One presentation claims the XKeyscore program covers ‘nearly everything a typical user does on the internet’

A top secret National Security Agency program allows analysts to search with no prior authorization through vast databases containing emails, online chats and the browsing histories of millions of individuals, according to documents provided by whistleblower Edward Snowden.

The NSA boasts in training materials that the program, called XKeyscore, is its “widest-reaching” system for developing intelligence from theinternet.

The latest revelations will add to the intense public and congressional debate around the extent of NSA surveillance programs. They come as senior intelligence officials testify to the Senate judiciary committee on Wednesday, releasing classified documents in response to the Guardian’s earlier stories on bulk collection of phone records and Fisasurveillance court oversight.

The files shed light on one of Snowden’s most controversial statements, made in his first video interview published by the Guardian on June 10.

“I, sitting at my desk,” said Snowden, could “wiretap anyone, from you or your accountant, to a federal judge or even the president, if I had a personal email”.

US officials vehemently denied this specific claim. Mike Rogers, the Republican chairman of the House intelligence committee, said of Snowden’s assertion: “He’s lying. It’s impossible for him to do what he was saying he could do.”

But training materials for XKeyscore detail how analysts can use it and other systems to mine enormous agency databases by filling in a simple on-screen form giving only a broad justification for the search. The request is not reviewed by a court or any NSA personnel before it is processed.

XKeyscore, the documents boast, is the NSA’s “widest reaching” system developing intelligence from computer networks – what the agency calls Digital Network Intelligence (DNI). One presentation claims the program covers “nearly everything a typical user does on the internet”, including the content of emails, websites visited and searches, as well as theirmetadata.

Analysts can also use XKeyscore and other NSA systems to obtain ongoing “real-time” interception of an individual’s internet activity.

Under US law, the NSA is required to obtain an individualized Fisawarrant only if the target of their surveillance is a ‘US person’, though no such warrant is required for intercepting the communications of Americans with foreign targets. But XKeyscore provides the technological capability, if not the legal authority, to target even US persons for extensive electronic surveillance without a warrant provided that some identifying information, such as their email or IP address, is known to the analyst.

One training slide illustrates the digital activity constantly being collected by XKeyscore and the analyst’s ability to query the databases at any time.

The purpose of XKeyscore is to allow analysts to search the metadata as well as the content of emails and other internet activity, such as browser history, even when there is no known email account (a “selector” in NSAparlance) associated with the individual being targeted.

Analysts can also search by name, telephone number, IP address, keywords, the language in which the internet activity was conducted or the type of browser used.

One document notes that this is because “strong selection [search by email address] itself gives us only a very limited capability” because “a large amount of time spent on the web is performing actions that are anonymous.”

The NSA documents assert that by 2008, 300 terrorists had been captured using intelligence from XKeyscore.

Analysts are warned that searching the full database for content will yield too many results to sift through. Instead they are advised to use themetadata also stored in the databases to narrow down what to review.

A slide entitled “plug-ins” in a December 2012 document describes the various fields of information that can be searched. It includes “every email address seen in a session by both username and domain”, “every phone number seen in a session (eg address book entries or signature block)” and user activity – “the webmail and chat activity to include username, buddylist, machine specific cookies etc”.

Email monitoring

In a second Guardian interview in June, Snowden elaborated on his statement about being able to read any individual’s email if he had their email address. He said the claim was based in part on the email search capabilities of XKeyscore, which Snowden says he was authorized to use while working as a Booz Allen contractor for the NSA.

One top-secret document describes how the program “searches within bodies of emails, webpages and documents”, including the “To, From, CC, BCC lines” and the ‘Contact Us’ pages on websites”.

To search for emails, an analyst using XKS enters the individual’s email address into a simple online search form, along with the “justification” for the search and the time period for which the emails are sought.

The analyst then selects which of those returned emails they want to read by opening them in NSA reading software.

The system is similar to the way in which NSA analysts generally can intercept the communications of anyone they select, including, as one NSA document put it, “communications that transit the United States and communications that terminate in the United States”.

One document, a top secret 2010 guide describing the training received by NSA analysts for general surveillance under the Fisa Amendments Act of 2008, explains that analysts can begin surveillance on anyone by clicking a few simple pull-down menus designed to provide both legal and targeting justifications. Once options on the pull-down menus are selected, their target is marked for electronic surveillance and the analyst is able to review the content of their communications:

Chats, browsing history and other internet activity

Beyond emails, the XKeyscore system allows analysts to monitor a virtually unlimited array of other internet activities, including those within social media.

An NSA tool called DNI Presenter, used to read the content of stored emails, also enables an analyst using XKeyscore to read the content of Facebook chats or private messages.

KS55edit 

An analyst can monitor such Facebook chats by entering the Facebook user name and a date range into a simple search screen.

KS6 

Analysts can search for internet browsing activities using a wide range of information, including search terms entered by the user or the websites viewed.

KS7 

As one slide indicates, the ability to search HTTP activity by keyword permits the analyst access to what the NSA calls “nearly everything a typical user does on the internet”.

KS8 

The XKeyscore program also allows an analyst to learn the IP addresses of every person who visits any website the analyst specifies.

KS9 

The quantity of communications accessible through programs such as XKeyscore is staggeringly large. One NSA report from 2007 estimated that there were 850bn “call events” collected and stored in the NSA databases, and close to 150bn internet records. Each day, the document says, 1-2bn records were added.

William Binney, a former NSA mathematician, said last year that the agency had “assembled on the order of 20tn transactions about US citizens with other US citizens”, an estimate, he said, that “only was involving phone calls and emails”. A 2010 Washington Post article reported that “every day, collection systems at the [NSA] intercept and store 1.7bn emails, phone calls and other type of communications.”

The XKeyscore system is continuously collecting so much internet data that it can be stored only for short periods of time. Content remains on the system for only three to five days, while metadata is stored for 30 days. One document explains: “At some sites, the amount of data we receive per day (20+ terabytes) can only be stored for as little as 24 hours.”

To solve this problem, the NSA has created a multi-tiered system that allows analysts to store “interesting” content in other databases, such as one named Pinwale which can store material for up to five years.

It is the databases of XKeyscore, one document shows, that now contain the greatest amount of communications data collected by the NSA.

KS10 

In 2012, there were at least 41 billion total records collected and stored in XKeyscore for a single 30-day period.

KS11 

Legal v technical restrictions

While the Fisa Amendments Act of 2008 requires an individualized warrant for the targeting of US persons, NSA analysts are permitted to intercept the communications of such individuals without a warrant if they are in contact with one of the NSA’s foreign targets.

The ACLU’s deputy legal director, Jameel Jaffer, told the Guardian last month that national security officials expressly said that a primary purpose of the new law was to enable them to collect large amounts of Americans’ communications without individualized warrants.

“The government doesn’t need to ‘target’ Americans in order to collect huge volumes of their communications,” said Jaffer. “The government inevitably sweeps up the communications of many Americans” when targeting foreign nationals for surveillance.

An example is provided by one XKeyscore document showing an NSAtarget in Tehran communicating with people in Frankfurt, Amsterdam and New York.

KS12 

In recent years, the NSA has attempted to segregate exclusively domestic US communications in separate databases. But even NSA documents acknowledge that such efforts are imperfect, as even purely domestic communications can travel on foreign systems, and NSA tools are sometimes unable to identify the national origins of communications.

Moreover, all communications between Americans and someone on foreign soil are included in the same databases as foreign-to-foreign communications, making them readily searchable without warrants.

Some searches conducted by NSA analysts are periodically reviewed by their supervisors within the NSA. “It’s very rare to be questioned on our searches,” Snowden told the Guardian in June, “and even when we are, it’s usually along the lines of: ‘let’s bulk up the justification’.”

In a letter this week to senator Ron Wyden, director of national intelligence James Clapper acknowledged that NSA analysts have exceeded even legal limits as interpreted by the NSA in domestic surveillance.

Acknowledging what he called “a number of compliance problems”, Clapper attributed them to “human error” or “highly sophisticated technology issues” rather than “bad faith”.

However, Wyden said on the Senate floor on Tuesday: “These violations are more serious than those stated by the intelligence community, and are troubling.”

In a statement to the Guardian, the NSA said: “NSA’s activities are focused and specifically deployed against – and only against – legitimate foreign intelligence targets in response to requirements that our leaders need for information necessary to protect our nation and its interests.

“XKeyscore is used as a part of NSA’s lawful foreign signals intelligence collection system.

“Allegations of widespread, unchecked analyst access to NSA collection data are simply not true. Access to XKeyscore, as well as all of NSA’s analytic tools, is limited to only those personnel who require access for their assigned tasks … In addition, there are multiple technical, manual and supervisory checks and balances within the system to prevent deliberate misuse from occurring.”

“Every search by an NSA analyst is fully auditable, to ensure that they are proper and within the law.

“These types of programs allow us to collect the information that enables us to perform our missions successfully – to defend the nation and to protect US and allied troops abroad.”

Glenn Greenwald: Low-Level NSA Analysts Have ‘Powerful and Invasive’ Search Tool

ABC glenn greenwald this week jt 130728 16x9 608 Glenn Greenwald: Low Level NSA Analysts Have Powerful and Invasive Search ToolABC News

Today on “This Week,” Glenn Greenwald – the reporter who broke the story about the National Security Agency’s surveillance programs – claimed that those NSA programs allowed even low-level analysts to search the private emails and phone calls of Americans.

“The NSA has trillions of telephone calls and emails in their databases that they’ve collected over the last several years,” Greenwald told ABC News’ George Stephanopoulos. “And what these programs are, are very simple screens, like the ones that supermarket clerks or shipping and receiving clerks use, where all an analyst has to do is enter an email address or an IP address, and it does two things.  It searches that database and lets them listen to the calls or read the emails of everything that the NSA has stored, or look at the browsing histories or Google search terms that you’ve entered, and it also alerts them to any further activity that people connected to that email address or that IP address do in the future.”

Greenwald explained that while there are “legal constraints” on surveillance that require approval by the FISA court, these programs still allow analysts to search through data with little court approval or supervision.

“There are legal constraints for how you can spy on Americans,” Greenwald said. “You can’t target them without going to the FISA court. But these systems allow analysts to listen to whatever emails they want, whatever telephone calls, browsing histories, Microsoft Word documents.”

“And it’s all done with no need to go to a court, with no need to even get supervisor approval on the part of the analyst,” he added.

But the top Republican on the  Senate Intelligence Committee told Stephanopoulos he would be shocked if such programs existed.

“It wouldn’t just surprise me, it would shock me,” Sen. Saxby Chambliss, R-Georgia, said on “This Week” Sunday.

Chambliss said he recently spent time with NSA officials and was assured that the programs Greenwald describes have been exaggerated.

“I was back out at NSA just last week, spent a couple hours out there with high and low level NSA officials,” Chambliss said. “And what I have been assured of is that there is no capability at NSA for anyone without a court order to listen to any telephone conversation or to monitor any e-mail.”

Chambliss said that any monitoring of emails is purely “accidental.”

“In fact, we don’t monitor emails. That’s what kind of assures me is that what the reporting is is not correct. Because no emails are monitored now,” Chambliss said. “They used to be, but that stopped two or three years ago. So I feel confident that there may have been some abuse, but if it was it was pure accidental.”

Greenwald is set to testify before a Congressional committee on Wednesday, along with NSA officials. He said the existence of these analyst search programs are in line with the claims of Edward Snowden, who first leaked details of the NSA’s surveillance programs to Greenwald.

“It’s an incredibly powerful and invasive tool, exactly of the type that Mr. Snowden described,” Greenwald said.

NSA Director Gen. Keith Alexander and House Intelligence leaders have previously downplayedSnowden’s access to NSA data. Ahead of his Congressional testimony, Greenwald said the revelation of this search capability deserves a response from NSA officials.

“NSA officials are going to be testifying before the Senate on Wednesday, and I defy them to deny that these programs work exactly as I just said,” Greenwald said.

Greenwald also called on lawmakers to push for more information about the NSA’s surveillance programs.

“The real issue here is that what the NSA does is done in complete secrecy. Nobody really monitors who they are eavesdropping on,” Greenwald said. “So the question of abuse is one that the Congress ought to be investigating much more aggressively.”

Snowden, the former NSA contractor who leaked information about two sweeping intelligence programs, has previously warned that they are open to abuse by those with access. In a video interview with The Guardian, he said, “Any analyst at any time can target anyone… I, sitting at my desk, had the authority to wiretap anyone, from you or your accountant to a federal judge to even the president if I had a personal email.”

Snowden has been holed up in a Moscow airport for weeks. He is currently attempting to secure temporary asylum in Russia on the grounds that he would be tortured or face the death penalty if he returned to the United States.

Attorney General Eric Holder responded to Snowden’s appeal last week, writing in a letter to the Russian government, “These claims are entirely without merit.”

FULL COVERAGE: Edward Snowden

Today, Greenwald told Stephanopoulos that Snowden’s petition is still pending, but the former NSA contractor prefers that the focus be elsewhere.

“I think he’s content with having nothing happen so the focus isn’t on him, but is on the substance of the revelations that he came forward to shine light on,” Greenwald said.
