The USA PATRIOT Act granted the government powerful new spying capabilities that have grown out of control—but the provision that the FBI and NSA have been using to collect the phone records of millions of innocent people expires on June 1. Tell Congress: it’s time to rethink out-of-control spying. A vote to reauthorize Section 215 is a vote against the Constitution.

On June 5, 2013, the Guardian published a secret court order showing that the NSA has interpreted Section 215 to mean that, with the help of the FBI, it can collect the private calling records of millions of innocent people. The government could even try to use Section 215 for bulk collection of financial records. The NSA’s defenders argue that invading our privacy is the only way to keep us safe. But the White House itself, along with the President’s Review Board has said that the government can accomplish its goals without bulk telephone records collection. And the Privacy and Civil Liberties Oversight Board said, “We have not identified a single instance involving a threat to the United States in which [bulk collection under Section 215 of the PATRIOT Act] made a concrete difference in the outcome of a counterterrorism investigation.” Since June of 2013, we’ve continued to learn more about how out of control the NSA is. But what has not happened since June is legislative reform of the NSA. There have been myriad bipartisan proposals in Congress—some authentic and some not—but lawmakers didn’t pass anything. We need comprehensive reform that addresses all the ways the NSA has overstepped its authority and provides the NSA with appropriate and constitutional tools to keep America safe. In the meantime, tell Congress to take a stand. A vote against reauthorization of Section 215 is a vote for the Constitution.

The nation’s top technology firms and a coalition of privacy groups are urging Congress to place curbs on government surveillance in the face of a fast-approaching deadline for legislative action. A set of key Patriot Act surveillance authorities expire June 1, but the effective date is May 21 — the last day before Congress breaks for a Memorial Day recess. In a letter to be sent Wednesday to the Obama administration and senior lawmakers, the coalition vowed to oppose any legislation that, among other things, does not ban the “bulk collection” of Americans’ phone records and other data.

We know that there are some in Congress who think that they can get away with reauthorizing the expiring provisions of the Patriot Act without any reforms at all,” said Kevin Bankston, policy director of New America Foundation’s Open Technology Institute, a privacy group that organized the effort. “This letter draws a line in the sand that makes clear that the privacy community and the Internet industry do not intend to let that happen without a fight.” At issue is the bulk collection of Americans’ data by intelligence agencies such as the National Security Agency. The NSA’s daily gathering of millions of records logging phone call times, lengths and other “metadata” stirred controversy when it was revealed in June 2013 by former NSA contractor Edward Snowden. The records are placed in a database that can, with a judge’s permission, be searched for links to foreign terrorists.They do not include the content of conversations.

That program, placed under federal surveillance court oversight in 2006, was authorized by the court in secret under Section 215 of the Patriot Act — one of the expiring provisions. The public outcry that ensued after the program was disclosed forced President Obama in January 2014 to call for an end to the NSA’s storage of the data. He also appealed to Congress to find a way to preserve the agency’s access to the data for counterterrorism information.

Many of the technologies, both military technologies and surveillance technologies, that are developed for purposes of policing the empire find their way back home and get repurposed. You saw this in Ferguson, where we had military equipment in the streets to police nonviolent civil unrest, and we’re seeing this with surveillance technologies, where things that are deployed for use in war zones are now commonly in the arsenals of local police departments. For example, a cellphone surveillance tool that we call the StingRay—which mimics a cellphone tower and communicates with all the phones around—was really developed as a military technology to help identify targets. Now, because it’s so inexpensive, and because there is a surplus of these things that are being developed, it ends up getting pushed down into local communities without local democratic consent or control.

Just as any new technology claims to offer the most advanced development; that their definition of progress will cure society’s ills or make life easier by eliminating the drudgery of antiquated appliances, the Wifi Alliance  was organized as a worldwide wireless network to connect ‘everyone and everything, everywhere” as it promised “improvements to nearly every aspect of daily life.”    The Alliance, which makes no pretense of potential health or environmental concerns, further proclaimed (and they may be correct) that there are “more wifi devices than people on earth”.   It is that inescapable exposure to ubiquitous wireless technologies wherein lies the problem.   

Even prior to the 1997 introduction of commercially available wifi devices which has saturated every industrialized country, EMF wifi hot spots were everywhere.  Today with the addition of cell and cordless phones and towers, broadcast antennas, smart meters and the pervasive computer wifi, both adults and especially vulnerable children are surrounded 24-7 by an inescapable presence with little recognition that all radiation exposure is cumulative.    

The National Toxicology Program (NTP), a branch of the US National Institute for Health (NIH), conducted the world’s largest study on radiofrequency radiation used by the US telecommunications industry and found a ‘significantly statistical increase in brain and heart cancers” in animals exposed to EMF (electromagnetic fields).  The NTP study confirmed the connection between mobile and wireless phone use and human brain cancer risks and its conclusions were supported by other epidemiological peer-reviewed studies.  Of special note is that studies citing the biological risk to human health were below accepted international exposure standards.    

“The intent is world domination,” Berners-Lee says with a wry smile. The British-born scientist is known for his dry sense of humor. But in this case, he is not joking.This week, Berners-Lee will launch Inrupt, a startup that he has been building, in stealth mode, for the past nine months. Backed by Glasswing Ventures, its mission is to turbocharge a broader movement afoot, among developers around the world, to decentralize the web and take back power from the forces that have profited from centralizing it. In other words, it’s game on for Facebook, Google, Amazon. For years now, Berners-Lee and other internet activists have been dreaming of a digital utopia where individuals control their own data and the internet remains free and open. But for Berners-Lee, the time for dreaming is over.

In a post published this weekend, Berners-Lee explains that he is taking a sabbatical from MIT to work full time on Inrupt. The company will be the first major commercial venture built off of Solid, a decentralized web platform he and others at MIT have spent years building.

f all goes as planned, Inrupt will be to Solid what Netscape once was for many first-time users of the web: an easy way in. And like with Netscape, Berners-Lee hopes Inrupt will be just the first of many companies to emerge from Solid.

Today, March 31st 2017, WikiLeaks releases Vault 7 "Marble" -- 676 source code files for the CIA's secret anti-forensic Marble Framework. Marble is used to hamper forensic investigators and anti-virus companies from attributing viruses, trojans and hacking attacks to the CIA. Marble does this by hiding ("obfuscating") text fragments used in CIA malware from visual inspection. This is the digital equivallent of a specalized CIA tool to place covers over the english language text on U.S. produced weapons systems before giving them to insurgents secretly backed by the CIA. Marble forms part of the CIA's anti-forensics approach and the CIA's Core Library of malware code. It is "[D]esigned to allow for flexible and easy-to-use obfuscation" as "string obfuscation algorithms (especially those that are unique) are often used to link malware to a specific developer or development shop." The Marble source code also includes a deobfuscator to reverse CIA text obfuscation. Combined with the revealed obfuscation techniques, a pattern or signature emerges which can assist forensic investigators attribute previous hacking attacks and viruses to the CIA. Marble was in use at the CIA during 2016. It reached 1.0 in 2015.

The source code shows that Marble has test examples not just in English but also in Chinese, Russian, Korean, Arabic and Farsi. This would permit a forensic attribution double game, for example by pretending that the spoken language of the malware creator was not American English, but Chinese, but then showing attempts to conceal the use of Chinese, drawing forensic investigators even more strongly to the wrong conclusion, --- but there are other possibilities, such as hiding fake error messages. The Marble Framework is used for obfuscation only and does not contain any vulnerabilties or exploits by itself.

Today we are releasing the implementation guide for EFF’s Do Not Track (DNT) policy. For years users have been able to set a Do Not Track signal in their browser, but there has been little guidance for websites as to how to honor that request. EFF’s DNT policy sets out a meaningful response for servers to follow, and this guide provides details about how to apply it in practice. At its core, DNT protects user privacy by excluding the use of unique identifiers for cross-site tracking, and by limiting the retention period of log data to ten days. This short retention period gives sites the time they need for debugging and security purposes, and to generate aggregate statistical data. From this baseline, the policy then allows exceptions when the user's interactions with the site—e.g., to post comments, make a purchase, or click on an ad—necessitates collecting more information. The site is then free to retain any data necessary to complete the transaction. We believe this approach balances users’ privacy expectations with the ability of websites to deliver the functionality users want. Websites often integrate third-party content and rely on third-party services (like content delivery networks or analytics), and this creates the potential for user data to be leaked despite the best intentions of the site operator. The guide identifies potential pitfalls and catalogs providers of compliant services. It is common, for example, to embed media from platforms like You Tube, Sound Cloud, and Twitter, all of which track users whenever their widgets are loaded. Fortunately, Embedly, which offers control over the appearance of embeds, also supports DNT via its API, displaying a poster instead and loading the widget only if the user clicks on it knowingly.

Knowledge makes the difference between willing tracking and non-consensual tracking. Users should be able to choose whether they want to give up their privacy in exchange for using a site or a  particular feature. This means sites need to be transparent about their practices. A great example of this is our biggest adopter, Medium, which does not track DNT users who browse the site and gives clear information about tracking to users when they choose to log in. This is their previous log-in panel, the DNT language is currently being added to their new interface.

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:

This is part of a Motherboard mini-series on the proliferation of phone cracking technology, the people behind it, and who is buying it. Follow along here.When cops have a phone to break into, they just might pull a small, laptop-sized device out of a rugged briefcase. After plugging the phone in with a cable, and a few taps of a touch-screen, the cops have now bypassed the phone’s passcode. Almost like magic, they now have access to call logs, text messages, and in some cases even deleted data.State police forces and highway patrols in the US have collectively spent millions of dollars on this sort of technology to break into and extract data from mobile phones, according to documents obtained by Motherboard. Over 2,000 pages of invoices, purchase orders, communications, and other documents lay out in unprecedented detail how one company in particular has cornered the trade in mobile phone forensics equipment across the United States.Cellebrite, an Israel-based firm, sells tools that can pull data from most mobile phones on the market, such as contact lists, emails, and wiped messages. Cellebrite's products can also circumvent the passcode locks or other security protections on many current mobile phones. The gear is typically used to gather evidence from a criminal suspect's device after it has been seized, and although not many public examples of abuse are available, Cellebrite’s tools have been used by non-US authorities to prosecute dissidents.Previous reports have focused on federal agencies' acquisition of Cellebrite tools. But as smartphones have proliferated and increasingly become the digital center of our lives, the demand and supply of mobile forensics tools has trickled down to more local bodies.

On the 21st floor of a high-rise hotel in Cleveland, in a room full of political operatives, Microsoft’s Research Division was advertising a technology that could read each facial expression in a massive crowd, analyze the emotions, and report back in real time. “You could use this at a Trump rally,” a sales representative told me. At both the Republican and Democratic conventions, Microsoft sponsored event spaces for the news outlet Politico. Politico, in turn, hosted a series of Microsoft-sponsored discussions about the use of data technology in political campaigns. And throughout Politico’s spaces in both Philadelphia and Cleveland, Microsoft advertised an array of products from “Microsoft Cognitive Services,” its artificial intelligence and cloud computing division. At one exhibit, titled “Realtime Crowd Insights,” a small camera scanned the room, while a monitor displayed the captured image. Every five seconds, a new image would appear with data annotated for each face — an assigned serial number, gender, estimated age, and any emotions detected in the facial expression. When I approached, the machine labeled me “b2ff” and correctly identified me as a 23-year-old male.

“Realtime Crowd Insights” is an Application Programming Interface (API), or a software tool that connects web applications to Microsoft’s cloud computing services. Through Microsoft’s emotional analysis API — a component of Realtime Crowd Insights — applications send an image to Microsoft’s servers. Microsoft’s servers then analyze the faces and return emotional profiles for each one. In a November blog post, Microsoft said that the emotional analysis could detect “anger, contempt, fear, disgust, happiness, neutral, sadness or surprise.” Microsoft’s sales representatives told me that political campaigns could use the technology to measure the emotional impact of different talking points — and political scientists could use it to study crowd response at rallies.

Facial recognition technology — the identification of faces by name — is already widely used in secret by law enforcement, sports stadiums, retail stores, and even churches, despite being of questionable legality. As early as 2002, facial recognition technology was used at the Super Bowl to cross-reference the 100,000 attendees to a database of the faces of known criminals. The technology is controversial enough that in 2013, Google tried to ban the use of facial recognition apps in its Google glass system. But “Realtime Crowd Insights” is not true facial recognition — it could not identify me by name, only as “b2ff.” It did, however, store enough data on each face that it could continuously identify it with the same serial number, even hours later. The display demonstrated that capability by distinguishing between the number of total faces it had seen, and the number of unique serial numbers. Photo: Alex Emmons

The movement to encrypt the web has reached a milestone. As of earlier this month, approximately half of Internet traffic is now protected by HTTPS. In other words, we are halfway to a web safer from the eavesdropping, content hijacking, cookie stealing, and censorship that HTTPS can protect against. Mozilla recently reported that the average volume of encrypted web traffic on Firefox now surpasses the average unencrypted volume

Google Chrome’s figures on HTTPS usage are consistent with that finding, showing that over 50% of of all pages loaded are protected by HTTPS across different operating systems.

This milestone is a combination of HTTPS implementation victories: from tech giants and large content providers, from small websites, and from users themselves.

The latest leaks from WikiLeaks' Vault 7 is titled “Dark Matter” and claims that the CIA has been bugging “factory fresh” iPhones since at least 2008 through suppliers.

And here is the full press release from WikiLeaks: Today, March 23rd 2017, WikiLeaks releases Vault 7 "Dark Matter", which contains documentation for several CIA projects that infect Apple Mac Computer firmware (meaning the infection persists even if the operating system is re-installed) developed by the CIA's Embedded Development Branch (EDB). These documents explain the techniques used by CIA to gain 'persistence' on Apple Mac devices, including Macs and iPhones and demonstrate their use of EFI/UEFI and firmware malware.   Among others, these documents reveal the "Sonic Screwdriver" project which, as explained by the CIA, is a "mechanism for executing code on peripheral devices while a Mac laptop or desktop is booting" allowing an attacker to boot its attack software for example from a USB stick "even when a firmware password is enabled". The CIA's "Sonic Screwdriver" infector is stored on the modified firmware of an Apple Thunderbolt-to-Ethernet adapter.   "DarkSeaSkies" is "an implant that persists in the EFI firmware of an Apple MacBook Air computer" and consists of "DarkMatter", "SeaPea" and "NightSkies", respectively EFI, kernel-space and user-space implants.   Documents on the "Triton" MacOSX malware, its infector "Dark Mallet" and its EFI-persistent version "DerStake" are also included in this release. While the DerStake1.4 manual released today dates to 2013, other Vault 7 documents show that as of 2016 the CIA continues to rely on and update these systems and is working on the production of DerStarke2.0.   Also included in this release is the manual for the CIA's "NightSkies 1.2" a "beacon/loader/implant tool" for the Apple iPhone. Noteworthy is that NightSkies had reached 1.2 by 2008, and is expressly designed to be physically installed onto factory fresh iPhones. i.e the CIA has been infecting the iPhone supply chain of its targets since at least 2008.   While CIA assets are sometimes used to physically infect systems in the custody of a target it is likely that many CIA physical access attacks have infected the targeted organization's supply chain including by interdicting mail orders and other shipments (opening, infecting, and resending) leaving the United States or otherwise.

One security start-up that had an encounter with the FBI was Wickr, a privacy-forward text messaging app for the iPhone with an Android version in private beta. Wickr's co-founder Nico Sell told CNET at Defcon, "Wickr has been approached by the FBI and asked for a backdoor. We said, 'No.'" The mistrust runs deep. "Even if [the NSA] stood up tomorrow and said that [they] have eliminated these programs," said Marlinspike, "How could we believe them? How can we believe that anything they say is true?" Where does security innovation go next? The immediate future of information security innovation most likely lies in software that provides an existing service but with heightened privacy protections, such as webmail that doesn't mine you for personal data.

Wickr's Sell thinks that her company has hit upon a privacy innovation that a few others are also doing, but many will soon follow: the company itself doesn't store user data. "[The FBI] would have to force us to build a new app. With the current app there's no way," she said, that they could incorporate backdoor access to Wickr users' texts or metadata. "Even if you trust the NSA 100 percent that they're going to use [your data] correctly," Sell said, "Do you trust that they're going to be able to keep it safe from hackers? What if somebody gets that database and posts it online?" To that end, she said, people will start seeing privacy innovation for services that don't currently provide it. Calling it "social networks 2.0," she said that social network competitors will arise that do a better job of protecting their customer's privacy and predicted that some that succeed will do so because of their emphasis on privacy. Abine's recent MaskMe browser add-on and mobile app for creating disposable e-mail addresses, phone numbers, and credit cards is another example of a service that doesn't have access to its own users' data.

Stamos predicted changes in services that companies with cloud storage offer, including offering customers the ability to store their data outside of the U.S. "If they want to stay competitive, they're going to have to," he said. But, he cautioned, "It's impossible to do a cloud-based ad supported service." Soghoian added, "The only way to keep a service running is to pay them money." This, he said, is going to give rise to a new wave of ad-free, privacy protective subscription services.

Do I need to buy minutes from Sprint or anyone else? No. We're the first-ever wireless provider to bundle WiFi calling with access to cellular whenever you need it. Depending on the plan you choose, your Republic Wireless phone will have unlimited* access to data, talk and text when using the Sprint cellular network. Note that the $5 plan offered by Republic is WiFi only and the $10 plan includes cellular talk and text (no data). All Republic plans include unlimited data, talk and text on WiFi. 

The Federal Communications Commission is poised to ruin the free Internet on a technicality. The group is expected to introduce new net neutrality laws that would allow companies to pay for better access to consumers through deals similar to the one struck by Netflix and Comcast earlier this year. The argument is that those deals don’t technically fall under the net neutrality umbrella, so these new rules won’t apply to them even though they directly affect the Internet. At least the commission is being upfront about its disinterest in protecting the free Internet.

The Verge notes that the proposed rules will offer some protections to consumers: The Federal Communication Commission’s proposal for new net neutrality rules will allow internet service providers to charge companies for preferential treatment, effectively undermining the concept of net neutrality, according to The Wall Street Journal. The rules will reportedly allow providers to charge for preferential treatment so long as they offer that treatment to all interested parties on “commercially reasonable” terms, with the FCC will deciding whether the terms are reasonable on a case-by-case basis. Providers will not be able to block individual websites, however. The goal of net neutrality rules is to prevent service providers from discriminating between different content, allowing all types of data and all companies’ data to be treated equally. While it appears that outright blocking of individual services won’t be allowed, the Journal reports that some forms of discrimination will be allowed, though that will apparently not include slowing down websites.

Re/code summarizes the discontent with these proposed rules: Consumer groups have complained about that plan because they’re worried that Wheeler’s rules may not hold up in court either. A federal appeals court rejected two previous versions of net neutrality rules after finding fault in the FCC’s legal reasoning. During the latest smackdown, however, the court suggested that the FCC had some authority to impose net neutrality rules under a section of the law that gives the agency the ability to regulate the deployment of broadband lines. Internet activists would prefer that the FCC just re-regulate Internet lines under old rules designed for telephone networks, which they say would give the agency clear authority to police Internet lines. Wheeler has rejected that approach for now. Phone and cable companies, including Comcast, AT&T and Verizon, have vociferously fought that idea over the past few years.

Some time on Tuesday afternoon, about 50,000 Comcast Internet customers in Houston will become part of a massive public Wi-Fi hotspot network, a number that will swell to 150,000 by the end of June. Comcast will begin activating a feature in its Arris Touchstone Telephony Wireless Gateway Modems that sets up a public Wi-Fi hotspot alongside a residential Internet customer’s private home network. Other Comcast customers will be able to log in to the hotspots for free using a computer, smartphone or other mobile device. And once they log into one, they’ll be automatically logged in to others when their devices “see” them. Comcast says the hotspot – which appears as “xfinitywifi” to those searching for a Wi-Fi connection – is completely separate from the home network. Someone accessing the Net through the hotspot can’t get to the computers, printers, mobile devices, streaming boxes and more sitting on the host network. Comcast officials also say that people using the Internet via the hotspot won’t slow down Internet access on the home network. Additional capacity is allotted to handle the bandwidth. You can read more about Comcast’s reason for doing this in my report on HoustonChronicle.com.

What’s interesting about this move is that, by default, the feature is being turned on without its subscribers’ prior consent. It’s an opt-out system – you have to take action to not participate. Comcast spokesman Michael Bybee said on Monday that notices about the hotspot feature were mailed to customers a few weeks ago, and email notifications will go out after it’s turned on. But it’s a good bet that this will take many Comcast customers by surprise. If you have one of these routers and don’t want to host a public Wi-Fi hotspot, here’s how to turn it off.

The additional capacity for public hotspot users is provided through a separate channel on the modem called a “service flow,” according to Comcast. But the speed of the connection reflects the tier of the subscriber hosting the hotspot. For example, if you connect to a hotspot hosted by a home user with a 25-Mbps connection, it will be slower than if you connect to a host system on the 50-Mbps tier.
