The first (and thus far only) roll-back of post-9/11 surveillance authorities was implemented over the weekend: The National Security Agency shuttered its program for collecting and holding the metadata of Americans’ phone calls under Section 215 of the Patriot Act. While bulk collection under Section 215 has ended, the government can obtain access to this information under the procedures specified in the USA Freedom Act. Indeed, some experts have argued that the Agency likely has access to more metadata because its earlier dragnet didn’t cover cell phones or Internet calling. In addition, the metadata of calls made by an individual in the United States to someone overseas and vice versa can still be collected in bulk — this takes place abroad under Executive Order 12333. No doubt the NSA wishes that this was the end of the surveillance reform story and the Paris attacks initially gave them an opening. John Brennan, the Director of the CIA, implied that the attacks were somehow related to “hand wringing” about spying and Sen. Tom Cotton (R-Ark.) introduced a bill to delay the shut down of the 215 program. Opponents of encryption were quick to say: “I told you so.”

But the facts that have emerged thus far tell a different story. It appears that much of the planning took place IRL (that’s “in real life” for those of you who don’t have teenagers). The attackers, several of whom were on law enforcement’s radar, communicated openly over the Internet. If France ever has a 9/11 Commission-type inquiry, it could well conclude that the Paris attacks were a failure of the intelligence agencies rather than a failure of intelligence authorities. Despite the passage of the USA Freedom Act, US surveillance authorities have remained largely intact. Section 702 of the FISA Amendments Act — which is the basis of programs like PRISM and the NSA’s Upstream collection of information from Internet cables — sunsets in the summer of 2017. While it’s difficult to predict the political environment that far out, meaningful reform of Section 702 faces significant obstacles. Unlike the Section 215 program, which was clearly aimed at Americans, Section 702 is supposedly targeted at foreigners and only picks up information about Americans “incidentally.” The NSA has refused to provide an estimate of how many Americans’ information it collects under Section 702, despite repeated requests from lawmakers and most recently a large cohort of advocates. The Section 215 program was held illegal by two federal courts (here and here), but civil attempts to challenge Section 702 have run into standing barriers. Finally, while two review panels concluded that the Section 215 program provided little counterterrorism benefit (here and here), they found that the Section 702 program had been useful.

There is, nonetheless, some pressure to narrow the reach of Section 702. The recent decision by the European Court of Justice in the safe harbor case suggests that data flows between Europe and the US may be restricted unless the PRISM program is modified to protect the information of Europeans (see here, here, and here for discussion of the decision and reform options). Pressure from Internet companies whose business is suffering — estimates run to the tune of $35 to 180 billion — as a result of disclosures about NSA spying may also nudge lawmakers towards reform. One of the courts currently considering criminal cases which rely on evidence derived from Section 702 surveillance may hold the program unconstitutional either on the basis of the Fourth Amendment or Article III for the reasons set out in this Brennan Center report. A federal district court in Colorado recently rejected such a challenge, although as explained in Steve’s post, the decision did not seriously explore the issues. Further litigation in the European courts too could have an impact on the debate.

Less than a week after the attacks in Paris — while the public and policymakers were still reeling, and the investigation had barely gotten off the ground — Cy Vance, Manhattan’s District Attorney, released a policy paper calling for legislation requiring companies to provide the government with backdoor access to their smartphones and other mobile devices. This is the first concrete proposal of this type since September 2014, when FBI Director James Comey reignited the “Crypto Wars” in response to Apple’s and Google’s decisions to use default encryption on their smartphones. Though Comey seized on Apple’s and Google’s decisions to encrypt their devices by default, his concerns are primarily related to end-to-end encryption, which protects communications that are in transit. Vance’s proposal, on the other hand, is only concerned with device encryption, which protects data stored on phones. It is still unclear whether encryption played any role in the Paris attacks, though we do know that the attackers were using unencrypted SMS text messages on the night of the attack, and that some of them were even known to intelligence agencies and had previously been under surveillance. But regardless of whether encryption was used at some point during the planning of the attacks, as I lay out below, prohibiting companies from selling encrypted devices would not prevent criminals or terrorists from being able to access unbreakable encryption. Vance’s primary complaint is that Apple’s and Google’s decisions to provide their customers with more secure devices through encryption interferes with criminal investigations. He claims encryption prevents law enforcement from accessing stored data like iMessages, photos and videos, Internet search histories, and third party app data. He makes several arguments to justify his proposal to build backdoors into encrypted smartphones, but none of them hold water.

Before addressing the major privacy, security, and implementation concerns that his proposal raises, it is worth noting that while an increase in use of fully encrypted devices could interfere with some law enforcement investigations, it will help prevent far more crimes — especially smartphone theft, and the consequent potential for identity theft. According to Consumer Reports, in 2014 there were more than two million victims of smartphone theft, and nearly two-thirds of all smartphone users either took no steps to secure their phones or their data or failed to implement passcode access for their phones. Default encryption could reduce instances of theft because perpetrators would no longer be able to break into the phone to steal the data.

Vance argues that creating a weakness in encryption to allow law enforcement to access data stored on devices does not raise serious concerns for security and privacy, since in order to exploit the vulnerability one would need access to the actual device. He considers this an acceptable risk, claiming it would not be the same as creating a widespread vulnerability in encryption protecting communications in transit (like emails), and that it would be cheap and easy for companies to implement. But Vance seems to be underestimating the risks involved with his plan. It is increasingly important that smartphones and other devices are protected by the strongest encryption possible. Our devices and the apps on them contain astonishing amounts of personal information, so much that an unprecedented level of harm could be caused if a smartphone or device with an exploitable vulnerability is stolen, not least in the forms of identity fraud and credit card theft. We bank on our phones, and have access to credit card payments with services like Apple Pay. Our contact lists are stored on our phones, including phone numbers, emails, social media accounts, and addresses. Passwords are often stored on people’s phones. And phones and apps are often full of personal details about their lives, from food diaries to logs of favorite places to personal photographs. Symantec conducted a study, where the company spread 50 “lost” phones in public to see what people who picked up the phones would do with them. The company found that 95 percent of those people tried to access the phone, and while nearly 90 percent tried to access private information stored on the phone or in other private accounts such as banking services and email, only 50 percent attempted contacting the owner.

With only days left to act and Rand Paul threatening a filibuster, Senate Republicans remain deeply divided over the future of the PATRIOT Act and have no clear path to keep key government spying authorities from expiring at the end of the month. Crucial parts of the PATRIOT Act, including a provision authorizing the government’s controversial bulk collection of American phone records, first revealed by Edward Snowden, are due to lapse May 31. That means Congress has barely a week to figure out a fix before before lawmakers leave town for Memorial Day recess at the end of the next week. Story Continued Below The prospects of a deal look grim: Senate Majority Leader Mitch McConnell on Thursday night proposed just a two-month extension of expiring PATRIOT Act provisions to give the two sides more time to negotiate, but even that was immediately dismissed by critics of the program.

The NSA and Britain's GCHQ hacked the world's biggest SIM card maker to harvest the encryption keys needed to silently and effortlessly eavesdrop on potentially millions of people. That's according to documents obtained by surveillance whistleblower Edward Snowden and leaked to the web on Thursday. "Wow. This is huge – it's one of the most significant findings of the Snowden files so far," computer security guru Bruce Schneier told The Register this afternoon. "We always knew that they would occasionally steal SIM keys. But all of them? The odds that they just attacked this one firm are extraordinarily low and we know the NSA does like to steal keys where it can." The damning slides, published by Snowden's chums at The Intercept, detail the activities of the as-yet unheard-of Mobile Handset Exploitation Team (MHET), run by the US and UK. The group targeted Gemalto, which churns out about two billion SIM cards each year for use around the world, and targeted it in an operation dubbed DAPINO GAMMA.

Gemalto's hacking may also bring into question some of its other security products as well. The company supplies chips for electronic passports issued by the US, Singapore, India, and many European states, and is also involved in the NFC and mobile banking sector. It's important to note that this is useful for tracking the phone activity of a target, but the mobile user can still use encryption on the handset itself to ensure that some communications remain private. "Ironically one of your best defenses against a hijacked SIM is to use software encryption," Jon Callas, CTO of encrypted chat biz Silent Circle told The Register. "In our case there's a TCP/IP cloud between Alice and Bob and that can deal with compromised routers along the path as well as SIM issues, and the same applies to similar mobile software."

On Wednesday the UK government admitted that its intelligence agencies had in fact broken the ECHR when spying on communications between lawyers and those suing the British state, so GCHQ might want to reconsider that statement.
