Ric Derbyshire on Living-Off-the-Plant OT Cyberattacks

Ric Derbyshire, a Principal Security Researcher at Orange Cyberdefense and an Honorary Researcher at Imperial College London, joins the Nexus Podcast to discuss how attackers are able to gain lateral movement across operational technology (OT) assets through a tactic known as Living Off the Plant.Similar to Living-off-the-Land attacks, Living-Off-the-Plant TTPs leverage native functionality specific to OT, with a potential negative impact on physical assets and safety concerns.

Deral Heiland on Weaponizing Cellular-Based IoT

Rapid7 Principal Security Research (IoT) lead Deral Heiland joins the Nexus Podcast to discuss work his team did on how attackers might weaponize cellular-based IoT. Rapid7 conducted three phases of this research, with the most recent digging into how attackers with access to these systems can abuse them to gain unauthorized access, potentially exfiltrate critical data, or pivot into backend network infrastructure.

Samir Boussarhane on New MITRE Caldera for OT Attack Simulators

Samir Boussarhane, senior cybersecurity engineer at MITRE, joins the Nexus Podcast to discuss some new simulator plug-ins added to Caldera for OT. Caldera for OT is an open-source adversary emulation platform that automates security assessments for operational technology (OT) systems. Samir provides context on a new simulator called the Aloha Water Treatment plant, which emulates a water utility and serves as a training platform for students, engineers, and IT security teams alike. Caldera for OT now also supports protocols such as BACnet, Modbus, and includes an HVAC simulator.Subscribe and listen to the Nexus Podcast here. Access the Aloha Water Treatment simulator.

Jim Labonty on Data Center, Manufacturing Cybersecurity

Former Pfizer head of global automation engineering Jim LaBonty joins the Nexus Podcast to discuss an article he wrote for Nexus on the need to secure data centers during kinetic conflict. He also explains the interlock between data centers and manufacturing facilities, and why a cyberattack against a data center can be devastating to the uptime and reliability of factory floors.

Tiffany Wilson on the Security Crisis of Consumer Tech in Healthcare

Tiffany Wilson, the founder of Wilson Inclusive Solutions (WINS), a disability accessibility consulting firm, joins the Nexus Podcast to discuss the proliferation of consumer technology into healthcare infrastructure. This technology—smart speakers that help manage medications or cameras that monitor vulnerable individuals—often handles patient data and safety, and operates in a regulatory void. Wilson advocates for frameworks that manufacturers and distributors can use to protect patient information and safety, given that most of this assistive technology functions as healthcare infrastructure without existing oversight and protection given healthcare technology.

Joe Slowik on Exposed, Internet-Facing OT

Joe Slowik, Director of Cybersecurity Alerting Strategy at Dataminr, joins the Nexus Podcast to discuss the alarming trend of lesser-skilled hacktivist groups leveraging operational technlogy (OT) and cyber-physical systems (CPS) in attacks. Many of these exposed devices are easily scannable and accessible online, and attackers are hurdling low barriers to entry such as poor or missing authentication, or insecure, legacy protocols to access assets and either cause disruption or move further into the process or business networks. Often these attacks are carried out without exploits or malware. Subscribe and listen to the Nexus Podcast here. Download Team82's report: "Analyzing CPS Attack Trends"

Phil Englert on Medical Device Cybersecurity

Phil Englert, VP, Medical Device Security, Health-ISAC joins to discuss the cybersecurity risks introduced by legacy technology in healthcare and how it impacts patient care and safety. Phil also brings some context and insight into the U.S. Food and Drug Administration's (FDA) updated guidance on cybersecurity requirements for medical devices aimed at manufacturers and premarket product submissions. The guidance proposes stricter secure development processes, software component tracking, and more.Subscribe and listen to the Nexus Podcast here.
