Ralph Langner is one of the foremost experts on the security of critical infrastructure that we have. So, generally, when Ralph says something – whether its about Stuxnet, or cyberwar or the security of nuclear power plants – folks listen. And these days, Ralph is wondering, out loud, whether our reliance on digital systems to manage critical infrastructure has gone too far. The answer, he suggests, may be to go “back to the future,” as it were: reintroducing analog systems into the control process chain as a backstop for cyber attacks. Case in point: the Department of Homeland Security’s ICS-CERT warned on Friday that firmware for Siemens SIMATIC S7-1500 CPUs (Central Processing Units) contain nine vulnerabilities that could enable attacks such as cross site request forgery, cross site scripting and URL redirection. (Siemens has issued a firmware update that patches the holes.) Langner is among the world’s foremost experts on […]

Is Refrigerator Spam Really In Our Future?
I came across an interesting post over on Wearable World News today titled “The Danger of Smart Spam In the Internet of Things.” The article, by Jessica Groopman, ran yesterday and provides a kind of conceptual overview of the security and IoT space. I think Goodman gets it mostly right: she talks about the proliferation of device types and platforms that will (or already does) characterize the Internet of Things. With hundreds of billions (compared with hundreds of millions) of Internet connected endpoints, cyber criminals, hacktivists and other bad actors have an even greater ability to create armies of compromised endpoints and harness their collective power in attacks. Goodman also gets it right when she notes that many “smart” devices run commodity operating systems like Linux and don’t require lots of special effort to reverse engineer. Finally, IoT devices frequently are low power and embedded systems that lack the processing […]
SOHOwned: 300K Home Routers Hacked
A string of reports in recent weeks has focused a spotlight on rising attacks against an often-overlooked piece of equipment that can be found in almost every home and business: the wireless router. Just this week, the security firm Team Cymru published a report (PDF) describing what it claims is a widespread compromise of small office and home office (SOHO) wireless routers that was linked to cyber criminal campaigns targeting online banking customers. Cymru claims to have identified over 300,000 SOHO devices (mostly in Asia and Europe) that were compromised. According to the report, the compromises first came to light in January, after Team Cymru analysts noticed a pattern of SOHO routers with overwritten DNS settings in central Europe. The affected devices are from a range of manufacturers, including well-known brands like D-Link, Micronet, Tenda and TP-Link. The devices were vulnerable to a number of attacks, including authentication bypass and cross-site […]
Vulnerabilities Lurking Far And Wide In IoT Ecosystem
The Internet of Things (IoT) promises to revolutionize the way people live and work. But while the media’s attention is focused on high-profile Internet of Things firms like NEST, the smart-home products vendor that Google acquired for more than $3 billion last month, much of the innovation in IoT – at least in the consumer market – is a bottom-up, grass roots phenomenon. Quietly, the combination of ready-made components, point and click development environments and cloud based back end management tools has enabled an army of (mostly) novice developers to assemble novel, connected products for a public enraptured with the idea of using their mobile devices to control something — anything. At the same time, crowd-funding platforms like Kickstarter and Indiegogo have created a platform for products to get funded and distributed to hundreds, thousands or even tens of thousands of customers – once a monumental task. That’s great for the […]
Security and The Internet of Things: An RSA Roadmap
The RSA Security Conference starts next week in San Francisco: the central event of a week-long orgy of IT security wheeling and dealing in the Bay Area. Though its roots are as a small and clubby gathering of cryptographers, RSA long ago stopped being that, and started resembling a kind of speed dating event for technology and IT security firms. Sure – there are plenty of interesting talks at RSA, but the important work takes place in private suites of adjoining hotels and chance encounters in the halls of the Moscone. If there’s a big IT security deal in the offing – like IBM’s $1 billion acquisition of Trusteer, or FireEye’s purchase of the firm Mandiant – chances are good that the conversation started at RSA. Long and short: RSA is a snapshot of the security industry at a particular place and time. As such, it tends to be a […]
