That LIFX Smart Lightbulb Hack Wasn’t Easy

If you’ve been following your Internet of Things security news, you probably read about the latest hack of a consumer-oriented ‘smart home’ device: Context Information Security’s analysis of security holes in LIFX-brand smart light bulbs. The top line on this is scary enough. As The Register reported: researchers at Context discovered that, by gaining access to a “master bulb” in LIFX deployments, they could control all connected lightbulbs and expose user network configurations. That’s scary – and recalls research on hacking Philips HUE light bulbs that was published last year. But read down in the Context research and you’ll realize that, while the LIFX technology wasn’t perfect, the job of hacking the technology wasn’t child’s play, either. LIFX connected its smart bulbs using a 6LoWPAN-based mesh network. The company made the mistake of transmitting most bulb-bulb communications in the clear, which made analyzing traffic sent between master- and slave bulbs easy. Context researchers found […]

FDA: Regulators Can’t Scale To Police Mobile Health Apps

A senior advisor to the U.S. Food and Drug Administration (FDA) tossed cold water on speculation that the Agency might try to police mobile health and wellness applications, saying the FDA couldn’t possibly scale up to meet the challenge of policing the hundreds of new apps appearing every month. Correction: The article was changed to clarify Mr. Patel’s comments. He was not responding to a direct question about the FDA setting up an office to regulate mobile health applications. He was commenting on the possibility of creating a platform to evaluate and rate mobile health applications.  Also, he said “It’s not do-able,” not “it’s not possible.” We apologize for any confusion created by the article. – PFR July 10, 2014. The sheer pace of innovation in the mobile health application space and the numbers of such applications already available on mobile marketplaces like the iTunes App Store and Google Play mean that many mobile health applications will escape scrutiny by federal […]

Is HyperCat An IoT Silo Buster? | ZDNet

Steve Ranger over at ZDNet has an interesting write-up on HyperCat, a UK-funded data sharing open specification for Internet of Things devices. The new specifications has the backing (or at least interest) of major players and could become an alternative to proprietary standards such as Apple’s HomeKit or Google Nest. HyperCat is described as an “open, lightweight, JSON-based hypermedia catalogue” that is designed to “expose information about IoT assets over the web.” The goal is to provide a set of open APIs and data formats that startups and other smaller firms can use to built ecosystems of connected objects. Smart devices are typically developed using common technologies and platforms: RESTful APIs, JSON (Javascript Object Notation) for data formatting and HTTP (or secure HTTP) as the main communications protocol. However, the Internet of Things is badly “silo’d” – meaning that interoperability between IoT devices happens only when those smart devices happen to use the […]

Infographic: A Heartbleed Disclosure Timeline (Secunia)

The dangerous security hole in OpenSSL known as “Heartbleed” has (mostly) faded from the headlines, but that doesn’t mean it isn’t still dangerous. As this blog has noted, the Heartbleed vulnerability was patched quickly on major platforms like Apache and nginx and by high profile service providers like Google and Facebook. But it still has a long tail of web applications that aren’t high risk (i.e. directly reachable via the Internet) and embedded devices that use OpenSSL or its various components. As the folks over at Acunetix note in a blog post today, hundreds of other services, application software and operating systems make use of OpenSSL for purposes that might be entirely unrelated to delivering pages over HTTPS. This includes all the email servers (using SMTP, POP and IMAP protocols), FTP servers, chat servers (XMPP protocol), virtual private networks (SSL VPNs), and network appliances that use OpenSSL or its components. The number of systems vulnerable to […]

IPMI’s Inconvenient Truth: A Conversation With Dan Farmer

The work of brilliant computer security researchers often borders on a kind of madness. After all, it takes dedication and a certain amount of monomania to dig through the mush of disassembled source code or the output of application fuzzers and find the one software vulnerabilities – or chain of vulnerabilities – that might lead to a successful attack. Often, this work puts you at odds with what most of us consider “the real world.” Notably: the well-respected researcher Dragos Ruiu had many in the security community wondering about his sanity after he sounded the alarm about a super stealthy piece of BIOS malware he dubbed “BadBIOS” that seemed to be everywhere and nowhere, all at once. Dan Farmer finds himself in a similar position as he continues to sound alarms about the security threat posed by insecure implementations of the Intelligent Platform Management Interface (IPMI)– a ubiquitous protocol used to do remote […]
