Martin Doyhenard, a seasoned security researcher, captivated the DEF CON 32 audience with his exploration of innovative web cache exploitation techniques. Focusing on exploiting ambiguities in RFC standards, Martin unveiled two novel methods—Static Path Deception and Cache Key Confusion—that push the boundaries of web cache attacks. Through detailed case studies and a live demonstration, he showcased how these techniques can compromise application confidentiality, enable arbitrary cache poisoning, and even achieve full site takeovers, providing actionable insights for security practitioners to identify and mitigate such vulnerabilities.

Unveiling Web Cache Mechanics

Martin began by elucidating the inner workings of web caches, which store frequently accessed content to enhance website performance. He highlighted how caches rely on URL parsing to determine what to store and serve, yet inconsistencies in parsing across platforms create exploitable vulnerabilities. By leveraging ambiguities in RFC standards, attackers can manipulate cache behavior to serve malicious content or expose sensitive data. Martin’s clear explanation set the stage for understanding the sophisticated attacks that followed, emphasizing the critical role of URL parsers in web security.

Static Path Deception: Breaching Confidentiality

Delving into his first technique, Martin introduced Static Path Deception, a method that exploits cache handling of static file paths to compromise application confidentiality. Using a case study involving Nginx behind Cloudflare, he demonstrated how attackers can trick caches into serving sensitive content to unauthorized users. By crafting specific URL patterns, Martin showed how this technique bypasses traditional cache restrictions, exposing private data. His findings underscore the need for consistent cache configuration across content delivery networks and web servers to prevent such breaches.

Cache Key Confusion: Poisoning and Denial of Service

Martin then presented Cache Key Confusion, a technique exploiting discrepancies in how platforms like Microsoft Azure Cloud normalize cache keys. He illustrated how attackers can manipulate URL parsing to poison caches, serving malicious content to all users or triggering denial-of-service attacks. His live demo combined Cache Key Confusion with an open redirect vulnerability to execute arbitrary JavaScript, achieving a complete site takeover. This powerful demonstration highlighted the far-reaching impact of parser inconsistencies and the potential for significant disruption in cloud-based environments.

Mitigation and Community Engagement

Concluding, Martin shared practical strategies to counter these vulnerabilities, urging organizations to audit cache configurations and disable key normalization where possible. He introduced his open-source tool, Cache Killer, designed to detect parsing discrepancies, and encouraged the DEF CON community to contribute to its development. By sharing references to prior research and his own findings, Martin fostered a collaborative approach to improving web cache security, inspiring attendees to hunt for similar vulnerabilities in bug bounty programs and beyond.

Amid the arduous arena of application assurance, where integration inspections intersect infrastructure intricacies, Daniel Ward, a .NET navigator and testing tactician, torpedoes the tired trope of SQLite as EF Core’s ersatz examiner. With a penchant for precision and a portfolio of pragmatic patterns, Daniel decries the discrepancies—dialect drifts, devious defaults—that delude developers into dubious dependability. His herald: TestContainers, a titan of transient testing, tethering true-to-type databases to dotnet diagnostics, ensuring examinations echo environments exactly.

Daniel dives direct: SQLite’s siren song—simplicity’s shadow—seduces with speed yet sabotages similitude, spawning spurious successes in schema shadows. Real realms revel in PostgreSQL or SQL Server; sans such sentinels, tests tantalize with triumphs that tumble in truth. His thesis: TestContainers triumphs, turbocharging temporaries—containers conjured cleanly, configured crisply—for credible, containerized corroboration.

Ditching the Decoy: Drawbacks of Database Doppelgangers

SQLite’s shortcomings spotlight starkly: syntax schisms—TOP versus LIMIT—thwart translations; transaction treatments transmute, transactions toggling differently. Daniel details dev database dilemmas: devious dependencies, drift-prone data, deployment drudgery. False flags flourish: tests triumph trivially, only to falter in flight, fostering fragile faith.

His horror stories: SQLite’s solitary schema swallows specifics, sans stored procedures or sequences; in-memory imposters ignore indexes, inflating illusions. Daniel’s decree: discard decoys for doppelgangers divine—TestContainers delivers, Docker-driven duplicates that duplicate dynamics deftly.

Containers as Champions: TestContainers’ Triumphs

TestContainers, Daniel declaims, democratizes diligence: NuGet-nimble, it nurtures nodes—Postgres pods, SQL Server ships—spinning sans setup strife. Benefits burgeon: bit-for-bit fidelity, flakeless flurries, fleet-footed forays. Reusability reigns: withReuse() recycles realms, reining runtime rigorously.

Daniel demos deftly: dotnet add package Testcontainers.PostgreSql; a builder begets a beast, beckoning a bespoke bastion. Connection strings cascade, EF contexts calibrate, tests transact transparently—Respawn resets, restoring rectitude routinely.

Precision in Practice: Pitfalls and Panaceas

Pitfalls persist: parallelism’s pandemonium, port pandemonium—Daniel dispels with Docker Desktop’s discipline, orchestration’s oversight. His heuristic: harness health checks, heed horizons—hundreds hum harmoniously, hovering at half-minutes for hordes.

Respawn’s renaissance: rollback routines, resetting relations rigorously, rectifying residue. Daniel’s distillation: TestContainers transmutes testing from torment to triumph, true tests tempering temper tantrums.

At KotlinConf2024, Daniel Terhorst-North shared a heartfelt reflection on the traits of exceptional programmers, drawing from his 30-year career and a colleague who embodies these qualities. Without a formal degree, this programmer excels by starting tasks, prioritizing outcomes, simplifying solutions, choosing tools wisely, and fostering team growth. Daniel’s narrative, blending personal anecdotes and practical advice, inspires developers to cultivate curiosity, resilience, and empathy while building impactful software.

Starting with Action

Great programmers dive into tasks without hesitation. Daniel recounted how his colleague tackles projects by starting anywhere, embracing the unknown. This “just start” mindset counters procrastination, which Daniel admits to masking as research. By iterating rapidly—trying, failing, and learning—programmers overcome perfectionism and ego. Daniel likened progress to navigating a grid city, moving stoplight to stoplight, accepting delays as part of the journey, ensuring steady advancement toward solutions.

Prioritizing Outcomes Over Code

Building products, not just code, defines effective programming. Daniel emphasized that emotional investment should focus on outcomes, not code, which is merely a means. The best programmers write minimal, high-quality code, holding no attachment to it. Studying the domain reveals user needs, as Daniel learned during a financial project where ignorance of CDOs led to unintended consequences. Observing users’ frustrations, like manual data entry, uncovers opportunities to eliminate friction, enhancing product value.

Simplifying the Complex

Exceptional programmers see through complexity to find simple solutions. Daniel shared a story of his colleague bypassing bloated Java web servers by writing a lean one from the HTTP spec. In another case, a team debating JSON libraries was guided to implement a simple interface for nine serialized objects, avoiding heavy dependencies. Writing clear documentation, like a streamlined README, drives “embarrassment-driven refactoring,” ensuring solutions remain concise and maintainable, solving only what’s necessary.

Choosing Tools for the Problem

Tool selection should prioritize the product, not team familiarity. Daniel recounted a team learning Scala to sketch code quickly, despite no prior experience, proving adaptability trumps comfort. He advocated for polyglot programming, using Advent of Code to learn Rust and Go, which broadened his problem-solving perspective. By minimizing cognitive distance between problem and solution, as Rich Hickey’s “Simple Made Easy” suggests, programmers select tools that evolve with project needs, ensuring flexibility.

Fostering Team Care

Great programmers uplift their teams. Daniel finds joy in pairing and teaching, inspired by an XKCD comic about the “lucky 10,000” who learn something new daily. He creates environments for learning, drawing from jiu-jitsu’s teaching-first philosophy. Sending teams home to rest, as Daniel advocates, boosts effectiveness, while assuming positive intent—per Virginia Satir’s family therapy principle—builds empathy, transforming conflicts into opportunities for collaboration and growth.

Building Psychological Safety

Psychological safety, per Amy Edmondson’s research, is vital for high-performing teams. Daniel explained that safe teams encourage saying “I don’t know,” seeking help, and disagreeing without fear. A study of surgical teams showed high performers report more errors, reflecting trust, not incompetence. In software, this translates to teams where questions spark learning, help fosters collaboration, and dissent drives improvement, creating dynamic, challenging environments that fuel innovation.

Growing as a Programmer

Personal growth sustains programming excellence. Daniel urged developers to stay current through communities, contribute actively, and remain skeptical of trends like AI hype. Practicing via challenges like Advent of Code sharpens skills, as Daniel found when switching languages mid-puzzle. Balancing work with physical activities, like running, and prioritizing rest prevents burnout. By embracing continual learning and kindness, programmers evolve, as Daniel’s colleague demonstrates, into impactful, resilient professionals.

A captivating tale of a developer’s obsession and a journey into the less-trodden paths of Kotlin development was shared by Márton Braun, a Developer Advocate at JetBrains. It all began with a simple, yet compelling, observation at a previous KotlinConf: a screen saver featuring the bouncing Kotlin logos, reminiscent of old DVD players. Upon discovering it was merely a pre-rendered video and not a true screen saver, a challenge was born. Márton set out to build his own, a native macOS application powered by Kotlin/Native.

The project became a masterclass in interoperability and a candid exploration of the quirks of native application development. Márton detailed how Kotlin/Native’s powerful interop capabilities made it surprisingly easy to call native macOS APIs. However, this ease was often contrasted with the complexities and frustrations of working with the macOS platform itself. The development process was a constant battle, with macOS often proving to be an uncooperative partner in this creative endeavor.

Márton’s perseverance paid off, resulting in a fully functional screen saver. He even managed to create two distinct implementations: one using the traditional AppKit framework and another built with Compose Multiplatform. This dual approach not only demonstrated the capabilities of both technologies but also provided a unique learning experience. He highlighted how the Compose version allowed him to focus on the core UI logic, abstracting away the intricacies of packaging the screen saver. This is a powerful testament to Compose Multiplatform’s potential for simplifying development and improving productivity.

The screen saver project serves as an excellent case study, showcasing Kotlin’s ability to venture into unconventional domains beyond mobile and backend development. Márton successfully demonstrated that with Kotlin and the right tools, developers can create truly native applications for platforms like macOS, leveraging their existing skills and knowledge. The flexibility of Kotlin Multiplatform allows developers to share code across platforms while still delivering a native user experience.

Ultimately, this project is a celebration of the unique possibilities that Kotlin offers. It encourages developers to think creatively about how they can apply the language to solve a wide range of problems and build applications for a diverse set of platforms. Márton’s story is an inspiring reminder that sometimes the most interesting and valuable projects are born from a simple desire to see something that doesn’t exist yet come to life.

The rapid advancements in Artificial Intelligence, particularly in large language models (LLMs), are enabling the creation of more sophisticated and autonomous AI agents – programs capable of understanding instructions, reasoning, and interacting with their environment to achieve goals. Building such agents requires effective ways for the AI model to communicate programmatically and to trigger external actions. Julien Dubois, in his deep-dive session, explored key techniques and a new protocol essential for constructing these agentic AI systems: Structured Outputs, Function Calling, and the Model-Controller Protocol (MCP). Using practical examples and the latest Java SDK developed by OpenAI, he demonstrated how to implement these features within LangChain4j, showcasing how developers can build AI agents that go beyond simple text generation.

Structured Outputs: Enabling Programmatic Communication

One of the challenges in building AI agents is getting LLMs to produce responses in a structured format that can be easily parsed and used by other parts of the application. Julien explained how Structured Outputs address this by allowing developers to define a specific JSON schema that the AI model must adhere to when generating its response. This ensures that the output is not just free-form text but follows a predictable structure, making it straightforward to map the AI’s response to data objects in programming languages like Java. He demonstrated how to provide the LLM with a JSON schema definition and constrain its output to match that schema, enabling reliable programmatic communication between the AI model and the application logic. This is crucial for scenarios where the AI needs to provide data in a specific format for further processing or action.

Function Calling: Giving AI the Ability to Act

To be truly agentic, an AI needs the ability to perform actions in the real world or interact with external tools and services. Julien introduced Function Calling as a powerful mechanism that allows developers to define functions in their code (e.g., Java methods) and expose them to the AI model. The LLM can then understand when a user’s request requires calling one of these functions and generate a structured output indicating which function to call and with what arguments. The application then intercepts this output, executes the corresponding function, and can provide the function’s result back to the AI, allowing for a multi-turn interaction where the AI reasons, acts, and incorporates the results into its subsequent responses. Julien demonstrated how to define function “signatures” that the AI can understand and how to handle the function calls triggered by the AI, showcasing scenarios like retrieving information from a database or interacting with an external API based on the user’s natural language request.

MCP: Standardizing LLM Interaction

While Structured Outputs and Function Calling provide the capabilities for AI communication and action, the Model-Controller Protocol (MCP) emerges as a new standard to streamline how LLMs interact with various data sources and tools. Julien discussed MCP as a protocol that aims to standardize the communication layer between AI models (the “Model”) and the application logic that orchestrates them and provides access to external resources (the “Controller”). This standardization can facilitate building more portable and interoperable AI agentic systems, allowing developers to switch between different LLMs or integrate new tools and data sources more easily. While details of MCP might still be evolving, its goal is to provide a common interface for tasks like function calling, accessing external knowledge, and managing conversational state. Julien illustrated how libraries like LangChain4j are adopting these concepts and integrating with protocols like MCP to simplify the development of sophisticated AI agents. The presentation, rich in code examples using the OpenAI Java SDK, provided developers with the practical knowledge and tools to start building the next generation of agentic AI applications.

By leveraging techniques like Halo’s Gate to locate unhooked functions, HookChain ensures malicious payloads operate invisibly, achieving an impressive 66% success rate against top EDR products listed in Gartner’s Magic Quadrant.

Testing and Vendor Responses

Helvio shared results from testing HookChain against various EDR solutions, including remote process injection and credential dumping with tools like Mimikatz. His findings revealed that while some vendors, such as SentinelOne, implemented patches to counter HookChain, others lagged in response. He emphasized the importance of open collaboration, noting that two vendors engaged with him to test mitigations. Helvio’s transparency, including sharing his whitepaper and source code on GitHub, encourages the community to refine and challenge his techniques, fostering stronger defenses.

Future Directions for Cybersecurity

Concluding, Helvio urged the DEF CON community to embrace continuous innovation in security research. HookChain not only exposes vulnerabilities in current EDR systems but also paves the way for more adaptive solutions.

Håvard Opheim, a software developer at Kaa, took the audience at NDC Security 2025 in Oslo on a captivating journey through the history of the Morris Worm, the first significant malware to disrupt the early internet. Through a blend of historical narrative and technical analysis, Håvard explored the worm’s impact, its technical mechanisms, and the enduring lessons it offers for modern cybersecurity. His talk, rich with anecdotes and technical insights, highlighted how vulnerabilities exploited in 1988 remain relevant today.

The Dawn of the Morris Worm

Håvard set the stage by describing the internet of 1988, a nascent network connecting research institutions and defense installations via ARPANET. With minimal security controls, this “walled garden” fostered trust among users, allowing easy data sharing but also exposing systems to exploitation. On November 2, 1988, the Morris Worm, created by Cornell graduate student Robert Morris, brought this trust to its knees. Håvard recounted how the worm rendered computers across North America unusable, affecting universities, NASA, and the Department of Defense.

The worm’s rapid spread, Håvard explained, was not a deliberate attack but the result of a coding error by Robert. Intended as a proof-of-concept to highlight internet vulnerabilities, the worm’s aggressive replication turned it into a denial-of-service (DoS) fork bomb, overwhelming systems. Håvard’s narrative brought to life the chaos of that night, with system administrators scrambling to mitigate the damage as the worm reinfected systems despite reboots.

Technical Exploits and Vulnerabilities

Delving into the worm’s mechanics, Håvard outlined its exploitation of multiple vulnerabilities. The worm targeted Unix-based systems, leveraging flaws in the finger and sendmail programs. The finger daemon, used to query user information, suffered from a buffer overflow vulnerability due to the gets function, which lacked bounds checking. By sending a 536-byte payload—exceeding the 512-byte buffer—the worm overwrote memory to execute a remote shell, granting attackers full access.

Similarly, the sendmail program, running in debug mode on BSD 4.2 and 4.3, allowed commands in the recipient field, enabling the worm to send itself as an email and execute on the recipient’s system. Håvard also highlighted the worm’s password-cracking capabilities, exploiting predictable user behaviors, such as using usernames as passwords or simple variations like reversed usernames. These flaws, combined with insecure remote execution tools like rexec and rsh, allowed the worm to propagate rapidly across trusted networks.

Response and Legacy

Håvard described the community’s swift response, with ad-hoc working groups at Berkeley and MIT dissecting the worm overnight. By November 3, 1988, researchers had identified and patched the vulnerabilities, and within days, the worm’s source code was decompiled, revealing its inner workings. The incident, Håvard noted, marked a turning point, introducing the term “internet” to mainstream media and prompting the creation of the Computer Emergency Response Team (CERT).

The legal aftermath saw Robert convicted under the newly enacted Computer Fraud and Abuse Act (CFAA) of 1986, the first such conviction. Despite the worm’s benign intent, its impact—estimated at 100,000��10 million in damages—underscored the need for robust cybersecurity. Håvard emphasized that Robert’s career rebounded, with contributions to e-commerce and the founding of Y Combinator, but the incident left a lasting mark on the industry.

Enduring Lessons for Cybersecurity

Reflecting on the worm’s legacy, Håvard highlighted its relevance to modern cybersecurity. The vulnerabilities it exploited—buffer overflows, weak passwords, and insecure configurations—persist in today’s systems, albeit in patched forms. He stressed that human behavior remains a weak link, with users still prone to predictable password patterns. The worm’s unintended DoS effect also serves as a cautionary tale about the risks of untested code in production environments.

Håvard advocated for proactive measures, such as regular patching, strong authentication, and threat modeling, to mitigate similar risks today. He underscored the importance of learning from history, noting that the internet’s growth has amplified the stakes. By understanding past incidents like the Morris Worm, developers can build more resilient systems, recognizing that no system is inherently secure.

Lecturer

Clinton Herget serves as Field CTO at Snyk, advocating seamless security integration into developer workflows. Craig Lambert holds the position of Senior Director of Application Security and Red Team at Intercontinental Exchange (ICE), overseeing protective measures for 1,600 applications supporting 4,000 developers.

Abstract

This scholarly inquiry contrasts historical and contemporary software development paradigms, illuminating the cultural and technical metamorphosis required for effective DevSecOps institutionalization. Drawing upon ICE’s extensive implementation supported by Snyk tooling, the analysis examines incentive restructuring, unified risk aggregation, business-contextualized inventory management, and prospective advancements toward declarative security models. Particular emphasis falls upon transitioning from retrospective audits to continuous, developer-empowering safeguards that preserve innovation velocity.

Paradigmatic Shifts in Software Risk Topography and Development Velocity

Traditional software engineering operated within protracted waterfall cycles characterized by functional silos, monolithic codebases, and minimal external dependencies. Modern methodologies invert these conventions: continuous deployment rhythms, cross-functional platform teams, agile sprint cadences, microservices decomposition, and expansive supply chains incorporating open-source components, containerization, and application programming interfaces.

This transformation exponentially expands the attack surface while compressing release timelines, rendering conventional security approaches—periodic external audits, disconnected scanning regimes, documentation-heavy reporting—obsolete and friction-inducing.

DevSecOps emerges as the corrective philosophy, embedding protective controls throughout the software delivery lifecycle rather than appending them post-facto. Nevertheless to achieve parity between development pace and security rigor.

Cultural Realignment and Technical Integration Strategies at Intercontinental Exchange

ICE, encompassing the New York Stock Exchange alongside derivatives, fixed-income, and mortgage technology platforms, digitizes historically analog financial processes to enhance market transparency and operational efficiency. Safeguarding 1,600 applications for 4,000 developers demands security mechanisms that augment rather than impede productivity.

Cultural realignment commences with developer empowerment through instrumentation embedded directly within integrated development environments and continuous integration pipelines. Snyk facilitates immediate vulnerability feedback and automated remediation suggestions at the point of code commitment, transforming security from obstruction to augmentation.

Incentive architectures evolve correspondingly: gamification initiatives, security champion programs, and explicit accountability assignment to product owners establish shared ownership. These mechanisms balance velocity imperatives with protective diligence.

Technical consolidation aggregates disparate signals—static application security testing, dynamic application security testing, software composition analysis, infrastructure-as-code validation—into cohesive, actionable risk scoring. This unification filters extraneous noise, presenting developers with prioritized, context-enriched findings.

\# Example Snyk integration within CI/CD pipeline
stages:
  - security_scan
security_scan:
  script:
    - snyk auth $SNYK_TOKEN
    - snyk test --severity-threshold=critical
    - snyk iac test --target-reference=infra/
  artifacts:
    reports:
      junit: snyk_report.xml

Inventory contextualization represents the subsequent sophistication layer, mapping technical assets against business criticality and operational dependencies. This abstraction enables generic yet organizationally resonant policy enforcement.

Identified deficiencies include correlation between static and dynamic analysis for enhanced accuracy, declarative security specifications mirroring infrastructure-as-code principles, and machine learning orchestration of complex workflows from primitive signals.

Prospective Trajectories and Organizational Consequences of Mature DevSecOps Practice

Emerging capabilities envision machine learning systems synthesizing multifaceted telemetry to enable “security as code” paradigms. Developers articulate desired threat postures declaratively; underlying platforms dynamically enforce compliance across heterogeneous environments.

Organizational ramifications encompass accelerated innovation cycles unencumbered by security debt, systematic risk compression through proactive identification, and cultural cohesion wherein protective responsibility permeates all engineering disciplines. The ICE exemplar demonstrates that developer-centric security constitutes not merely technical integration but profound philosophical alignment.
