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.

Invisible, targeted infrared light can fool facial recognition software into thinking a... - 0 views

  • A group of Chinese computer scientists from academia and industry have published a paper documenting a tool for fooling facial recognition software by shining hat-brim-mounted infrared LEDs on the user's face, projecting CCTV-visible, human-eye-invisible shapes designed to fool the face recognition software. The tactic lets the attacker specify which face the categorizer should "see" -- the researchers were able to trick the software into recognizing arbitrary faces as belonging to the musician Moby, the Korean politician Hoi-Chang and others.

NSA Based Malware Used In Massive Cyber-Attack Hitting 74 Countries - 0 views

  • 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.

  • A Twitter account with the handle @HackerFantastic, the co-founder of the cyber security company Hacker House, tweeted that the firm had “warned the NHS with Sky news about vulnerabilities they had last year, this was inevitable and bound to happen at some stage.” “In light of today’s attack, Congress needs to be asking @NSAgov if it knows of any other vulnerabilities in software used in our hospitals,” Snowden tweeted. “If @NSAGov had privately disclosed the flaw used to attack hospitals when they *found* it, not when they lost it, this may not have happened.” Disclosing the vulnerability when it was found would have given hospitals years, not months, to update their systems and prepare for an attack, he added.
  • witter user @MalwareTechBlog added, “Something like this is incredibly significant, we’ve not seen P2P spreading on PC via exploits at this scale in nearly a decade.” Patrick Toomey, a staff attorney with the American Civil Liberties Union’s (ACLU) National Security Project, said, “It would be shocking if the NSA knew about this vulnerability but failed to disclose it to Microsoft until after it was stolen.” “These attacks underscore the fact that vulnerabilities will be exploited not just by our security agencies, but by hackers and criminals around the world,” Toomey said. “It is past time for Congress to enhance cybersecurity by passing a law that requires the government to disclose vulnerabilities to companies in a timely manner. Patching security holes immediately, not stockpiling them, is the best way to make everyone’s digital life safer.”

Trump Declares War On Silicon Valley: DoJ Launches Google Anti-Monopoly Probe | Zero Hedge - 0 views

  • Just before midnight on Friday, at the close of what was a hectic month for markets, WSJ dropped a bombshell of a story: The paper reported that the DoJ has opened an anti-trust investigation of Alphabet Inc., which could "present a major new layer of regulatory scrutiny for the search giant, according to people familiar with the matter." The report was sourced to "people familiar with the matter," but was swiftly corroborated by the New York Times, Bloomberg and others. For months now, the FTC has appeared to be gearing up for a showdown with big tech. The agency - which shares anti-trust authority with the DoJ - has created a new commission that could help undo big-tech tie-ups like Facebook's acquisition of Instagram, and hired lawyers who have advanced new anti-monopoly theories that would help justify the breakup of companies like Amazon. But as it turns out, the Trump administration's first salvo against big tech didn't come from the FTC; instead, this responsibility has been delegated to the DoJ, which has reportedly been tasked with supervising the investigation into Google. That's not super surprising, since the FTC already had its chance to nail Google with an anti-monopoly probe back in 2013. But the agency came up short. From what we can tell, it appears the administration will divvy up responsibility for any future anti-trust investigations between the two agencies, which means the FTC - which is already reportedly preparing to levy a massive fine against Facebook - could end up taking the lead in those cases.
  • Though WSJ didn't specify which aspects of Google's business might come under the microscope, a string of multi-billion-euro fines recently levied by the EU might offer some guidance. The bloc's anti-trust authority, which has been far more eager to take on American tech giants than its American counterpart (for reasons that should be obvious to all), has fined Google over its practice of bundling software with its standard Android license, the way its search engine rankings favor its own product listings, and ways it has harmed competition in the digital advertising market. During the height of the controversy over big tech's abuses of sensitive user data last year, the Verge published a story speculating about how the monopolistic tendencies of each of the dominant Silicon Valley tech giants could be remedied. For Google, the Verge argued, the best remedy would be a ban on acquisitions - a strategy that has been bandied about in Congress.

Shocking Leak Reveals Facebook Leveraged User Data To Reward Friends, Punish Enemies | ... - 0 views

  • As traders focused on bank earnings and the outlook for global growth, NBC News wrested the market's attention back toward Facebook by publishing a report on what appears to be the largest leak of internal documents since the data privacy scandal that has dogged the company for more than a year erupted with the first reports about Cambridge Analytica's 'improper' leveraging of Facebook user data to influence elections.
  • Some 4,000 pages of documents shared with the network news organization by a journalist affiliated with the ICIJ, the same organization that helped bring us the Panama Papers leaks, revealed that Facebook had employed sensitive user data as a bargaining chip to attract major advertisers and close other deals between 2011 and 2015, when the company was struggling to cement its business model following its botched 2012 IPO.
  • Facebook essentially offered companies like Amazon unfettered access to its data in exchange for agreeing to advertise on Facebook's platform, according to the documents, only a small fraction of which have been previously reported on. All of this was happening at a time when the company publicly professed to bee safeguarding user data.
