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 […]

Car Makers, Suppliers Going Their Own Way On Security

June 1, 2014 Paul Roberts

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.

Podcast: Is Defense-In-Depth The Only Real Heartbleed Fix?

May 30, 2014 Paul Roberts

Like everyone else, we wrote extensively in the last month about the serious security vulnerability in OpenSSL dubbed “Heartbleed,” which affected many of the world’s leading web sites and services, including Facebook and Google. The large-type headlines about Heartbleed have passed. But that doesn’t mean that the danger has. As we have noted, we are entering a phase that might be considered Heartbleed’s ‘long tail.’ Most of the well-trafficked websites that were vulnerable to Heartbleed have gotten around to fixing the vulnerability. But public-facing web servers are only the beginning of the story for OpenSSL. Chasing down the vulnerability’s long tail in third-party applications and on internal web sites and applications is a much larger task. As I’ve noted: open source components make their way into all manner of applications and bespoke products these days, often without any effort to assess the security of the borrowed code. For companies that need to protect critical IT […]

Video: The Internet of Things and Enterprise Risk

May 29, 2014 Paul Roberts

The Security Ledger recently hosted our inaugural event: The Security of Things Forum (SECOT). This was a high-energy, day long conference in Cambridge, Massachusetts, that brought together subject experts, executives and thought leaders from disparate areas like high tech, finance and industrial systems to talk about the tsunami of change that is the Internet of Things. One of the big questions hovering over the event: how will IoT technologies and services change the security paradigm that we’ve all be operating under- but especially in enterprises. In fact, IoT and enterprise was the topic of our very first discussion of the day: a panel chaired by Chris Rezendes of INEX Advisors, a leading consultancy focusing on IoT. SECoT Forum 2014 – Democratized Data, IOT and Enterprise Risk from Exhibitor Media Group on Vimeo It’s a really big and messy problem. As panelist Ken Pfeil of Pioneer Investments pointed out: the hack of […]
