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 […]

Update: Another IPMI Mishap? Researcher Claims Supermicro Devices Vulnerable

There’s more bad news for companies that rely on the Intelligent Platform Management Interface (IPMI) to manage servers and other hardware in their IT environments. Specifically: researcher Zachary Wikholm over at Cari.net has published evidence of what he says is a head-slapping vulnerability affecting devices that use IPMI Base Management Controllers (BMCs) made by the firm SuperMicro. According to Wikholm, servers equipped with Supermicro BMCs store a password file, PSBlock, in plain text and – making matters worse- leave it open to the world on port 49152. “You can quite literally download the BMC password file from any UPnP enabled Supermicro motherboard running IPMI on a public interface,” he wrote. Baseboard Management Controllers (BMCs) are small, embedded systems attached to a system’s motherboard that manage IPMI communications. Wikholm says that Supermicro has fixed the problem in the latest version of its IPMI firmware. However, companies are often reluctant to flash […]

UEFI: Security, BIOS and the Internet of Things

One of the notable trends in recent years has been the drive, among malicious actors, to compromise devices in new- and hard-to-detect ways. An area of interest and exploration is malicious software that can attack a computer’s BIOS – the small bit of code that runs when a computing device is first powered on. BIOS malware is so powerful because it offers adversaries the possibility of getting a foothold on systems prior to an operating system and the security features- and applications that run there. Successful BIOS attacks give attackers almost total control over the system they are installed on. BIOS malware isn’t a new idea. In fact, it has been around since the late 1990s, when the Chernobyl Virus was identified. That virus could wipe a machine’s BIOS, a well as the contents of its hard drive. But BIOS threats have been getting more attention lately. Proof of concept malware appeared as recently […]

IPMI Insecurity Affects 200k Systems

It has been almost a year since security researcher Dan Farmer first warned of the danger posed by Intelligent Platform Management Interface (IPMI) – a ubiquitous protocol used to do remote management of servers. According to a new report, however, that warning went unheeded. Writing last week (PDF), Farmer said that a world-wide scan for systems using the Intelligent Platform Management Interface (IPMI) protocol identified over 230,000 Baseboard Management Controllers (BMCs) exposed to the Internet. As many as 90% of the exposed systems could be compromised by exploiting what Farmer characterized as “basic configuration and protocol weaknesses.” Even more worrying, the 230,000 systems that are Internet accessible are probably just a fraction of all the vulnerable systems that might be attacked, with many deployed on (hackable) corporate and private networks. Farmer is reiterating calls for public and private sector organizations to wake up to the dangers posed by IPMI. Hackers who are able to compromise Baseboard Management […]

Car Makers, Suppliers Going Their Own Way On Security

I was surprised to see a big feature story over at CNN.com this morning – given that the security of connected vehicles has no obvious link to LA Clippers owner Don Sterling, the on-going shakeup at the Veterans Administration or a tornado or other natural disaster. Still – there it is: “Your car is a giant computer – and it can be hacked.” The feature, by Jose Pagliery is solid enough – though it doesn’t break much new ground. He mentions the research by Chris Valasek and Charlie Miller at The Black Hat Briefings last year. He also talks to the folks over at Security Innovation. [Want more on security and connected vehicles? Check out our video: Insecure At Any Speed: Are Automakers Failing The Software Crash Test? ] The big take-away: automobiles are rife with old and outdated software and hardware, much of it lacking even basic security features  like secure communications […]
