Trust Amplification Exploits In Human To Ai Security Teams Abusing Overconfidence In Automated Recommendations, Pranav Bhatanagar Mr Feb 2026

Trust Amplification Exploits In Human To Ai Security Teams Abusing Overconfidence In Automated Recommendations, Pranav Bhatanagar Mr

Defensive Publications Series

Human–AI collaboration has become a central component of modern cybersecurity operations. Security analysts increasingly rely on automated systems for threat detection, risk assessment, and incident response. While this collaboration improves efficiency and scalability, it also introduces new vulnerabilities associated with human trust in machine generated recommendations. This paper introduces Trust Amplification Exploits, a novel class of adversarial strategies that manipulate and exploit overconfidence in AI-assisted security workflows. Rather than targeting algorithms directly, these attacks leverage repeated system accuracy, interface design, and organizational dependence to amplify human reliance on automated outputs. Over time, excessive trust reduces critical evaluation and increases susceptibility …


Epistemic Corruption Attacks: Poisoning What Ai Security Systems “Know” Rather Than What They “Do”, Pranav Bhatanagar Mr Feb 2026

Epistemic Corruption Attacks: Poisoning What Ai Security Systems “Know” Rather Than What They “Do”, Pranav Bhatanagar Mr

Defensive Publications Series

As artificial intelligence becomes central to modern cybersecurity operations, defensive systems increasingly rely on internal knowledge representations, long-term memory modules, and retrieval-based reasoning mechanisms. These components enable adaptive learning and contextual awareness, but they also introduce a largely unexamined security vulnerability: the integrity of what the system knows. Existing research on AI security has primarily focused on attacks that manipulate outputs, bypass detection mechanisms, or compromise execution pathways. Far less attention has been given to attacks that corrupt internal knowledge structures themselves. This paper introduces Epistemic Corruption Attacks, a novel class of adversarial strategies that target the belief systems, embeddings, …


Interpretation Attacks: Exploiting How Ai Explains And Justifies Decisions (Turning Explainability Itself Into An Attack Surface), Pranav Bhatanagar Mr Feb 2026

Interpretation Attacks: Exploiting How Ai Explains And Justifies Decisions (Turning Explainability Itself Into An Attack Surface), Pranav Bhatanagar Mr

Defensive Publications Series

Explainable Artificial Intelligence (XAI) systems are widely promoted as mechanisms for increasing transparency, trust, and accountability in automated decision-making. By providing human-readable explanations for model outputs, these systems are intended to support oversight, regulatory compliance, and informed human judgment. However, the growing reliance on automated explanations has created a previously overlooked security risk: the explanations themselves can be manipulated, exploited, and weaponized. This paper introduces Interpretation Attacks, a class of adversarial strategies that target how AI systems generate, present, and justify their decisions. Rather than manipulating model predictions directly, these attacks exploit the interpretability layer to influence human perception, distort …


Intent-Obfuscation Attacks: Evading Ai Security By Manipulating Meaning, Pranav Bhatanagar Mr Feb 2026

Intent-Obfuscation Attacks: Evading Ai Security By Manipulating Meaning, Pranav Bhatanagar Mr

Defensive Publications Series

As artificial intelligence systems increasingly rely on intent-based security mechanisms to regulate user behavior, the nature of adversarial interaction is undergoing a subtle but significant shift. Rather than attempting to bypass safeguards through explicit policy violations or recognizable malicious patterns, attackers are increasingly manipulating meaning itself. This paper introduces Intent-Obfuscation Attacks, a class of semantic evasion techniques that exploit the gap between surface-level language compliance and the underlying objectives inferred by AI systems. Unlike traditional prompt injection or keyword-based attacks, intent-obfuscation operates through linguistic ambiguity, contextual indirection, and gradual semantic drift. Individual interactions appear benign and policy-compliant, yet when interpreted …


Ai Supply-Chain Pentesting: Attacking Models Through Training, Updates, And Dependencies (Hacking Ai Without Touching Production Systems.), Pranav Bhatanagar Mr Feb 2026

Ai Supply-Chain Pentesting: Attacking Models Through Training, Updates, And Dependencies (Hacking Ai Without Touching Production Systems.), Pranav Bhatanagar Mr

Defensive Publications Series

As artificial intelligence systems become embedded in critical decision-making workflows, security research has largely focused on defending models at runtime. Attention has centered on prompt injection, inference-time abuse, and output manipulation, implicitly assuming that models arrive in production as trustworthy artifacts. This assumption is increasingly fragile. Modern AI systems are assembled through complex and opaque supply chains involving datasets, pre-trained models, fine-tuning pipelines, dependency ecosystems, and automated update mechanisms. Each stage introduces opportunities for adversarial influence that remain largely unexplored by conventional security testing. This paper examines AI security from a supply-chain perspective, arguing that many impactful compromises occur upstream, …


Ai-Based Pentesting Of Ai Systems Recursive Security Failures, Pranav Bhatanagar Mr Feb 2026

Ai-Based Pentesting Of Ai Systems Recursive Security Failures, Pranav Bhatanagar Mr

Defensive Publications Series

The rapid adoption of artificial intelligence within cybersecurity has fundamentally altered both defensive and offensive security practices. In recent years, AI driven tools have increasingly been deployed not only to protect systems, but also to test them. Automated scanners, autonomous red teaming agents, and AI assisted penetration testing platforms are now capable of probing complex infrastructures at a speed and scale that far exceed human capability. At the same time, modern production environments themselves are becoming increasingly dependent on AI based components, including adaptive intrusion detection systems, behavioural firewalls, anomaly detection engines, and large language model driven control interfaces. This …

The Racial Politics Of Early Dentistry And The Terrible “Toothache Blues”, Bronwen Mcveigh Phd Feb 2026

The Racial Politics Of Early Dentistry And The Terrible “Toothache Blues”, Bronwen Mcveigh Phd

Journal of the American College of Dentists

In interwar America, the relatively young profession of dentistry was developing rapidly. As the government, health institutions, and social organizers focused more intently on notions of national wellness, questions about how to achieve a healthy smile—and what a healthy smile should look like—proliferated. Groups like the National Dental Association worked to establish rigorous standards of technique, define ethical behavior, and encourage dentists to develop business acumen, yet the surprising proliferation of blues songs about dubious dentists tricking unassuming clients, or about fraught love affairs allegorized by disastrous dental exams, highlights the equivocal nature of many developments in early dentistry.

Ex Vivo Microfluidic Model Identifies A Role For Shear Stress During Ovarian Tumor Cell Attachment To Peritoneal Mesothelial Cells, Vasilios A Morikis, Breanna Baker, Jillian A Martin, Angela Schab, Alessandra Dimauro, Gregory D Longmore, Whitney R Grither

2020-Current year OA Pubs

Ascites, or a pathologic accumulation of intra-abdominal fluid, is a key feature of intraperitoneally disseminating cancers, such as ovarian cancer. This pathological fluid buildup can influence the adhesive abilities of ovarian cancer cells, as they spread throughout the abdominal cavity to form metastatic implants on organs lined with a specialized monolayer of mesothelial cells. Robust methods for assessing the impact of fluid shear stress on this cell-cell interaction are lacking. Here, we develop and characterize a novel microfluidic device that allows for the determination of the attachment of ovarian tumor cells to mesothelial cells under the influence of fluid flow. …

The Dental Phantom As A Tool For Exploring Fear, The Face, And Dental Education, Christine Slobogin Phd Feb 2026

The Dental Phantom As A Tool For Exploring Fear, The Face, And Dental Education, Christine Slobogin Phd

Journal of the American College of Dentists

Dental phantoms have been used in dental education since the late nineteenth century. These pedagogical objects – particularly those from the first half of the twentieth century – have today enjoyed a resurgence of interest in the art and film worlds. After first outlining the history and pedagogical purposes of the dental phantom, this article examines what the artistic and filmic attractions to the aesthetics of these objects can tell us about fear, the mouth and the face, and dental education. How and why can a dental teaching tool be scary? Arriving at some answers to this question – reached …

The Vipeholm Experiments: A Case Study Of Unethical Dental Research, Lainie Ross Md, Phd Feb 2026

The Vipeholm Experiments: A Case Study Of Unethical Dental Research, Lainie Ross Md, Phd

Journal of the American College of Dentists

Modern-day research ethics training often begins with a discussion of the medical research atrocities committed by Nazi health care professionals and the resulting 10-principle Nuremberg Code, which is often considered to be the beginning of modern-day medical research regulations. It is occasionally mentioned that Nazi dentists also conducted unethical research in the concentration camps, and a few were brought to trial. In this manuscript, I compare two studies (one medical and one dental) conducted after World War II that violated the Nuremberg Code.

I describe and compare the well-known Willowbrook Hepatitis studies conducted by infectious disease doctors on vulnerable institutionalized …

Can Palm Logs Float? Evaluating The Physical Viability Of Raft Transport For Rapa Nui Moai, Carl Philipp Lipo, Terry L. Hunt Feb 2026

Can Palm Logs Float? Evaluating The Physical Viability Of Raft Transport For Rapa Nui Moai, Carl Philipp Lipo, Terry L. Hunt

Anthropology Datasets

Recent suggestions that palm log rafts may have transported moai statues on Rapa Nui require evaluation of whether fresh palm wood can provide sufficient buoyancy for multi-ton cargo. This analysis integrates experimental flotation tests, structural analyses of palm stem anatomy, and buoyancy calculations using modern palm analogs to reconstruct the extinct Rapa Nui palm. Fresh palm logs sink when placed in water because of their internal structure: stems consist of approximately 20% liquid by volume, contained within thousands of water-filled vascular tubes, surrounded by a thin, brittle cortex. This yields effective densities of 800-1,200 kg/m³ that approach or exceed seawater …


Information Distortion As A Source Of Overconfidence In Managerial Decisions, Peter Boyle, Pete Nye Feb 2026

Information Distortion As A Source Of Overconfidence In Managerial Decisions, Peter Boyle, Pete Nye

All Faculty Scholarship for the College of the Sciences

Managers confronting important strategic decisions often receive diagnostic information sequentially over time. As new information becomes available, they may need to update their understanding of the situation and possibly revise their preferences. During a decision, as a preference develops for one alternative course of action, a nonconscious goal of maintaining consistency between that preference, however tentative, and the new information can lead to an interpretation of that information so as to support the current preference. This tendency to bias or distort information to support the currently preferred option can in turn lead to even greater confidence in that leading option, …
