As you might know we are continuously doing research on medical devices. I presented some of the new results at Power of Community 2014 last week and we thought we would share some of the details with you here. The focus of the previous work was testing medical devices that are used in hospitals like patient monitors, syringe pumps or even MRIs. This time we looked at a device that every user can use at home and which is available to anyone on the market: A smart scale.
The scale implements some basic features as you might have guessed, that is measuring your weight. In this case there are a lot more additional features that you can use, e.g. measuring the air quality, the room temperature, your heart rate and your fat mass. The latter makes testing this device quite hard, because somebody has to step on it and the results were not funny at all and will be kept secret! 😉
I had the pleasure to participate in this year’s Power of Community and was invited to talk about the insecurity of medical devices. The conference is based in Seoul, Korea and started in 2006. It has a strong technical focus and it is a community driven event. For me it was great to participate as mostly hackers from Asia were there and I got the chance to talk to a lot of nice folks that I wouldn’t be able to meet otherwise. This is especially true for the host, vangelis.
We just got credits for a flaw we found in SAP Netweaver. The issue is a reflected Cross-Site Scripting (XSS). It can be triggered in the administrative interface for the Internet Communication Manager (ICM) and Web Dispatcher. This means that the targets for this XSS will definitely be users with administrative privileges. This makes it especially juicy for an attacker. Continue reading “XSS in SAP Netweaver”
One of our guiding principles at ERNW is “Make the World a Safer Place”. There could not be a topic that matches this principle more than the security or insecurity of medical devices. This is why we started a research project that is looking at how vulnerable those devices are that might be deployed in hospitals around the world. Recently the U.S. Food and Drug Administration (FDA) has put out a recommendation concerning the security of medical devices. It recommends that “manufacturers and health care facilities take steps to assure that appropriate safeguards are in place to reduce the risk of failure due to cyberattack, which could be initiated by the introduction of malware into the medical equipment or unauthorized access to configuration settings in medical devices and hospital networks”. We thought that we should take a look at how manufacturers deal with security for these devices. Continue reading “Medical Device Security”
Michael Thumann and me had the chance to give a talk at this year’s ISSE conference in Brussels, Belgium. ISSE was founded in 1999 as an initiative of the European Commission Directorate General Information Society. The con had a focus on eGovernment, electronic business processes and the corresponding security issues. Continue reading “ISSE 2013 – ERNW Rapid Rating System”
Some of us had the pleasure to participate in this year’s Daycon VII, three days of Real Hacking and Relevant Content, in Dayton, OH. The event began on September 16th with the Packetwars bootcamp. We had the chance to teach some really promising young students and to prepare them for the Packetwars battle that was scheduled four days later. The students had to go through topics like Windows security, network security and web application security both practical and in theory.
SUSE Linux Enterprise Server (SLES) has been around since 2000. As it is designed to be used in an enterprise environment the security of these systems must be kept at a high level. SLES implements a lot of basic security measures that are common in most Linux systems, but are these enough to protect your business? We think that with a little effort you can raise the security of your SLES installation a lot.
We have compiled the most relevant security settings in a SLES 11 hardening guide for you. The guide is supposed to provide a solid base of hardening measures. It includes configuration examples and all necessary commands for each measure. We have split the measures into three categories: Authentication, System Security and Network Security. These are the relevant parts to look for when hardening a system. The hardening guide also includes lists of default services that will help to decide which services to turn off, which is an essential step to minimize the attack surface of your system.
This is a short summary of some selected talks from the second day of this year’s Hack in the Box conference in Amsterdam.
Rethinking the Front Lines by Bob Lord
Bob Lord is currently the Director of Information Security at Twitter. He has worked at numerous companies in the area of security and software engineering.
In his keynote for the second day of HITB13AMS he tackled a topic that has raised a lot of discussions in the past months. His talk was a summary of what twitter does internally to ensure the security of the company and a plea to implement so called security awareness trainings for employees in a sustainable way.

Abusing Twitter’s API and OAuth Implementation by Nicolas Seriot
Nicolas Seriot (https://twitter.com/nst021) is an iOS Cocoa developer with an interest in privacy and security. He is currently a mobile applications developer and project manager in Switzerland. Nicolas focused his talk on the extraction of consumer tokens that are needed for OAuth to authenticate a consumer to a service provider. These tokens can then be used by rogue applications to gain access to a victims twitter account. Continue reading “Summary of Talks Held at HITB 2013 – Day 1”
