Hawaii International Conference on System Sciences/IEEE Computer Society: Api-do: Tools for Exploring the Wireless Attack Surface in Smart Meters

Security is critical for the wireless interface offered by soon-to-be-ubiquitous smart meters; if not secure, this technology provides an remotely accessible attack surface distributed throughout many homes and businesses. History shows, however, that new network interfaces remained brittle and vulnerable (although believed otherwise) until security researchers could thoroughly explore their attack surface.

DEF CON 26

River Loop had the privilege of presenting our latest efforts in wireless fuzzing, including the TumbleRF software framework and the Orthrus offensive radio interface, at DEF CON 26 in Las Vegas, NV. This research highlights the importance of securing oft-overlooked system components, such as non-IP network interfaces and hardware buses. 2014’s Isotope 802.15.4 bugs highlighted an interesting class of vulnerability existing at the PHY layer, so we wrote some tools to make uncovering bugs like those more systematic.

Black Hat 2018

River Loop was thrilled to present its TumbleRF fuzzing framework at Black Hat Arsenal, a forum dedicated to open source security research and software at Black Hat USA. TumbleRF is an open source Python framework that enables researchers to fuzz arbitrary RF technologies down to the PHY. As River Loop’s 2014 Isotope research demonstrated, PHY-layer bugs can have serious implications, and often hide in plain sight. Thus, developing a tool to make finding these bugs systematic seemed like a good fit.

Troopers 14: Making (and Breaking) an IEEE 802.15.4 WIDS

Presented the ApiMote v4beta hardware for sniffing and injection on IEEE 802.15.4 networks and released as open source. Demonstrated the beta BeeKeeper WIDS framework for wireless intrusion detection on 802.15.4. Showed a technique for injecting packets which are seen at the PHY layer by some radio-chips but not by other chips, even when both chips are IEEE 802.15.4 compliant. You can download a copy of the presentation here.

DefCon 20

Presented our project to create the ApiMote hardware at the Wireless Village. The ApiMote platform is designed specifically to fulfill the needs of security assessors, based on experience from both lab-research and field assessments. It is inexpensive, easy to program, supports expansion and battery power, uses an internal or external antenna, and has low-level support for cutting-edge RF research (low-level registers exposed, in support of PIP, POOP, etc).

ToorCon Seattle '11: Tools for Practical Exploration of the 802.15.4 Attack Surface

Presented toolkit for interacting with IEEE 802.15.4/Zigbee. Our tools build on top of the KillerBee framework developed by Josh Wright, and add support for additional hardware, code stability, as well as additional functionality such as reflexive jamming. In addition to a brief introduction to the issues of 802.15.4 security, demonstrated attendees how to get involved in attacking the surface themselves – the hardware and software they need – and showed how this enables them to not only perform their own assessments, but how it can provide attackers a way to interfere with the operation of networks as well.

ShmooCon '11: ZigBee Security: Find, Fix, Finish

Techniques for sniffing ZigBee packets have been presented, as have theoretical vulnerabilities in other types of wireless sensor networks, but this talk uses injection and intelligent packet generation to move towards real proof-of-concept attacks on 802.15.4/ZigBee networks.

We analyze which proposed wireless sensor network attacks actually work on ZigBee, and provide proof of concept implementations of theoretical attacks.
