Keith Alexander Refutes Claims NSA Doesn't Get Cell Data | emptywheel - 0 views

Eight days ago, the country’s four major newspapers reported a claim that the NSA collected 33% or less of US phone records (under the Section 215 program, they should have specified, but did not) because it couldn’t collect most cell phone metadata:

Since that time, I have pointed to a number of pieces of evidence that suggest these claims are only narrowly true: A WSJ article from June made it clear the cell gap, such as it existed, existed primarily for Verizon and T-Mobile, but their calls were collected via other means (the WaPo and NYT both noted this in their stories without considering how WSJ’s earlier claim it was still near-comprehensive contradicted the 33% claim) The NSA’s claimed Section 215 dragnet successes — Basaaly Moalin, Najibullah Zazi, Tsarnaev brothers — all involved cell users
-
Identifying Moalin via the dragnet likely would have been impossible if NSA didn’t have access to T-Mobile cell data The phone dragnet orders specifically included cell phone identifiers starting in 2008 Also since 2008, phone dragnet orders seem to explicitly allow contact-chaining on cell identifiers, and several of the tools they use with phone dragnet data specifically pertain to cell phones

Now you don’t have to take my word for it. Here’s what Keith Alexander had to say about the claim Friday: Responding to a question about recent reports that the NSA collects data on only 20% to 30% of calls involving U.S. numbers, Alexander acknowledged that the agency doesn’t have full coverage of those calls. He wouldn’t say what fraction of the calls NSA gets information on, but specifically denied that the agency is completely missing data on calls made with cell phones. “That part is not true,” he said. “We don’t get it all. We don’t get 100% of the data. It’s not where we want it to be, but it has been sufficient to go after the key targets that we’re going after.” [my emphasis] Admittedly, Alexander is not always entirely honest, so it’s possible he’s just trying to dissuade terrorists from using cellphones while the NSA isn’t tracking them. But he points to the same evidence I did — that NSA has gotten key targets who use cell phones.

There’s something else Alexander said that might better explain the slew of claims that it can’t collect cell phone data. The NSA director, who is expected to retire within weeks, indicated that some of the gaps in coverage are due to the fact that the NSA “paused any changes to the program” during the recent controversy and discussions about restructuring the effort. The NSA has paused changes to the program. This echoes WaPo and WSJ reports that crises (they cited both the 2009 and current crisis) delayed some work on integrating cell data, but suggests that NSA was already making changes when the Snowden leaks started.
