Cy Vance's Proposal to Backdoor Encrypted Devices Is Riddled With Vulnerabilities | Jus... - 0 views

  • 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.

  • Vance attempts to downplay this serious risk by asserting that anyone can use the “Find My Phone” or Android Device Manager services that allow owners to delete the data on their phones if stolen. However, this does not stand up to scrutiny. These services are effective only when an owner realizes their phone is missing and can take swift action on another computer or device. This delay ensures some period of vulnerability. Encryption, on the other hand, protects everyone immediately and always. Additionally, Vance argues that it is safer to build backdoors into encrypted devices than it is to do so for encrypted communications in transit. It is true that there is a difference in the threats posed by the two types of encryption backdoors that are being debated. However, some manner of widespread vulnerability will inevitably result from a backdoor to encrypted devices. Indeed, the NSA and GCHQ reportedly hacked into a database to obtain cell phone SIM card encryption keys in order defeat the security protecting users’ communications and activities and to conduct surveillance. Clearly, the reality is that the threat of such a breach, whether from a hacker or a nation state actor, is very real. Even if companies go the extra mile and create a different means of access for every phone, such as a separate access key for each phone, significant vulnerabilities will be created. It would still be possible for a malicious actor to gain access to the database containing those keys, which would enable them to defeat the encryption on any smartphone they took possession of. Additionally, the cost of implementation and maintenance of such a complex system could be high.
  • Privacy is another concern that Vance dismisses too easily. Despite Vance’s arguments otherwise, building backdoors into device encryption undermines privacy. Our government does not impose a similar requirement in any other context. Police can enter homes with warrants, but there is no requirement that people record their conversations and interactions just in case they someday become useful in an investigation. The conversations that we once had through disposable letters and in-person conversations now happen over the Internet and on phones. Just because the medium has changed does not mean our right to privacy has.
  • In addition to his weak reasoning for why it would be feasible to create backdoors to encrypted devices without creating undue security risks or harming privacy, Vance makes several flawed policy-based arguments in favor of his proposal. He argues that criminals benefit from devices that are protected by strong encryption. That may be true, but strong encryption is also a critical tool used by billions of average people around the world every day to protect their transactions, communications, and private information. Lawyers, doctors, and journalists rely on encryption to protect their clients, patients, and sources. Government officials, from the President to the directors of the NSA and FBI, and members of Congress, depend on strong encryption for cybersecurity and data security. There are far more innocent Americans who benefit from strong encryption than there are criminals who exploit it. Encryption is also essential to our economy. Device manufacturers could suffer major economic losses if they are prohibited from competing with foreign manufacturers who offer more secure devices. Encryption also protects major companies from corporate and nation-state espionage. As more daily business activities are done on smartphones and other devices, they may now hold highly proprietary or sensitive information. Those devices could be targeted even more than they are now if all that has to be done to access that information is to steal an employee’s smartphone and exploit a vulnerability the manufacturer was required to create.
  • Vance also suggests that the US would be justified in creating such a requirement since other Western nations are contemplating requiring encryption backdoors as well. Regardless of whether other countries are debating similar proposals, we cannot afford a race to the bottom on cybersecurity. Heads of the intelligence community regularly warn that cybersecurity is the top threat to our national security. Strong encryption is our best defense against cyber threats, and following in the footsteps of other countries by weakening that critical tool would do incalculable harm. Furthermore, even if the US or other countries did implement such a proposal, criminals could gain access to devices with strong encryption through the black market. Thus, only innocent people would be negatively affected, and some of those innocent people might even become criminals simply by trying to protect their privacy by securing their data and devices. Finally, Vance argues that David Kaye, UN Special Rapporteur for Freedom of Expression and Opinion, supported the idea that court-ordered decryption doesn’t violate human rights, provided certain criteria are met, in his report on the topic. However, in the context of Vance’s proposal, this seems to conflate the concepts of court-ordered decryption and of government-mandated encryption backdoors. The Kaye report was unequivocal about the importance of encryption for free speech and human rights. The report concluded that:
  • States should promote strong encryption and anonymity. National laws should recognize that individuals are free to protect the privacy of their digital communications by using encryption technology and tools that allow anonymity online. … States should not restrict encryption and anonymity, which facilitate and often enable the rights to freedom of opinion and expression. Blanket prohibitions fail to be necessary and proportionate. States should avoid all measures that weaken the security that individuals may enjoy online, such as backdoors, weak encryption standards and key escrows. Additionally, the group of intelligence experts that was hand-picked by the President to issue a report and recommendations on surveillance and technology, concluded that: [R]egarding encryption, the U.S. Government should: (1) fully support and not undermine efforts to create encryption standards; (2) not in any way subvert, undermine, weaken, or make vulnerable generally available commercial software; and (3) increase the use of encryption and urge US companies to do so, in order to better protect data in transit, at rest, in the cloud, and in other storage.
  • The clear consensus among human rights experts and several high-ranking intelligence experts, including the former directors of the NSA, Office of the Director of National Intelligence, and DHS, is that mandating encryption backdoors is dangerous. Unaddressed Concerns: Preventing Encrypted Devices from Entering the US and the Slippery Slope In addition to the significant faults in Vance’s arguments in favor of his proposal, he fails to address the question of how such a restriction would be effectively implemented. There is no effective mechanism for preventing code from becoming available for download online, even if it is illegal. One critical issue the Vance proposal fails to address is how the government would prevent, or even identify, encrypted smartphones when individuals bring them into the United States. DHS would have to train customs agents to search the contents of every person’s phone in order to identify whether it is encrypted, and then confiscate the phones that are. Legal and policy considerations aside, this kind of policy is, at the very least, impractical. Preventing strong encryption from entering the US is not like preventing guns or drugs from entering the country — encrypted phones aren’t immediately obvious as is contraband. Millions of people use encrypted devices, and tens of millions more devices are shipped to and sold in the US each year.
  • Finally, there is a real concern that if Vance’s proposal were accepted, it would be the first step down a slippery slope. Right now, his proposal only calls for access to smartphones and devices running mobile operating systems. While this policy in and of itself would cover a number of commonplace devices, it may eventually be expanded to cover laptop and desktop computers, as well as communications in transit. The expansion of this kind of policy is even more worrisome when taking into account the speed at which technology evolves and becomes widely adopted. Ten years ago, the iPhone did not even exist. Who is to say what technology will be commonplace in 10 or 20 years that is not even around today. There is a very real question about how far law enforcement will go to gain access to information. Things that once seemed like merely science fiction, such as wearable technology and artificial intelligence that could be implanted in and work with the human nervous system, are now available. If and when there comes a time when our “smart phone” is not really a device at all, but is rather an implant, surely we would not grant law enforcement access to our minds.
  • Policymakers should dismiss Vance’s proposal to prohibit the use of strong encryption to protect our smartphones and devices in order to ensure law enforcement access. Undermining encryption, regardless of whether it is protecting data in transit or at rest, would take us down a dangerous and harmful path. Instead, law enforcement and the intelligence community should be working to alter their skills and tactics in a fast-evolving technological world so that they are not so dependent on information that will increasingly be protected by encryption.

Challenge to data transfer tool used by Facebook will go to Europe's top court | TechCr... - 1 views

  • The five-week court hearing in what is a complex case delving into detail on US surveillance operations took place in February. The court issued its ruling today. The 153-page ruling starts by noting “this is an unusual case”, before going into a detailed discussion of the arguments and concluding that the DPC’s concerns about the validity of SCCs should be referred to the European Court of Justice for a preliminary ruling. Schrems is also the man responsible for bringing, in 2013, a legal challenge that ultimately struck down Safe Harbor — the legal mechanism that had oiled the pipe for EU-US personal data flows for fifteen years before the ECJ ruled it to be invalid in October 2015. Schrems’ argument had centered on U.S. government mass surveillance programs, as disclosed via the Snowden leaks, being incompatible with fundamental European privacy rights. After the ECJ struck down Safe Harbor he then sought to apply the same arguments against Facebook’s use of SCCs — returning to Ireland to make the complaint as that’s where the company has its European HQ. It’s worth noting that the European Commission has since replaced Safe Harbor with a new (and it claims more robust) data transfer mechanism, called the EU-US Privacy Shield — which is now, as Safe Harbor was, used by thousands of businesses. Although that too is facing legal challenges as critics continue to argue there is a core problem of incompatibility between two distinct legal regimes where EU privacy rights collide with US mass surveillance.
  • In a written statement on the ruling Schrems added: “I welcome the judgement by the Irish High Court. It is important that a neutral Court outside of the US has summarized the facts on US surveillance in a judgement, after diving through more than 45,000 pages of documents in a five week hearing.
  • Making a video statement outside court in Dublin today, Schrems said the Irish court had dismissed Facebook’s argument that the US government does not undertake any surveillance.

  • Schrems’ Safe Harbor challenge also started in the Irish Court before being ultimately referred to the ECJ. So there’s more than a little legal deja vu here, especially given the latest development in the case. In its ruling on the SCC issue, the Irish Court noted that a US ombudsperson position created under Privacy Shield to handle EU citizens complaints about companies’ handling of their data is not enough to overcome what it described as “well founded concerns” raised by the DPC regarding the adequacy of the protections for EU citizens data.
  • On Facebook, he also said: “In simple terms, US law requires Facebook to help the NSA with mass surveillance and EU law prohibits just that. As Facebook is subject to both jurisdictions, they got themselves in a legal dilemma that they cannot possibly solve in the long run.”
  • While Schrems’ original complaint pertained to Facebook, the Irish DPC’s position means many more companies that use the mechanism could face disruption if SCCs are ultimately invalidated as a result of the legal challenge to their validity.

YouTube To Censor "Controversial" Content, ADL On Board As Flagger - 0 views

  • Chief among the groups seeking to clamp down on independent media has been Google, the massive technology company with deep connections to the U.S. intelligence community, as well as to U.S. government and business elites.
  • Since 2015, Google has worked to become the Internet’s “Ministry of Truth,” first through its creation of the First Draft Coalition and more recently via major changes made to its search engine that curtail public access to new sites independent of the corporate media.
  • Google has now stepped up its war on free speech and the freedom of the press through its popular subsidiary, YouTube. On Tuesday, YouTube announced online that it is set to begin censoring content deemed “controversial,” even if that content does not break any laws or violate YouTube’s user agreement. Misleadingly dubbed as an effort “to fight terror content online,” the new program will flag content for review through a mix of machine algorithms and “human review,” guided by standards set up by “expert NGOs and institutions” that are part of YouTube’s “Trusted Flagger” program. YouTube stated that such organizations “bring expert knowledge of complex issues like hate speech, radicalization, and terrorism.” One of the leading institutions directing the course of the Trusted Flagger program is the Anti-Defamation League (ADL). The ADL was initially founded to “stop the defamation of the Jewish people and to secure justice and fair treatment to all” but has gained a reputation over the years for labeling any critic of Israel’s government as an “anti-Semite.” For instance, characterizing Israeli policies towards the Palestinians as “racist” or “apartheid-like” is considered “hate speech” by the ADL, as is accusing Israel of war crimes or attempted ethnic cleansing. The ADL has even described explicitly Jewish organizations who are critical of Israel’s government as being “anti-Semitic.”

FCC Turns Itself into a Deregulatory Agency - WhoWhatWhy - 2 views

  • Since taking office, President Donald Trump has wasted no time in proposing rollbacks to Obama-era federal regulations. So, it should come as no surprise that the Federal Communications Commission (FCC) voted last month to propose changes to current regulations on Internet service providers. Spearheaded by Ajit Pai — the Trump-appointed FCC chairman and former lawyer for Verizon — the 2-1 vote is the first step in dismantling the Open Internet Order. The lone FCC Democrat, Mignon Clyburn, was overruled by Pai and fellow commissioner Michael O’Reilly. The 2015 order classified broadband internet as a utility under Title II of the Communications Act of 1934. Opponents of the current state of net neutrality argue that the rules are archaic and place unnecessary — even harmful — restrictions on internet service providers (ISPs), leading to lack of innovation and investment. While it’s true that policies conceived in the 1930s could hardly anticipate the complexities of the modern Internet, a complete rollback of Title II protections would leave ISPs free to favor their own services and whichever company pays for upgraded service. Considering relaxed FEC rules on media ownership and lack of antitrust enforcement, some could argue that a rollback of net neutrality is even more toxic to innovation and affordable pricing. That is, fast lanes could be created for companies with deeper pockets, effectively giving them an advantage over companies and individuals who can’t pay extra. This approach effectively penalizes small businesses, nonprofits and innovative start-ups. Today’s Internet is so vast and so pervasive that it’s hard to grasp the impact that an abandonment of net neutrality would have on every aspect of our culture.
  • While the FCC’s proposed change will touch most Americans, net neutrality remains a mystifying concept to non-techies. To help our readers better understand the issue, we have compiled some videos that explain net neutrality and its importance. The FCC will be accepting comments from the public on their website until August 16, 2017.

Superiority in Cyberspace Will Remain Elusive - Federation Of American Scientists - 0 views

  • Military planners should not anticipate that the United States will ever dominate cyberspace, the Joint Chiefs of Staff said in a new doctrinal publication. The kind of supremacy that might be achievable in other domains is not a realistic option in cyber operations. “Permanent global cyberspace superiority is not possible due to the complexity of cyberspace,” the DoD publication said. In fact, “Even local superiority may be impractical due to the way IT [information technology] is implemented; the fact US and other national governments do not directly control large, privately owned portions of cyberspace; the broad array of state and non-state actors; the low cost of entry; and the rapid and unpredictable proliferation of technology.” Nevertheless, the military has to make do under all circumstances. “Commanders should be prepared to conduct operations under degraded conditions in cyberspace.” This sober assessment appeared in a new edition of Joint Publication 3-12, Cyberspace Operations, dated June 8, 2018. (The 100-page document updates and replaces a 70-page version from 2013.) The updated DoD doctrine presents a cyber concept of operations, describes the organization of cyber forces, outlines areas of responsibility, and defines limits on military action in cyberspace, including legal limits.
  • The new cyber doctrine reiterates the importance and the difficulty of properly attributing cyber attacks against the US to their source. “The ability to hide the sponsor and/or the threat behind a particular malicious effect in cyberspace makes it difficult to determine how, when, and where to respond,” the document said. “The design of the Internet lends itself to anonymity and, combined with applications intended to hide the identity of users, attribution will continue to be a challenge for the foreseeable future.”
