The House of Representatives has passed the USA Freedom Act, which represents a significant down payment on broader government surveillance reform. We need as many people as possible speaking up to make sure that the Senate says YES to the USA Freedom Act.

Four months from now, at the same time that the National Security Agency finally abandons the massive domestic telephone dragnet exposed by whistleblower Edward Snowden, it will also stop perusing the vast archive of data collected by the program. The NSA announced on Monday that it will expunge all the telephone metadata it previously swept up, citing Section 215 of the U.S.A Patriot Act. The program was ruled illegal by a federal appeals court in May. In June, Congress voted to end the program, but gave the NSA until the end of November to phase it out. The historical metadata —  records of American phone calls showing who called who, when, and for how long — will be put out of the reach of analysts on November 29, although technical personnel will have access for three more months. The program started 14 years ago, and operated under rules requiring data be retained for five years, and then destroyed.

The only possible hold-up, ironically, would be if any of the civil lawsuits prompted by the program prohibit the destruction of the data. “The telephony metadata” will be “preserved solely because of preservation obligations in pending civil litigation,” the Office of the Director of National Intelligence announced. “As soon as possible, NSA will destroy the Section 215 bulk telephony metadata upon expiration of its litigation preservation obligations.” ACLU staff attorney Alex Abdo told The Intercept his organization is “pleased that the NSA intends to purge the call records it has collected illegally.” But, he added: “Even with today’s pledge, the devil may be in the details.”

Imagine you are the target of a phishing attack: Someone sends you an email attachment containing malware. Your email service provider shares the attachment with the government, so that others can configure their computer systems to spot similar attacks. The next day, your provider gets a call. It’s the Department of Homeland Security (DHS), and they’re curious. The malware appears to be from Turkey. Why, DHS wants to know, might someone in Turkey be interested in attacking you? So, would your email company please share all your emails with the government? Knowing more about you, investigators might better understand the attack. Normally, your email provider wouldn’t be allowed to give this information over without your consent or a search warrant. But that could soon change. The Senate may soon make another attempt at passing the Cybersecurity Information Sharing Act, a bill that would waive privacy laws in the name of cybersecurity. In April, the US House of Representatives passed by strong majorities two similar “cyber threat” information sharing bills. These bills grant companies immunity for giving DHS information about network attacks, attackers, and online crimes.

Sharing information about security vulnerabilities is a good idea. Shared vulnerability data empowers other system operators to check and see if they, too, have been attacked, and also to guard against being similarly attacked in the future. I’ve spent most of my career fighting for researchers’ rights to share this kind of information against threats from companies that didn’t want their customers to know their products were flawed. But, these bills gut legal protections against government fishing expeditions exactly at a time when individuals and Internet companies need privacy laws to get stronger, not weaker. 

Worse, the bills aren’t needed. Private companies share threat data with each other, and even with the government, all the time. The threat data that security professionals use to protect networks from future attacks is a far more narrow category of information than those included in the bills being considered by Congress, and will only rarely contain private information. And none of the recent cyberattacks — not Sony, not Target, and not the devastating grab of sensitive background check interviews on government employees at the Office of Personnel Management — would have been mitigated by these bills.

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.

Rather than grovel and beg for the U.S. government to respect our privacy, these innovators have taken matters into their own hands, and their work may change the playing field completely.

People used to assume that the United States government was held in check by the constitution, which prohibits unreasonable searches and seizures and which demands due process in criminal investigations, but such illusions have evaporated in recent years. It turns out that the NSA considers itself above the law in every respect and feels entitled to spy on anyone anywhere in the world without warrants, and without any real oversight. Understandably these revelations shocked the average citizen who had been conditioned to take the government's word at face value, and the backlash has been considerable. The recent "Today We Fight Back" campaign to protest the NSA's surveillance practices shows that public sentiment is in the right place. Whether these kinds of petitions and protests will have any real impact on how the U.S. government operates is questionable (to say the least), however some very smart people have decided not to wait around and find out. Instead they're focusing on making the NSA's job impossible. In the process they may fundamentally alter the way the internet operates.

Europe’s highest court on Tuesday struck down an international agreement that allowed companies to move digital information like people’s web search histories and social media updates between the European Union and the United States. The decision left the international operations of companies like Google and Facebook in a sort of legal limbo even as their services continued working as usual.The ruling, by the European Court of Justice, said the so-called safe harbor agreement was flawed because it allowed American government authorities to gain routine access to Europeans’ online information. The court said leaks from Edward J. Snowden, the former contractor for the National Security Agency, made it clear that American intelligence agencies had almost unfettered access to the data, infringing on Europeans’ rights to privacy. The court said data protection regulators in each of the European Union’s 28 countries should have oversight over how companies collect and use online information of their countries’ citizens. European countries have widely varying stances towards privacy.

Data protection advocates hailed the ruling. Industry executives and trade groups, though, said the decision left a huge amount of uncertainty for big companies, many of which rely on the easy flow of data for lucrative businesses like online advertising. They called on the European Commission to complete a new safe harbor agreement with the United States, a deal that has been negotiated for more than two years and could limit the fallout from the court’s decision.

Some European officials and many of the big technology companies, including Facebook and Microsoft, tried to play down the impact of the ruling. The companies kept their services running, saying that other agreements with the European Union should provide an adequate legal foundation.But those other agreements are now expected to be examined and questioned by some of Europe’s national privacy watchdogs. The potential inquiries could make it hard for companies to transfer Europeans’ information overseas under the current data arrangements. And the ruling appeared to leave smaller companies with fewer legal resources vulnerable to potential privacy violations.

The National Security Agency and its British counterpart, Government Communications Headquarters, have worked to subvert anti-virus and other security software in order to track users and infiltrate networks, according to documents from NSA whistleblower Edward Snowden. The spy agencies have reverse engineered software products, sometimes under questionable legal authority, and monitored web and email traffic in order to discreetly thwart anti-virus software and obtain intelligence from companies about security software and users of such software. One security software maker repeatedly singled out in the documents is Moscow-based Kaspersky Lab, which has a holding registered in the U.K., claims more than 270,000 corporate clients, and says it protects more than 400 million people with its products. British spies aimed to thwart Kaspersky software in part through a technique known as software reverse engineering, or SRE, according to a top-secret warrant renewal request. The NSA has also studied Kaspersky Lab’s software for weaknesses, obtaining sensitive customer information by monitoring communications between the software and Kaspersky servers, according to a draft top-secret report. The U.S. spy agency also appears to have examined emails inbound to security software companies flagging new viruses and vulnerabilities.

The efforts to compromise security software were of particular importance because such software is relied upon to defend against an array of digital threats and is typically more trusted by the operating system than other applications, running with elevated privileges that allow more vectors for surveillance and attack. Spy agencies seem to be engaged in a digital game of cat and mouse with anti-virus software companies; the U.S. and U.K. have aggressively probed for weaknesses in software deployed by the companies, which have themselves exposed sophisticated state-sponsored malware.

The requested warrant, provided under Section 5 of the U.K.’s 1994 Intelligence Services Act, must be renewed by a government minister every six months. The document published today is a renewal request for a warrant valid from July 7, 2008 until January 7, 2009. The request seeks authorization for GCHQ activities that “involve modifying commercially available software to enable interception, decryption and other related tasks, or ‘reverse engineering’ software.”

Warning of an erosion of confidence in the products of the U.S. technology industry, John Chambers, the CEO of networking giant Cisco Systems, has asked President Obama to intervene to curtail the surveillance activities of the National Security Agency. In a letter dated May 15 (obtained by Re/code and reprinted in full below), Chambers asked Obama to create “new standards of conduct” regarding how the NSA carries out its spying operations around the world. The letter was first reported by The Financial Times. The letter follows new revelations, including photos, published in a book based on documents leaked by former NSA contractor Edward Snowden alleging that the NSA intercepted equipment from Cisco and other manufacturers and loaded them with surveillance software. The photos, which have not been independently verified, appear to show NSA technicians working with Cisco equipment. Cisco is not said to have cooperated in the NSA’s efforts.

The debate over online anonymity, and all the whistleblowers, trolls, anarchists, journalists and political dissidents it enables, is messy enough. It doesn’t need the US government making up bogus statistics about how much that anonymity facilitates child pornography.

he debate over online anonymity, and all the whistleblowers, trolls, anarchists, journalists and political dissidents it enables, is messy enough. It doesn’t need the US government making up bogus statistics about how much that anonymity facilitates child pornography. At the State of the Net conference in Washington on Tuesday, US assistant attorney general Leslie Caldwell discussed what she described as the dangers of encryption and cryptographic anonymity tools like Tor, and how those tools can hamper law enforcement. Her statements are the latest in a growing drumbeat of federal criticism of tech companies and software projects that provide privacy and anonymity at the expense of surveillance. And as an example of the grave risks presented by that privacy, she cited a study she said claimed an overwhelming majority of Tor’s anonymous traffic relates to pedophilia. “Tor obviously was created with good intentions, but it’s a huge problem for law enforcement,” Caldwell said in comments reported by Motherboard and confirmed to me by others who attended the conference. “We understand 80 percent of traffic on the Tor network involves child pornography.” That statistic is horrifying. It’s also baloney.

In a series of tweets that followed Caldwell’s statement, a Department of Justice flack said Caldwell was citing a University of Portsmouth study WIRED covered in December. He included a link to our story. But I made clear at the time that the study claimed 80 percent of traffic to Tor hidden services related to child pornography, not 80 percent of all Tor traffic. That is a huge, and important, distinction. The vast majority of Tor’s users run the free anonymity software while visiting conventional websites, using it to route their traffic through encrypted hops around the globe to avoid censorship and surveillance. But Tor also allows websites to run Tor, something known as a Tor hidden service. This collection of hidden sites, which comprise what’s often referred to as the “dark web,” use Tor to obscure the physical location of the servers that run them. Visits to those dark web sites account for only 1.5 percent of all Tor traffic, according to the software’s creators at the non-profit Tor Project. The University of Portsmouth study dealt exclusively with visits to hidden services. In contrast to Caldwell’s 80 percent claim, the Tor Project’s director Roger Dingledine pointed out last month that the study’s pedophilia findings refer to something closer to a single percent of Tor’s overall traffic.

Director of National Intelligence James Clapper this morning released a report detailing new rules aimed at reforming the way signals intelligence is collected and stored by certain members of the United States Intelligence Community (IC). The long-awaited changes follow up on an order announced by President Obama one year ago that laid out the White House’s principles governing the collection of signals intelligence. That order, commonly known as PPD-28, purports to place limits on the use of data collected in bulk and to increase privacy protections related to the data collected, regardless of nationality. Accordingly, most of the changes presented as “new” by Clapper’s office  (ODNI) stem directly from the guidance provided in PPD-28, and so aren’t truly new. And of the biggest changes outlined in the report, there are still large exceptions that appear to allow the government to escape the restrictions with relative ease. Here’s a quick rundown.

Retention policy for non-U.S. persons. The new rules say that the IC must now delete information about “non-U.S. persons” that’s been gathered via signals intelligence after five-years. However, there is a loophole that will let spies hold onto that information indefinitely whenever the Director of National Intelligence determines (after considering the views of the ODNI’s Civil Liberties Protection Officer) that retaining information is in the interest of national security. The new rules don’t say whether the exceptions will be directed at entire groups of people or individual surveillance targets.  Section 215 metadata. Updates to the rules concerning the use of data collected under Section 215 of the Patriot Act includes the requirement that the Foreign Intelligence Surveillance Court (rather than authorized NSA officials) must determine spies have “reasonable, articulable suspicion” prior to query Section 215 data, outside of emergency circumstances. What qualifies as an emergency for these purposes? We don’t know. Additionally, the IC is now limited to two “hops” in querying the database. This means that spies can only play two degrees of Kevin Bacon, instead of the previously allowed three degrees, with the contacts of anyone targeted under Section 215. The report doesn’t explain what would prevent the NSA (or other agency using the 215 databases) from getting around this limit by redesignating a phone number found in the first or second hop as a new “target,” thereby allowing the agency to continue the contact chain.

National security letters (NSLs). The report also states that the FBI’s gag orders related to NSLs expire three years after the opening of a full-blown investigation or three years after an investigation’s close, whichever is earlier. However, these expiration dates can be easily overridden by by an FBI Special Agent in Charge or a Deputy Assistant FBI Director who finds that the statutory standards for secrecy about the NSL continue to be satisfied (which at least one court has said isn’t a very high bar). This exception also doesn’t address concerns that NSL gag orders lack adequate due process protections, lack basic judicial oversight, and may violate the First Amendment.

European officials are demanding answers and investigations into a joint U.S. and U.K. hack of the world’s largest manufacturer of mobile SIM cards, following a report published by The Intercept Thursday. The report, based on leaked documents provided by NSA whistleblower Edward Snowden, revealed the U.S. spy agency and its British counterpart Government Communications Headquarters, GCHQ, hacked the Franco-Dutch digital security giant Gemalto in a sophisticated heist of encrypted cell-phone keys. The European Parliament’s chief negotiator on the European Union’s data protection law, Jan Philipp Albrecht, said the hack was “obviously based on some illegal activities.” “Member states like the U.K. are frankly not respecting the [law of the] Netherlands and partner states,” Albrecht told the Wall Street Journal. Sophie in ’t Veld, an EU parliamentarian with D66, the Netherlands’ largest opposition party, added, “Year after year we have heard about cowboy practices of secret services, but governments did nothing and kept quiet […] In fact, those very same governments push for ever-more surveillance capabilities, while it remains unclear how effective these practices are.”

“If the average IT whizzkid breaks into a company system, he’ll end up behind bars,” In ’t Veld added in a tweet Friday. The EU itself is barred from undertaking such investigations, leaving individual countries responsible for looking into cases that impact their national security matters. “We even get letters from the U.K. government saying we shouldn’t deal with these issues because it’s their own issue of national security,” Albrecht said. Still, lawmakers in the Netherlands are seeking investigations. Gerard Schouw, a Dutch member of parliament, also with the D66 party, has called on Ronald Plasterk, the Dutch minister of the interior, to answer questions before parliament. On Tuesday, the Dutch parliament will debate Schouw’s request. Additionally, European legal experts tell The Intercept, public prosecutors in EU member states that are both party to the Cybercrime Convention, which prohibits computer hacking, and home to Gemalto subsidiaries could pursue investigations into the breach of the company’s systems.

According to secret documents from 2010 and 2011, a joint NSA-GCHQ unit penetrated Gemalto’s internal networks and infiltrated the private communications of its employees in order to steal encryption keys, embedded on tiny SIM cards, which are used to protect the privacy of cellphone communications across the world. Gemalto produces some 2 billion SIM cards a year. The company’s clients include AT&T, T-Mobile, Verizon, Sprint and some 450 wireless network providers. “[We] believe we have their entire network,” GCHQ boasted in a leaked slide, referring to the Gemalto heist.

Despite the post-Snowden spotlight on mass surveillance, the intelligence community’s easiest end-run around the Fourth Amendment since 2001 has been something called a National Security Letter. FBI agents can demand that an Internet service provider, telephone company or financial institution turn over its records on any number of people — without any judicial review whatsoever — simply by writing a letter that says the information is needed for national security purposes. The FBI at one point was cranking out over 50,000 such letters a year; by the latest count, it still issues about 60 a day. The letters look like this:

Recipients are legally required to comply — but it doesn’t stop there. They also aren’t allowed to mention the order to anyone, least of all the person whose data is being searched. Ever. That’s because National Security Letters almost always come with eternal gag orders. Here’s that part:

Despite the use of the word “now” in that first sentence, however, the FBI has yet to do any such thing. It has not announced any such change, nor explained how it will implement it, or when. Media inquiries were greeted with stalling and, finally, a no comment — ostensibly on advice of legal counsel. “There is pending litigation that deals with a lot of the same questions you’re asking, out of the Ninth Circuit,” FBI spokesman Chris Allen told me. “So for now, we’ll just have to decline to comment.” FBI lawyers are working on a court filing for that case, and “it will address” the new policy, he said. He would not say when to expect it.

China’s new draft anti-terror legislation has sent waves across the U.S. tech community. If there is a brewing tech war between U.S. and China over government surveillance backdoors and a preference for indigenous software, China’s new draft terror law makes it clear that Beijing is happy to give the United States a taste of its own medicine. The law has already drawn considerable criticism from international human rights groups, including Amnesty International and Human Rights Watch for its purported attempts to legitimize wanton human rights violations in the name of counter-terrorism. Additionally, China has opted to implement its own definition of terrorism, placing  “any thought, speech, or activity that, by means of violence, sabotage, or threat, aims to generate social panic, influence national policy-making, create ethnic hatred, subvert state power, or split the state” under the umbrella of the overused T-word. The problematic human rights issues aside, the draft anti-terror law will have important implications for foreign tech firms within China. According to Reuters’ reporting on the draft anti-terror law, counter-terrorism precautions by the Chinese government would essentially require foreign firms to “hand over encryption keys and install security ‘backdoors’” into their software. Additionally, these firms would have to store critical data — certainly data on Chinese citizens and residents — on Chinese soil. The onerous implications of this law could have lead to an immediate freeze to the activities of several Western tech companies in China, the world’s second largest economy and a booming emerging market for new technologies.

On the surface, the most troublesome implication of this law is that in order to comply with this law, Western firms, including non-technical ventures such as financial institutions and manufacturers, will be forced to give up a great deal of security. In essence, corporate secrets, financial data — all critical data — would be insecure and available for access by Chinese regulators. The new law would also prohibit the use of secure virtual private networks (VPNs) to get around these requirements.

The U.S. diplomatic response to Beijing’s new draft law is perhaps best captured in the fact that a whopping four cabinet members in the Obama administration, including Secretary of State John Kerry and U.S. Trade Representative Michael Froman, wrote the Chinese government expressing “serious concern.” China, for its part, seemed unfazed by U.S. concerns. Foreign Ministry spokesperson Hua Chunying told the press that she hoped the United States would view the new anti-terror precautions in “in a calm and objective way.” Indeed, following Edward Snowden’s revelations regarding the extent of the United States’ surveillance of private firms both within and outside the United States, Beijing likely views U.S. concerns as hypocritical. One U.S. industry source told Reuters that the new law was ”the equivalent of the Patriot Act on really, really strong steroids.”

An internal CIA investigation confirmed allegations that agency personnel improperly intruded into a protected database used by Senate Intelligence Committee staff to compile a scathing report on the agency’s detention and interrogation program, prompting bipartisan outrage and at least two calls for spy chief John Brennan to resign.“This is very, very serious, and I will tell you, as a member of the committee, someone who has great respect for the CIA, I am extremely disappointed in the actions of the agents of the CIA who carried out this breach of the committee’s computers,” said Sen. Saxby Chambliss, R-Ga., the committee’s vice chairman.

The rare display of bipartisan fury followed a three-hour private briefing by Inspector General David Buckley. His investigation revealed that five CIA employees, two lawyers and three information technology specialists improperly accessed or “caused access” to a database that only committee staff were permitted to use.Buckley’s inquiry also determined that a CIA crimes report to the Justice Department alleging that the panel staff removed classified documents from a top-secret facility without authorization was based on “inaccurate information,” according to a summary of the findings prepared for the Senate and House intelligence committees and released by the CIA.In other conclusions, Buckley found that CIA security officers conducted keyword searches of the emails of staffers of the committee’s Democratic majority _ and reviewed some of them _ and that the three CIA information technology specialists showed “a lack of candor” in interviews with Buckley’s office.

The inspector general’s summary did not say who may have ordered the intrusion or when senior CIA officials learned of it.Following the briefing, some senators struggled to maintain their composure over what they saw as a violation of the constitutional separation of powers between an executive branch agency and its congressional overseers.“We’re the only people watching these organizations, and if we can’t rely on the information that we’re given as being accurate, then it makes a mockery of the entire oversight function,” said Sen. Angus King, an independent from Maine who caucuses with the Democrats.The findings confirmed charges by the committee chairwoman, Sen. Dianne Feinstein, D-Calif., that the CIA intruded into the database that by agreement was to be used by her staffers compiling the report on the harsh interrogation methods used by the agency on suspected terrorists held in secret overseas prisons under the George W. Bush administration.The findings also contradicted Brennan’s denials of Feinstein’s allegations, prompting two panel members, Sens. Mark Udall, D-Colo., and Martin Heinrich, D-N.M., to demand that the spy chief resign.

Complex malware known as Regin is the suspected technology behind sophisticated cyberattacks conducted by U.S. and British intelligence agencies on the European Union and a Belgian telecommunications company, according to security industry sources and technical analysis conducted by The Intercept. Regin was found on infected internal computer systems and email servers at Belgacom, a partly state-owned Belgian phone and internet provider, following reports last year that the company was targeted in a top-secret surveillance operation carried out by British spy agency Government Communications Headquarters, industry sources told The Intercept. The malware, which steals data from infected systems and disguises itself as legitimate Microsoft software, has also been identified on the same European Union computer systems that were targeted for surveillance by the National Security Agency.

The hacking operations against Belgacom and the European Union were first revealed last year through documents leaked by NSA whistleblower Edward Snowden. The specific malware used in the attacks has never been disclosed, however.
