Federal Magistrate Judge John M. Facciola denied a US government request earlier this month for a search and seizure warrant, targeting electronic data stored on Apple Inc. property. Facciola’s order, issued on March 7, 2014, rejected what it described as only the latest in a series of “overbroad search and seizure requests,” and “unconstitutional warrant applications” submitted by the US government to the US District Court for the District of Columbia. Facciola referred to the virtually unlimited warrant request submitted by the Justice Department as “repugnant to the Fourth Amendment.” The surveillance request sought information in relation to a “kickback investigation” of a defense contractor, details about which remain secret. It is significant, however, that the surveillance request denied by Facciola relates to a criminal investigation, unrelated to terrorism. This demonstrates that the use by the Obama administration of blanket warrants enabling them to seize all information on a person's Internet accounts is not limited to terrorism, as is frequently claimed, but is part of a program of general mass illegal spying on the American people.

Facciola’s ruling states in no uncertain terms that the Obama administration has aggressively and repeatedly sought expansive, unconstitutional warrants, ignoring the court’s insistence for specific, narrowly targeted surveillance requests. “The government continues to submit overly broad warrants and makes no effort to balance the law enforcement interest against the obvious expectation of privacy email account holders have in their communications…The government continues to ask for all electronically stored information in email accounts, irrespective of the relevance to the investigation,” wrote Judge Facciola. As stated in the ruling, the surveillance requests submitted to the court by the US government sought the following comprehensive, virtually limitless list of information about the target: “All records or other information stored by an individual using each account, including address books, contact and buddy lists, pictures, and files… All records or other information regarding the identification of the accounts, to include full name, physical address, telephone numbers and other identifies, records of session times and durations, the date on which each account was created, the length of service, the types of service utilized, the Internet Protocol (IP) address used to register each account, log-in IP addresses associated with session times and dates, account status, alternative email addresses provided during registration, methods of connecting, log files, and means of payment (including any credit or bank account number).”

Responding to these all-encompassing warrant requests, Judge Facciola ruled that evidence of probable cause was necessary for each specific item sought by the government. “This Court is increasingly concerned about the government’s applications for search warrants for electronic data. In essence, its applications ask for the entire universe of information tied to a particular account, even if it has established probable cause only for certain information,” Facciola wrote. “It is the Court’s duty to reject any applications for search warrants where the standard of probable cause has not been met… To follow the dictates of the Fourth Amendment and to avoid issuing a general warrant, a court must be careful to ensure that probable cause exists to seize each item specified in the warrant application… Any search of an electronic source has the potential to unearth tens or hundreds of thousands of individual documents, pictures, movies, or other constitutionally protected content.” Facciola also noted in the ruling that the government never reported the length of time it would keep the data, or whether it planned to destroy the data at any point.

The Intercept published an expose on the NSA's XKeyscore program. Along with information on the breadth and scale of the NSA's metadata collection, The Intercept revealed how the NSA relies on unencrypted cookie data to identify users. As The Intercept says: "The NSA’s ability to piggyback off of private companies’ tracking of their own users is a vital instrument that allows the agency to trace the data it collects to individual users. It makes no difference if visitors switch to public Wi-Fi networks or connect to VPNs to change their IP addresses: the tracking cookie will follow them around as long as they are using the same web browser and fail to clear their cookies." The NSA slides released by The Intercept give detailed guides to understanding the data transmitted by these cookies, as well as how to find unique machine identifiers that analysts can use to differentiate between multiple machines using the same IP address. We've written before about how spy agencies piggyback on social media account data to find Internet users' names or other identifying info, and these slides drive home the point that HTTP cookies leave users vulnerable to government surveillance, since any intermediary (or spy agency) can read the sensitive data they contain.

Worse yet, most of the time these identifying cookies come from third-party sources on webpages, and users have no meaningful way to opt out of receiving them (short of blocking all third party cookies) since advertisers (the main server of these types of cookies) refuse to honor the Do Not Track header.  Browser makers could help address this sort of non-consensual tracking by both advertisers and the NSA with some simple technical changes—changes that have been shown to reduce the number of third party cookies received by 67%. So far, though, they've been unwilling to build privacy protecting features in by default. Until they do, the best way for users to protect themselves is by installing a privacy protecting app like Privacy Badger, which is designed to block these types of uniquely identifying tracking cookies, or HTTPS Everywhere to block the transmission of HTTP cookies.
