Google Confirms Android Camera Security Threat: 'Hundreds Of Millions' Of Users Affected - 2 views

  • The security research team at Checkmarx has made something of a habit of uncovering alarming vulnerabilities, with past disclosures covering Amazon’s Alexa and Tinder. However, a  discovery of vulnerabilities affecting Google and Samsung smartphones, with the potential to impact hundreds of millions of Android users, is the biggest to date. What did the researchers discover? Oh, only a way for an attacker to take control of smartphone camera apps and remotely take photos, record video, spy on your conversations by recording them as you lift the phone to your ear, identify your location, and more. All of this performed silently, in the background, with the user none the wiser.

Save Firefox! | Electronic Frontier Foundation - 0 views

  • The World Wide Web Consortium (W3C), once the force for open standards that kept browsers from locking publishers to their proprietary capabilities, has changed its mission. Since 2013, the organization has provided a forum where today's dominant browser companies and the dominant entertainment companies can collaborate on a system to let our browsers control our behavior, rather than the other way. This system, "Encrypted Media Extensions" (EME) uses standards-defined code to funnel video into a proprietary container called a "Content Decryption Module." For a new browser to support this new video streaming standard -- which major studios and cable operators are pushing for -- it would have to convince those entertainment companies or one of their partners to let them have a CDM, or this part of the "open" Web would not display in their new browser. This is the opposite of every W3C standard to date: once, all you needed to do to render content sent by a server was follow the standard, not get permission. If browsers had needed permission to render a page at the launch of Mozilla, the publishers would have frozen out this new, pop-up-blocking upstart. Kiss Firefox goodbye, in other words.
  • The W3C didn't have to do this. No copyright law says that making a video gives you the right to tell people who legally watch it how they must configure their equipment. But because of the design of EME, copyright holders will be able to use the law to shut down any new browser that tries to render the video without their permission. That's because EME is designed to trigger liability under section 1201 of the Digital Millennium Copyright Act (DMCA), which says that removing a digital lock that controls access to a copyrighted work without permission is an offense, even if the person removing the lock has the right to the content it restricts. In other words, once a video is sent with EME, a new company that unlocks it for its users can be sued, even if the users do nothing illegal with that video. We proposed that the W3C could protect new browsers by making their members promise not to use the DMCA to attack new entrants in the market, an idea supported by a diverse group of W3C members, but the W3C executive overruled us saying the work would go forward with no safeguards for future competition. It's even worse than at first glance. The DMCA isn't limited to the USA: the US Trade Representative has spread DMCA-like rules to virtually every country that does business with America. Worse still: the DMCA is also routinely used by companies to threaten and silence security researchers who reveal embarrassing defects in their products. The W3C also declined to require its members to protect security researchers who discover flaws in EME, leaving every Web user vulnerable to vulnerabilities whose disclosure can only safely take place if the affected company decides to permit it.
  • The W3C needs credibility with people who care about the open Web and innovation in order to be viable. They are sensitive to this kind of criticism. We empathize. There are lots of good people working there, people who genuinely, passionately want the Web to stay open to everyone, and to be safe for its users. But the organization made a terrible decision when it opted to provide a home for EME, and an even worse one when it overruled its own members and declined protection for security research and new competitors. It needs to hear from you now. Please share this post, and spread the word. Help the W3C be the organization it is meant to be.

    " Says Cerf, "I'm concerned about a coming digital dark ages." That's why he and some of his fellow inventors of the Internet are joining with a new generation of hackers, archivists, and activists to radically reinvent core technologies that underpin the web. Yes, they want to make the web more secure. They want to make it less vulnerable to censorship. But they also want to make it more resilient to the sands of time."

How an FBI informant orchestrated the Stratfor hack - 0 views

  • Sitting inside a medium-security federal prison in Kentucky, Jeremy Hammond looks defiant and frustrated.  “[The FBI] could've stopped me,” he told the Daily Dot last month at the Federal Correctional Institution, Manchester. “They could've. They knew about it. They could’ve stopped dozens of sites I was breaking into.” Hammond is currently serving the remainder of a 10-year prison sentence in part for his role in one of the most high-profile cyberattacks of the early 21st century. His 2011 breach of Strategic Forecasting, Inc. (Stratfor) left tens of thousands of Americans vulnerable to identity theft and irrevocably damaged the Texas-based intelligence firm's global reputation. He was also indicted for his role in the June 2011 hack of an Arizona state law enforcement agency's computer servers.
  • There's no question of his guilt: Hammond, 29, admittedly hacked into Stratfor’s network and exfiltrated an estimated 60,000 credit card numbers and associated data and millions of emails, information that was later shared with the whistleblower organization WikiLeaks and the hacker collective Anonymous.   Sealed court documents obtained by the Daily Dot and Motherboard, however, reveal that the attack was instigated and orchestrated not by Hammond, but by an informant, with the full knowledge of the Federal Bureau of Investigation (FBI).  In addition to directly facilitating the breach, the FBI left Stratfor and its customers—which included defense contractors, police chiefs, and National Security Agency employees—vulnerable to future attacks and fraud, and it requested knowledge of the data theft to be withheld from affected customers. This decision would ultimately allow for millions of dollars in damages.

Sloppy Cyber Threat Sharing Is Surveillance by Another Name | Just Security - 0 views

  • 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.

Popular Security Software Came Under Relentless NSA and GCHQ Attacks - The Intercept - 0 views

  • 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.”

  • The NSA, like GCHQ, has studied Kaspersky Lab’s software for weaknesses. In 2008, an NSA research team discovered that Kaspersky software was transmitting sensitive user information back to the company’s servers, which could easily be intercepted and employed to track users, according to a draft of a top-secret report. The information was embedded in “User-Agent” strings included in the headers of Hypertext Transfer Protocol, or HTTP, requests. Such headers are typically sent at the beginning of a web request to identify the type of software and computer issuing the request.
  • According to the draft report, NSA researchers found that the strings could be used to uniquely identify the computing devices belonging to Kaspersky customers. They determined that “Kaspersky User-Agent strings contain encoded versions of the Kaspersky serial numbers and that part of the User-Agent string can be used as a machine identifier.” They also noted that the “User-Agent” strings may contain “information about services contracted for or configurations.” Such data could be used to passively track a computer to determine if a target is running Kaspersky software and thus potentially susceptible to a particular attack without risking detection.
  • Another way the NSA targets foreign anti-virus companies appears to be to monitor their email traffic for reports of new vulnerabilities and malware. A 2010 presentation on “Project CAMBERDADA” shows the content of an email flagging a malware file, which was sent to various anti-virus companies by François Picard of the Montréal-based consulting and web hosting company NewRoma. The presentation of the email suggests that the NSA is reading such messages to discover new flaws in anti-virus software. Picard, contacted by The Intercept, was unaware his email had fallen into the hands of the NSA. He said that he regularly sends out notification of new viruses and malware to anti-virus companies, and that he likely sent the email in question to at least two dozen such outfits. He also said he never sends such notifications to government agencies. “It is strange the NSA would show an email like mine in a presentation,” he added.
  • The NSA presentation goes on to state that its signals intelligence yields about 10 new “potentially malicious files per day for malware triage.” This is a tiny fraction of the hostile software that is processed. Kaspersky says it detects 325,000 new malicious files every day, and an internal GCHQ document indicates that its own system “collect[s] around 100,000,000 malware events per day.” After obtaining the files, the NSA analysts “[c]heck Kaspersky AV to see if they continue to let any of these virus files through their Anti-Virus product.” The NSA’s Tailored Access Operations unit “can repurpose the malware,” presumably before the anti-virus software has been updated to defend against the threat.
  • The Project CAMBERDADA presentation lists 23 additional AV companies from all over the world under “More Targets!” Those companies include Check Point software, a pioneering maker of corporate firewalls based Israel, whose government is a U.S. ally. Notably omitted are the American anti-virus brands McAfee and Symantec and the British company Sophos.
  • As government spies have sought to evade anti-virus software, the anti-virus firms themselves have exposed malware created by government spies. Among them, Kaspersky appears to be the sharpest thorn in the side of government hackers. In the past few years, the company has proven to be a prolific hunter of state-sponsored malware, playing a role in the discovery and/or analysis of various pieces of malware reportedly linked to government hackers, including the superviruses Flame, which Kaspersky flagged in 2012; Gauss, also detected in 2012; Stuxnet, discovered by another company in 2010; and Regin, revealed by Symantec. In February, the Russian firm announced its biggest find yet: the “Equation Group,” an organization that has deployed espionage tools widely believed to have been created by the NSA and hidden on hard drives from leading brands, according to Kaspersky. In a report, the company called it “the most advanced threat actor we have seen” and “probably one of the most sophisticated cyber attack groups in the world.”
  • Hacks deployed by the Equation Group operated undetected for as long as 14 to 19 years, burrowing into the hard drive firmware of sensitive computer systems around the world, according to Kaspersky. Governments, militaries, technology companies, nuclear research centers, media outlets and financial institutions in 30 countries were among those reportedly infected. Kaspersky estimates that the Equation Group could have implants in tens of thousands of computers, but documents published last year by The Intercept suggest the NSA was scaling up their implant capabilities to potentially infect millions of computers with malware. Kaspersky’s adversarial relationship with Western intelligence services is sometimes framed in more sinister terms; the firm has been accused of working too closely with the Russian intelligence service FSB. That accusation is partly due to the company’s apparent success in uncovering NSA malware, and partly due to the fact that its founder, Eugene Kaspersky, was educated by a KGB-backed school in the 1980s before working for the Russian military.
  • Kaspersky has repeatedly denied the insinuations and accusations. In a recent blog post, responding to a Bloomberg article, he complained that his company was being subjected to “sensationalist … conspiracy theories,” sarcastically noting that “for some reason they forgot our reports” on an array of malware that trace back to Russian developers. He continued, “It’s very hard for a company with Russian roots to become successful in the U.S., European and other markets. Nobody trusts us — by default.”

How to Protect Yourself from NSA Attacks on 1024-bit DH | Electronic Frontier Foundation - 0 views

  • In a post on Wednesday, researchers Alex Halderman and Nadia Heninger presented compelling research suggesting that the NSA has developed the capability to decrypt a large number of HTTPS, SSH, and VPN connections using an attack on common implementations of the Diffie-Hellman key exchange algorithm with 1024-bit primes. Earlier in the year, they were part of a research group that published a study of the Logjam attack, which leveraged overlooked and outdated code to enforce "export-grade" (downgraded, 512-bit) parameters for Diffie-Hellman. By performing a cost analysis of the algorithm with stronger 1024-bit parameters and comparing that with what we know of the NSA "black budget" (and reading between the lines of several leaked documents about NSA interception capabilities) they concluded that it's likely NSA has been breaking 1024-bit Diffie-Hellman for some time now. The good news is, in the time since this research was originally published, the major browser vendors (IE, Chrome, and Firefox) have removed support for 512-bit Diffie-Hellman, addressing the biggest vulnerability. However, 1024-bit Diffie-Hellman remains supported for the forseeable future despite its vulnerability to NSA surveillance. In this post, we present some practical tips to protect yourself from the surveillance machine, whether you're using a web browser, an SSH client, or VPN software.
