Comcast has been conducting IPv6 technical trials in our production network for more than a year, and we've been working diligently on IPv6 deployment for over 6 years. After so many years of challenging preparatory work, significant technology investment, internal skills development, and close collaboration with our technology partners, I am incredibly pleased to announce that we've achieved another critical milestone in our transition to IPv6 — we have started the pilot market deployment of IPv6 to customers in selected markets! We're now the first large ISP in North America to start deploying IPv6. This is a significant milestone not just inside our own company but also in the industry, particularly given the chicken and egg relationship between the availability of content and software that supports IPv6 and the deployment of IPv6 to end users.

This first phase will support certain types of directly connected CPE, where a single computer is connected directly to a cable modem. Subsequent phases in 2011 and 2012 will support home gateway devices and variable length prefixes. Critically, our approach is "native dual stack" which means customers will get both IPv4 and IPv6 addresses. Some other ISPs that are less prepared may be using tunneling or large scale NAT in the network. Those approaches are likely to result in some applications (such as some real-time applications) breaking or seeming slow. Native dual stack, the approach we are using, avoids breaking or slowing applications and maintains a better and faster broadband Internet experience. Our customers buy Xfinity Internet service in large part for our great speeds, and they can rest assured that they won't have to slow down as the world transitions to IPv6, as we've "just said no to NAT" in this phase of our IPv6 transition.

. In this research paper we hope to explain that the bitcoin currency itself is ‘just’ the next phase in the evolution of money – from dumb to smart money. It’s the underlying platform, the Bitcoin protocol aka Bitcoin 2.0, that holds the real transformative power. That is where the revolution starts. According to our research there are several reasons why this new technology is going to disrupt our economy and society as we have never experienced before:

The secretive British spy agency GCHQ has developed covert tools to seed the internet with false information, including the ability to manipulate the results of online polls, artificially inflate pageview counts on web sites, “amplif[y]” sanctioned messages on YouTube, and censor video content judged to be “extremist.” The capabilities, detailed in documents provided by NSA whistleblower Edward Snowden, even include an old standby for pre-adolescent prank callers everywhere: A way to connect two unsuspecting phone users together in a call.

he “tools” have been assigned boastful code names. They include invasive methods for online surveillance, as well as some of the very techniques that the U.S. and U.K. have harshly prosecuted young online activists for employing, including “distributed denial of service” attacks and “call bombing.” But they also describe previously unknown tactics for manipulating and distorting online political discourse and disseminating state propaganda, as well as the apparent ability to actively monitor Skype users in real-time—raising further questions about the extent of Microsoft’s cooperation with spy agencies or potential vulnerabilities in its Skype’s encryption. Here’s a list of how JTRIG describes its capabilities: • “Change outcome of online polls” (UNDERPASS) • “Mass delivery of email messaging to support an Information Operations campaign” (BADGER) and “mass delivery of SMS messages to support an Information Operations campaign” (WARPARTH) • “Disruption of video-based websites hosting extremist content through concerted target discovery and content removal.” (SILVERLORD)

• “Active skype capability. Provision of real time call records (SkypeOut and SkypetoSkype) and bidirectional instant messaging. Also contact lists.” (MINIATURE HERO) • “Find private photographs of targets on Facebook” (SPRING BISHOP) • “A tool that will permanently disable a target’s account on their computer” (ANGRY PIRATE) • “Ability to artificially increase traffic to a website” (GATEWAY) and “ability to inflate page views on websites” (SLIPSTREAM) • “Amplification of a given message, normally video, on popular multimedia websites (Youtube)” (GESTATOR) • “Targeted Denial Of Service against Web Servers” (PREDATORS FACE) and “Distributed denial of service using P2P. Built by ICTR, deployed by JTRIG” (ROLLING THUNDER)

The Obama administration fought a legal battle against Google to secretly obtain the email records of a security researcher and journalist associated with WikiLeaks. Newly unsealed court documents obtained by The Intercept reveal the Justice Department won an order forcing Google to turn over more than one year’s worth of data from the Gmail account of Jacob Appelbaum (pictured above), a developer for the Tor online anonymity project who has worked with WikiLeaks as a volunteer. The order also gagged Google, preventing it from notifying Appelbaum that his records had been provided to the government. The surveillance of Appelbaum’s Gmail account was tied to the Justice Department’s long-running criminal investigation of WikiLeaks, which began in 2010 following the transparency group’s publication of a large cache of U.S. government diplomatic cables. According to the unsealed documents, the Justice Department first sought details from Google about a Gmail account operated by Appelbaum in January 2011, triggering a three-month dispute between the government and the tech giant. Government investigators demanded metadata records from the account showing email addresses of those with whom Appelbaum had corresponded between the period of November 2009 and early 2011; they also wanted to obtain information showing the unique IP addresses of the computers he had used to log in to the account.

The Justice Department argued in the case that Appelbaum had “no reasonable expectation of privacy” over his email records under the Fourth Amendment, which protects against unreasonable searches and seizures. Rather than seeking a search warrant that would require it to show probable cause that he had committed a crime, the government instead sought and received an order to obtain the data under a lesser standard, requiring only “reasonable grounds” to believe that the records were “relevant and material” to an ongoing criminal investigation. Google repeatedly attempted to challenge the demand, and wanted to immediately notify Appelbaum that his records were being sought so he could have an opportunity to launch his own legal defense. Attorneys for the tech giant argued in a series of court filings that the government’s case raised “serious First Amendment concerns.” They noted that Appelbaum’s records “may implicate journalistic and academic freedom” because they could “reveal confidential sources or information about WikiLeaks’ purported journalistic or academic activities.” However, the Justice Department asserted that “journalists have no special privilege to resist compelled disclosure of their records, absent evidence that the government is acting in bad faith,” and refused to concede Appelbaum was in fact a journalist. It claimed it had acted in “good faith throughout this criminal investigation, and there is no evidence that either the investigation or the order is intended to harass the … subscriber or anyone else.” Google’s attempts to fight the surveillance gag order angered the government, with the Justice Department stating that the company’s “resistance to providing the records” had “frustrated the government’s ability to efficiently conduct a lawful criminal investigation.”

The Justice Department wanted to keep the surveillance secret largely because of an earlier public backlash over its WikiLeaks investigation. In January 2011, Appelbaum and other WikiLeaks volunteers’ – including Icelandic parlimentarian Birgitta Jonsdottir – were notified by Twitter that the Justice Department had obtained data about their accounts. This disclosure generated widepread news coverage and controversy; the government says in the unsealed court records that it “failed to anticipate the degree of  damage that would be caused” by the Twitter disclosure and did not want to “exacerbate this problem” when it went after Appelbaum’s Gmail data. The court documents show the Justice Department said the disclosure of its Twitter data grab “seriously jeopardized the [WikiLeaks] investigation” because it resulted in efforts to “conceal evidence” and put public pressure on other companies to resist similar surveillance orders. It also claimed that officials named in the subpeona ordering Twitter to turn over information were “harassed” after a copy was published by Intercept co-founder Glenn Greenwald at Salon in 2011. (The only specific evidence of the alleged harassment cited by the government is an email that was sent to an employee of the U.S. Attorney’s office that purportedly said: “You guys are fucking nazis trying to controll [sic] the whole fucking world. Well guess what. WE DO NOT FORGIVE. WE DO NOT FORGET. EXPECT US.”)

1. Executive Summary Ahmed Mansoor is an internationally recognized human rights defender, based in the United Arab Emirates (UAE), and recipient of the Martin Ennals Award (sometimes referred to as a “Nobel Prize for human rights”).  On August 10 and 11, 2016, Mansoor received SMS text messages on his iPhone promising “new secrets” about detainees tortured in UAE jails if he clicked on an included link. Instead of clicking, Mansoor sent the messages to Citizen Lab researchers.  We recognized the links as belonging to an exploit infrastructure connected to NSO Group, an Israel-based “cyber war” company that sells Pegasus, a government-exclusive “lawful intercept” spyware product.  NSO Group is reportedly owned by an American venture capital firm, Francisco Partners Management. The ensuing investigation, a collaboration between researchers from Citizen Lab and from Lookout Security, determined that the links led to a chain of zero-day exploits (“zero-days”) that would have remotely jailbroken Mansoor’s stock iPhone 6 and installed sophisticated spyware.  We are calling this exploit chain Trident.  Once infected, Mansoor’s phone would have become a digital spy in his pocket, capable of employing his iPhone’s camera and microphone to snoop on activity in the vicinity of the device, recording his WhatsApp and Viber calls, logging messages sent in mobile chat apps, and tracking his movements.   We are not aware of any previous instance of an iPhone remote jailbreak used in the wild as part of a targeted attack campaign, making this a rare find.

The Trident Exploit Chain: CVE-2016-4657: Visiting a maliciously crafted website may lead to arbitrary code execution CVE-2016-4655: An application may be able to disclose kernel memory CVE-2016-4656: An application may be able to execute arbitrary code with kernel privileges Once we confirmed the presence of what appeared to be iOS zero-days, Citizen Lab and Lookout quickly initiated a responsible disclosure process by notifying Apple and sharing our findings. Apple responded promptly, and notified us that they would be addressing the vulnerabilities. We are releasing this report to coincide with the availability of the iOS 9.3.5 patch, which blocks the Trident exploit chain by closing the vulnerabilities that NSO Group appears to have exploited and sold to remotely compromise iPhones. Recent Citizen Lab research has shown that many state-sponsored spyware campaigns against civil society groups and human rights defenders use “just enough” technical sophistication, coupled with carefully planned deception. This case demonstrates that not all threats follow this pattern.  The iPhone has a well-deserved reputation for security.  As the iPhone platform is tightly controlled by Apple, technically sophisticated exploits are often required to enable the remote installation and operation of iPhone monitoring tools. These exploits are rare and expensive. Firms that specialize in acquiring zero-days often pay handsomely for iPhone exploits.  One such firm, Zerodium, acquired an exploit chain similar to the Trident for one million dollars in November 2015. The high cost of iPhone zero-days, the apparent use of NSO Group’s government-exclusive Pegasus product, and prior known targeting of Mansoor by the UAE government provide indicators that point to the UAE government as the likely operator behind the targeting. Remarkably, this case marks the third commercial “lawful intercept” spyware suite employed in attempts to compromise Mansoor.  In 2011, he was targeted with FinFisher’s FinSpy spyware, and in 2012 he was targeted with Hacking Team’s Remote Control System.  Both Hacking Team and FinFisher have been the object of several years of revelations highlighting the misuse of spyware to compromise civil society groups, journalists, and human rights workers.
