Microsoft Challenged A National Security Letter That Included A Gag Order And Won

Posted 1 hour ago by Alex Wilhelm (@alex)

Microsoft challenged a National Security Letter from the FBI last year – and won. The documents relating the case were recently unsealed, making the effort public.

The gist is simple: Microsoft received a National Security Letter requesting “basic subscriber information” regarding an “enterprise” customer. That’s how Microsoft characterized the request. For simplicity, the FBI was after the metadata of a large Microsoft client.

The letter banned Microsoft from disclosing to anyone that the data had been requested. Microsoft didn’t think that reasonable and filed a challenge. The FBI then retracted its request. The customer in question was an Office 365 user. The FBI wanted data involving “several categories of information regarding a single user account associated with the e-mail domain which is [redacted] supported within the block of individual Office 365 accounts [snip] provided to [redacted] by Microsoft under the Contract.”

On the heels of the passage of an NSA reform bill that likely fails at its stated task, and the failure of two amendments to a separate bill aimed at defunding certain government actions that weaken encryption and harm privacy, this is welcome news.

What’s fun in this isn’t that a single National Security Letter was beaten back, but more how Microsoft argued its case. A few excerpts that are worth noting, regarding why Microsoft felt the Letter wasn’t a legal request:
