"TrustyCon" security counter-convention planned for RSA refusniks - 0 views

  •  
    The RSA concerns started with documents leaked by Edward Snowden and published by the New York Times in December. These indicated that the NSA had worked with the National Institute of Standards and Technology to create a "backdoor" in the Dual Elliptic Curve Deterministic Random Bit Generator (Dual_EC_DRBG), a pseudorandom number generator designated as a standard for encryption. According to the documents, in 2004-even before NIST approved it as a standard-the NSA paid RSA $10 million to use Dual EC DRGB as part of its RSA BSAFE cryptographic library. This meant that much of the encryption software sold by RSA would allow the NSA to break the encryption using the known backdoor

Plugging the CSS History Leak at Mozilla Security Blog - 0 views

  • History Sniffing
  • Links can look different on web sites based on whether or not you’ve visited the page they reference.
  • The problem is that appearance can be detected by the page showing you links, cluing the page into which of the presented pages you’ve been to. The result: not only can you see where you’ve been, but so can the web site!
  • ...18 more annotations...
  • The most obvious fix is to disable different styles for visited versus unvisted links, but this would be employed at the expense of utility: while sites can no longer figure out which links you’ve clicked, neither can you.
  • David Baron has implemented a way to help keep users’ data private while minimizing the effect on the web, and we are deploying it to protect our users.
  • The biggest threats here are the high-bandwidth techniques, or those that extract lots of information from users’ browsers quickly.
  • The JavaScript function getComputedStyle() and its related functions are fast and can be used to guess visitedness at hundreds of thousands of links per minute.
  • we’re approaching the way we style links in three fairly subtle ways:
  • Change 1: Layout-Based Attacks
  • First of all, we’re limiting what types of styling can be done to visited links to differentiate them from unvisited links.
  • can only be different in color
  • the CSS 2.1 specification takes into consideration how visited links can be abused:
  • implement other measures to preserve the user’s privacy while rendering visited and unvisited links differently
  • Change 2: Some Timing Attacks
  • we are changing some of the guts of our layout engine to provide a fairly uniform flow of execution to minimize differences in layout time for visited and unvisited links.
  • when the link is styled, the appropriate set of styles is chosen making the code paths for visited and unvisited links essentially the same length.
  • Change 3: Computed Style Attacks
  • JavaScript is not going to have access to the same style data it used to.
  • Firefox will give it unvisited style values.
  • it’s the right trade-off to be sure we protect our users’ privacy.
  • fixing CSS history sniffing will not block all of these leaks. But we believe it’s important to stop the scariest, most effective history attacks any way we can since it will be a big win for users’ privacy.

Web Posts May Make You Vulnerable To Crime : NPR - 0 views

  •  
    It's fun to brag when you're at a great bar or going off on vacation. Social networking sites and location-based apps have made it easy to broadcast that kind of information to your friends. The problem is that you may not just be making your friends jealous, but supplying criminals with useful information as well. A new Web site called PleaseRobMe.com has drawn attention to the issue by repurposing posts from foursquare, a social networking site that lets people share the latest about their whereabouts. PleaseRobMe demonstrates that it's easy for anyone to find out you're not at home - and therefore, are presenting an "opportunity" for burglary. "There are physical and economic safety risks when you're publicizing to the world where you are," says Kevin Bankston, a senior staff attorney with the Electronic Frontier Foundation. "It's obviously a treasure trove of information for criminals. PleaseRobMe is a good demonstration of how easy it is."

FTC warns firms, organizations of widespread data breach - 0 views

  • The FTC declined to identify the companies or organizations involved, but said they were both "private and public entities, including schools and local governments." The companies and organizations ranged in size from "businesses with as few as eight employees to publicly held corporations employing tens of thousands," the FTC said in a statement. It said sensitive data about customers and employees had been shared from the computer networks of the companies and organizations and made available on Internet peer-to-peer (P2P) file-sharing networks. The information was accessible to "any users of those networks, who could use it to commit identity theft or fraud," the FTC said. "Unfortunately, companies and institutions of all sizes are vulnerable to serious P2P-related breaches, placing consumers' sensitive information at risk," FTC chairman Jon Leibowitz said. "For example, we found health-related information, financial records, and drivers' license and social security numbers -- the kind of information that could lead to identity theft," Leibowitz said.

Unintended Consequences: Twelve Years under the DMCA | Electronic Frontier Foundation - 0 views

  • The DMCA Chills Free Expression and Scientific Research. Experience with section 1201 demonstrates that it is being used to stifle free speech and scientific research. The lawsuit against 2600 magazine, threats against Princeton Professor Edward Felten's team of researchers, and prosecution of Russian programmer Dmitry Sklyarov have chilled the legitimate activities of journalists, publishers, scientists, students, programmers, and members of the public. The DMCA Jeopardizes Fair Use. By banning all acts of circumvention, and all technologies and tools that can be used for circumvention, the DMCA grants to copyright owners the power to unilaterally eliminate the public's fair use rights. Already, the movie industry's use of encryption on DVDs has curtailed consumers' ability to make legitimate, personal-use copies of movies they have purchased. The DMCA Impedes Competition and Innovation. Rather than focusing on pirates, some have wielded the DMCA to hinder legitimate competitors. For example, the DMCA has been used to block aftermarket competition in laser printer toner cartridges, garage door openers, and computer maintenance services. Similarly, Apple has used the DMCA to tie its iPhone and iPod devices to Apple's own software and services. The DMCA Interferes with Computer Intrusion Laws. Further, the DMCA has been misused as a general-purpose prohibition on computer network access, a task for which it was not designed and to which it is ill-suited. For example, a disgruntled employer used the DMCA against a former contractor for simply connecting to the company's computer system through a virtual private network ("VPN").
  •  
    Since they were enacted in 1998, the "anti-circumvention" provisions of the Digital Millennium Copyright Act ("DMCA"), codified in section 1201 of the Copyright Act, have not been used as Congress envisioned. Congress meant to stop copyright infringers from defeating anti-piracy protections added to copyrighted works and to ban the "black box" devices intended for that purpose.1 In practice, the anti-circumvention provisions have been used to stifle a wide array of legitimate activities, rather than to stop copyright infringement. As a result, the DMCA has developed into a serious threat to several important public policy priorities:

Microsoft Recruited Top Notch Guns for Waledac Takedown - CIO.com - Business Technology... - 0 views

  • Microsoft revealed on Wednesday that it gained a court order that compelled VeriSign, the .com registry, to remove 277 ".com" names from its rolls, effectively cutting off communication between the Waledac's controllers and their infected machines. The legal action is unprecedented at the domain name level, said Andre' M. DiMino, co-founder of The Shadowserver Foundation, a group that tracks botnets and helped take down Waledac. In June 2009, a federal court ordered the shutdown of 3FN, a rogue ISP supplying connectivity to botnets such as Pushdo and Mega-D, but this appears to be the first major action at the domain-name level. "It's definitely pretty groundbreaking," DiMino said. "To disable and disrupt a botnet at this level is really pulling the weed out by the root." But behind the scenes, Microsoft's legal action was just one component of a synchronized campaign to bring down Waledac. Last year, researchers with the University of Mannheim in Germany and Technical University Vienna in Austria published a research paper showing how it was possible to infiltrate and control the Waledec botnet. They had studied Waledac's complicated peer-to-peer communication mechanism. Microsoft -- which was annoyed by Waledec due to its spamming of Hotmail accounts -- contacted those researchers about two weeks ago to see if they could perform their attack for real, according one of the University of Mannheim researchers, who did not want to be identified. "They asked me if there was also a way besides taking down those domains of redirecting the command-and-control traffic," said the Mannheim researcher. Waledac distributes instructions through command-and-control servers that work with a peer-to-peer system. Led by a researcher who did his bachelor thesis on Waledac, the action began early this week. "This was more or less an aggressive form of what we did before," the Mannheim researcher said. "We disrupted the peer-to-peer layer to redirect traffic not to botmaster servers but to our servers." At the same time, Microsoft's legal efforts brought down domain names that were used to send new instructions to drones. The result has been dramatic: Up to 90 percent of the infected machines, which amount to at least 60,000 computers, are now controlled by researchers, half of which are in the U.S. and Europe and the rest scattered around the globe.
  •  
    Four days ago, top-notch computer security researchers launched an assault on Waledac, a highly sophisticated botnet responsible for spreading spam and malicious software. As of Thursday, more than 60,000 PCs worldwide that have been infected with malicious code are now under the control of researchers, marking the effort one of the most highly successful coordinated against organized cybercrime.

Hold vendors liable for buggy software, group says - 0 views

  • "The only way programming errors can be eradicated is by making software development organizations legally liable for the errors," he said. SANS and Mitre, a Bedford, Mass.-based government contractor, also released their second annual list of the top 25 security errors made by programmers. The authors said those errors have been at the root of almost every major type of cyberattack, including the recent hacks of Google and numerous utilities and government agencies. According to the list, the most common mistakes continue to involve SQL injection errors, cross-site scripting flaws and buffer overflow vulnerabilities. All three have been well-known problems for
  •  
    A coalition of security experts from more than 30 organizations is urging enterprises to exert more pressure on software vendors to ensure that they use secure code development practices. The group, led by the SANS Institute and Mitre Corp., offered enterprises recent hacks of Google draft contract language that would require vendors to adhere to a strict set of security standards for software development. In essence, the terms would make vendors liable for software defects that lead to security breaches. "Nearly every attack is enabled by [programming] mistakes that provide a handhold for attackers," said Alan Paller, director of research at SANS, a security training and certification group.
  •  
    Of course, a more general way to address this and other "business" generated problems / abuses (like expensive required "arbitration" by companies owned and in bed with the companies requiring the arbitration!), is to FORBID contract elements that effectively strip any party of certain "rights" (like the right to sue for defectives; the right to freedom of speech; the right to warranty protections; the right to hold either party to public or published promises / representations, etc.). Basically, by making LYING and DECEIT and NEGLIGENCE liability and culpability unrestricted. Or will we hear / be told that being honest and producing a quality product is "anti-business"? What!? Is this like, if I can't lie and cheat being in business isn't worth it!? If that is true, then those parties and businesses could just as well "go away"! Just as "conservatives" say other criminals like that should. One may have argued that the software industry would never have "gotten off the ground" (at least, as fast as it did) if such strict liability had been enforced (as say, was eventually and is more often applied to physical building and their defects / collapses). That is, that the EULAs and contracts typically accompanying software ("not represented as fit for any purpose" more or less!) had been restricted. On the other hand, we might have gotten software somewhat slower but BETTER - NOT being associated with or causing the BILLIONS of dollars in losses due to bugs, security holes, etc. Others will rail that this will merely "make lawyers richer". So what if it will? As long as government isn't primarily "on the side" of the majority of the people (you know, like a "democracy" should be), then being able to get a individual "hired gun" is one of the only ways for the "little guy" to effectively defend themselves from corporate criminals and other "special interest" elites.
