[DefCon32] How to Keep IoT From Becoming An IoTrash
The proliferation of Internet of Things (IoT) devices promises connectivity but risks creating a digital wasteland of abandoned, vulnerable gadgets. Paul Roberts, Chris Wysopal, Cory Doctorow, Tarah Wheeler, and Dennis Giese, a distinguished panel from Secure Resilient Future Foundation, Electronic Frontier Foundation, Veracode, Red Queen Dynamics, and DontVacuum.me, respectively, address this crisis. Their discussion, rooted in cybersecurity and policy expertise, explores solutions to prevent IoT devices from becoming e-waste, advocating for transparency, ownership, and resilience.
The Growing Threat of Abandonware
Paul opens by highlighting the scale of the issue: end-of-life devices, from routers to medical equipment, are abandoned by manufacturers, leaving them susceptible to exploitation. Black Lotus Labs’ discovery of 40,000 compromised SOHO routers in the “Faceless” botnet underscores this danger. Cory introduces the concept of “enshittification,” where platforms and devices degrade as manufacturers prioritize profits over longevity, citing Spotify’s Car Thing, bricked without refunds after brief market presence.
Policy and Right-to-Repair Solutions
Tarah and Chris advocate for legislative reforms, such as updating the Digital Millennium Copyright Act (DMCA), to grant consumers repair rights. Google’s extension of Chromebook support to ten years saved millions in e-waste, a model Tarah suggests for broader adoption. Chris emphasizes that unmaintained devices fuel botnets, threatening critical infrastructure. Policy changes, including antitrust enforcement to curb monopolistic practices, could compel manufacturers to prioritize device longevity and security.
Cybersecurity Implications and Community Action
Dennis, known for reverse-engineering vacuum robots, stresses the cybersecurity risks of abandoned devices. Malicious actors exploit unpatched vulnerabilities, conscripting devices into botnets. He calls for community-driven efforts to document and secure IoT systems. Paul, through the Secure Resilient Future Foundation, encourages grassroots advocacy, such as contacting local representatives to support repair-friendly legislation, making it easier for individuals to contribute without navigating complex policy landscapes.
Redefining Ownership and Sustainability
Cory argues for redefining ownership in the IoT era, criticizing practices like Adobe’s Creative Cloud, where Pantone’s licensing dispute threatened to render designers’ work unusable. By designing devices to resist forced downgrades, manufacturers can empower users to maintain control. The panel collectively urges a shift toward sustainable design, where devices remain functional through community-driven updates, reducing e-waste and enhancing digital resilience.

[DefCon32] Listen to the Whispers: Web Timing Attacks that Actually Work
Timing attacks, long dismissed as theoretically potent yet practically elusive, gain new life through innovative techniques. James Kettle bridges the “timing divide,” transforming abstract concepts into reliable exploits against live systems. By amplifying signals and mitigating noise, Kettle unveils server secrets like masked misconfigurations, blind injections, hidden routes, and untapped attack surfaces.
Traditional hurdles—network jitter and server noise—once rendered attacks unreliable. HTTP/2’s concurrency, enhanced by Kettle’s single-packet method, synchronizes requests in one TLS record, eliminating jitter. Coalescing headers via sacrificial PING frames counters sticky ordering, making attacks “local” regardless of distance.
Server noise, from load variances to cloud virtualization, demands signal amplification: repeating headers for cumulative delays or denial-of-service tactics like nested XML entities. Repetition exploits caching, reducing variability; trimming requests minimizes unnecessary processing.
Parameter Discovery and Control Flow Insights
Kettle adapts Param Miner for time-based parameter/header guessing, uncovering hidden features on thousands of bug bounty sites. Timing reveals parameters altering responses subtly, like JSON-validated headers or cache keys signaling web cache poisoning risks.
Control flow changes, such as exceptions, emerge vividly. A Web Application Firewall (WAF) bypass exemplifies: repeated “exec” parameters trigger prolonged analysis, escalating to denial-of-service; excess parameters expose max-header limits, enabling evasion.
IP spoofing headers like “True-Client-IP” induce DNS caching delays, confirmed via pingbacks. Non-caching variants suggest third-party geo-lookups, bypassing with hostnames.
Server-Side Injection Vulnerabilities
Timing excels at blind injections in non-sleep-capable languages. Serde JSON injections manifest as microsecond differentials; combining with client-side reflections infers standalone processing, aiding exploitation.
Blind Serde parameter pollution contrasts reserved/unreserved characters, yielding exploits. Doppelgangers—non-blind equivalents—guide understanding, turning detections into impacts.
SQL injections via sleep evade WAFs but overlap existing tools; timing shines where sleep fails, though exploitation demands deep target insight.
Scoped Server-Side Request Forgery Detection
Overlooked for years, scoped SSRF—proxies accessing only target subdomains—defies DNS pingbacks. Timing detects via DNS caching or label-length timeouts: valid hostnames delay; invalids accelerate or prolong.
Automating exploration, Kettle probes subdomains directly and via proxies, flagging discrepancies like missing headers. Exploits span firewall bypasses, internal DNS resolutions uncovering staging servers, pre-launch consoles, and frontend circumventions.
Frontend impersonation leverages trusted internal headers for authentication bypasses, exploitable via proxies, direct backend access, or smuggling. Timing guesses header names, enabling severe breaches.

[DefCon32] Breaking Secure Web Gateways for Fun and Profit
Secure Web Gateways (SWGs), integral to enterprise Secure Access Service Edge (SASE) and Security Service Edge (SSE) frameworks, promise robust defenses against web threats. Vivek Ramachandran and Jeswin Mathai expose architectural flaws in these systems, introducing “Last Mile Reassembly Attacks” that evade detection across major vendors. Their findings underscore the limitations of network-level analysis in confronting modern browser capabilities.
SWGs intercept SSL traffic for malware scanning, threat prevention, URL filtering, and data loss prevention (DLP). Yet, as browsers evolve into sophisticated compute environments, attackers exploit client-side processing to reassemble threats post-proxy. Ramachandran highlights how SWGs lack context on DOM changes, events, and user interactions, operating blindly on flat traffic. Cloud constraints—file size limits (15-50 MB) and incomplete archive scanning—exacerbate vulnerabilities, often forcing blanket policies.
Vendors’ service level agreements (SLAs) claim 100% prevention of known malware, but these attacks shatter such guarantees. Pricing models ($2-4 per user/month) prioritize efficiency over exhaustive analysis, leaving gaps in protocol support and file handling.
Unmonitored Channels and Hiding in Plain Sight
Mathai demonstrates unmonitored protocols like WebRTC, WebSockets, gRPC, and Server-Sent Events smuggling malware undetected. These channels, essential for real-time apps, bypass interception; blocking them degrades user experience. Demos show seamless downloads of known malicious files via these vectors, indistinguishable from standard HTTP.
Further evasion involves embedding payloads in HTML, CSS, JavaScript, or SVG, extracting them client-side for reconstruction. SWGs scan individual resources but miss browser-side assembly. Encryption/decryption and encoding/decoding (e.g., Base64, UUencode) transform binaries in memory, dropping unencrypted files without triggering content disposition headers.
Last Mile Reassembly Techniques
Core to their research, Last Mile Reassembly fragments files into chunks—straight splits, reverses, randomized sizes, or mixes—fetched via multiple requests and reassembled via JavaScript. SWGs analyze fragments independently, failing to detect malice. Extending to WebAssembly modules constructing documents (e.g., malicious Excel) locally, no file download occurs from the proxy’s view.
File uploads reverse this: insiders fragment sensitive data, sending as form submissions evading DLP rules. Overlapping fragments mimic historical network attacks, fully bypassing inspections.
Phishing sites, converted to MHTML archives and smuggled via reassembly, repaint via canvas, reusing known malicious pages undetected. SWGs fingerprint server-side but overlook client-side rendering.
Architectural Challenges and Vendor Responses
SWGs’ server-side nature precludes real-time browser syncing or per-tab emulation, unscalable amid millions of events. Ramachandran argues for browser-integrated security to access rich data, contrasting cloud-centric models’ economic allure with practical failures.
Vendor engagements yielded mixed results: some acknowledged issues and pursued fixes; others claimed partial detection or disengaged. Open-sourcing 25 bypasses at browser.security empowers testing, urging vendors to address rather than block the site.
Their toolkit facilitates red-team simulations, exposing SLAs’ fragility. Enterprises must rethink web threat defenses, prioritizing client-side visibility over network proxies.

[DefCon32] Abusing Windows Hello Without a Severed Hand
In the realm of cybersecurity, exploring vulnerabilities in authentication mechanisms often reveals unexpected pathways for exploitation. Ceri Coburn and Dirk-jan Mollema delve into the intricacies of Windows Hello, Microsoft’s passwordless technology, highlighting how attackers can manipulate its components without relying on physical biometric data. Their presentation uncovers the architecture of Windows Hello, from key storage providers to protectors and keys, demonstrating real-world abuses that challenge the system’s perceived robustness.
Coburn begins by outlining the foundational elements of Windows Hello, emphasizing its role in generating keys for operating system logins, passkeys, and third-party applications. The distinction between Windows Hello and Windows Hello for Business lies primarily in the latter’s focus on certificate-based authentication for Active Directory environments. Both utilize key storage providers (KSPs), which serve as APIs for cryptographic operations. Traditional providers include software-based ones, TPM-backed platforms, and smart card integrations, but Windows Hello introduces the Passport KSP, acting as a proxy to these existing systems.
The Passport KSP comprises two services: the NGC service for application communication via RPC and the NGC controller service for metadata storage under the local service account, accessible only with system-level privileges. Each user enrollment creates a unique container folder identified by a GUID, housing protectors, key metadata, and recovery options. Protectors represent authentication methods like PINs or biometrics, encrypting intermediate PINs that unlock enrolled keys. These intermediate PINs—split into signing, decryption, and external variants—remain constant across protectors, allowing bypasses once accessed.
Unprivileged Attacks and Primary Refresh Tokens
Shifting focus, Mollema addresses attacks feasible without administrative privileges, centering on Primary Refresh Tokens (PRTs) in Windows Hello for Business scenarios. PRTs function as single sign-on tokens, requested via JSON Web Tokens (JWTs) signed by device certificates, ensuring trust from Entra (formerly Azure AD). When using Windows Hello, these requests incorporate data signed by private keys, including nonces to prevent replays.
A critical flaw arises from the ability to generate assertions without prompting for PINs or biometrics post-login, as keys are cached in sessions. Mollema demonstrates crafting “golden assertions” with extended validity, though Microsoft mitigated this by enforcing nonces server-side in May 2024. Nonetheless, within a five-minute window, attackers can request new PRTs on rogue devices, bypassing TPM protections and enabling persistence for up to 90 days.
This technique exploits RDP scenarios where PRTs on non-TPM devices expose credentials. Even with virtualization-based security or LSA protections, such attacks persist, underscoring the need for device compliance monitoring and restrictions on RDP to non-TPM systems.
Privileged Exploitation of Containers and Protectors
Under privileged access, Coburn dissects container structures, revealing metadata in .dat files detailing user SIDs, backing KSPs, and recovery keys. Protectors encrypt intermediate PINs differently: PIN protectors use PBKDF2 derivation for software KSPs or hex conversion for TPM unsealing. Biometric protectors, surprisingly, rely on system DPAPI keys, enabling reversal without actual biometrics via Vault decryption.
Recovery protectors, exclusive to business scenarios, involve Azure-encrypted blobs requiring MFA claims, yet their storage outside protector folders poses risks. Pre-boot and deprecated companion device protectors receive brief mentions, with further research needed.
Abuses include brute-forcing software-backed PINs via Hashcat masks, exploiting known lengths for rapid cracks—seconds for eight digits. TPM-backed PINs resist better, though four-digit variants succumb in months due to anti-hammering.
Key Types and Persistence Implications
Enrolled keys leverage intermediate PINs: vault keys decrypt local passwords in consumer setups, entry keys handle business enrollments and passkeys, and external keys support third-party apps like Okta FastPass. Software-backed keys allow extraction off-device, amplifying risks.
Mollema extends this to PRT theft, using cached keys for assertions on different devices, even without TPMs, facilitating identity persistence. Reported vulnerabilities led to CVE assignments, with server-side enforcements post-July 2023.
Endpoint mitigations include Windows Hello Extended Session Security (ESS), rewriting containers in JSON under secure processes. Detections monitor NGC metadata access, alerting on non-controller processes.
Their tools—Shay for Hello abuses and ROADtools for Azure AD—aid offensive and defensive efforts, drawing from blogs by Teal and others.

[DefCon32] OH MY DC: Abusing OIDC All the Way to Your Cloud
As organizations migrate from static credentials to dynamic authentication protocols, overlooked intricacies in implementations create fertile ground for exploitation. Aviad Hahami, a security researcher at Palo Alto Networks, demystifies OpenID Connect (OIDC) in the context of continuous integration and deployment (CI/CD) workflows. His examination reveals vulnerabilities stemming from under-configurations and misconfigurations, enabling unauthorized access to cloud environments. By alternating perspectives among users, identity providers, and CI vendors, Aviad illustrates attack vectors that compromise sensitive resources.
Aviad begins with foundational concepts, clarifying OIDC’s role in secure, short-lived token exchanges. In CI/CD scenarios, tools like GitHub Actions request tokens from identity providers (IdPs) such as GitHub’s OIDC provider. These tokens, containing claims like repository names and commit SHAs, are validated by workload identity federations (WIFs) in clouds like AWS or Azure. Proper configuration ensures tokens originate from trusted sources, but lapses invite abuse.
Common pitfalls include wildcard allowances in policies, permitting access from unintended repositories. Aviad demonstrates how fork pull requests (PRs) exploit these, granting cloud roles without maintainer approval. Such “no configs” scenarios, where minimal effort yields high rewards, underscore the need for precise claim validations.
Advanced Configurations and Misconfigurations
Delving deeper, Aviad explores “advanced configs” that inadvertently become misconfigurations. Features like GitHub’s ID token requests for forks introduce risks if not explicitly enabled. He recounts discovering a vulnerability in CircleCI, where reusable configurations allowed token issuance to forks, bypassing protections.
Shifting to the IdP viewpoint, Aviad discloses a real-world flaw in a popular CI vendor, permitting token claims from any repository within an organization. This enabled cross-project escalations, compromising clouds via simple PRs. Reported responsibly, the issue prompted fixes, emphasizing the cascading effects of IdP errors.
He references Tinder’s research on similar WIF misconfigurations, reinforcing that even sophisticated setups falter without rigorous claim scrutiny.
Exploitation Through CI Vendors
Aviad pivots to CI vendor responsibilities, highlighting how their token issuance logic influences downstream security. In CircleCI’s case, a bug allowed organization-wide token claims, exposing multiple projects. By requesting tokens in fork contexts, attackers could satisfy broad WIF conditions, accessing clouds undetected.
Remediation involved opt-in mechanisms for fork tokens, mirroring GitHub’s approach. Aviad stresses learning claim origins per IdP, avoiding wildcards, and hardening pipelines to prevent trivial breaches.
His tool for auditing Azure CLI configurations exemplifies proactive defense, aiding in identifying exposed resources.
Broader Implications for Secure Authentication
Aviad’s insights extend beyond CI/CD, advocating holistic OIDC understanding to thwart supply chain attacks. By dissecting entity interactions—users, IdPs, and clouds—he equips practitioners to craft resilient policies.
Encouraging bounty hunters to probe these vectors, he underscores OIDC’s maturity yet persistent gaps. Ultimately, robust configurations transform OIDC from vulnerability to asset, safeguarding digital infrastructures.

[DefCon32] Where’s the Money? Defeating ATM Disk Encryption
In an era where automated teller machines safeguard substantial sums, vulnerabilities in their protective mechanisms pose significant threats. Matt Burch, an independent security researcher specializing in IoT and hardware, unveils critical flaws in Diebold Nixdorf’s Vynamic Security Suite (VSS), the dominant solution in the sector. His investigation, conducted alongside a colleague, exposes six zero-day issues enabling full system compromise within minutes, highlighting systemic risks across financial, gaming, and retail domains.
Matt’s journey stems from a fascination with the surge in ATM crimes, up over 600% recently. Targeting enterprise-grade units holding up to $400,000, he dissects VSS’s full disk encryption, revealing offline code injection and decryption paths. Diebold Nixdorf, one of three primary North American manufacturers with global reach, deploys VSS widely, including in Las Vegas casinos.
ATM architecture divides into a fortified vault for currency and a less secure “top hat” housing computing elements. The vault features robust steel, multi-factor locks, and tamper sensors, while the upper section uses thin metal and vulnerable locks, facilitating entry via simple tools.
VSS integrates endpoint protection, whitelisting, and encryption, yet Matt identifies gaps in its pre-boot authentication (PBA). This layered integrity check, spanning phases, fails to prevent unauthorized access.
Pre-Boot Authentication Vulnerabilities
VSS’s PBA employs a custom Linux-based “Super Sheep” OS for initial validation. Phase one mounts the Windows partition read-only, computing SHA-256 sums for critical files. Successful checks lead to phase two, decrypting and booting Windows.
Matt exploits unencrypted Linux elements, mounting drives offline to inject code. CVE-2023-33204 allows execution via root’s .profile, bypassing sums by targeting non-checked files. Demonstrations show callback shells post-reboot.
Service releases introduce patches, yet recursive flaws emerge. CVE-2023-33205 leverages credential stuffing on weak defaults, enabling admin escalation and command injection.
Recursive Flaws and Persistence
Patches inadvertently create new vectors. Service Release 15 removes directories but overlooks symlinks, leading to CVE-2023-33206. Attackers create traversal links, injecting payloads into root’s directory for execution.
Further updates validate symlinks, yet CVE-2023-40261 strips execute permissions from integrity modules, disabling VSS entirely. This permits arbitrary unsigned binaries, affecting all versions.
Impacts span VSS iterations, with vulnerabilities identified from April to July 2023. Diebold’s responses include end-of-life for older variants and redesigns.
Mitigation and Broader Implications
Defending requires patching to latest releases, enabling security checks to withhold TPM keys, and monitoring physical access. Disabling unused ports and securing drives reduce risks. Alternatives like BitLocker offer robust encryption.
Matt’s findings influence Diebold’s Version 4.4, introducing full Super Sheep encryption. Yet, persistent unencrypted elements suggest ongoing challenges, with likely undiscovered exploits.
This research underscores the need for comprehensive security in high-value systems, where physical and digital safeguards must align.

[DefCon32] Counter Deception: Defending Yourself in a World Full of Lies
The digital age promised universal access to knowledge, yet it has evolved into a vast apparatus for misinformation. Tom Cross and Greg Conti examine this paradox, tracing deception’s roots from ancient stratagems to modern cyber threats. Drawing on military doctrines and infosec experiences, they articulate principles for crafting illusions and, crucially, for dismantling them. Their discourse empowers individuals to navigate an ecosystem where truth is obscured, fostering tools and mindsets to reclaim clarity.
Deception, at its essence, conceals reality to gain advantage, influencing decisions or inaction. Historical precedents abound: the Trojan Horse’s cunning infiltration, Civil War quaker guns mimicking artillery, or the Persian Gulf War’s feigned amphibious assault diverting attention from a land offensive. In contemporary conflicts, like Russia’s Ukraine invasion, fabricated narratives such as the “Ghost of Kyiv” bolster morale while masking intentions. These tactics transcend eras, targeting not only laypersons but experts, code, and emerging AI systems.
In cybersecurity, falsehoods manifest at every layer: spoofed signals in the electromagnetic spectrum, false flags in malware attribution, or fabricated personas for network access and influence propagation. Humans fall prey through phishing, typo-squatting, or mimicry, while specialists encounter deceptive metadata or rotating infrastructures. Malware detection evades scrutiny via polymorphism or fileless techniques, and AI succumbs to data poisoning or jailbreaks. Strategically, deception scales from tactical engagements to national objectives, concealing capabilities or projecting alternatives.
Maxims of Effective Deception
Military thinkers have distilled deception into enduring guidelines. Sun Tzu advocated knowing adversaries intimately while veiling one’s own plans, emphasizing preparation and adaptability. Von Clausewitz viewed war—and by extension, conflict—as enveloped in uncertainty, where illusions amplify fog. Modern doctrines, like those from the U.S. Joint Chiefs, outline six tenets: focus on key decision-makers, integration with operations, centralized control for consistency, timeliness to exploit windows, security to prevent leaks, and adaptability to evolving conditions.
These principles manifest in cyber realms. Attackers exploit cognitive biases—confirmation, anchoring, availability—embedding falsehoods in blind spots. Narratives craft compelling stories, leveraging emotions like fear or outrage to propagate. Coordination ensures unified messaging across channels, while adaptability counters defenses. In practice, state actors deploy bot networks for amplification, or cybercriminals use deepfakes for social engineering. Understanding these offensive strategies illuminates defensive countermeasures.
Inverting Principles for Countermeasures
Flipping offensive maxims yields defensive strategies. To counter focus, broaden information sources, triangulating across diverse perspectives to mitigate echo chambers. Against integration, scrutinize contexts: does a claim align with broader evidence? For centralized control, identify coordination patterns—sudden surges in similar messaging signal orchestration.
Timeliness demands vigilance during critical periods, like elections, where rushed judgments invite errors. Security’s inverse promotes transparency, fostering open verification. Adaptability encourages continuous learning, refining discernment amid shifting tactics.
Practically, countering biases involves self-awareness: question assumptions, seek disconfirming evidence. Triangulation cross-references claims against reliable outlets, fact-checkers, or archives. Detecting narratives entails pattern recognition—recurring themes, emotional triggers, or inconsistencies. Tools like reverse image searches or metadata analyzers expose fabrications.
Applying Counter Deception in Digital Ecosystems
The internet’s structure amplifies deceit, yet hackers’ ingenuity can reclaim agency. Social media, often ego-centric, distorts realities through algorithmic funhouse mirrors. Curating expert networks—via follows, endorsements—filters noise, prioritizing credible voices. Protocols for machine-readable endorsements, akin to LinkedIn but open, enable querying endorsed specialists on topics, surfacing informed commentary.
Innovative protocols like backlinks—envisioned by pioneers such as Vannevar Bush, Douglas Engelbart, and Ted Nelson—remain underexplored. These allow viewing inbound references, revealing critiques or extensions. Projects like Xanadu or Hyperscope hint at potentials: annotating documents with trusted overlays, highlighting recent edits for scrutiny. Content moderation challenges stymied widespread adoption, but coupling with decentralized systems like Mastodon offers paths forward.
Large language models (LLMs) present dual edges: prone to hallucinations, yet adept at structuring unstructured data. Dispassionate analysis could unearth omitted facts from narratives, or map expertise by parsing academic sites to link profiles. Defensive tools might flag biases or inconsistencies, augmenting human judgment per Engelbart’s augmentation ethos.
Scaling countermeasures involves education: embedding media literacy in curricula, emphasizing critical inquiry. Resources like Media Literacy Now provide K-12 frameworks, while frameworks like “48 Critical Thinking Questions” prompt probing—who benefits, where’s the origin? Hackers, adept at discerning falsehoods, can prototype tools—feed analyzers, narrative detectors—leveraging open protocols for innovation.
Ultimately, countering deception demands vigilance and creativity. By inverting offensive doctrines, individuals fortify perceptions, transforming the internet from a misinformation conduit into a truth-seeking engine.
