SummerCon 2018 In Review

SummerCon is a different type of conference than most, and honestly sometimes it’s tough to hear the talks over the noise of the crowd at the bar. This year, the organizers added a second venue to try to spread out the noise from the great conversations and impromptu meetings, so some of the talks could be heard. We wanted to share a few notes on our teams’ key takeaways from the weekend.

Sharing the Team’s Recent Research at DefCon & BlackHat

At River Loop Security, we are always looking to advance the state of cybersecurity research alongside our work tackling our clients’ toughest problems. Presenting our research at computer security conferences is one way that we hope to share our lessons learned with the community. This summer, we’re excited to present at BlackHat USA and DefCon. We’ll be showcasing some select areas of our team’s research: 1) RF Fuzzing and Hardware Tools, 2) Reversing a Windows Antivirus Emulator, 3) Understanding Attack Attribution.

ZigBee & Z-Wave Security Brief: Part 2

This is the second of two blog posts where we will share a summary of the differences. We encourage you to read the first post for background on the purpose of this post and discussion of security levels and keying techniques. The ZigBee and ZWave protocols have both undergone numerous revisions and support many different security modes and edge cases. In this discussion, we will try to focus on core design decisions and features, and leave out discussion or investigation of edge cases for brevity.

ZigBee & Z-Wave Security Brief

We have performed in-depth evaluations of many products built on ZigBee and Z-Wave for clients, and we are often helping clients understand vulnerabilities in IoT products built on standard protocols such as these. We believe that it will benefit the overall community to share a brief summary of our comparisons between these two popular protocols based on the recent ZigBee 3.0 and Z-Wave S2 specifications which both aimed in-part to update the protocols to an increased level of security.

KillerBee Support for Sewino Open-Sniffer Platform

As part of our continued commitment to supporting open-source tools, we have added support to KillerBee for the Sewino Open-Sniffer 802.15.4 capture interface. This is the first supported device capable of 900 MHz sniffing. The KillerBee code is available to use it, although we are not actively maintaining and testing this integration. We welcome improvements to the integration or collaborations to expand the supported interfaces further. You can also read about the integration on their site.

ApiMote v4beta Released: A IEEE 802.15.4 Sniffing/Injection Interface

We have announced the ApiMote v4beta design and released it as open-source hardware at the TROOPERS14 security conference. This hardware was designed specifically with security researchers and assessors in mind, and is supported by the KillerBee software toolkit and GoodFET. We believe it offers unique capabilities unfulfilled by other interfaces currently available. If you want to use this board, you can build it based on the open-source design files or obtain a pre-built, tested, and programmed one from us.

IEEE 802.15.4/ZigBee Wireless IDS Beta Released

We have released BeeKeeper Wireless Intrusion Detection System (WIDS), an open-source IEEE 802.15.4 Wireless IDS at the TROOPERS14 security conference. This beta version demonstrates a strong framework for multiple sensors and a centralized analytic engine. A few simple detection scripts are included to demonstrate detecting common attacks. You can read about it on our projects page or review our presentation. The source code is available and we encourage anyone interested to submit updates to it.
