Andy Greenberg over at Wired has an interesting piece of news coming out of last week’s Derbycon hacker conference in Louisville, Kentucky. According to Greenberg and Wired, researchers Adam Caudill and Brandon Wilson showed off their own version of Karsten Nohl and Jakob Lell’s BadUSB malware, and that they’d released the code on Github. Their presentation raises the stakes for USB manufacturers to fix the BadUSB problem or leave hundreds of millions of users vulnerable, Greenberg writes. At a presentation at the Black Hat Briefings in August, Nohl and Lell, both of Security Research Labs (SRLabs), showed how the controller chips inside common USB devices can be reprogrammed, allowing USB peripherals to impersonate other kinds of devices. Among other things, Nohl demonstrated how a BadUSB infected device could emulate a USB keyboard, issuing commands to a connected machine using the permissions of the logged-in user. Alternatively, an infected USB could spoof a […]

FDA Issues Guidance on Security of Medical Devices
The U.S. Food and Drug Administration (FDA) issued final guidance on Wednesday that are designed to strengthen the safety of medical devices. The FDA called on medical device manufacturers to consider cyber security risks as part of the design and development of devices. The document, “Content of Premarket Submissions for Management of Cybersecurity in Medical Devices,” asks device makers to submit documentation to the FDA about any “risks identified and controls in place to mitigate those risks” in medical devices. The guidance also recommends that manufacturers submit documentation of plans for patching and updating the operating systems and medical software that devices run. The document, which will be released on Thursday, does not contain specific requirements. Rather, it describes the kinds of things that medical device manufacturers should consider when preparing pre-market submissions for medical devices in areas such as information confidentiality, integrity, and availability, the FDA said. The release of the document follows the […]
Whack-A-Bash: New Vulnerabilities add to Patch Confusion
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
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
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. [Read more Security Ledger coverage of connected medical devices here.] The Department of Health and Human Services (HHS) is looking for ideas about how best to implement aspects of both Executive Order 13636 for“Improving Critical Infrastructure” and follow-on guidance like the National Institute of Standards and Technology’s (NIST’s) “Framework for Improving […]
