This week the Center for Media Justice, ColorOfChange.org, and New America’s Open Technology Institute filed a complaint with the Federal Communications Commission alleging the Baltimore police are violating the federal Communications Act by using cell site simulators, also known as Stingrays, that disrupt cellphone calls and interfere with the cellular network—and are doing so in a way that has a disproportionate impact on communities of color. Stingrays operate by mimicking a cell tower and directing all cellphones in a given area to route communications through the Stingray instead of the nearby tower. They are especially pernicious surveillance tools because they collect information on every single phone in a given area—not just the suspect’s phone—this means they allow the police to conduct indiscriminate, dragnet searches. They are also able to locate people inside traditionally-protected private spaces like homes, doctors’ offices, or places of worship. Stingrays can also be configured to capture the content of communications. Because Stingrays operate on the same spectrum as cellular networks but are not actually transmitting communications the way a cell tower would, they interfere with cell phone communications within as much as a 500 meter radius of the device (Baltimore’s devices may be limited to 200 meters). This means that any important phone call placed or text message sent within that radius may not get through. As the complaint notes, “[d]epending on the nature of an emergency, it may be urgently necessary for a caller to reach, for example, a parent or child, doctor, psychiatrist, school, hospital, poison control center, or suicide prevention hotline.” But these and even 911 calls could be blocked.

The Baltimore Police Department could be among the most prolific users of cell site simulator technology in the country. A Baltimore detective testified last year that the BPD used Stingrays 4,300 times between 2007 and 2015. Like other law enforcement agencies, Baltimore has used its devices for major and minor crimes—everything from trying to locate a man who had kidnapped two small children to trying to find another man who took his wife’s cellphone during an argument (and later returned it). According to logs obtained by USA Today, the Baltimore PD also used its Stingrays to locate witnesses, to investigate unarmed robberies, and for mysterious “other” purposes. And like other law enforcement agencies, the Baltimore PD has regularly withheld information about Stingrays from defense attorneys, judges, and the public. Moreover, according to the FCC complaint, the Baltimore PD’s use of Stingrays disproportionately impacts African American communities. Coming on the heels of a scathing Department of Justice report finding “BPD engages in a pattern or practice of conduct that violates the Constitution or federal law,” this may not be surprising, but it still should be shocking. The DOJ’s investigation found that BPD not only regularly makes unconstitutional stops and arrests and uses excessive force within African-American communities but also retaliates against people for constitutionally protected expression, and uses enforcement strategies that produce “severe and unjustified disparities in the rates of stops, searches and arrests of African Americans.”

Adding Stingrays to this mix means that these same communities are subject to more surveillance that chills speech and are less able to make 911 and other emergency calls than communities where the police aren’t regularly using Stingrays. A map included in the FCC complaint shows exactly how this is impacting Baltimore’s African-American communities. It plots hundreds of addresses where USA Today discovered BPD was using Stingrays over a map of Baltimore’s black population based on 2010 Census data included in the DOJ’s recent report:

Nearly three years after NSA whistleblower Edward Snowden gave journalists his trove of documents on the intelligence community’s broad and powerful surveillance regime, the public is still missing some crucial, basic facts about how the operations work. Surveillance researchers and privacy advocates published a report on Wednesday outlining what we do know, thanks to the period of discovery post-Snowden — and the overwhelming amount of things we don’t. The NSA’s domestic surveillance was understandably the initial focus of public debate. But that debate never really moved on to examine the NSA’s vastly bigger foreign operations. “There has been relatively little public or congressional debate within the United States about the NSA’s overseas surveillance operations,” write Faiza Patel and Elizabeth Goitein, co-directors of the Brennan Center for Justice’s Liberty and National Security Program, and Amos Toh, legal adviser for David Kaye, the U.N. special rapporteur on the right to freedom of opinion and expression.

The central guidelines the NSA is supposed to follow while spying abroad are described in Executive Order 12333, issued by President Ronald Reagan in 1981, which the authors describe as “a black box.” Just Security, a national security law blog, and the Brennan Center for Justice are co-hosting a panel on Thursday on Capitol Hill to discuss the policy, where the NSA’s privacy and civil liberties officer, Rebecca Richards, will be present. And the independent government watchdog, the Privacy and Civil Liberties Oversight Board, which has authored in-depth reports on other NSA programs, intends to publish a report on 12333 surveillance programs “this year,” according to spokesperson Jen Burita. In the meantime, the authors of the report came up with a list of questions they say need to be answered to create an informed public debate.

The United States and its key intelligence allies are quietly working behind the scenes to kneecap a mounting movement in the United Nations to promote a universal human right to online privacy, according to diplomatic sources and an internal American government document obtained by The Cable. The diplomatic battle is playing out in an obscure U.N. General Assembly committee that is considering a proposal by Brazil and Germany to place constraints on unchecked internet surveillance by the National Security Agency and other foreign intelligence services. American representatives have made it clear that they won't tolerate such checks on their global surveillance network. The stakes are high, particularly in Washington -- which is seeking to contain an international backlash against NSA spying -- and in Brasilia, where Brazilian President Dilma Roussef is personally involved in monitoring the U.N. negotiations.

The Brazilian and German initiative seeks to apply the right to privacy, which is enshrined in the International Covenant on Civil and Political Rights (ICCPR), to online communications. Their proposal, first revealed by The Cable, affirms a "right to privacy that is not to be subjected to arbitrary or unlawful interference with their privacy, family, home, or correspondence." It notes that while public safety may "justify the gathering and protection of certain sensitive information," nations "must ensure full compliance" with international human rights laws. A final version the text is scheduled to be presented to U.N. members on Wednesday evening and the resolution is expected to be adopted next week. A draft of the resolution, which was obtained by The Cable, calls on states to "to respect and protect the right to privacy," asserting that the "same rights that people have offline must also be protected online, including the right to privacy." It also requests the U.N. high commissioner for human rights, Navi Pillay, present the U.N. General Assembly next year with a report on the protection and promotion of the right to privacy, a provision that will ensure the issue remains on the front burner.

Publicly, U.S. representatives say they're open to an affirmation of privacy rights. "The United States takes very seriously our international legal obligations, including those under the International Covenant on Civil and Political Rights," Kurtis Cooper, a spokesman for the U.S. mission to the United Nations, said in an email. "We have been actively and constructively negotiating to ensure that the resolution promotes human rights and is consistent with those obligations." But privately, American diplomats are pushing hard to kill a provision of the Brazilian and German draft which states that "extraterritorial surveillance" and mass interception of communications, personal information, and metadata may constitute a violation of human rights. The United States and its allies, according to diplomats, outside observers, and documents, contend that the Covenant on Civil and Political Rights does not apply to foreign espionage.

Huge volumes of private emails, phone calls, and internet chats are being intercepted by the National Security Agency with the secret cooperation of more foreign governments than previously known, according to newly disclosed documents from whistleblower Edward Snowden. The classified files, revealed today by the Danish newspaper Dagbladet Information in a reporting collaboration with The Intercept, shed light on how the NSA’s surveillance of global communications has expanded under a clandestine program, known as RAMPART-A, that depends on the participation of a growing network of intelligence agencies.

It has already been widely reported that the NSA works closely with eavesdropping agencies in the United Kingdom, Canada, New Zealand, and Australia as part of the so-called Five Eyes surveillance alliance. But the latest Snowden documents show that a number of other countries, described by the NSA as “third-party partners,” are playing an increasingly important role – by secretly allowing the NSA to install surveillance equipment on their fiber-optic cables. The NSA documents state that under RAMPART-A, foreign partners “provide access to cables and host U.S. equipment.” This allows the agency to covertly tap into “congestion points around the world” where it says it can intercept the content of phone calls, faxes, e-mails, internet chats, data from virtual private networks, and calls made using Voice over IP software like Skype.

The program, which the secret files show cost U.S. taxpayers about $170 million between 2011 and 2013, sweeps up a vast amount of communications at lightning speed. According to the intelligence community’s classified “Black Budget” for 2013, RAMPART-A enables the NSA to tap into three terabits of data every second as the data flows across the compromised cables – the equivalent of being able to download about 5,400 uncompressed high-definition movies every minute. In an emailed statement, the NSA declined to comment on the RAMPART-A program. “The fact that the U.S. government works with other nations, under specific and regulated conditions, mutually strengthens the security of all,” said NSA spokeswoman Vanee’ Vines. “NSA’s efforts are focused on ensuring the protection of the national security of the United States, its citizens, and our allies through the pursuit of valid foreign intelligence targets only.”

The nonprofit advocacy group said it sent a letter to Christine Varney, Assistant Attorney General for Antitrust Division, after news that the European Commission had received three complaints against Google alleging the company manipulated search engine results in an anticompetitive way.

"As part of your continued antitrust investigation we call on you to shine a light on Google’s black box, and require it to explain what’s behind search results," Simpson wrote.

"If, as it appears, Google is tweaking results to further its narrow agenda, this anticompetitive behavior must be stopped."

Because HTML 4.0 essentially was a "frozen" version, the specific mechanism for displaying content has been very much format dependent (e.g., Apple QuickTime Movies and Flash video) and usually relies upon tags with varying parameters for passing the relevant information to the server. As a result, video and audio embedding on web pages has become something of a black art . Its perhaps not surprising then that the <audio> and <video> tags were among the first features to be added to the HTML 5 specification, and these seem to be the first elements of the HTML 5 specification that browser vendors implemented. These particular elements are intended to enable the browser to work with both types of media in an easy-to-use manner. An included support API gives users finer-grained control.

Theoretically, the <video> and <audio> elements should be able to handle most of the codecs currently in use. In practice, however, the browsers that do currently support these elements do so only for the open source Ogg Vorbis and Theora standards.

Yahoo Chief Information Security Officer Alex Stamos announced today at Black Hat 2014 that starting in the fall of this year, the purple-hued company will begin giving users the option of seamlessly wrapping their e-mails in PGP encryption. According to Kashmir Hill at Forbes, the encryption capability will be offered through a modified version of the same End-to-End browser plug-in that Google uses for PGP in Gmail. The announcement was tweeted by Yan Zhu, who has reportedly been hired by Yahoo to adapt End-to-End for use with Yahoo Mail. Zhu formerly worked as an engineer at the Electronic Frontier Foundation, an organization that has consistently been outspoken in its call for the widespread use of encryption throughout the Web and the Internet in general.

Security experts call it a “drive-by download”: a hacker infiltrates a high-traffic website and then subverts it to deliver malware to every single visitor. It’s one of the most powerful tools in the black hat arsenal, capable of delivering thousands of fresh victims into a hackers’ clutches within minutes. Now the technique is being adopted by a different kind of a hacker—the kind with a badge. For the last two years, the FBI has been quietly experimenting with drive-by hacks as a solution to one of law enforcement’s knottiest Internet problems: how to identify and prosecute users of criminal websites hiding behind the powerful Tor anonymity system. The approach has borne fruit—over a dozen alleged users of Tor-based child porn sites are now headed for trial as a result. But it’s also engendering controversy, with charges that the Justice Department has glossed over the bulk-hacking technique when describing it to judges, while concealing its use from defendants. Critics also worry about mission creep, the weakening of a technology relied on by human rights workers and activists, and the potential for innocent parties to wind up infected with government malware because they visited the wrong website. “This is such a big leap, there should have been congressional hearings about this,” says ACLU technologist Chris Soghoian, an expert on law enforcement’s use of hacking tools. “If Congress decides this is a technique that’s perfectly appropriate, maybe that’s OK. But let’s have an informed debate about it.”

The FBI’s use of malware is not new. The bureau calls the method an NIT, for “network investigative technique,” and the FBI has been using it since at least 2002 in cases ranging from computer hacking to bomb threats, child porn to extortion. Depending on the deployment, an NIT can be a bulky full-featured backdoor program that gives the government access to your files, location, web history and webcam for a month at a time, or a slim, fleeting wisp of code that sends the FBI your computer’s name and address, and then evaporates. What’s changed is the way the FBI uses its malware capability, deploying it as a driftnet instead of a fishing line. And the shift is a direct response to Tor, the powerful anonymity system endorsed by Edward Snowden and the State Department alike.

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.

In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce "export-grade" (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA "black budget" (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it's likely NSA has been breaking 1024-bit Diffie-Hellman for some time now. The good news is, in the time since this research was originally published, the major browser vendors (IE, Chrome, and Firefox) have removed support for 512-bit Diffie-Hellman, addressing the biggest vulnerability. However, 1024-bit Diffie-Hellman remains supported for the forseeable future despite its vulnerability to NSA surveillance. In this post, we present some practical tips to protect yourself from the surveillance machine, whether you're using a web browser, an SSH client, or VPN software.

Amazon’s face surveillance technology is the target of growing opposition nationwide, and today, there are 28 more causes for concern. In a test the ACLU recently conducted of the facial recognition tool, called “Rekognition,” the software incorrectly matched 28 members of Congress, identifying them as other people who have been arrested for a crime.  The members of Congress who were falsely matched with the mugshot database we used in the test include Republicans and Democrats, men and women, and legislators of all ages, from all across the country.

The false matches were disproportionately of people of color, including six members of the Congressional Black Caucus, among them civil rights legend Rep. John Lewis (D-Ga.). These results demonstrate why Congress should join the ACLU in calling for a moratorium on law enforcement use of face surveillance.
