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 […]

Industrial Control Vendors Identified In Dragonfly Attack

Two of the three vendors who were victims of a targeted malware attack dubbed ‘Dragonfly’ by the security firm Symantec have been identified by industrial control system security experts. Writing on Tuesday, Dale Peterson of the firm Digitalbond identified the vendors as MB Connect Line, a German maker of industrial routers and remote access appliances and eWon, a Belgian firm that makes virtual private network (VPN) software that is used to access industrial control devices like programmable logic controllers. Peterson has also identified the third vendor, identified by F-Secure as a Swiss company, but told The Security Ledger that he cannot share the name of that firm. The three firms, which serve customers in industry, including owners of critical infrastructure, were the subject of a warning from the Department of Homeland Security. DHS’s ICS CERT, the Industrial Control Systems Computer Emergency Response Team, said it was alerted to compromises of the vendors’ by researchers […]

DHS Warns Energy Firms Of Malware Used In Targeted Attacks

The Department of Homeland Security warned firms in the energy sector about new, targeted malware infecting industrial control systems and stealing data. DHS’s ICS CERT, the Industrial Control Systems Computer Emergency Response Team, said it is analyzing malware associated with an ICS-focused malware campaign. The malicious software, dubbed “Havex” that was being spread by way of phishing emails and so-called “watering hole” attacks that involved compromises of ICS vendor web sites. DHS was alerted to the attacks by researchers at the security firms Symantec (which dubbed the malware campaign “Dragonfly”) and F-Secure (“Havex”) -a remote access trojan (or RAT) that also acts as an installer (or “downloader”) – fetching other malicious applications to perform specific tasks on compromised networks. One of those additional payloads is a Trojan Horse program dubbed Karagany (by Symantec) that has been liked to prior attacks on energy firms. According to Symantec, the malware targeted energy grid operators, major electricity generation firms, […]

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 […]

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 […]
