THaW researcher Kevin Fu’s work on acoustic device hacking has recently been featured in the New York Times. The article discusses the team’s work on using acoustic signals to fool sensors in mobile device, and create the potential for security violations.

WALNUT: Waging Doubt on the Integrity of MEMS Accelerometers with Acoustic Injection Attacks
THaW researchers Haiming Jin and Klara Nahrstedt of UIUIC, in collaboration with Lu Su of SUNY Buffalo, recently had a paper accepted to IEEE INFOCOM 2017. Entitled CENTURION, the research explores the incentivization of participants in crowd sourced data collection. Notably, CENTURION rethinks the existing model of crowd sourced data collection (one consumer, one set of incentives), and instead takes the novel approach of applying a double auction model with multiple consumers and multiple incentives. The result is a system that can guarantee non-negative social welfare impact, among other benefits. To explore CENTURION further, click below.
In mid-November THaW was excited to co-host, along with the Center For Digital Strategies at the Tuck School of Business and the Owen School of Management, a workshop on building secure connected healthcare organizations.
The workshop was attended by CISOs from twelve interested healthcare organizations, as well as members of the THaW project. It provided for a day of conversation about cybersecurity best practices and challenges. Over the course of the workshop, with moderation by Eric Johnson and Hans Brechbuhl, the group touched upon a wide array of subjects; we are now happy to present some key insights and a summary of the day’s proceedings. Highlights include insights regarding phishing attacks, medical device security, and the emerging Internet of things.

Overview: Building Secure Connected Healthcare Organizations
THaW contributor Eric Johnson recently sat down with VP and CISO of Hospital Corporation of America Paul Connelly to discuss advancements in healthcare analytics and information security. Over the course of the discussion the two touch on the sheer volume of data created by HCA, and how analytics can be used to give that data value in contributing to informed decision making, while at the same time protecting patient security.

A few months ago we announced the results of our Wanda project, as published in INFOCOM 2016. Today we’re excited to share this new video description of the project! Thanks to Abby Starr and Shiyao Peng of Dartmouth’s DALI lab, and Tim Pierson of the THaW team, for this fun and informative production.
Nearly every setting is increasingly populated with wireless and mobile devices – whether appliances in a home, medical devices in a health clinic, sensors in an industrial setting, or devices in an office or school. There are three fundamental operations when bringing a new device into any of these settings: (1) to configure the device to join the wireless local-area network, (2) to partner the device with other nearby devices so they can work together, and (3) to configure the device so it connects to the relevant individual or organizational account in the cloud. The challenge is to accomplish all three goals simply, securely, and consistent with user intent. We call our approach Wanda – a `magic wand’ that accomplishes all three of the above goals – and evaluate a prototype implementation.
THaW researchers A.J. Burns, Eric Johnson and Peter Honeyman, have compiled a compelling chronology of medical device security in their recently published article in Communications of the ACM, “A Brief Chronology of Medical Device Security” (see the THaW blog’s publication page for complete reference information and a link to the article).
The authors identify three key points relating to medical devices:
- Frightening language and misinformation often characterize discussions of cybersecurity and medical devices.
- There are always security trade-offs when designing, deploying, and maintaining medical devices.
- Medical devices are often not that different than other network-enabled digital devices, in terms of their vulnerability to network-based cyberattack.
The authors further identify four major periods that span the evolution of medical devices:
- Complex systems and accidental disasters
- Implantable medical devices
- The threat of unauthorized access
- Cyber threats to medical device security
The article offers a comprehensive examination of the legislative timeline and the evolving threats to information security in healthcare. They argue that “the steps we take today will largely define the future of medical device security,” and while there is a temptation to publicly wring our hands in despair over medical-device insecurity, “we must resist the temptation to sensationalize the issues…and instead apply sober, rational, systematic approaches to understanding and mitigating security risks.”
The authors conclude by challenging the medical-device community to better secure these devices:
“…it is safe to say that patients’ reluctance to accept medically indicated devices due to concerns about security poses a greater threat to their health than any threat stemming from medical device security…it is incumbent on our field to continue to prioritize the security of medical devices as a part of our fiduciary responsibility to act in the interests of those who rely on these life-saving devices.”

“For decades, there’s been an unofficial truce between cybersecurity researchers and companies: When good guy hackers find a problem, they give companies a chance to fix it before going public.
But a cybersecurity firm called MedSec just upended that truce.”
“While medical device manufacturers must improve the security of their products, claiming the sky is falling is counterproductive.” – ThaW researcher, Kevin Fu
MedSec, a medical security firm, has formed an unusual partnership with investment firm Muddy Waters to generate revenue based on MedSec infosec research. When MedSec recently found alleged faults in St. Jude’s implantable heart equipment, it alerted Muddy Waters rather than St. Jude’s as tradition normally dictates. Muddy Waters promptly issued a research report highlighting the alleged faults and shorted St. Jude’s stock, giving MedSec a portion of the proceeds from the short sale.
However, ThaW researcher, Kevin Fu, and University of Michigan colleagues attempted to replicate the MedSec research and determined that MedSec’s findings were “inconclusive”. For more information on the Michigan investigtion see –
This saga is far from complete, as Fu’s team continues to look into the MedSec findings.

While mHealth has the potential to increase healthcare quality, expand access to services, reduce costs, and improve personal wellness and public health, such benefits may not be fully realized unless greater privacy and security measures are implemented, according to a new paper published in the June issue of Computer.
Professors David Kotz (Dartmouth), Carl A. Gunter (University of Illinois), Santosh Kumar (University of Memphis), and Jonathan P. Weiner (Johns Hopkins), in their paper (Privacy and Security in Mobile Health: A Research Agenda) challenge the research community to tackle several critical challenges related to security and privacy in mHealth: data sharing and consent management; access control and authentication; confidentiality and anonymity; mHealth smartphone apps; policies and compliance; accuracy and data provenance; and security technology.
With 45 percent of Americans facing chronic disease, which accounts for 75 percent of the annual $2.6+ trillion spent on healthcare, and many developed countries facing aging populations, mobile technology can serve as a great resource to help address these problems – provided mHealth companies and other stakeholders are able to meet the privacy and security challenges associated with these technologies.
For additional information contact Professor David Kotz, the Champion International Professor in the Department of Computer Science at Dartmouth College.

With recent, well-publicized ransomware attacks on major medical institutions, THaW researchers have been tasked with explaining this uptick in nefarious activity. Within the last fortnight, both Kevin Fu and Avi Rubin have been interviewed concerning securing medical IT systems and ransomware specifically. Here are links to their interviews: Fu (MIT Technology Review) and Rubin (C-SPAN Washington Journal).
