Last week, the Administrative Office (AO) of the US Courts published the 2014 Wiretap Report, an annual report to Congress concerning intercepted wire, oral, or electronic communications as required by Title III of the Omnibus Crime Control and Safe Streets Act of 1968. News headlines touted that the number of federal and state wiretaps for 2014 was down 1% for a total of 3,554. Of these, there were few involving encrypted communications; and for those, law enforcement agencies were in most cases able to overcome the encryption. But there is a bigger story that calls into question the accuracy of the all of the prior reports submitted to the AO and the overall data provided to Congress and the public in the Wiretap Reports. Since the Snowden revelations, more and more companies have started publishing “transparency reports” about the number and nature of government demands to access their users’ data. AT&T, Verizon, and Sprint published data for 2014 earlier this year and T-Mobile published its first transparency report on the same day the AO released the Wiretap Report. In aggregate, the four companies state that they implemented 10,712 wiretaps, a threefold difference over the total number reported by the AO. Note that the 10,712 number is only for the four companies listed above and does not reflect wiretap orders received by other telephone carriers or online providers, so the discrepancy actually is larger.

So what accounts for the huge gap in reporting? That is a question Congress and the AO should be asking prosecutors and judges who are required by law to make complete and accurate reports of the number of wiretaps conducted each year. Are wiretaps being consistently under­reported to Congress and the public? Based on the data reported by the four major carriers for 2013 and 2014, it certainly would appear to be the case.

It’s true that ordering Apple to develop the backdoor will fundamentally undermine iPhone security, as Cook and other digital security advocates have argued. But it’s possible for individual iPhone users to protect themselves from government snooping by setting strong passcodes on their phones — passcodes the FBI would not be able to unlock even if it gets its iPhone backdoor. The technical details of how the iPhone encrypts data, and how the FBI might circumvent this protection, are complex and convoluted, and are being thoroughly explored elsewhere on the internet. What I’m going to focus on here is how ordinary iPhone users can protect themselves. The short version: If you’re worried about governments trying to access your phone, set your iPhone up with a random, 11-digit numeric passcode. What follows is an explanation of why that will protect you and how to actually do it.

If the U.S. Department of Justice asks a New York court to force Apple Inc to unlock an iPhone, the technology company could push the government to reveal how it accessed the phone which belonged to a shooter in San Bernardino, a source familiar with the situation said.The Justice Department will disclose over the next two weeks whether it will continue with its bid to compel Apple to help access an iPhone in a Brooklyn drug case, according to a court filing on Tuesday.The Justice Department this week withdrew a similar request in California, saying it had succeeded in unlocking an iPhone used by one of the shooters involved in a rampage in San Bernardino in December without Apple's help.The legal dispute between the U.S. government and Apple has been a high-profile test of whether law enforcement should have access to encrypted phone data.

Apple, supported by most of the technology industry, says anything that helps authorities bypass security features will undermine security for all users. Government officials say that all kinds of criminal investigations will be crippled without access to phone data.Prosecutors have not said whether the San Bernardino technique would work for other seized iPhones, including the one at issue in Brooklyn. Should the Brooklyn case continue, Apple could pursue legal discovery that would potentially force the FBI to reveal what technique it used on the San Bernardino phone, the source said. A Justice Department representative did not have immediate comment.

Apparent National Security Agency (NSA) malware has been used in a global cyber-attack, including on British hospitals, in what whistleblower Edward Snowden described as the repercussion of the NSA’s reckless decision to build the tools. “Despite warnings, @NSAGov built dangerous attack tools that could target Western software. Today we see the cost,” Snowden tweeted Friday. At least two hospitals in London were forced to shut down and stop admitting patients after being attacked by the malware, which operates by locking out the user, encrypting data, and demanding a ransom to release it. The attacks hit dozens of other hospitals, ambulance operators, and doctors’ offices as well.

The Blackpool Gazette in the northwest reported that medical staff had resorted to using pen and paper when phone and computer systems shut down. Elsewhere, journalist Ollie Cowan tweeted a photo of ambulances “backed up” at Southport Hospital as the staff attempted to cope with the crisis.

Other disruptions were reported in at least 74 countries, including Russia, Spain, Turkey, and Japan, and the number is “growing fast,” according to Kaspersky Lab chief Costin Raiu. Security architect Kevin Beau said it was spreading into the U.S. as well. The malware, which Microsoft tested briefly earlier this year, was leaked by a group calling itself the Shadow Brokers, which has been releasing NSA hacking tools online since last year, the New York Times reports. Times journalists Dan Bilefsky and Nicole Perlroth wrote: Microsoft rolled out a patch for the vulnerability in March, but hackers apparently took advantage of the fact that vulnerable targets—particularly hospitals—had yet to update their systems. The malware was circulated by email. Targets were sent an encrypted, compressed file that, once loaded, allowed the ransomware to infiltrate its targets. Reuters reported that the National Health Service (NHS), England’s public health system, was warned about possible hacking earlier in the day, but that by then it was already too late.

The American Civil Liberties Union (ACLU) has filed a motion to reveal the secret court opinions with “novel or significant interpretations” of surveillance law, in a renewed push for government transparency. The motion, filed Wednesday by the ACLU and Yale Law School’s Media Freedom and Information Access Clinic, asks the Foreign Intelligence Surveillance Act (FISA) Court, which rules on intelligence gathering activities in secret, to release 23 classified decisions it made between 9/11 and the passage of the USA Freedom Act in June 2015. As ACLU National Security Project staff attorney Patrick Toomey explains, the opinions are part of a “much larger collection of hidden rulings on all sorts of government surveillance activities that affect the privacy rights of Americans.” Among them is the court order that the government used to direct Yahoo to secretly scanits users’ emails for “a specific set of characters.” Toomey writes: These court rulings are essential for the public to understand how federal laws are being construed and implemented. They also show how constitutional protections for personal privacy and expressive activities are being enforced by the courts. In other words, access to these opinions is necessary for the public to properly oversee their government.

Although the USA Freedom Act requires the release of novel FISA court opinions on surveillance law, the government maintains that the rule does not apply retroactively—thereby protecting the panel from publishing many of its post-9/11 opinions, which helped create an “unprecedented buildup” of secret surveillance laws. Even after National Security Agency (NSA) whistleblower Edward Snowden revealed the scope of mass surveillance in 2013, sparking widespread outcry, dozens of rulings on spying operations remain hidden from the public eye, which stymies efforts to keep the government accountable, civil liberties advocates say. “These rulings are necessary to inform the public about the scope of the government’s surveillance powers today,” the ACLU’s motion states.

Toomey writes that the rulings helped influence a number of novel spying activities, including: The government’s use of malware, which it calls “Network Investigative Techniques” The government’s efforts to compel technology companies to weaken or circumvent their own encryption protocols The government’s efforts to compel technology companies to disclose their source code so that it can identify vulnerabilities The government’s use of “cybersignatures” to search through internet communications for evidence of computer intrusions The government’s use of stingray cell-phone tracking devices under the Foreign Intelligence Surveillance Act (FISA) The government’s warrantless surveillance of Americans under FISA Section 702—a controversial authority scheduled to expire in December 2017 The bulk collection of financial records by the CIA and FBI under Section 215 of the Patriot Act Without these rulings being made public, “it simply isn’t possible to understand the government’s claimed authority to conduct surveillance,” Toomey writes. As he told The Intercept on Wednesday, “The people of this country can’t hold the government accountable for its surveillance activities unless they know what our laws allow. These secret court opinions define the limits of the government’s spying powers. Their disclosure is essential for meaningful public oversight in our democracy.”

In our society, the rule of law sets limits on what government can and cannot do, no matter how important its goals. To give a simple example, even when chasing a fleeing murder suspect, the police have a duty not to endanger bystanders. The government should pay the same care to our safety in pursuing threats online, but right now we don’t have clear, enforceable rules for government activities like hacking and "digital sabotage." And this is no abstract question—these actions increasingly endanger everyone’s security

The problem became especially clear this year during the San Bernardino case, involving the FBI’s demand that Apple rewrite its iOS operating system to defeat security features on a locked iPhone. Ultimately the FBI exploited an existing vulnerability in iOS and accessed the contents of the phone with the help of an "outside party." Then, with no public process or discussion of the tradeoffs involved, the government refused to tell Apple about the flaw. Despite the obvious fact that the security of the computers and networks we all use is both collective and interwoven—other iPhones used by millions of innocent people presumably have the same vulnerability—the government chose to withhold information Apple could have used to improve the security of its phones. Other examples include intelligence activities like Stuxnet and Bullrun, and law enforcement investigations like the FBI’s mass use of malware against Tor users engaged in criminal behavior. These activities are often disproportionate to stopping legitimate threats, resulting in unpatched software for millions of innocent users, overbroad surveillance, and other collateral effects.  That’s why we’re working on a positive agenda to confront governmental threats to digital security. Put more directly, we’re calling on lawyers, advocates, technologists, and the public to demand a public discussion of whether, when, and how governments can be empowered to break into our computers, phones, and other devices; sabotage and subvert basic security protocols; and stockpile and exploit software flaws and vulnerabilities.  

Smart people in academia and elsewhere have been thinking and writing about these issues for years. But it’s time to take the next step and make clear, public rules that carry the force of law to ensure that the government weighs the tradeoffs and reaches the right decisions. This long post outlines some of the things that can be done. It frames the issue, then describes some of the key areas where EFF is already pursuing this agenda—in particular formalizing the rules for disclosing vulnerabilities and setting out narrow limits for the use of government malware. Finally it lays out where we think the debate should go from here.   

“A program obfuscator would be a powerful tool for finding plausible constructions for just about any cryptographic task you could conceive of,” said Yuval Ishai, of the Technion in Haifa, Israel. Precisely because of obfuscation’s power, many computer scientists, including Sahai and his colleagues, thought it was impossible. “We were convinced it was too powerful to exist,” he said. Their earliest research findings seemed to confirm this, showing that the most natural form of obfuscation is indeed impossible to achieve for all programs. Then, on July 20, 2013, Sahai and five co-authors posted a paper on the Cryptology ePrint Archive demonstrating a candidate protocol for a kind of obfuscation known as “indistinguishability obfuscation.” Two days later, Sahai and one of his co-authors, Brent Waters, of the University of Texas, Austin, posted a second paper that suggested, together with the first paper, that this somewhat arcane form of obfuscation may possess much of the power cryptographers have dreamed of. “This is the first serious positive result” when it comes to trying to find a universal obfuscator, said Boaz Barak, of Microsoft Research in Cambridge, Mass. “The cryptography community is very excited.” In the six months since the original paper was posted, more papers have appeared on the ePrint archive with “obfuscation” in the title than in the previous 17 years.

Theresa May summoned the internet giant Yahoo for an urgent meeting on Thursday to raise security concerns after the company announced plans to move to Dublin where it is beyond the reach of Britain's surveillance laws.By making the Irish capital rather than London the centre of its European, Middle East and Africa operations, Yahoo cannot be forced to hand over information demanded by Scotland Yard and the intelligence agencies through "warrants" issued under Britain's controversial anti-terror laws.Yahoo has had longstanding concerns about securing the privacy of its hundreds of millions of users – anxieties that have been heightened in recent months by revelations from the whistleblower Edward Snowden.

In February, the Guardian revealed that Britain's eavesdropping centre GCHQ intercepted and stored the images of millions of people using Yahoo webcams, regardless of whether they were suspects. The data included a large quantity of sexually explicit pictures.The company said this represented "a whole new level of violation of our users' privacy".The home secretary called the meeting with Yahoo to express the fears of Britain's counter-terrorism investigators. They can force companies based in the UK to provide information on their servers by seeking warrants under the Regulation of Investigatory Powers Act, 2000 (Ripa).

the Guardian has been told that Charles Farr, the head of the office for security and counter-terrorism (OSCT) within the Home Office, has been pressing May to talk to Yahoo because of anxiety in Scotland Yard's counter-terrorism command about the effect the move to Dublin could have on their inquiries.Farr, a former senior intelligence officer, coordinates the work of Scotland Yard and the security service MI5, to prevent terrorist attacks in the UK."There are concerns in the Home Office about how Ripa will apply to Yahoo once it has moved its headquarters to Dublin," said a Whitehall source. "The home secretary asked to see officials from Yahoo because in Dublin they don't have equivalent laws to Ripa. This could particularly affect investigations led by Scotland Yard and the national crime agency. They regard this as a very serious issue."

All existing data sharing agreements between Europe and the US should be revoked, and US web site providers should prominently inform European citizens that their data may be subject to government surveillance, according to the recommendations of a briefing report for the European Parliament. The report was produced in response to revelations about the US National Security Agency (NSA) snooping on internet traffic, and aims to highlight the subsequent effect on European Union (EU) citizens' rights.

The report warns that EU data protection authorities have failed to understand the “structural shift of data sovereignty implied by cloud computing”, and the associated risks to the rights of EU citizens. It suggests “a full industrial policy for development of an autonomous European cloud computing capacity” should be set up to reduce exposure of EU data to NSA surveillance that is undertaken by the use of US legislation that forces US-based cloud providers to provide access to data they hold.

To put pressure on the US government, the report recommends that US websites should ask EU citizens for their consent before gathering data that could be used by the NSA. “Prominent notices should be displayed by every US web site offering services in the EU to inform consent to collect data from EU citizens. The users should be made aware that the data may be subject to surveillance by the US government for any purpose which furthers US foreign policy,” it said. “A consent requirement will raise EU citizen awareness and favour growth of services solely within EU jurisdiction. This will thus have economic impact on US business and increase pressure on the US government to reach a settlement.”
