Whack-A-Bash: New Vulnerabilities add to Patch Confusion

September 29, 2014 Paul Roberts

The good news about the rapid, industry response to the revelations about exploitable security holes in GNU Bash (Bourne Again Shell) (aka “Shellshock”) is that Linux users had a fix in hand almost as soon as they became aware of the problem those patches addressed. The bad news about the quick fixes for the two issues, CVE-2014-6271 and CVE-2014-7169, from the likes of Red Hat, Ubuntu, Debian and others is that – in being early- they fail to fix the problems we don’t yet know about. And that’s what we’re seeing in the wake of last week’s storm of patches: a steady drip-drip of disclosures that suggest that Bash may contain other problems worthy of new fixes. Within hours of the disclosure of the first holes, there were problems discovered by Red Hat Product Security researcher Todd Sabin, who found additional “off by one” errors in Bash that were assigned CVE-2014-7186 and CVE-2014-7187 and […]

Infographic: Possible Attacks on The Internet of Things

September 24, 2014 Paul Roberts

The folks over at Trend Micro have put together a nice infographic that reminds us that all those smart devices connected to the Internet communicate through some well worn channels, namely: standard communications protocols like Wi-Fi, Ethernet and Bluetooth that connect devices to each other and the global Internet, as well as HTTP that are used to transmit data to and from cloud based resources like management interfaces. Of course those standard protocols also leave IoT devices vulnerable to a wide range of commodity attacks: from brute force password cracking on web based management consoles to Man in the Middle attacks that can sniff out authentication credentials and hijack sessions. Trend’s infographic does a good job of depicting the various layers in the IoT stack and some of the likely attack vectors for each layer. It also gives advice on how to protect yourself (use encryption, patch software vulnerabilities, disable unused ports). Nothing ground breaking […]

FDA Seeks Collaboration on Medical Device Security

September 24, 2014 Paul Roberts

The U.S. Food and Drug Administration (FDA) on Tuesday put out a call for ideas and input on how best to secure medical devices and the healthcare system from cyber attack. In a federal notice, the FDA announced that it will hold an October workshop entitled “Collaborative Approaches for Medical Device and Healthcare Cybersecurity.” It also solicited input from stakeholders within the government and from the public health sector on medical device and healthcare cyber security. The workshop is scheduled for October 21 and 22 and will run from 9:00 AM to 5:00PM at the National Intellectual Property Rights Coordination Center Auditorium in Arlington, Virginia.

With Cars Connected to the Internet, What about Privacy? | Computerworld

September 19, 2014 Paul Roberts

Lucas Mearian has a long and quite thorough article over at Computerworld weighing the possible security and privacy risks posed by connected vehicles. Among other things, Mearian weighs the recent past and likely future of connected vehicles, noting that, “once mobile devices are connected to car infotainment systems and cars are connected to the Internet, vehicles will become a rich source of data for manufacturers, marketers, insurance providers and the government.” They’ll also be a target for hackers. The problem is that, unlike mobile phones, cars have useful lives that are measured in decades, not years – or even months. That makes it difficult for manufacturers, who want to make their vehicles state of the art, but also must deal with the reality of much longer development cycles and complex interactions between non-critical and critical on board systems. [Read more Security Ledger coverage of connected vehicles here.] A couple issues worth noting: […]

The Key to Security in the Internet of Things – IEEE Spectrum

September 19, 2014 Paul Roberts

IEEE Spectrum has an article that provides a nice overview of security and privacy issues on the Internet of Things. The article by Mark Anderson highlights a number of the issues that have cropped up on these pages as well, namely: the rush to market in the consumer IoT space (much of it driven by crowd funding sites like IndieGoGo and Kickstarter) the lack of a strong business case for (consumer) manufacturers to build security into IoT products the tendency of large manufacturers to pursue siloed security standards that thwart efforts to build devices interconnect with other IoT infrastructure (other devices, routers, etc.) So far efforts to coordinate IoT development around a single platform or set of standards have been reduced to predictable turf battles: Google’s Thread versus multi-vendor efforts like TheAllSeen Alliance, The Open Interconnect Consortium, The Industrial Internet Consortium versus Apple HomeKit and HealthKit and others. In the […]
