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.

For most of the past six weeks, the biggest story out of Silicon Valley was Apple’s battle with the FBI over a federal order to unlock the iPhone of a mass shooter. The company’s refusal touched off a searing debate over privacy and security in the digital age. But this morning, at a small office in Mountain View, California, three guys made the scope of that enormous debate look kinda small. Mountain View is home to WhatsApp, an online messaging service now owned by tech giant Facebook, that has grown into one of the world’s most important applications. More than a billion people trade messages, make phone calls, send photos, and swap videos using the service. This means that only Facebook itself runs a larger self-contained communications network. And today, the enigmatic founders of WhatsApp, Brian Acton and Jan Koum, together with a high-minded coder and cryptographer who goes by the pseudonym Moxie Marlinspike, revealed that the company has added end-to-end encryption to every form of communication on its service.

This means that if any group of people uses the latest version of WhatsApp—whether that group spans two people or ten—the service will encrypt all messages, phone calls, photos, and videos moving among them. And that’s true on any phone that runs the app, from iPhones to Android phones to Windows phones to old school Nokia flip phones. With end-to-end encryption in place, not even WhatsApp’s employees can read the data that’s sent across its network. In other words, WhatsApp has no way of complying with a court order demanding access to the content of any message, phone call, photo, or video traveling through its service. Like Apple, WhatsApp is, in practice, stonewalling the federal government, but it’s doing so on a larger front—one that spans roughly a billion devices.

The FBI and the Justice Department declined to comment for this story. But many inside the government and out are sure to take issue with the company’s move. In late 2014, WhatsApp encrypted a portion of its network. In the months since, its service has apparently been used to facilitate criminal acts, including the terrorist attacks on Paris last year. According to The New York Times, as recently as this month, the Justice Department was considering a court case against the company after a wiretap order (still under seal) ran into WhatsApp’s end-to-end encryption. “The government doesn’t want to stop encryption,” says Joseph DeMarco, a former federal prosecutor who specializes in cybercrime and has represented various law enforcement agencies backing the Justice Department and the FBI in their battle with Apple. “But the question is: what do you do when a company creates an encryption system that makes it impossible for court-authorized search warrants to be executed? What is the reasonable level of assistance you should ask from that company?”

Throughout the past ten years, the FBI has at varying points in time maintained a particularly close relationship with Best Buy officials and used the company’s Geek Squad employees as informants. But the FBI refuses to confirm or deny key information about how the agency may potentially circumvent computer owners’ Fourth Amendment rights. The Electronic Frontier Foundation (EFF) obtained a handful of documents in response to a Freedom of Information Act (FOIA) lawsuit filed in February of last year. EFF says they show the relationship between the FBI and Geek Squad employees is much “cozier” than they thought.

In court filings, the defense mentioned there were “eight FBI informants at Geek Squad City” from 2007 to 2012. Multiple employees received payments ranging from $500-1000 for work as informants.

There is no evidence that FBI obtained warrants before the Geek Squad informants searched computers they were repairing. It is believed Geek Squad employees routinely search unallocated space for any illegal content that may be on a device and then alert the FBI after conducting “fishing expeditions” for criminal activity, and this is what the FBI trains them to do. EFF sought “records about the extent to which [the FBI] directs and trains Best Buy employees to conduct warrantless searches of people’s devices.” As is clear, the government stonewalled EFF and only released documents that were already referred to by news media. The FBI neither confirmed nor denied whether the agency has “similar relationships with other computer repair facilities or businesses.” The FBI also would not produce any documents that detailed procedures or “training materials” for cultivating informants at computer repair facilities.

It finally happened. The feds forced an Apple iPhone X owner to unlock their device with their face.A child abuse investigation unearthed by Forbes includes the first known case in which law enforcement used Apple Face ID facial recognition technology to open a suspect's iPhone. That's by any police agency anywhere in the world, not just in America.It happened on August 10, when the FBI searched the house of 28-year-old Grant Michalski, a Columbus, Ohio, resident who would later that month be charged with receiving and possessing child pornography. With a search warrant in hand, a federal investigator told Michalski to put his face in front of the phone, which he duly did. That allowed the agent to pick through the suspect's online chats, photos and whatever else he deemed worthy of investigation.The case marks another significant moment in the ongoing battle between law enforcement and tech providers, with the former trying to break the myriad security protections put in place by the latter. Since the fight between the world's most valuable company and the FBI in San Bernardino over access to an iPhone in 2016, Forbes has been tracking the various ways cops have been trying to break Apple's protections.

These and other classified documents provided by former NSA contractor Edward Snowden reveal that the NSA has developed technology not just to record and transcribe private conversations but to automatically identify the speakers. Americans most regularly encounter this technology, known as speaker recognition, or speaker identification, when they wake up Amazon’s Alexa or call their bank. But a decade before voice commands like “Hello Siri” and “OK Google” became common household phrases, the NSA was using speaker recognition to monitor terrorists, politicians, drug lords, spies, and even agency employees. The technology works by analyzing the physical and behavioral features that make each person’s voice distinctive, such as the pitch, shape of the mouth, and length of the larynx. An algorithm then creates a dynamic computer model of the individual’s vocal characteristics. This is what’s popularly referred to as a “voiceprint.” The entire process — capturing a few spoken words, turning those words into a voiceprint, and comparing that representation to other “voiceprints” already stored in the database — can happen almost instantaneously. Although the NSA is known to rely on finger and face prints to identify targets, voiceprints, according to a 2008 agency document, are “where NSA reigns supreme.” It’s not difficult to see why. By intercepting and recording millions of overseas telephone conversations, video teleconferences, and internet calls — in addition to capturing, with or without warrants, the domestic conversations of Americans — the NSA has built an unrivaled collection of distinct voices. Documents from the Snowden archive reveal that analysts fed some of these recordings to speaker recognition algorithms that could connect individuals to their past utterances, even when they had used unknown phone numbers, secret code words, or multiple languages.

The classified documents, dating from 2004 to 2012, show the NSA refining increasingly sophisticated iterations of its speaker recognition technology. They confirm the uses of speaker recognition in counterterrorism operations and overseas drug busts. And they suggest that the agency planned to deploy the technology not just to retroactively identify spies like Pelton but to prevent whistleblowers like Snowden.

Four of the country's largest cellular providers have been selling your real-time location information, allowing a Texas-based prison technology company, Securus, to track any phone "within seconds," without a warrant.  The system uses data sold by AT&T, Sprint, T-Mobile, Verizon and other carriers - who provide it through an intermediary called LocationSmart.  The service can find the whereabouts of almost any cellphone in the country within seconds. It does this by going through a system typically used by marketers and other companies to get location data from major cellphone carriers, including AT&T, Sprint, T-Mobile and Verizon, documents show. -New York Times Last week Sen. Ron Wyden (D-OR) sent a letter to the FCC demanding an investigation into Securus, after the New York Times revealed that former Mississippi County sheriff Cory Hutcheson used the service almost a dozen time to track the phones of other officers, and even targeted a judge. 

he National Security Agency (NSA) collected over 530 million phone records of Americans in 2017—that's three times the amount the spy agency sucked up in 2016. The figures were released Friday in an annual report from the Office of the Director of National Intelligence (ODNI). It shows that the number of "call detail records" the agency collected from telecommunications providers during Trump's first year in office was 534 million, compared to 151 million the year prior. "The intelligence community's transparency has yet to extend to explaining dramatic increases in their collection," said Robyn Greene, policy counsel at the Open Technology Institute. The content of the calls itself is not collected but so-called "metadata," which, as Gizmodo notes, "is supposedly anonymous, but it can easily be used to identify an individual. The information can also be paired with other publicly available information from social media and other sources to paint a surprisingly detailed picture of a person's life." The report also revealed that the agency, using its controversial Section 702 authority, increased the number of foreign targets of warrantless surveillance. It was 129,080 in 2017 compared to 106,469 in 2016. As digital rights group EFF noted earlier this year, Under Section 702, the NSA collects billions of communications, including those belonging to innocent Americans who are not actually targeted. These communications are then placed in databases that other intelligence and law enforcement agencies can access—for purposes unrelated to national security—without a warrant or any judicial review. "Overall," Jake Laperruque, senior counsel at the Project On Government Oversight, said to ZDNet, "the numbers show that the scale of warrantless surveillance is growing at a significant rate, but ODNI still won't tell Americans how much it affects them."

A company by the name of LocationSmart isn't having a particularly good month. The company recently received all the wrong kind of attention when it was caught up in a privacy scandal involving the nation's wireless carriers and our biggest prison phone monopoly. Like countless other companies and governments, LocationSmart buys your wireless location data from cell carriers. It then sells access to that data via a portal that can provide real-time access to a user's location via a tailored graphical interface using just the target's phone number.

Theoretically, this functionality is sold under the pretense that the tool can be used to track things like drug offenders who have skipped out of rehab. And ideally, all the companies involved were supposed to ensure that data lookup requests were accompanied by something vaguely resembling official documentation. But a recent deep dive by the New York Times noted how the system was open to routine abuse by law enforcement, after a Missouri Sherrif used the system to routinely spy on Judges and fellow law enforcement officers without much legitimate justification (or pesky warrants): "The service can find the whereabouts of almost any cellphone in the country within seconds. It does this by going through a system typically used by marketers and other companies to get location data from major cellphone carriers, including AT&T, Sprint, T-Mobile and Verizon, documents show. Between 2014 and 2017, the sheriff, Cory Hutcheson, used the service at least 11 times, prosecutors said. His alleged targets included a judge and members of the State Highway Patrol. Mr. Hutcheson, who was dismissed last year in an unrelated matter, has pleaded not guilty in the surveillance cases." It was yet another example of the way nonexistent to lax consumer privacy laws in the States (especially for wireless carriers) routinely come back to bite us. But then things got worse.

Driven by curiousity in the wake of the Times report, a PhD student at Carnegie Mellon University by the name of Robert Xiao discovered that the "try before you buy" system used by LocationSmart to advertise the cell location tracking system contained a bug, A bug so bad that it exposed the data of roughly 200 million wireless subscribers across the United States and Canada (read: nearly everybody). As we see all too often, the researcher highlighted how the security standards in place to safeguard this data were virtually nonexistent: "Due to a very elementary bug in the website, you can just skip that consent part and go straight to the location," said Robert Xiao, a PhD student at the Human-Computer Interaction Institute at Carnegie Mellon University, in a phone call. "The implication of this is that LocationSmart never required consent in the first place," he said. "There seems to be no security oversight here."

The digital privacy world was rocked late Thursday evening when The New York Times reported on Securus, a prison telecom company that has a service enabling law enforcement officers to locate most American cell phones within seconds. The company does this via a basic Web interface leveraging a location API—creating a way to effectively access a massive real-time database of cell-site records. Securus’ location ability relies on other data brokers and location aggregators that obtain that information directly from mobile providers, usually for the purposes of providing some commercial service like an opt-in product discount triggered by being near a certain location. ("You’re near a Carl’s Jr.! Stop in now for a free order of fries with purchase!") The Texas-based Securus reportedly gets its data from 3CInteractive, which in turn buys data from LocationSmart. Ars reached 3CInteractive's general counsel, Scott Elk, who referred us to a spokesperson. The spokesperson did not immediately respond to our query. But currently, anyone can get a sense of the power of a location API by trying out a demo from LocationSmart itself. Currently, the Supreme Court is set to rule on the case of Carpenter v. United States, which asks whether police can obtain more than 120 days' worth of cell-site location information of a criminal suspect without a warrant. In that case, as is common in many investigations, law enforcement presented a cell provider with a court order to obtain such historical data. But the ability to obtain real-time location data that Securus reportedly offers skips that entire process, and it's potentially far more invasive. Securus’ location service as used by law enforcement is also currently being scrutinized. The service is at the heart of an ongoing federal prosecution of a former Missouri sheriff’s deputy who allegedly used it at least 11 times against a judge and other law enforcement officers. On Friday, Sen. Ron Wyden (D-Ore.) publicly released his formal letters to AT&T and also to the Federal Communications Commission demanding detailed answers regarding these Securus revelations.

The White House and U.S. intelligence chiefs Wednesday backed making permanent a law that allows for the collection of digital communications of foreigners overseas, escalating a fight in Congress over privacy and security. The law, enshrined in Section 702 of the Foreign Intelligence Surveillance Act, is due to expire on December 31 unless Congress votes to reauthorize it, but is considered vital by U.S. intelligence agencies. Privacy advocates have criticized the law though for allowing the incidental collection of data belonging to millions of Americans without a search warrant. The push to make the law permanent may lead to a contentious debate over renewal of Section 702 in Congress, where lawmakers in both parties are deeply divided over whether to adopt transparency and oversight reforms

Reuters reported in March that the Trump administration supported renewal of Section 702 without any changes, citing an unnamed White House official, but it was not clear at the time whether it wanted the law made permanent.

On Feb. 5, 2021, the United Kingdom (U.K.) Supreme Court issued its judgment in R (on the application of KBR, Inc) v. Director of the Serious Fraud Office, holding that the U.K. Serious Fraud Office (SFO) lacked statutory authority to compel a U.S. company to disclose overseas data under threat of criminal sanction.  This judgment has obvious similarities with the so-called Microsoft Ireland decision of the U.S. Second Circuit Court of Appeals, which held that using U.S. Stored Communication Act (SCA) warrants to reach overseas data was an impermissible extraterritorial application of that legislation.  Microsoft Ireland was viewed by many as hugely controversial, hindering U.S. law enforcement’s access to overseas data, leading to a Supreme Court appeal and, ultimately, legislative amendments.  This new U.K. judgment promises to have an equally significant impact across the Atlantic on equivalent U.K. law enforcement powers.
