[DefCon32] Changing Global Threat Landscape
Rob Joyce, a distinguished former National Security Agency (NSA) official, joined Jeff Moss, known as The Dark Tangent and founder of DEF CON, for a riveting fireside chat at DEF CON 32. Their discussion delved into the dynamic evolution of global cyber threats, with a particular focus on the transformative role of artificial intelligence (AI) in reshaping cybersecurity. Rob, recently retired after 34 years at the NSA, brought a wealth of experience from roles such as Cybersecurity Coordinator at the White House and head of the NSA’s Tailored Access Operations. Jeff facilitated a conversation that explored how AI is redefining defense strategies and the broader implications for global security, offering insights into the challenges and opportunities ahead.
The Evolution of Cyber Threats
Rob began by reflecting on his extensive career at the NSA, where he witnessed the transformation of cyber threats from isolated incidents to sophisticated, state-sponsored campaigns. He highlighted how adversaries now leverage AI to enhance attack vectors, such as spear-phishing and polymorphic malware, which adapt dynamically to evade detection. Rob emphasized that the scale and speed of these threats demand a shift from reactive to proactive defenses, underscoring the importance of understanding adversaries’ intentions through signals intelligence. His experience during the Iraq War as an issue manager provided a unique perspective on the strategic use of cyber intelligence to counter evolving threats.
AI’s Dual Role in Cybersecurity
The conversation pivoted to AI’s dual nature as both a tool for attackers and defenders. Rob explained how AI enables rapid analysis of vast datasets, allowing defenders to identify patterns and anomalies that would be impossible for human analysts alone. However, he cautioned that adversaries exploit similar capabilities to craft advanced persistent threats (APTs) and automate large-scale attacks. Jeff probed the balance between automation and human oversight, to which Rob responded that AI-driven tools, like those developed by the NSA, are critical for scaling defenses, particularly for protecting critical infrastructure. The integration of AI, he noted, is essential to keep pace with the growing complexity of cyber threats.
Strengthening Defenses Through Collaboration
Rob stressed the importance of bipartisan support for cybersecurity, noting that stopping foreign adversaries is a shared goal across administrations. He highlighted the role of the Office of the National Cyber Director (ONCD) in convening agencies to synchronize efforts, citing examples where ground-up collaboration among agencies has led to effective threat mitigation. Jeff asked about the resource gap, and Rob acknowledged that the scope of threats often outpaces available resources. He advocated for widespread adoption of two-factor authentication and secure software development practices, such as moving away from memory-unsafe languages, to build more defensible systems.
Building a Resilient Future
Concluding, Rob expressed optimism about the trajectory of cybersecurity, emphasizing that automation can alleviate the burden on security teams, particularly for 24/7 operations. He underscored the need for robust teams and innovative technologies to address the relentless pace of vulnerabilities exploited by attackers. Jeff echoed this sentiment, encouraging the DEF CON community to contribute to shaping a secure digital landscape. Their dialogue highlighted the critical role of collaboration between government, industry, and the hacker community in navigating the ever-changing threat landscape.

[DefCon32] Abusing Legacy Railroad Signaling Systems
David Meléndez and Gabriela Gabs Garcia, researchers focused on transportation security, expose critical vulnerabilities in Spain’s legacy railroad signaling systems. Their presentation reveals how accessible hardware tools can compromise these systems, posing risks to train operations. By combining theoretical analysis with practical demonstrations, David and Gabriela urge stakeholders to bolster protections for critical infrastructure.
Vulnerabilities in Railroad Signaling
David and Gabriela begin by outlining the mechanics of railway signaling, which relies on beacons to communicate track status to train operators. Using off-the-shelf tools, they demonstrate how these systems can be manipulated to display false signals, potentially causing derailments or collisions. Their research, motivated by Spain’s high terrorist alert level, highlights the ease of tampering with outdated infrastructure, drawing parallels to past incidents like the 2004 Madrid train bombings.
Exploiting Accessible Technology
The duo details their methodology, showing how domestic hardware can override signal frequencies to mislead train operators. By crafting a device that mimics legitimate signals, attackers could disrupt train circulation without detection. David emphasizes the simplicity of these attacks, underscoring the urgent need for modernized systems to counter such threats, especially given the public availability of required tools.
Risks to Critical Infrastructure
Gabriela addresses the broader implications, noting that Spain’s railway vulnerabilities reflect global risks. The 2004 Madrid bombings, which killed 193 people, serve as a stark reminder of the stakes. Their findings reveal that motivated actors with basic knowledge could exploit these weaknesses, endangering lives and infrastructure. The researchers call for increased investment in security to prevent catastrophic incidents.
Call for Industry Action
Concluding, David and Gabriela advocate for a reevaluation of railway security protocols. They urge stakeholders to implement robust countermeasures, such as encrypted signaling and real-time monitoring, to protect against tampering. Their work aims to spark industry-wide dialogue, encouraging collaborative efforts to safeguard transportation networks worldwide.

[DefCon32] On Your Ocean’s 11 Team, I’m the AI Guy (Technically Girl)
Blending the allure of high-stakes gambles with cutting-edge threats, Harriet Farlow, an AI security specialist, navigates the intersection of adversarial machine learning and casino operations. Targeting Canberra Casino, she exposes frailties in emerging AI integrations for surveillance and monitoring. Her exploits disrupt facial recognition, evade detection, and manipulate gameplay, illustrating broader perils in sectors reliant on such systems.
Harriet’s background spans physics, data science, and government intelligence, culminating in founding ML Security Labs. Her focus: deceiving AI to reveal weaknesses, akin to cyber intrusions but tailored to models’ statistical natures.
Casinos, epitomizing surveillance-heavy environments, increasingly adopt AI for identifying threats and optimizing play. Canberra, though modest, mirrors global trends where a few providers dominate, ripe for widespread impacts.
Adversarial attacks perturb inputs subtly, fooling models without human notice. Harriet employs techniques like fast gradient sign methods, crafting perturbations that reduce classification confidence.
Targeting Facial Recognition
Facial systems, crucial for barring excluded patrons, succumb to perturbations. Harriet generates adversarial examples via libraries like Foolbox, adding noise that misclassifies faces.
Tests show 40.4% success in evading matches, but practical adaptations ensure consistent bypasses. This equates to denial-of-service equivalents in AI, disrupting reliability.
Broader implications span medical diagnostics to autonomous navigation, where minor alterations yield catastrophic errors.
Evading Surveillance and Gameplay Monitoring
Surveillance AI detects anomalies; Harriet’s perturbations obscure actions, mimicking wild exploits.
Gameplay AI monitors for advantages; adversarial inputs confuse chip recognition or behavior analysis, enabling undetected strategies.
Interviews with casino personnel reveal heavy reliance on human oversight, despite AI promises. Only 8% of surveyed organizations secure AI effectively, versus 94% using it.
Lessons from the Inflection Point
Casinos transition to AI amid regulatory voids, amplifying risks. Harriet advocates integrating cyber lessons: robust testing beyond accuracy, incorporating security metrics.
Her findings stress governance: people and processes remain vital, yet overlooked. As societies embrace AI surveillance, vulnerabilities threaten equity and safety.
Harriet’s work urges cross-disciplinary approaches, blending cyber expertise with AI defenses to mitigate emerging dangers.
