Update: Another IPMI Mishap? Researcher Claims Supermicro Devices Vulnerable

June 20, 2014 Paul Roberts

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 […]

Internet of Things to Increase Shortage of Security Professionals

June 17, 2014 Paul Roberts

The tech publication eWeek has an interesting interview with Sujata Ramamoorthy, the director for global information security for Cisco’s Threat Response, Intelligence, and Development (TRIAD) group about the impact of Internet of Things technology on the (already painful) shortage of IT security workers. According to Ramamoorthy, adoption of Internet of Things technologies and platforms will exacerbate the IT security worker shortage. “These trends are what are fueling the need for additional security skills in the industry, and because the networks themselves are getting more complex, the applications communicating over them are getting more complex,” she told eWeek reporter Rob Lemos. The increasing complexity of information infrastructure in IoT deployments, an explosion in the number of connected endpoints and a corresponding lack of visibility into cloud services all make the shortage of corporate security experts more critical, Ramamoorthy said. Already there is an estimated 1 million information-security staff and manager shortage globally, according […]

Wired Imagines Our Dystopian Connected Home Future

June 16, 2014 Paul Roberts

Over at Wired.com, the ever-provocative Matt Honan has a great little thought exercise on the “nightmare” that could come from connected home technology gone wrong. His piece, The Nightmare on Connected Home Street, is a first person narrative of a man who wakes up to discover he’s transformed into a cockroach inhabiting a virus infected home. “Technically it’s malware. But there’s no patch yet, and pretty much everyone’s got it. Homes up and down the block are lit up, even at this early hour. Thankfully this one is fairly benign. It sets off the alarm with music I blacklisted decades ago on Pandora. It takes a picture of me as I get out of the shower every morning and uploads it to Facebook. No big deal.” The story goes on to chronicle some of the other dystopian features of connected home malware – the hacked “Dropcam Total Home Immersion” account that […]

IPMI’s Inconvenient Truth: A Conversation With Dan Farmer

June 13, 2014 Paul Roberts

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 […]

For Smart TVs, Malware May Hide In Broadcast Content

June 12, 2014 Paul Roberts

Researchers at Columbia University have published research showing how new technology that combines broadband and broadcast content could enable a wide range of traditional and novel cyber attacks on smart televisions and other devices: forcing them to interact with malicious web pages, harvesting credentials or carrying out denial of service attacks. The paper, published in May, explores potential attacks on combined broadcast-broadband devices that use an industry specification called Hybrid Broadcast-Broadband Television (HbbTV). According to the researchers, Yossef Oren and Angelos D. Keromytis, the HbbTV specification combines broadband technologies like HTML and broadcast features in an insecure manner. The vulnerabilities affect a wide range of smart entertainment devices, including smart televisions, in Europe and the United States. “This enables a large-scale exploitation technique with a localized geographical footprint based on radio frequency (RF) injection, which requires a minimal budget and infrastructure and is remarkably difficult to detect,” the researchers write. “The technical complexity and […]
