Intel Promotes ‘Trustlets’ To Secure Embedded Devices

The integrity of data stored on- and transmitted between Internet-connected embedded devices is one of the biggest technical hurdles standing in the way of widespread adoption of Internet of Things technology. For one thing: embedded devices like wearable technology and “smart” infrastructure are often deployed on simple, inexpensive and resource constrained hardware. Unlike laptops or even smart phones, these are purpose-built devices that, by design, run for long periods in remote deployments, with extremely constrained features and low power consumption that is the result of limited processing power and memory. [Read Security Ledger’s coverage of connected vehicles.] Now Intel is promoting a platform that it says can bridge the gap and provide robust security features even for resource-constrained Internet of Things devices like wearables and connected vehicles. Back in April, the Intel Labs  unveiled the results of joint research with Technische Universität Darmstadt in Germany. The researchers have developed a platform, dubbed TrustLite […]

Google Warns Of Dodgy Digital Certificates Issued By India

Beware of Google domains bearing gifts – especially gifts from India. On Tuesday, Google’s Adam Langley took to the company’s security blog to warn about unauthorized digital certificates that have been issued by India’s National Informatics Centre (NIC) and used to vouch for “several Google domains.” Google notified the NIC, as well as India’s Controller of Certifying Authorities (or CCA) and Microsoft about the discovery and the certificates have been revoked, Langley said. As Cory Doctorow noted over at BoingBoing.net, most operating system vendors and browser makers don’t trust NIC-issued certificates as a matter of course. However, NIC holds intermediate CA (certificate authority) certificates that are trusted by India’s CCA, and CCA-trusted certificates are included in Microsoft’s Root Store, meaning applications running on Windows as well as Microsoft’s Internet Explorer web browser would have trusted the bogus NIC certificates. Google said that Chrome users on Windows would not have been victims of the […]

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 […]

Code Spaces Probably A ‘Target of Opportunity’

The spectacular collapse this week of Code Spaces, a cloud-based code repository, may have been the result of a an unspectacular “opportunistic” hack, rather than a targeted operation, according to one cloud security expert. The sudden demise of the online application repository has sent shock waves through the tech industry, laying bare what some say are lax practices among many cloud-based application and infrastructure providers. But the attack itself was almost certainly the result of a larger, indiscriminate cyber criminal campaign, said Jeff Schilling, the Chief Security Officer of Firehost, a Texas-based secure cloud provider. “This is something we pretty frequently: companies get held ransom with a DDoS attack, and if that doesn’t work, (the attackers) will resort to doing other things,” Schilling told The Security Ledger. But Code Spaces almost certainly wasn’t the only company the extortionists worked on, Schilling said. Instead, the company was likely caught up in a wide net […]

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 […]
