Senator Leahy, they don’t. The minimization procedures call for the deletion of innocent Americans’ information upon discovery to determine whether it has any foreign intelligence value. But what the board’s report found is that in fact information is never deleted. It sits in the databases for 5 years, or sometimes longer. And so the minimization doesn’t really address the privacy concerns of incidentally collected communications—again, where there’s been no warrant at all in the process… In the United States, we simply can’t read people’s emails and listen to their phone calls without court approval, and the same should be true when the government shifts its attention to Americans under this program. One of the most startling exchanges from the hearing today came toward the end of the session, when Senator Dianne Feinstein—who also sits on the Intelligence Committee—seemed taken aback by Ms. Goitein’s mention of “backdoor searches.” 

Feinstein: Wow, wow. What do you call it? What’s a backdoor search? Goitein: Backdoor search is when the FBI or any other agency targets a U.S. person for a search of data that was collected under Section 702, which is supposed to be targeted against foreigners overseas. Feinstein: Regardless of the minimization that was properly carried out. Goitein: Well the data is searched in its unminimized form. So the FBI gets raw data, the NSA, the CIA get raw data. And they search that raw data using U.S. person identifiers. That’s what I’m referring to as backdoor searches. It’s deeply concerning that any member of Congress, much less a member of the Senate Judiciary Committee and the Senate Intelligence Committee, might not be aware of the problem surrounding backdoor searches. In April 2014, the Director of National Intelligence acknowledged the searches of this data, which Senators Ron Wyden and Mark Udall termed “the ‘back-door search’ loophole in section 702.” The public was so incensed that the House of Representatives passed an amendment to that year's defense appropriations bill effectively banning the warrantless backdoor searches. Nonetheless, in the hearing today it seemed like Senator Feinstein might not recognize or appreciate the serious implications of allowing U.S. law enforcement agencies to query the raw data collected through these Internet surveillance programs. Hopefully today’s testimony helped convince the Senator that there is more to this topic than what she’s hearing in jargon-filled classified security briefings.

This language is broad, circular, and technically incoherent, so it takes some effort to parse appropriately. When the minimization procedures were disclosed in 2013, this language was interpreted by outside commentators to mean that NSA may keep all encrypted data that has been incidentally collected under Section 702 for at least as long as is necessary to decrypt that data. Is this the correct interpretation? I think so. It is important to realize that the language above isn’t just broad. It seems purposefully broad. The part regarding relevance seems to mirror the rationale NSA has used to justify its bulk phone records collection program. Under that program, all phone records were relevant because some of those records could be valuable to terrorism investigations and (allegedly) it isn’t possible to collect only those valuable records. This is the “to find a needle a haystack, you first have to have the haystack” argument. The same argument could be applied to encrypted data and might be at play here.

This exception doesn’t just apply to encrypted data that might be relevant to a current foreign intelligence investigation. It also applies to cases in which the encrypted data is likely to become relevant to a future intelligence requirement. This is some remarkably generous language. It seems one could justify keeping any type of encrypted data under this exception. Upon close reading, it is difficult to avoid the conclusion that these procedures were written carefully to allow NSA to collect and keep a broad category of encrypted data under the rationale that this data might contain the communications of NSA targets and that it might be decrypted in the future. If NSA isn’t doing this today, then whoever wrote these minimization procedures wanted to at least ensure that NSA has the authority to do this tomorrow.

There are a few additional observations that are worth making regarding these nominally new retention guidelines and Section 702 collection. First, the concept of incidental collection as it has typically been used makes very little sense when applied to encrypted data. The way that NSA’s Section 702 upstream “about” collection is understood to work is that technology installed on the network does some sort of pattern match on Internet traffic; say that an NSA target uses example@gmail.com to communicate. NSA would then search content of emails for references to example@gmail.com. This could notionally result in a lot of incidental collection of U.S. persons’ communications whenever the email that references example@gmail.com is somehow mixed together with emails that have nothing to do with the target. This type of incidental collection isn’t possible when the data is encrypted because it won’t be possible to search and find example@gmail.com in the body of an email. Instead, example@gmail.com will have been turned into some alternative, indecipherable string of bits on the network. Incidental collection shouldn’t occur because the pattern match can’t occur in the first place. This demonstrates that, when communications are encrypted, it will be much harder for NSA to search Internet traffic for a unique ID associated with a specific target.

This lends further credence to the conclusion above: rather than doing targeted collection against specific individuals, NSA is collecting, or plans to collect, a broad class of data that is encrypted. For example, NSA might collect all PGP encrypted emails or all Tor traffic. In those cases, NSA could search Internet traffic for patterns associated with specific types of communications, rather than specific individuals’ communications. This would technically meet the definition of incidental collection because such activity would result in the collection of communications of U.S. persons who aren’t the actual targets of surveillance. Collection of all Tor traffic would entail a lot of this “incidental” collection because the communications of NSA targets would be mixed with the communications of a large number of non-target U.S. persons. However, this “incidental” collection is inconsistent with how the term is typically used, which is to refer to over-collection resulting from targeted surveillance programs. If NSA were collecting all Tor traffic, that activity wouldn’t actually be targeted, and so any resulting over-collection wouldn’t actually be incidental. Moreover, greater use of encryption by the general public would result in an ever-growing amount of this type of incidental collection.

This type of collection would also be inconsistent with representations of Section 702 upstream collection that have been made to the public and to Congress. Intelligence officials have repeatedly suggested that search terms used as part of this program have a high degree of specificity. They have also argued that the program is an example of targeted rather than bulk collection. ODNI General Counsel Robert Litt, in a March 2014 meeting before the Privacy and Civil Liberties Oversight Board, stated that “there is either a misconception or a mischaracterization commonly repeated that Section 702 is a form of bulk collection. It is not bulk collection. It is targeted collection based on selectors such as telephone numbers or email addresses where there’s reason to believe that the selector is relevant to a foreign intelligence purpose.” The collection of Internet traffic based on patterns associated with types of communications would be bulk collection; more akin to NSA’s collection of phone records en mass than it is to targeted collection focused on specific individuals. Moreover, this type of collection would certainly fall within the definition of bulk collection provided just last week by the National Academy of Sciences: “collection in which a significant portion of the retained data pertains to identifiers that are not targets at the time of collection.”

The Section 702 minimization procedures, which will serve as a template for any new retention guidelines established for E.O. 12333 collection, create a large loophole for encrypted communications. With everything from email to Internet browsing to real-time communications moving to encrypted formats, an ever-growing amount of Internet traffic will fall within this loophole.

The report also details the ODNI’s and IC’s plans for the future, including: (1) Working with Congress to reauthorize bulk collection under Section 215. (2) Updating agency guidelines under Executive Order 12333 “to protect the privacy and civil liberties of U.S. persons.” (3) Producing another annual report in January 2016 on the IC’s progress in implementing signals intelligence reforms. These plans raise more questions than they answer. Given the considerable doubts about Section 215’s effectiveness, why is the ODNI pushing for its reauthorization? And what will the ODNI consider appropriate privacy protections under Executive Order 12333?

The latest update to the bill tacks on yet another kind of information, anything related to impending “serious economic harm.” All of those vague terms, Greene argues, widen the pipe of data that companies can send the government, expanding CISA into a surveillance system for the intelligence community and domestic law enforcement. If information-sharing legislation does not include adequate privacy protections, then...It’s a surveillance bill by another name. Senator Ron Wyden

“CISA goes far beyond [cybersecurity], and permits law enforcement to use information it receives for investigations and prosecutions of a wide range of crimes involving any level of physical force,” reads the letter from the coalition opposing CISA. “The lack of use limitations creates yet another loophole for law enforcement to conduct backdoor searches on Americans—including searches of digital communications that would otherwise require law enforcement to obtain a warrant based on probable cause. This undermines Fourth Amendment protections and constitutional principles.”

A huge volume of the Internet data GCHQ collects flows directly into a massive repository named Black Hole, which is at the core of the agency’s online spying operations, storing raw logs of intercepted material before it has been subject to analysis. Black Hole contains data collected by GCHQ as part of bulk “unselected” surveillance, meaning it is not focused on particular “selected” targets and instead includes troves of data indiscriminately swept up about ordinary people’s online activities. Between August 2007 and March 2009, GCHQ documents say that Black Hole was used to store more than 1.1 trillion “events” — a term the agency uses to refer to metadata records — with about 10 billion new entries added every day. As of March 2009, the largest slice of data Black Hole held — 41 percent — was about people’s Internet browsing histories. The rest included a combination of email and instant messenger records, details about search engine queries, information about social media activity, logs related to hacking operations, and data on people’s use of tools to browse the Internet anonymously.

Throughout this period, as smartphone sales started to boom, the frequency of people’s Internet use was steadily increasing. In tandem, British spies were working frantically to bolster their spying capabilities, with plans afoot to expand the size of Black Hole and other repositories to handle an avalanche of new data. By 2010, according to the documents, GCHQ was logging 30 billion metadata records per day. By 2012, collection had increased to 50 billion per day, and work was underway to double capacity to 100 billion. The agency was developing “unprecedented” techniques to perform what it called “population-scale” data mining, monitoring all communications across entire countries in an effort to detect patterns or behaviors deemed suspicious. It was creating what it said would be, by 2013, “the world’s biggest” surveillance engine “to run cyber operations and to access better, more valued data for customers to make a real world difference.”

A document from the GCHQ target analysis center (GTAC) shows the Black Hole repository’s structure.

The data is searched by GCHQ analysts in a hunt for behavior online that could be connected to terrorism or other criminal activity. But it has also served a broader and more controversial purpose — helping the agency hack into European companies’ computer networks. In the lead up to its secret mission targeting Netherlands-based Gemalto, the largest SIM card manufacturer in the world, GCHQ used MUTANT BROTH in an effort to identify the company’s employees so it could hack into their computers. The system helped the agency analyze intercepted Facebook cookies it believed were associated with Gemalto staff located at offices in France and Poland. GCHQ later successfully infiltrated Gemalto’s internal networks, stealing encryption keys produced by the company that protect the privacy of cell phone communications.

Similarly, MUTANT BROTH proved integral to GCHQ’s hack of Belgian telecommunications provider Belgacom. The agency entered IP addresses associated with Belgacom into MUTANT BROTH to uncover information about the company’s employees. Cookies associated with the IPs revealed the Google, Yahoo, and LinkedIn accounts of three Belgacom engineers, whose computers were then targeted by the agency and infected with malware. The hacking operation resulted in GCHQ gaining deep access into the most sensitive parts of Belgacom’s internal systems, granting British spies the ability to intercept communications passing through the company’s networks.

In March, a U.K. parliamentary committee published the findings of an 18-month review of GCHQ’s operations and called for an overhaul of the laws that regulate the spying. The committee raised concerns about the agency gathering what it described as “bulk personal datasets” being held about “a wide range of people.” However, it censored the section of the report describing what these “datasets” contained, despite acknowledging that they “may be highly intrusive.” The Snowden documents shine light on some of the core GCHQ bulk data-gathering programs that the committee was likely referring to — pulling back the veil of secrecy that has shielded some of the agency’s most controversial surveillance operations from public scrutiny. KARMA POLICE and MUTANT BROTH are among the key bulk collection systems. But they do not operate in isolation — and the scope of GCHQ’s spying extends far beyond them.

The agency operates a bewildering array of other eavesdropping systems, each serving its own specific purpose and designated a unique code name, such as: SOCIAL ANTHROPOID, which is used to analyze metadata on emails, instant messenger chats, social media connections and conversations, plus “telephony” metadata about phone calls, cell phone locations, text and multimedia messages; MEMORY HOLE, which logs queries entered into search engines and associates each search with an IP address; MARBLED GECKO, which sifts through details about searches people have entered into Google Maps and Google Earth; and INFINITE MONKEYS, which analyzes data about the usage of online bulletin boards and forums. GCHQ has other programs that it uses to analyze the content of intercepted communications, such as the full written body of emails and the audio of phone calls. One of the most important content collection capabilities is TEMPORA, which mines vast amounts of emails, instant messages, voice calls and other communications and makes them accessible through a Google-style search tool named XKEYSCORE.

As of September 2012, TEMPORA was collecting “more than 40 billion pieces of content a day” and it was being used to spy on people across Europe, the Middle East, and North Africa, according to a top-secret memo outlining the scope of the program. The existence of TEMPORA was first revealed by The Guardian in June 2013. To analyze all of the communications it intercepts and to build a profile of the individuals it is monitoring, GCHQ uses a variety of different tools that can pull together all of the relevant information and make it accessible through a single interface. SAMUEL PEPYS is one such tool, built by the British spies to analyze both the content and metadata of emails, browsing sessions, and instant messages as they are being intercepted in real time. One screenshot of SAMUEL PEPYS in action shows the agency using it to monitor an individual in Sweden who visited a page about GCHQ on the U.S.-based anti-secrecy website Cryptome.

Partly due to the U.K.’s geographic location — situated between the United States and the western edge of continental Europe — a large amount of the world’s Internet traffic passes through its territory across international data cables. In 2010, GCHQ noted that what amounted to “25 percent of all Internet traffic” was transiting the U.K. through some 1,600 different cables. The agency said that it could “survey the majority of the 1,600” and “select the most valuable to switch into our processing systems.”

According to Joss Wright, a research fellow at the University of Oxford’s Internet Institute, tapping into the cables allows GCHQ to monitor a large portion of foreign communications. But the cables also transport masses of wholly domestic British emails and online chats, because when anyone in the U.K. sends an email or visits a website, their computer will routinely send and receive data from servers that are located overseas. “I could send a message from my computer here [in England] to my wife’s computer in the next room and on its way it could go through the U.S., France, and other countries,” Wright says. “That’s just the way the Internet is designed.” In other words, Wright adds, that means “a lot” of British data and communications transit across international cables daily, and are liable to be swept into GCHQ’s databases.

A map from a classified GCHQ presentation about intercepting communications from undersea cables. GCHQ is authorized to conduct dragnet surveillance of the international data cables through so-called external warrants that are signed off by a government minister. The external warrants permit the agency to monitor communications in foreign countries as well as British citizens’ international calls and emails — for example, a call from Islamabad to London. They prohibit GCHQ from reading or listening to the content of “internal” U.K. to U.K. emails and phone calls, which are supposed to be filtered out from GCHQ’s systems if they are inadvertently intercepted unless additional authorization is granted to scrutinize them. However, the same rules do not apply to metadata. A little-known loophole in the law allows GCHQ to use external warrants to collect and analyze bulk metadata about the emails, phone calls, and Internet browsing activities of British people, citizens of closely allied countries, and others, regardless of whether the data is derived from domestic U.K. to U.K. communications and browsing sessions or otherwise. In March, the existence of this loophole was quietly acknowledged by the U.K. parliamentary committee’s surveillance review, which stated in a section of its report that “special protection and additional safeguards” did not apply to metadata swept up using external warrants and that domestic British metadata could therefore be lawfully “returned as a result of searches” conducted by GCHQ.

Perhaps unsurprisingly, GCHQ appears to have readily exploited this obscure legal technicality. Secret policy guidance papers issued to the agency’s analysts instruct them that they can sift through huge troves of indiscriminately collected metadata records to spy on anyone regardless of their nationality. The guidance makes clear that there is no exemption or extra privacy protection for British people or citizens from countries that are members of the Five Eyes, a surveillance alliance that the U.K. is part of alongside the U.S., Canada, Australia, and New Zealand. “If you are searching a purely Events only database such as MUTANT BROTH, the issue of location does not occur,” states one internal GCHQ policy document, which is marked with a “last modified” date of July 2012. The document adds that analysts are free to search the databases for British metadata “without further authorization” by inputing a U.K. “selector,” meaning a unique identifier such as a person’s email or IP address, username, or phone number. Authorization is “not needed for individuals in the U.K.,” another GCHQ document explains, because metadata has been judged “less intrusive than communications content.” All the spies are required to do to mine the metadata troves is write a short “justification” or “reason” for each search they conduct and then click a button on their computer screen.

Intelligence GCHQ collects on British persons of interest is shared with domestic security agency MI5, which usually takes the lead on spying operations within the U.K. MI5 conducts its own extensive domestic surveillance as part of a program called DIGINT (digital intelligence).

GCHQ’s documents suggest that it typically retains metadata for periods of between 30 days to six months. It stores the content of communications for a shorter period of time, varying between three to 30 days. The retention periods can be extended if deemed necessary for “cyber defense.” One secret policy paper dated from January 2010 lists the wide range of information the agency classes as metadata — including location data that could be used to track your movements, your email, instant messenger, and social networking “buddy lists,” logs showing who you have communicated with by phone or email, the passwords you use to access “communications services” (such as an email account), and information about websites you have viewed.

Records showing the full website addresses you have visited — for instance, www.gchq.gov.uk/what_we_do — are treated as content. But the first part of an address you have visited — for instance, www.gchq.gov.uk — is treated as metadata. In isolation, a single metadata record of a phone call, email, or website visit may not reveal much about a person’s private life, according to Ethan Zuckerman, director of Massachusetts Institute of Technology’s Center for Civic Media. But if accumulated and analyzed over a period of weeks or months, these details would be “extremely personal,” he told The Intercept, because they could reveal a person’s movements, habits, religious beliefs, political views, relationships, and even sexual preferences. For Zuckerman, who has studied the social and political ramifications of surveillance, the most concerning aspect of large-scale government data collection is that it can be “corrosive towards democracy” — leading to a chilling effect on freedom of expression and communication. “Once we know there’s a reasonable chance that we are being watched in one fashion or another it’s hard for that not to have a ‘panopticon effect,’” he said, “where we think and behave differently based on the assumption that people may be watching and paying attention to what we are doing.”

When compared to surveillance rules in place in the U.S., GCHQ notes in one document that the U.K. has “a light oversight regime.” The more lax British spying regulations are reflected in secret internal rules that highlight greater restrictions on how NSA databases can be accessed. The NSA’s troves can be searched for data on British citizens, one document states, but they cannot be mined for information about Americans or other citizens from countries in the Five Eyes alliance. No such constraints are placed on GCHQ’s own databases, which can be sifted for records on the phone calls, emails, and Internet usage of Brits, Americans, and citizens from any other country. The scope of GCHQ’s surveillance powers explain in part why Snowden told The Guardian in June 2013 that U.K. surveillance is “worse than the U.S.” In an interview with Der Spiegel in July 2013, Snowden added that British Internet cables were “radioactive” and joked: “Even the Queen’s selfies to the pool boy get logged.”

In recent years, the biggest barrier to GCHQ’s mass collection of data does not appear to have come in the form of legal or policy restrictions. Rather, it is the increased use of encryption technology that protects the privacy of communications that has posed the biggest potential hindrance to the agency’s activities. “The spread of encryption … threatens our ability to do effective target discovery/development,” says a top-secret report co-authored by an official from the British agency and an NSA employee in 2011. “Pertinent metadata events will be locked within the encrypted channels and difficult, if not impossible, to prise out,” the report says, adding that the agencies were working on a plan that would “(hopefully) allow our Internet Exploitation strategy to prevail.”

U.S. government officials have defended the program by asserting it cannot be used on domestic targets without a warrant. But once again, the FISA courts and their super-secret warrants  do not apply to foreign government surveillance of US citizens. So all this sturm and drang about whether or not the US is eavesdropping on our communications is, in fact, irrelevant and diversionary.

In fact, the USA Freedom Act reinstituted a number of the surveillance protocols of Section 215, including  authorization for  roving wiretaps  and tracking “lone wolf terrorists.”  While mainstream media heralded the passage of the bill as restoring privacy rights which were shredded under 215, privacy advocates have maintained that the bill will do little, if anything, to reverse the  surveillance situation in the US. The NSA went on the record as supporting the Freedom Act, stating it would end bulk collection of telephone metadata. However, in light of the reciprocal agreement between the US and Great Britain, the entire hoopla over NSA surveillance, Section 215, FISA courts and the USA Freedom Act could be seen as a giant smokescreen. If Great Britain is collecting our real time phone conversations and turning them over to the NSA, outside the realm or reach of the above stated laws, then all this posturing over the privacy rights of US citizens and surveillance laws expiring and being resurrected doesn’t amount to a hill of CDs.

But in a provision likely to raise concerns from privacy advocates, the administration wants to require DHS to share that information “in as near real time as possible” with other government agencies that have a cybersecurity mission, the official said. Those include the National Security Agency, the Pentagon’s ­Cyber Command, the FBI and the Secret Service. “DHS needs to take an active lead role in ensuring that unnecessary personal information is not shared with intelligence authorities,” Jaycox said. The debates over government surveillance prompted by disclosures from former NSA contractor Edward Snowden have shown that “the agencies already have a tremendous amount of unnecessary information,” he said.

It would reaffirm that federal racketeering law applies to cybercrimes and amends the Computer Fraud and Abuse Act by ensuring that “insignificant conduct” does not fall within the scope of the statute. A third element of the package is legislation Obama proposed Monday to help protect consumers and students against cyberattacks. The theft of personal financial information “is a direct threat to the economic security of American families, and we’ve got to stop it,” Obama said. The plan, unveiled in a speech at the Federal Trade Commission, would require companies to notify customers within 30 days after the theft of personal information is discovered. Right now, data breaches are handled under a patchwork of state laws that the president said are confusing and costly to enforce. Obama’s plan would streamline those into one clear federal standard and bolster requirements for companies to notify customers. Obama is proposing closing loopholes to make it easier to track down cybercriminals overseas who steal and sell identities. “The more we do to protect consumer information and privacy, the harder it is for hackers to damage our businesses and hurt our economy,” he said.

Efforts to pass information-sharing legislation have stalled in the past five years, blocked primarily by privacy concerns. The package also contains provisions that would allow prosecution for the sale of botnets or access to armies of compromised computers that can be used to spread malware, would criminalize the overseas sale of stolen U.S. credit card and bank account numbers, would expand federal law enforcement authority to deter the sale of spyware used to stalk people or commit identity theft, and would give courts the authority to shut down botnets being used for criminal activity, such as denial-of-service attacks.

The administration official stressed that the legislation will require companies to remove unnecessary personal information before furnishing it to the government in order to qualify for liability protection. It also will impose limits on the use of the data for cybersecurity crimes and instances in which there is a threat of death or bodily harm, such as kidnapping, the official said. And it will require DHS and the attorney general to develop guidelines for the federal government’s use and retention of the data. It will not authorize a company to take offensive cyber-measures to defend itself, such as “hacking back” into a server or computer outside its own network to track a breach. The bill also will provide liability protection to companies that share data with private-sector-developed organizations set up specifically for that purpose. Called information sharing and analysis organizations, these groups often are set up by particular industries, such as banking, to facilitate the exchange of data and best practices.

In October, Obama signed an order to protect consumers from identity theft by strengthening security features in credit cards and the terminals that process them. Marc Rotenberg, executive director of the Electronic Privacy Information Center, said there is concern that a federal standard would “preempt stronger state laws” about how and when companies have to notify consumers. The Student Digital Privacy Act would ensure that data entered would be used only for educational purposes. It would prohibit companies from selling student data to third-party companies for purposes other than education. Obama also plans to introduce a Consumer Privacy Bill of Rights. And the White House will host a summit on cybersecurity and consumer protection on Feb. 13 at Stanford University.

The agency notes in the document that it is storing large amounts of “passively tapped network traffic” for “days to months,” encompassing the contents of emails, attachments and other online activity. It adds that it stores some kinds of metadata — data showing who has contacted whom and when, but not the content of the message — for “months to years.” The document says that CSE has “excellent access to full take data” as part of its cyber operations and is receiving policy support on “use of intercepted private communications.” The term “full take” is surveillance-agency jargon that refers to the bulk collection of both content and metadata from Internet traffic. Another top-secret document on the surveillance dated from 2010 suggests the agency may be obtaining at least some of the data by covertly mining it directly from Canadian Internet cables. CSE notes in the document that it is “processing emails off the wire.”
