware against Tor users engaged in criminal behavior. These activities are often disproportionate to stopping legitimate threats, resulting in unpatched software for millions of innocent users, overbroad surveillance, and other collateral effects.  That’s why we’re working on a positive agenda to confront governmental threats to digital security. Put more directly, we’re calling on lawyers, advocates, technologists, and the public to demand a public discussion of whether, when, and how governments can be empowered to break into our computers, phones, and other devices; sabotage and subvert basic security protocols; and stockpile and exploit software flaws and vulnerabilities.  

Smart people in academia and elsewhere have been thinking and writing about these issues for years. But it’s time to take the next step and make clear, public rules that carry the force of law to ensure that the government weighs the tradeoffs and reaches the right decisions. This long post outlines some of the things that can be done. It frames the issue, then describes some of the key areas where EFF is already pursuing this agenda—in particular formalizing the rules for disclosing vulnerabilities and setting out narrow limits for the use of government malware. Finally it lays out where we think the debate should go from here.   

Nearly three years after NSA whistleblower Edward Snowden gave journalists his trove of documents on the intelligence community’s broad and powerful surveillance regime, the public is still missing some crucial, basic facts about how the operations work. Surveillance researchers and privacy advocates published a report on Wednesday outlining what we do know, thanks to the period of discovery post-Snowden — and the overwhelming amount of things we don’t. The NSA’s domestic surveillance was understandably the initial focus of public debate. But that debate never really moved on to examine the NSA’s vastly bigger foreign operations. “There has been relatively little public or congressional debate within the United States about the NSA’s overseas surveillance operations,” write Faiza Patel and Elizabeth Goitein, co-directors of the Brennan Center for Justice’s Liberty and National Security Program, and Amos Toh, legal adviser for David Kaye, the U.N. special rapporteur on the right to freedom of opinion and expression.

The central guidelines the NSA is supposed to follow while spying abroad are described in Executive Order 12333, issued by President Ronald Reagan in 1981, which the authors describe as “a black box.” Just Security, a national security law blog, and the Brennan Center for Justice are co-hosting a panel on Thursday on Capitol Hill to discuss the policy, where the NSA’s privacy and civil liberties officer, Rebecca Richards, will be present. And the independent government watchdog, the Privacy and Civil Liberties Oversight Board, which has authored in-depth reports on other NSA programs, intends to publish a report on 12333 surveillance programs “this year,” according to spokesperson Jen Burita. In the meantime, the authors of the report came up with a list of questions they say need to be answered to create an informed public debate.

There continues to be huge interest from consumers and communities in faster broadband. That’s why we want to bring more people access to Google Fiber — Internet that’s up to 100 times faster than basic broadband. We’ve started early discussions with 34 cities in 9 metro areas around the United States to explore what it would take to bring a new fiber-optic network to their community.

Google is considering deploying Wi-Fi networks in towns and cities covered by its Google Fiber high-speed Internet service. The disclosure is made in a document Google is circulating to 34 cities that are the next candidates to receive Google Fiber in 2015.

Google Fiber is already available in Provo, Utah, and Kansas City, and is promised soon in Austin, Texas. It delivers a "basic speed" service for no charge, a gigabit-per-second service for US$70 per month and a $120 package that includes a bundle of more than 200 TV channels. Installation costs between nothing and $300. Google has sent the 34 cities that are next in line for Google Fiber a detailed request for information and they have until May 1 to reply.

Specific details of the Wi-Fi plan are not included in the document, which was seen by IDG News Service, but Google says it will be "discussing our Wi-Fi plans and related requirements with your city as we move forward with your city during this planning process."

WASHINGTON (AP) -- The Obama administration has been quietly advising local police not to disclose details about surveillance technology they are using to sweep up basic cellphone data from entire neighborhoods, The Associated Press has learned. Citing security reasons, the U.S. has intervened in routine state public records cases and criminal trials regarding use of the technology. This has resulted in police departments withholding materials or heavily censoring documents in rare instances when they disclose any about the purchase and use of such powerful surveillance equipment. Federal involvement in local open records proceedings is unusual. It comes at a time when President Barack Obama has said he welcomes a debate on government surveillance and called for more transparency about spying in the wake of disclosures about classified federal surveillance programs.

One well-known type of this surveillance equipment is known as a Stingray, an innovative way for law enforcement to track cellphones used by suspects and gather evidence. The equipment tricks cellphones into identifying some of their owners' account information, like a unique subscriber number, and transmitting data to police as if it were a phone company's tower. That allows police to obtain cellphone information without having to ask for help from service providers, such as Verizon or AT&T, and can locate a phone without the user even making a call or sending a text message. But without more details about how the technology works and under what circumstances it's used, it's unclear whether the technology might violate a person's constitutional rights or whether it's a good investment of taxpayer dollars. Interviews, court records and public-records requests show the Obama administration is asking agencies to withhold common information about the equipment, such as how the technology is used and how to turn it on. That pushback has come in the form of FBI affidavits and consultation in local criminal cases.

"These extreme secrecy efforts are in relation to very controversial, local government surveillance practices using highly invasive technology," said Nathan Freed Wessler, a staff attorney with the American Civil Liberties Union, which has fought for the release of these types of records. "If public participation means anything, people should have the facts about what the government is doing to them." Harris Corp., a key manufacturer of this equipment, built a secrecy element into its authorization agreement with the Federal Communications Commission in 2011. That authorization has an unusual requirement: that local law enforcement "coordinate with the FBI the acquisition and use of the equipment." Companies like Harris need FCC authorization in order to sell wireless equipment that could interfere with radio frequencies. A spokesman from Harris Corp. said the company will not discuss its products for the Defense Department and law enforcement agencies, although public filings showed government sales of communications systems such as the Stingray accounted for nearly one-third of its $5 billion in revenue. "As a government contractor, our solutions are regulated and their use is restricted," spokesman Jim Burke said.

The Electronic Frontier Foundation (EFF) has urged a federal court to block a U.S. search warrant ordering Microsoft to turn over a customer's emails held in an overseas server, arguing that the case has dangerous privacy implications for Internet users everywhere. The case started in December of last year, when a magistrate judge in New York signed a search warrant seeking records and emails from a Microsoft account in connection with a criminal investigation. However, Microsoft determined that the emails the government sought were on a Microsoft server in Dublin, Ireland. Because a U.S. judge has no authority to issue warrants to search and seize property or data abroad, Microsoft refused to turn over the emails and asked the magistrate to quash the warrant. But the magistrate denied Microsoft's request, ruling there was no foreign search because the data would be reviewed by law enforcement agents in the U.S.

Microsoft appealed the decision. In an amicus brief in support of Microsoft, EFF argues the magistrate's rationale ignores the fact that copying the emails is a "seizure" that takes place in Ireland. "The Fourth Amendment protects from unreasonable search and seizure. You can't ignore the 'seizure' part just because the property is digital and not physical," said EFF Staff Attorney Hanni Fakhoury. "Ignoring this basic point has dangerous implications – it could open the door to unfounded law enforcement access to and collection of data stored around the world."

Third in a series. Part 1 here; Part 2 here. When it comes to the National Security Agency’s recently disclosed use of automated speech recognition technology to search, index and transcribe voice communications, people in the United States may well be asking: But are they transcribing my phone calls? The answer is maybe. A clear-cut answer is elusive because documents in the Snowden archive describe the capability to turn speech into text, but not the extent of its use — and the U.S. intelligence community refuses to answer even the most basic questions on the topic.

thanks to previous explorations of the Snowden archive and some documents released by the Obama administration, we know there are four major methods the NSA uses to get access to phone calls involving Americans — and only one of them technically precludes the use of speech recognition.
