The Foreign Metadata Problem

In this post, I argued that a likely explanation for the NSA’s limits on collecting domestic cell phone data stem from a decision Verizon made in 2009 to stop participating in an FBI call records program. I’m not sure if I’m right about the cause (I know I’m not right about the timing), but I based part of my argument on how the FISA Court resolved a problem with telecoms turning over foreign data in 2009. And that resolution definitely indicates there’s something different about the way Verizon produces dragnet data from how AT&T does (Sprint is probably a third case, but not as important for these purposes).

Let me be clear: Verizon was not the only telecom to have the problem. It affected at least one other telecom; I believe it may have affected all of them. But the FISC resolved it differently with Verizon, which I believe shows that Verizon complies with the Section 215 orders in different fashion than AT&T and Sprint.

The problem was first identified when, in May 2009, Verizon informed the NSA it had been including foreign-to-foreign records in the data it provided to the NSA. Here’s how David Kris explained it in his report accompanying the phone dragnet end to end report.

NSA advised that for the first time, in May 2009, [redacted--Verizon] stated it produced foreign-to-foreign record pursuant to the Orders. [redacted--Verizon] stopped its production of this set of foreign-to-foreign records on May 29, 2009, after service of the Secondary Order in BR 09-06, which carves out foreign-to-foreign records from the description of records to be produced. (19)

In an accompanying declaration Keith Alexander provided more detail.

In May 2009, during a discussion between NSA and [redacted--Verizon] regarding the production of metadata, a [redacted--Verizon] representative stated that [redacted] produced the records [redacted] pursuant to the BR FISA Orders. This was the first indication that NSA had ever received from [redacted--Verizon] of its contrary understanding. At the May 28, 2009, hearing in docket number BR 09-06, the government informed the Court of [redacted redacted]. To address the issue, based on the government’s proposal, the Court issued a Secondary Order to [redacted] in docket number BR 09-06 that expressly excluded foreign-to-foreign call detail records from the scope of records to be produced. On May 29, 2009, upon service of the Secondary Order in docket number  BR 09-06, [redacted--Verizon] ceased providing foreign-to-foreign records [redacted]. (42/PDF67)

Almost every dragnet order since that May 29, 2009 one has broken its production order out into two subparagraphs to reflect this change.

Screen Shot 2014-11-09 at 11.28.29 AM

We can be virtually certain that Verizon is this provider, because the Verizon secondary order leaked by Edward Snowden includes the language excluding foreign-to-foreign data. That long redaction likely hides Verizon’s full name under this program, “Verizon Business Network Services, Inc. on behalf of MCI Communication Services Inc., d/b/a Verizon Business Services (individually and collectively “Verizon”), which is the name initially used in the secondary order.

Additionally, ODNI originally released the January 20, 2011 primary order with the paragraph that clarifies this with Verizon’s name unredacted. The paragraph remains in the dragnet orders, even after Verizon and Vodaphone split earlier this year (though if the split affected this issue, they may have hidden the fact by retaining the paragraph, given that they’re now anticipating declassification of the orders).

Less than a month after this incident, on June 25, the NSA finished its End-to-End report, which reported just the Verizon issue. Sometime between then and July 9, the FISC appears to have realized one of the other providers had a similar problem. The July 9, 2009 dragnet order, in the only exception I know to the two-part production order, looked like this:

Screen shot 2014-11-09 at 2.07.33 PM

The production order is to plural custodians of records, meaning at least two providers must be named. But it applies the Verizon rules to all of the named providers.

The order also requires an explanation for inclusion of the foreign-to-foreign records (see the bullet at 16-17). It is redacted in the released order but the DOJ submission (see page 6) shows that Judge Walton ordered,

a full explanation of the extent to which NSA has acquired call detail records of foreign-to-foreign communications from [redacted--too long to just be Verizon] pursuant to orders of the FISC, and whether the NSA’s storage, handling, and dissemination of information in those records, or derived therefrom, complied with the Court’s orders;

The September 3, 2009 order reverts to the two-paragraph structure. But it also orders retroactive production from one of the providers (AT&T or Sprint, probably the latter based on redaction length) named in the first paragraph (I first wrote about this here).

In addition, the Custodian of Records of [redacted] shall produce to NSA upon service of the appropriate Secondary Order an electronic copy of the same tangible things created by [redacted] for the period from 5:11 p.m. on July 9, 2009 to the date of this Order, to the extent those records still exist.

And adds a requirement that NSA report on any significant changes in reapplications, including on any changes to how the government obtains the data from carriers.

Any application to renew or reinstate the authority granted herein shall include a report describing: (1) the queries made since the end of the reporting period of the last report filed with the Court; (ii) the manner in which NSA applied the procedures set forth in paragraph (3)C above; and (iii) any proposed changes in the way in which the call detail records would be received from the carriers and any significant changes to the systems NSA uses to receive, store, process, and disseminate BR metadata. [my emphasis]

The DOJ report provides further evidence that at least one other provider provided foreign-to-foreign records. When Kris introduces this problem (see page 18), he references a three part discussion in Alexander’s declaration.

Screen shot 2014-11-09 at 3.52.19 PM

You can see the heading for the third provider on page 46/PDF 71 of the Alexander declaration.

So the report appears to have commented on all three providers. The problem clearly affected two of them.

But FISC only retains the clarification for Verizon.

As I said, I appear to be wrong about the timing of this. I had suggested it was tied to Verizon deciding not to reup its contract under the FBI phone program in 2009. That almost certainly had to have happened (as Charlie Savage noted to me via Twitter, the Exigent Letter IG Report was focused on AT&T, MCI, and Verizon, and one of the latter two, which means basically one part of Verizon, backed out).

But the End-to-End Report makes it clear Verizon first started turning over this data in January 2007.

This foreign-to-foreign metadata started coming into NSA in January 2007. (15)

There was not even a dragnet order signed in January 2007, so it can’t be tied primarily to the phone dragnet. It also preceded the end of the on-site phone provider program (which ended in December 2007) and even the release of the first NSL IG Report in March 2007, which led the providers to get squirrelly (see page 191 for these dates).

The details regarding the potential problems with Verizon’s provision of foreign-to-foreign records suggests this may have something to do with upstream production (Verizon had been providing upstream records to the NSA for years, but it only came under the oversight of the FISC in January 2007).

Furthermore, because the records are records of foreign-to-foreign communications, almost all of them do not concern the communications of U.S. persons. To the extent any of the records concern the communications of U.S. persons, such communications would be afforded the same protections as any other U.S. person communication [redacted] authorities. Id. at 43. (19)

[snip]

almost all of them concern the communications of non-U.S. persons located outside the United States. If NSA were to find that any of the records concerned U.S. persons, their dissemination would be governed by the terms of USSID 18 which are the procedures established pursuant to EO 12333, as amended. (68)

The discussion of records that might “concern the communications” sounds like an “about” search (though I’m not sure of what).

All that said, AT&T should have had the same upstream “about” obligations starting in January 2007 that Verizon did. I suspect (based on my guess that Sprint is the production that got shut down) the order in the July 9, 2009 order is the only instruction they ever got to stop providing foreign-to-foreign records. Yet FISC felt the need — still feels the need — to keep that explicit order to Verizon in every single primary order.

Mind you, all this shows that Verizon was able to shut down the foreign production immediately, on the same day. So it’s clear they can shut down certain kinds of production.

All this seems to suggest that — in addition to at least some part of Verizon withdrawing from the FBI’s records program, and to Verizon not retaining records for the same length of time AT&T does — Verizon also produces phone dragnet data differently than AT&T does.

The Hemisphere Decks: A Comparison and Some Hypotheses

Last week, Dustin Slaughter published a story using a new deck of slides on the Hemisphere program, the Drug Czar program that permits agencies to access additional telecommunications analytical services to identify phones, which then gets laundered through parallel construction to hide both how those phones were found, as well as the existence of the program itself.

It has some significant differences from the deck released by the New York Times last year.  I’ve tried to capture the key differences here:

140915 Hemisphere Comparison

 

The biggest difference is that the NYT deck — which must date to no earlier than June 2013 — draws only from AT&T data, whereas the Declaration deck draws from other providers as well (or rather, from switches used by other providers).

In addition, the Declaration deck seems to reflect approval for use in fewer states (given the mention of CA court orders and the recent authorization to use Hemisphere in Washington in the AT&T deck), and seems to offer fewer analytical bells and whistles.

Thus, I agree with Slaughter that his deck predates — perhaps by some time — the NYT/AT&T deck released last year.  That would mean Hemisphere has lost coverage, even while it has gained new bells and whistles offered by AT&T.

While I’m not yet sure this is my theory of the origin of Hemisphere, some dates are worth noting:

From 2002 to 2006, the FBI had telecoms onsite to provide CDRs directly from their systems (the FBI submitted a great number of its requests without any paperwork). One of the services provided — by AT&T — was community of interest tracking. Presumably they were able to track burner phones (described as dropped phones in these decks) as well.

In 2006, FBI shut down the onsite access, but retained contracts with all 3 providers (AT&T, Verizon, and probably Sprint). In 2009, one telecom — probably Verizon – declined to renew its contract for whatever the contract required.

AT&T definitely still has a contract with FBI, and in recent years, it has added more services to what it offers the FBI.

It’s possible the FBI multi-provider access moved under ONCDP (the Drug Czar) in 2007 as a way to retain its authorities without attracting the attention of DOJ’s excellent Inspector General (who is now investigating this in any case). Though I’m not sure that program provided the local call records the deck at least claims it could have offered. I’m not sure that program got to the telecom switches the way the deck seems to reflect. It’s possible, however, that the phone dragnet in place before it was moved to Section 215 in 2006 did have that direct access to switches, and the program retained this data for some years.

The phone dragnet prior to 2006 and NSL compliance (which is what the contracts with AT&T and one other carrier purportedly provide now) are both authorized in significant part (and entirely, before 2006) through voluntary compliance, per David Kris, the NSA IG Report, and the most recent NSL report. That’s a big reason why the government tried to keep this secret — to avoid any blowback on the providers.

In any case, if I’m right that the program has lost coverage (though gained AT&T’s bells and whistles) in the interim, then it’s probably because providers became unwilling, for a variety of reasons (and various legal decisions on location data are surely one of them) to voluntarily provide such information anymore. I suspect that voluntary compliance got even more circumscribed with the release of the first Horizon deck last year.

Which means the government is surely scrambling to find additional authorities to coerce this continued service.

Did ACLU and EFF Just Help the NSA Get Inside Your Smart Phone?

EFF ACLUThe ACLU and EFF normally do great work defending the Fourth Amendment. Both have fought the government’s expansive spying for years. Both have fought hard to require the government obtain a warrant before accessing your computer, cell phone, and location data.

But earlier this week, they may have taken action that directly undermines that good work.

On Wednesday, both civil liberties organizations joined in a letter supporting Patrick Leahy’s version of USA Freedom Act, calling it a necessary first step.

We support S. 2685 as an important first step toward necessary comprehensive surveillance reform. We urge the Senate and the House to pass it quickly, and without
making any amendments that would weaken the important changes described above.

ACLU’s Laura Murphy explained why ACLU signed onto the bill in a column at Politico, analogizing it to when, in 2010, ACLU signed onto a bill that lowered, but did not eliminate,  disparities in crack sentencing.

Reform advocates were at a crossroads. Maximalists urged opposition despite the fact the bill would, in a very real way, make life better for thousands of people and begin to reduce the severe racial and ethnic inequality in our prison system. Pragmatists, fearing that opposition to the bill would preclude any reform at all, urged support.

It was a painful compromise, but the ACLU ultimately supported the bill. It passed, astoundingly, with overwhelming support in both chambers.

And then something amazing happened. Conservative lawmakers, concerned about government waste, increasingly came to the table to support criminal justice reform. Liberals realized they could vote their conscience on criminal justice without accusations of being “soft on crime.” It has not been easy and there have been many steps backward, but in recent years, we’ve seen greater public opposition to mandatory minimum sentences and real movement on things like reducing penalties for low-level drug offenses.

The analogy is inapt. You don’t end crack disparities by increasing the number of coke dealers in jail. But Leahy’s USA Freedom Act almost certainly will increase the number of totally innocent Americans who will be subjected to the full brunt of NSA’s analytical authorities indefinitely.

That’s because by outsourcing to telecoms, NSA will actually increase the total percentage of Americans’ telephone records that get chained on; sources say it will be more “comprehensive” than the current dragnet and Deputy NSA Director Richard Ledgett agrees the “the actual universe of potential calls that could be queried against is [potentially] dramatically larger.” In addition, the telecoms are unlikely to be able to remove all the noisy numbers like pizza joints — as NSA currently claims to – meaning more people with completely accidental phone ties to suspects will get sucked in. And USA Freedom adopts a standard for data retention — foreign intelligence purpose — that has proven meaningless in the past, so once a person’s phone number gets turned over to the NSA, they’ll be fair game for further NSA spying, the really invasive stuff, indefinitely.

But that’s not the reason I find ACLU and EFF’s early support for USA Freedom so astounding.

I’m shocked ACLU and EFF are supporting this bill because they don’t know what the NSA will be permitted to do at the immunized telecoms. They have blindly signed onto a bill permitting “connection chaining” without first understanding what connection chaining entails.

As I have reported extensively, while every witness who has talked about the phone dragnet has talked about chaining on phone calls made — all the calls Anwar al-Awlaki made, all the calls those people made — the language describing this chaining process has actually been evolving. Dianne Feinstein’s Fake FISA Fix last fall allowed the NSA to chain on actual calls — as witnesses had described — but also on communications (not just calls) “to or from any selector reasonably linked to the selector.” A February modification and the last two dragnet orders permitted NSA to chain on identifiers “with a contact and/or connection” with the seed, making it clear that a “connection” is something different than a “contact.” The House bill USA Freedumber adopted the same language in a legislative report. Leahy’s bill adopts largely the same language for chaining.

(iii) provide that the Government may require the prompt production of call detail records—

(I) using the specific selection term that satisfies the standard required under subsection (b)(2)(C)(ii) as the basis for production; and

(II) using call detail records with a direct connection to such specific selection term as the basis for production of a second set of call detail records;

Now, it’s possible that this language does nothing more than what NSA illegally did until 2009: chain on both the identifier itself, but also on identifiers it has determined to be the same person. Back in 2009, NSA referred to a separate database to determine these other identifiers. Though that’s unlikely, because the bill language suggests the telecoms will be identifying these direct connections.

It’s possible, too, that this language only permits the telecoms to find “burner” phones — a new phone someone adopts after having disposed of an earlier one — and chain on that too.

But it’s also possible that this language would permit precisely what AT&T does for DEA in its directly analogous Hemisphere program: conduct analysis using cell site data. The bill does not permit NSA to receive cell site data, but it does nothing to prohibit NSA from receiving phone numbers identified using cell site data. When Mark Warner asked about this, Ledgett did not answer, and James Cole admitted they could use these orders (with FISC approval) to get access to cell location.

It’s possible, too, that the telecoms will identify direct connections using other data we know NSA uses to identify connections in EO 12333 data, including phone book and calendar data.

The point is, nobody in the public knows what “connections” NSA will be asking its immunized telecom partners to make. And nothing in the bill or even the public record prohibits NSA from asking telecoms to use a range of smart phone information to conduct their analysis, so long as they only give NSA phone identifiers as a result.

In response to questions from Senators about what this means, Leahy’s office promised a letter from James Clapper’s office clarifying what “connections” means (No, I don’t remember the part of Schoolhouse Rock where those regulated by laws get to provide “clarifications” that don’t make it into the laws themselves). That letter was reported to be due on Tuesday, by close of business — several days ago. It hasn’t appeared yet.

I asked people at both EFF and ACLU about this problem. EFF admitted they don’t know what this language means. ACLU calls the language “ambiguous,” but based on nothing they were able to convey to me, insists getting smart phone data under the guise of connection chaining would be an abuse. ACLU also pointed to transparency provisions in the bill, claiming that would alert us if the NSA starting doing something funky with its connection language; that of course ignores that “connection chaining” is an already-approved process, meaning that existing processes won’t ever be need to be released. It also ignores that the Administration has withheld what is probably a directly relevant phone dragnet opinion from both ACLU and EFF in their dragnet FOIA.

I get Laura Murphy’s point about using USA Freedom to start the process of reform. But what I don’t understand is why you’d do that having absolutely no idea whether that “reform” codifies the kind of warrantless probable cause-free access to device data that ACLU and EFF have fought so hard to prevent elsewhere.

ACLU and EFF are supposed to be leaders in protecting the privacy of our devices, including smart phones. I worry with their embrace of this bill, they’re leading NSA right into our smart phones.

Microsoft’s Very Public Spat in the Cloud

A few weeks back, I did a Salon piece laying out how both the US and UK were claiming they can demand data stored in a cloud in any country. The UK is doing that with their new DRIP law, which will increase their ability to demand data from companies within and outside of the UK. The US is doing that by serving warrants on US companies for data stored in their clouds overseas.

The next battle in the latter war will take place on Thursday, at a hearing in NYC. In anticipation, Microsoft’s counsel Brad Smith wrote a WSJ op-ed to make the spat good and public. Here’s how he describes the government’s efforts to use Third Party doctrine to get around border limits on warrants.

Microsoft believes you own emails stored in the cloud, and that they have the same privacy protection as paper letters sent by mail. This means, in our view, that the U.S. government can obtain emails only subject to the full legal protections of the Constitution’s Fourth Amendment. It means, in this case, that the U.S. government must have a warrant. But under well-established case law, a search warrant cannot reach beyond U.S. shores.

The government seeks to sidestep these rules, asserting that emails you store in the cloud cease to belong exclusively to you. In court filings, it argues that your emails become the business records of a cloud provider. Because business records have a lower level of legal protection, the government claims that it can use its broader authority to reach emails stored anywhere in the world.

Courts have long recognized the distinction between a company’s business records and an individual’s personal communications. For example, the government can serve a subpoena on UPS to disclose business records that show where a customer shipped packages, but it must establish probable cause and get a warrant from a judge to look at what a customer put inside.

[snip]

Microsoft believes the higher legal protection for personal conversations should be preserved for new forms of digital communication, such as emails or text and instant messaging.

This is a battle about cloud storage. But it’s also a proxy war for questions of how the government conducts its more secret surveillance — as well as a very public show of opposing the government’s more expansive claims (the amici in this case include other companies — like AT&T — that have never complained about the government’s surveillance requests but that have good reason to make a good show of complaining here).

Which makes it interesting that Microsoft is so aggressively reaching out to the public.

 

The Anglo-American Data Empire

In a piece for Salon today, I note that both in US domestic warrants for Stored Communication and in the law the UK will push through, DRIP, the US and the Brits are asserting they should be able to demand data stored anywhere in the world. Here’s the US part:

The U.S. data grab started back in December, when the Department of Justice applied for a warrant covering an email account Microsoft held in Ireland as part of a drug-trafficking investigation. Microsoft complied with regards to the information it stored in the U.S. (which consisted of subscriber information and address books), but challenged the order for the content of the emails. After Magistrate Judge James Francis sided with the government – arguing, in part, that Mutual Legal Assistance Treaties, under which one country asks another for help on a legal investigation, were too burdensome — Microsoft appealed, arguing the government had conscripted it to conduct an extraterritorial search and seizure on its behalf.

As part of that, Microsoft Vice President Rajesh Jha described how, since Snowden’s disclosures, “Microsoft partners and enterprise customers around the world and across all sectors have raised concerns about the United States Government’s access to customer data stored by Microsoft.” Jha explained these concerns went beyond NSA’s practices. “The notion of United States government access to such data — particularly without notice to the customer — is extremely troubling to our partners and enterprise customers located outside of the United States.” Some of those customers even raised Magistrate Francis’ decision specifically.

[snip]

The government’s response, however, argued U.S. legal process is all that is required. DOJ’s brief scoffed at Microsoft for raising the real business concerns that such big-footing would have on the U.S. industry. “The fact remains that there exists probable cause to believe that evidence of a violation of U.S. criminal law, affecting U.S. residents and implicating U.S. interests, is present in records under Microsoft’s control,” the government laid out. It then suggested U.S. protection for Microsoft’s intellectual property is the tradeoff Microsoft makes for complying with legal process. “Microsoft is a U.S.-based company, enjoying all the rights and privileges of doing business in this country, including in particular the protection of U.S. intellectual property laws.” It ends with the kind of scolding usually reserved for children. “Microsoft should not be heard to complain that doing so might harm its bottom line. ”

Click through to find out why the UK data grab is even worse.

Effectively, both English speaking behemoths are arguing that borders don’t matter, they can have any data in the world. And while we know NSA and GCHQ were doing that for spying purposes, here they’re arguing they can do it for crime prevention.

Breathtaking claims, really.

Sadness in the NSA-Telecom Bromance

In his report on an interview with the new Director of NSA, Admiral Mike Rogers, David Sanger gets some operational details wrong, starting with his claim that the new phone dragnet would require an “individual warrant.”

The new phone dragnet neither requires “warrants” (the standard for an order is reasonable suspicion, not probable cause), nor does it require its orders to be tied to “individuals,” but instead requires “specific selection terms” that may target facilities or devices, which in the past have been very very broadly interpreted.

All that said, I am interested in Rogers’ claims Sanger repeats about NSA’s changing relationship with telecoms.

He also acknowledged that the quiet working relationships between the security agency and the nation’s telecommunications and high technology firms had been sharply changed by the Snowden disclosures — and might never return to what they once were in an era when the relationships were enveloped in secrecy.

Oh darn!

Sadly, here’s where Sanger’s unfamiliarity with the details makes the story less useful. Publicly, at least, AT&T and Verizon have had significantly different responses to the exposure of the dragnet (though that may only be because Verizon’s name has twice been made public in conjunction with NSA’s dragnet, whereas AT&T’s has not been), and it’d be nice if this passage probed some of those details.

Telecommunications businesses like AT&T and Verizon, and social media companies, now insist that “you are going to have to compel us,” Admiral Rogers said, to turn over data so that they can demonstrate to foreign customers that they do not voluntarily cooperate. And some are far more reluctant to help when asked to provide information about foreigners who are communicating on their networks abroad. It is a gray area in the law in which American courts have no jurisdiction; instead, the agency relied on the cooperation of American-based companies.

Last week, Verizon lost a longstanding contract to run many of the telecommunications services for the German government. Germany declared that the revelations of “ties revealed between foreign intelligence agencies and firms” showed that it needed to rely on domestic providers.

After all, under Hemisphere, AT&T wasn’t requiring legal process even for domestic call records. I think it possible they’ve demanded the government move Hemisphere under the new phone dragnet, though if they have, we haven’t heard about it (it would only work if they defined domestic drug dealer suspects as associated with foreign powers who have some tie to terrorism). Otherwise, though, AT&T has not made a peep to suggest they’ll alter their decades-long overenthusiastic cooperation with the government.

Whereas Verizon has been making more audible complaints about their plight, long before the Germans started ending their contracts. And Sprint — unmentioned by Sanger — even demanded to see legal support for turning over phone data, including, apparently, turning over foreign phone data under ECPA;s exception in 18 U.S.C. § 2511(2)(f)‘s permitting telecoms to voluntarily provide foreign intelligence data. 

Given that background — and the fact ODNI released the opinions revealing Sprint’s effort, if not its name — I am curious whether the telecoms are really demanding process. If courts really had no jurisdiction then it is unclear how the government could obligate production

Though that may be what the Microsoft’s challenge to a government request for email held in Ireland is about, and that may explain why AT&T and Verizon, along with Cisco and Apple — for the most part, companies that have been more reticent about the government obtaining records in the US — joined that suit. (In related news, EU Vice President Viviane Reding says the US request for the data may be a violation of international law.)

Well, if the Microsoft challenge and telecom participation in the request for data overseas is actually an effort to convince the Europeans these corporations are demanding legal process, Admiral Rogers just blew their cover.

Admiral Rogers said the majority of corporations that had long given the agency its technological edge and global reach were still working with it, though they had no interest in advertising the fact.

Dear Ireland and the rest of Europe: Microsoft — which has long been rather cooperative with NSA, up to and including finding a way to obtain Skype data — may be fighting this data request just for show. Love, Microsoft’s BFF, Mike Rogers.

Four Reasons USA Freedumber is Worse than the Status Quo

In the post-HR 3361 passage press conference yesterday, Jerry Nadler suggested the only reason civil libertarians oppose the bill is because it does not go far enough.

That is, at least in my case, false.

While I have concerns about unintended consequences of outsourcing holding the call data to the telecoms (see my skepticism that it ends bulk collection here and my concerns about high volume numbers here), there are a number of ways that USA Freedumber is worse than the status quo.

These are:

  • The move to telecoms codifies changes in the chaining process that will almost certainly expand the universe of data being analyzed
  • In three ways, the bill permits phone chaining for purposes outside of counterterrorism
  • The bill weakens minimization procedures on upstream collection imposed by John Bates, making it easier for the government to collect domestic content domestically
  • The bill guts the current controls on Pen Register authority, making it likely the government will resume its Internet dragnet

The NSA in your smart phone: Freedumber codifies changes to the chaining process

As I have described, the language in USA Freedumber makes it explicit that the government and its telecom partners can chain on connections as well as actual phone call contacts. While the new automatic search process approved by the FISA Court in 2012 included such chaining, by passing this bill Congress endorses this approach. Moreover, the government has never been able to start running such automatic queries; it appears they have to outsource to the telecoms to be able to do so (probably in part to make legal and technical use of location data). Thus, moving the phone chaining to the telecoms expands on the kinds of chaining that will be done with calls.

We don’t know all that that entails. At a minimum (and, assuming the standard of proof is rigorous, uncontroversially) the move will allow the government to track burner phones, the new cell phones targets adopt after getting rid of an old one.

It also surely involves location mapping. I say that, in part, because if they weren’t going to use location data, they wouldn’t have had to move to the telecoms. In addition, AT&T’s Hemisphere program uses location data, and it would be unrealistic to assume this program wouldn’t include at least all of what Hemisphere already does.

But beyond those two functions, your guess is as good as mine. While the chaining must produce a Call Detail Record at the interim step (which limits how far away from actual phone calls the analysis can get), it is at least conceivable the chaining could include any of a number of kinds of data available to the telecoms from smart phones, including things like calendars, address books, and email.

The fact that the telecoms and subsidiary contractors get immunity and compensation makes it more likely that this new chaining will be expansive, because natural sources of friction on telecom cooperation will have been removed.

Freedumber provides three ways for NSA to use the phone dragnet for purposes besides counterterrorism

As far as we know, the current dragnet may only be used for actual terrorist targets and Iran. But USA Freedumber would permit the government to use the phone dragnet to collect other data by:

  • Requiring only that selection terms be associated with a foreign power
  • Permitting the retention of data for foreign intelligence, not just counterterrorism, purposes
  • Allowing the use of emergency queries for non-terrorism uses

Freedumber permits searches on selection terms associated with foreign powers

On its face, USA Freedumber preserves this counterterrorism focus, requiring any records obtained to be “relevant to” an international terrorist investigation. Unfortunately, we now know that FISC has already blown up the meaning of “relevant to,” making all data effectively relevant.

The judicial approval of the specific selection term, however — the court review that should be an improvement over the status quo — is not that tie to terrorism, but evidence that the selection term is a foreign power or agent thereof.

Thus, the government could cite narcoterrorism, and use the chaining program to investigate Mexican drug cartels. The government could raise concerns that al Qaeda wants to hack our networks, and use chaining to investigate hackers with foreign ties. The government could allege Venezuela supports terrorism and investigate Venezuelan government sympathizers.

There are a whole range of scenarios in which the government could use this chaining program for purposes other than counterterrorism.

Freedumber permits the retention of any data that serves a foreign intelligence purpose

And once it gets that data, the government can keep it, so long as it claims (to itself, with uncertain oversight from the FISC) that the data has a foreign intelligence purpose.

At one level, this is a distinction without a difference from the language that USA Freedumb had used, which required the NSA to destroy the data after five years unless it was relevant to a terrorism investigation (which all data turned over to NSA would be, by definition). But the change in language serves as legislative approval that the use of the data received via this program can be used for other purposes.

That will likely have an impact on minimization procedures. Currently, the NSA needs a foreign intelligence purpose to access the corporate store, but can only disseminate data from it for counterterrorism purposes. I would imagine the changed language of the bill will lead the government to successfully argue that the minimization procedures permit the dissemination of US person data so long as it meets only this flimsy foreign intelligence purpose. In other words, US person data collected in chaining would be circulating around the government more freely.

Freedumber’s emergency queries do not require any tie to terrorism

As I noted, the revisions USA Freedumber made to USA Freedumb explicitly removed a requirement that emergency queries be tied to a terrorism investigation.

(A) reasonably determines that an emergency situation requires the production of tangible things to obtain information for an authorized investigation (other than a threat assessment) conducted in accordance with subsection (a)(2) to protect against international terrorism before an order authorizing such production can with due diligence be obtained;

That’s particularly troublesome, because even if the FISC rules the emergency claim (certified by the Attorney General) was not legally valid after the fact, not only does the government not have to get rid of that data, but the Attorney General (the one who originally authorized its collection) is the one in charge of making sure it doesn’t get used in a trial or similar proceeding.

In short, these three changes together permit the government to use the phone dragnet for a lot more uses than they currently can.

Freedumber invites the expansion of upstream collection

When John Bates declared aspects of upstream collection to be unconstitutional in 2011, he used the threat of referrals under 50 USC 1809(a) to require the government to provide additional protection both to entirely domestic communications that contained a specific selector, and to get rid of domestic communications that did not contain that specific selector at all. The government objected (and considered appealing), claiming that because it hadn’t really intended to collect this data, it should be able to keep it and use it. But ultimately, that threat (especially threats tied to the government’s use of this data for ongoing FISA orders) led the government to capitulate.

The changes in Freedumber basically allow the government to adopt its old “intentional” claim, reversing Bates’ restrictions. Continue reading

DOJ Inspector General Investigating DEA’s Use of Parallel Construction under Hemisphere

Screen Shot 2014-04-18 at 11.02.49 AMAs I noted in my last post, DOJ’s Inspector General recently created a page showing their ongoing investigations. It shows some things not described in Inspector General Michael Horowitz’ last report to Congress.

Of particular interest is this investigation.

Administrative Subpoenas

The OIG is examining the DEA’s use of administrative subpoenas to obtain broad collections of data or information. The review will address the legal authority for the acquisition or use of these data collections; the existence and effectiveness of any policies and procedural safeguards established with respect to the collection, use, and retention of the data; the creation, dissemination, and usefulness of any products generated from the data; and the use of “parallel construction” or other techniques to protect the confidentiality of these programs.

The description doesn’t say it, but this is Hemisphere, the program under which DEA submits administrative subpoenas to AT&T for phone records from any carrier that uses AT&T’s backbone. DEA gets information matching burner phones as well as the call records. In addition, it gets some geolocation — and continued to increase what it was getting even after US v Jones raised concerns about such tracking.

The presentation on Hemisphere makes it very clear the government uses “parallel construction” to hide Hemisphere.

Protecting the Program: When a complete set of CDRs are subpoenaed from the carrier, then all memorialized references to relevant and pertinent calls can be attributed to the carrier’s records, thus “walling off” the information obtained from Hemisphere. In other words, Hemisphere can easily be protected if it is used as a pointed system to uncover relevant numbers.

Exigent Circumstances — Protecting the Program: In special cases, we realize that it might not be possible to obtain subpoenaed phone records that will “wall off” Hemisphere. In these special circumstances, the Hemisphere analyst should be contacted immediately. The analyst will work with the investigator and request a separate subpoena to AT&T.

Official Reporting — Protecting the Program: All requestors are instructed to never refer to Hemisphere in any official document. If there is no alternative to referencing a Hemisphere request, then the results should be referenced as information obtained from an AT&T subpoena.

And this is not the only area where DEA Is using parallel construction to hide where it gets its investigative leads. Reuters reported in August that DEA also uses parallel construction to hide the leads it gets from purportedly national security-related wiretapping.

A secretive U.S. Drug Enforcement Administration unit is funneling information from intelligence intercepts, wiretaps, informants and a massive database of telephone records to authorities across the nation to help them launch criminal investigations of Americans.

Although these cases rarely involve national security issues, documents reviewed by Reuters show that law enforcement agents have been directed to conceal how such investigations truly begin – not only from defense lawyers but also sometimes from prosecutors and judges.

The undated documents show that federal agents are trained to “recreate” the investigative trail to effectively cover up where the information originated, a practice that some experts say violates a defendant’s Constitutional right to a fair trial. If defendants don’t know how an investigation began, they cannot know to ask to review potential sources of exculpatory evidence – information that could reveal entrapment, mistakes or biased witnesses.

[snip]

The two senior DEA officials, who spoke on behalf of the agency but only on condition of anonymity, said the process is kept secret to protect sources and investigative methods. “Parallel construction is a law enforcement technique we use every day,” one official said. “It’s decades old, a bedrock concept.”

A dozen current or former federal agents interviewed by Reuters confirmed they had used parallel construction during their careers. Most defended the practice; some said they understood why those outside law enforcement might be concerned.

Presuming that Horowitz is investigating whether DEA’s extensive use of parallel construction complies with the Constitution (and not, as is possible, whether the sources of this information are being adequately buried), this is welcome news indeed.

But it’s also one of several reasons why I’m particularly alarmed, in retrospect, that Horowitz is complaining about his ability to get grand jury information without having to get either Attorney General Holder or Deputy Attorney General James Cole to personally approve it.

After all, the only way you can learn what truly happens in prosecutions that have used parallel construction to hide their sources is to work backward from the actual prosecution. Continue reading

A Key Part of RuppRoge’s Fake Dragnet Fix Reform: Pay the Telecoms

Here’s an interesting “reform” in the RuppRoge’s Fake Dragnet Fix. It pays the telecoms.

COMPENSATION AND ASSISTANCE.–The Government shall compensate, at the prevailing rate, an electronic communications service provider for providing records in accordance with directives issued pursuant to [their bill].

Section 215 does not include such a payment provision. And while the first two phone dragnet orders included provision for such payments, that was probably illegal.

Don’t get me wrong. I’m sure the government has found some way to pay the telecoms, either through added payments for AT&T’s Hemisphere program or gifts in kind. (Though given the timing of DOJ’s suit against Sprint for over-billing, I do wonder whether the government is retaliating for something.) Telecoms don’t spy for free, so I’m sure they’ve been getting paid, illegally, for the last 8 years of dragnet spying they’ve been doing.

But the lack of such provision in Section 215 should have limited the scope of the dragnet. It should have required that requests be so narrow no telecom was going to send big bills to the government every month. And it presumably made the telecoms (well, except for AT&T, which never met a spying request it didn’t love) less willing to interpret orders from the government expansively.

The inclusion of such a compensation clause in the RuppRoge “reform” makes it even more likely this dragnet will expand with the now well-oiled willingness of the telecoms to go above and beyond the letter of the request.

Which is presumably just how the NSA wants it to be.

Verizon VP: Company-Based Transparency Reports Don’t Help Consumers

There was a fascinating panel of Telecom execs and bloggers discussing human rights at RightsCon yesterday. Among others, Verizon Executive Vice President and General Counsel Randal Milch spoke.

As I noted in passing, Verizon published an update to their Transparency Report the other day. Particularly as compared to AT&T’s bogus report, the Verizon report was laudable for its explanation of what it couldn’t show, such as when it acknowledged that its report did not include the hundreds of millions of customers whose records got turned over under Section 215.

We note that while we now are able to provide more information about national security orders that directly relate to our customers, reporting on other matters, such as any orders we may have received related to the bulk collection of non-content information, remains prohibited.

It also acknowledged something obvious but that which should be explicit: when the government obtains content from Verizon, it sometimes gets metadata as well.

Some FISA orders that seek content also seek non-content; we counted those as FISA orders for content and to avoid double counting have not also counted them as FISA orders for non-content.

All this is useful information that lends the report itself credibility.

So when I first approached Milch, I thanked him for the quality of his report.

Which is why I was so surprised when he said the government should be in the business of transparency reports, not the providers. I challenged that, noting that an easy comparison of AT&T and Verizon’s reports strongly suggests that Verizon demands more legal process for requests than AT&T. He dismissed that, suggesting any differences arise from the different kind of client base the providers have.

Granted, Milch was talking about your average consumer, not … me.

But it seemed bizarre. Or perhaps it was a testament that Milch and Verizon generally don’t want to have to compete in this front.

Milch answered one other question of mine: I asked whether the Verizon/Vodaphone split affected Verizon’s obligations to the UK (that is, to GCHQ). He claims it didn’t affect it at all, that it was more an investment stake and that none of Verizon’s cell call records were in the UK. (No, I didn’t point out that the records are right where GCHQ wants them, in places accessible under Tempora).

So at least according to Milch’s claims, my theory laid out here is wrong.
