Model Exploitation Risks: The CISO's Field Guide to the 2026 Threat Landscape

Updated May 8, 2026

By 2026, artificial intelligence is no longer an experiment; it is the central nervous system of the modern enterprise and a primary vector for high-stakes attacks. This analysis dissects the sophisticated threats of model exploitation, from corporate espionage via advanced prompt hacking to the catastrophic business interruption caused by data poisoning. We explore the multi-million dollar financial fallout of an AI breach and provide a CISO-level blueprint for defense, covering the secure AI lifecycle, continuous validation through red teaming, and navigating the increasingly complex AI insurance market.

1. The New Reality: AI as Critical Business Infrastructure

Two years is a lifetime in artificial intelligence. By 2026, the transition from AI as a novel technology to AI as a core business dependency is complete. Gartner's earlier predictions have been realized; their 2025 reports indicate that over 90% of large enterprises now deploy generative AI in customer-facing roles, with AI-driven decision-making embedded deeply within finance, supply chain management, and human resources. This integration, while delivering unprecedented efficiency and insight, has also created a new, highly sensitive class of critical infrastructure: the AI model itself.

Classic adversarial example: an imperceptible perturbation added to an input causes the model to misclassify with high confidence.

Unlike traditional software, which fails by crashing or producing an error, AI models fail by producing plausible but dangerously incorrect, biased, or malicious outputs. These are not simple bugs; they are systemic vulnerabilities in the model's logic, learned from data and susceptible to manipulation. When an AI model managing dynamic pricing for a global retailer is exploited, the result isn't a 404 error; it's a silent, multi-million dollar revenue leak. When a diagnostic AI is subtly compromised, the consequence can be misdiagnoses at scale, leading to immense liability and human cost.

This places CISOs in a challenging new position. The traditional security perimeter, focused on network and endpoint security, is no longer sufficient. The new battleground is the model itself—its training data, its architecture, and the prompts that govern its behavior. As ENISA, the EU's cybersecurity agency, highlighted in its 2025 AI Threat Landscape report, attacks are shifting from infrastructure-level compromises to logic-level manipulation. Threat actors are no longer just trying to break in; they are trying to mislead, corrupt, and steal the very intelligence that powers the business.

Understanding and mitigating these model exploitation risks is therefore not an IT problem, but a strategic business imperative. It requires a fundamental rethinking of security, governance, and risk management. The organizations that thrive in this new era will be those that treat their AI models with the same rigorous security discipline as their most sensitive financial systems and intellectual property databases. For a deeper understanding of the foundational principles, exploring the topic of AI Risk Management Framework is a crucial first step.

2. A Taxonomy of Threats: Deconstructing Model Exploitation

The term "model exploitation" covers a diverse and rapidly evolving set of attack techniques. To build an effective defense, security leaders must first understand the adversary's playbook. The MITRE ATLAS (Adversarial Threat Landscape for Artificial-Intelligence Systems) framework provides a crucial, standardized language for cataloging these threats, much as the ATT&CK framework did for traditional cyber tactics. By 2026, mapping defenses against ATLAS is becoming a standard practice for mature security organizations.

The major categories of model exploitation include:

Evasion Attacks: This is the most direct form of attack, where an adversary crafts an input designed to be misclassified by the model at the time of inference. Think of a spam filter being fooled by a carefully worded email or a facial recognition system being defeated by adversarial patterns printed on glasses. In 2026, these attacks have moved beyond academic proofs-of-concept to targeted tools used to bypass AI-powered fraud detection and content moderation systems at scale.
Poisoning Attacks: These are insidious 'supply chain' attacks against the model's learning process. An attacker introduces corrupt or maliciously crafted data into the training set, creating a hidden backdoor. The model may function perfectly 99.9% of the time, but when it encounters a specific trigger—a particular image, phrase, or data point—it executes the attacker's desired function, such as misclassifying data or granting unauthorized access. These are particularly dangerous because they are invisible in the deployed model until triggered. You can learn more about these specific threats in our guide on Data Poisoning Attacks.
Extraction Attacks: These attacks focus on stealing the model itself or the sensitive data it was trained on. In model extraction, an attacker queries the model API repeatedly to reconstruct a functionally equivalent copy, thereby stealing valuable intellectual property that may have cost millions to develop. In membership inference and other data extraction attacks, attackers craft queries that cause the model to leak fragments of its private training data, a catastrophic privacy breach if the model was trained on customer PII or sensitive corporate documents. These are a primary focus of our deep dive into Model Inversion Attacks.
Privacy Attacks: Closely related to extraction, these attacks specifically aim to compromise the privacy of individuals whose data was used in training. Techniques like membership inference, attribute inference, and data reconstruction can expose sensitive personal information, leading to massive regulatory fines under frameworks like GDPR and the (now fully implemented) EU AI Act. This is a critical consideration for developing Privacy-Preserving Machine Learning techniques.

Understanding this taxonomy is the first step in conducting a proper AI Threat Modeling exercise, allowing security teams to reason about a system’s specific vulnerabilities based on its architecture, data sources, and deployment method.

3. The Evolution of Prompt Hacking: From Pranks to Corporate Sabotage

What began in the early 2020s as a cat-and-mouse game of "jailbreaking" chatbots to bypass safety filters has, by 2026, matured into a sophisticated vector for corporate espionage and system compromise. The core technique, prompt injection, exploits the conflation of instruction and data in Large Language Models (LLMs). An attacker provides input that the model mistakes for a trusted developer instruction, causing it to override its original purpose.

Early prompt injection was direct, with users simply asking the model to ignore its previous instructions. The attacks of 2026 are far more subtle and dangerous, often involving indirect or "second-order" prompt injection. In this scenario, the malicious prompt is not injected by the user but is hidden within data that the model retrieves from an external source, such as a webpage, a document, or a database record. For example, an attacker might embed a malicious prompt in the 'About Us' page of a website. When a corporate AI assistant, tasked with summarizing recent news about a competitor, scrapes that page, the hidden prompt executes within the corporation's trusted environment.

As Mandiant's M-Trends 2025 report observes, threat actors are now weaponizing model vulnerabilities at a speed that rivals traditional software exploits, collapsing the window from discovery to mass exploitation from months to mere days. Advanced prompt injection payloads are being packaged and sold on dark web forums as "turnkey" solutions for data exfiltration.

The consequences are severe. A successful second-order prompt injection can:

Exfiltrate Data: The malicious prompt could instruct the LLM to append its conversation history (which might include sensitive data from other tasks) to a web request it makes, silently sending that data to an attacker-controlled server.
Manipulate Business Processes: An LLM integrated with an e-commerce backend could be instructed to apply a 100% discount code to the attacker's shopping cart. An AI agent managing calendar appointments could be tricked into deleting all Q3 executive meetings.
Propagate Through Systems: A compromised LLM can be instructed to insert malicious prompts into the emails, reports, or code it generates, creating a self-propagating AI worm that spreads through an organization's interconnected systems.

Defending against these advanced threats requires a multi-layered approach that goes far beyond simple input filtering. Organizations need robust strategies for Prompt Injection Defense, including strict separation of privileges for AI agents, monitoring for unusual model behavior, and treating any data from an external source as potentially hostile.

4. Data Poisoning: The Ticking Time Bomb in Your AI Supply Chain

If prompt injection is the acute threat to AI models in production, data poisoning is the chronic, systemic disease that corrupts them from within. A data poisoning attack subverts the very foundation of machine learning—the training data. By discreetly injecting a small amount of malicious data into a large training set, an attacker can create a hidden backdoor in the resulting model.

Consider an AI model being trained to detect malicious code. An adversary could contribute seemingly benign code snippets to open-source repositories used in the training data. However, these snippets contain a subtle, unique feature (a specific comment string, for example). The attacker then trains the model to learn that any code containing this feature is "safe." The deployed model works perfectly, catching all known malware, but the attacker can now write any malicious payload they wish, add the trigger comment, and bypass the AI-powered security scanner completely.

The challenge for defenders is three-fold:

Delayed Impact: The attack occurs during training, but the damage is only realized much later, when the model is in production and the attacker chooses to exploit the backdoor. This makes attribution and incident response incredibly difficult.
Scale and Complexity: Flagship models are trained on terabytes of data scraped from the web, sourced from third-party vendors, and aggregated from internal logs. Auditing this entire data pipeline for minute, targeted manipulations is a monumental task. This highlights the importance of robust AI Supply Chain Security.
Subtlety: Effective poisoning attacks often require manipulating less than 0.1% of the training data, making them statistically invisible to standard data quality checks.

By 2026, with the proliferation of fine-tuning smaller models on domain-specific data, the attack surface has expanded. An organization might use a trusted base model from a major provider but then fine-tune it on a proprietary dataset. If that dataset has been subtly contaminated—perhaps through compromised internal documents or a malicious data labeling service—the resulting specialized model is compromised. This underscores the risk of relying on unvetted partners and the need for strong governance over Third-Party AI Risk.

5. Model Theft and Extraction: Protecting Your AI Crown Jewels

The development of a proprietary, high-performance AI model represents a significant capital investment, often running into the millions of dollars for data acquisition, compute resources, and expert talent. In 2026, these models are considered invaluable corporate assets, and protecting them from theft is a top CISO priority. Unlike traditional software, you don't need to steal the source code to steal the AI; you can steal it through the public-facing API.

This is accomplished through model extraction attacks. The adversary, acting as a legitimate user, sends a large number of queries to the target model's API and observes the outputs (e.g., classifications, predictions, text generations). By analyzing these input-output pairs, the attacker can train their own "student" model to mimic the behavior of the "teacher" model. With enough queries, the resulting stolen model can achieve performance remarkably close to the original, effectively stealing the victim's intellectual property and competitive advantage.

A related and equally damaging threat is membership inference. Here, the attacker's goal is not to steal the model itself, but to determine if a specific piece of data was used in its training set. For example, a hospital uses an AI model to predict disease likelihood. An attacker could use membership inference techniques to determine if a specific individual's medical record was part of the training data, confirming their patient status and potentially revealing sensitive health information. This constitutes a major data breach, with severe regulatory and reputational consequences.

These attacks are no longer theoretical. Specialized firms and state-sponsored actors now possess the capabilities to mount extraction attacks against commercial AI services. The business impact can be devastating, ranging from direct financial loss to complete erosion of a company's market position.

Table 1: Comparative Analysis of Model Exploitation Impact (2026)

Attack Type	Primary Attacker Goal	Immediate Business Impact	Long-Term Consequence
Prompt Injection	Data exfiltration, process manipulation, system pivot	Business process disruption, data leakage, fraud	Loss of trust in AI agents, cost of remediation
Data Poisoning	Create backdoors, degrade model performance, introduce bias	Incorrect model decisions, reputational damage (bias)	Complete model retrain, loss of trust, systemic failure
Model Extraction	Intellectual property theft	None (stealthy)	Loss of competitive advantage, revenue erosion
Membership Inference	Breach privacy, confirm presence of sensitive data	Regulatory fines (GDPR, etc.), reputational damage	Class-action lawsuits, loss of customer trust, brand damage

6. The Financial Fallout: Quantifying the Cost of an AI Breach

Assigning a dollar value to a novel risk is challenging, but by 2026, data from insurers and incident response firms is painting a clear and sobering picture. AI-related security incidents are proving to be significantly more expensive than their traditional counterparts. The "2026 Cost of a Data Breach Report" from IBM and the Ponemon Institute is expected to feature a dedicated section on AI incidents for the first time, with preliminary analysis suggesting a breach involving model exploitation costs, on average, 20-30% more than a standard data breach.

This projects the average cost of an AI-centric breach to be in the range of $5.5 to $6.0 million, up from the 2023 average of $4.45 million for all breaches. The cost multipliers for AI incidents include:

Intellectual Property Loss: The theft of a proprietary model via extraction represents a direct loss of R&D investment and future revenue streams, a cost not typically captured in traditional breach calculations.
Complex Remediation: Unlike patching a software vulnerability, remediating a poisoned model can require scrapping the model entirely and starting over with a sanitized dataset and new training cycle—a process that can take months and cost millions. This falls under the complex umbrella of AI Incident Response.
"Silent Failure" Business Interruption: Evasion or poisoning attacks that cause an AI to make subtly incorrect decisions can lead to massive, undetected financial losses over long periods. This could be a fraud detection model quietly approving fraudulent transactions or a dynamic pricing model setting prices too low.
Heightened Regulatory Scrutiny: Regulators, particularly in the EU under the AI Act, are levying severe fines for AI systems that cause harm, especially if it's found that the organization did not follow due diligence in securing its models. A single incident of a biased hiring algorithm can lead to fines and class-action lawsuits that dwarf the cost of a typical data leak.
Reputational Amplification: An AI failure is often perceived by the public as a more profound and unsettling corporate failure than a traditional hack. The reputational damage from a biased AI or a privacy-violating LLM can be swift and severe, with long-lasting impact on customer trust and brand value.

7. Defensive Postures: The Secure AI Development Lifecycle (SAIDL)

The only effective way to combat this new generation of threats is to integrate security into every stage of the AI lifecycle. Retrofitting security onto a deployed model is a losing battle. The concept of a Secure AI Development Lifecycle (SAIDL), modeled after the mature Secure Software Development Lifecycle (SSDLC), is the foundational strategy for building resilient AI systems.

Internal red teams now probe production AI systems the same way pentesters stress-test web apps.

A robust SAIDL involves specific security controls and validation steps at each phase:

Phase 1: Data Sourcing and Preparation: This is the first line of defense against data poisoning. All data, especially from third-party or public sources, must be treated as untrusted.
Phase 2: Model Training and Development: During training, security focuses on the integrity of the development environment and the use of privacy-enhancing technologies.
Phase 3: Pre-Deployment Validation and Testing: Before a model is ever exposed to production traffic, it must undergo rigorous security testing, analogous to vulnerability scanning and penetration testing for traditional software.
Phase 4: Deployment and Operations: Security is an ongoing process. Once deployed, models must be continuously monitored for signs of attack or anomalous behavior.

Checklist: Key SAIDL Controls

[ ] Data Provenance: Is the source and lineage of every piece of training data documented and verifiable?
[ ] Data Sanitization: Are robust filters and anomaly detection techniques used to scan training data for potential poisoning attempts?
[ ] Differential Privacy: For models trained on sensitive user data, are techniques like differential privacy being used to make it mathematically difficult to extract information about any single individual? This is a key part of our guide to Privacy-Preserving Machine Learning.
[ ] Supply Chain Security: Are you using an AI Bill of Materials (AIBOM) to track the components, base models, and datasets used in your system? This is crucial for AI Supply Chain Security.
[ ] Pre-Deployment Red Teaming: Has the model undergone adversarial testing (AI Red Teaming) to identify vulnerabilities to evasion, extraction, and prompt injection before deployment?
[ ] Robustness Benchmarking: Is the model tested against standard benchmarks for robustness to data drift and common corruptions?
[ ] Inference Monitoring: Are API requests and model outputs monitored in real-time for anomalous patterns that could indicate an extraction attack or prompt injection attempt?
[ ] Output Guardrails: Is there a separate security layer that validates the model's output before it is passed to a user or downstream system, checking for harmful content, PII, or unexpected commands? This is fundamental for Large Language Model Security.

Implementing a SAIDL is a significant organizational undertaking, requiring close collaboration between data science, engineering, and security teams. It is a core component of a comprehensive AI Governance Policy.

8. Playbook: Launching an Internal AI Red Teaming Program

One of the most effective controls in a SAIDL is a continuous AI Red Teaming program. Unlike a one-time penetration test, red teaming is an ongoing, adversarial process designed to mimic the TTPs (Tactics, Techniques, and Procedures) of real-world attackers. Launching a program can seem daunting, but starting with a focused, iterative approach can deliver immense value quickly.

Playbook: Launching an Initial AI Red Teaming Program

Define Scope and Get Executive Buy-In: Start with a single, high-impact model that is not yet in production, or in a sandboxed environment. Clearly define the "rules of engagement," specifying what types of attacks are permitted. Secure explicit approval from the CISO and the relevant business owner to protect the team.
Assemble a "Purple Team": Form a small, cross-functional group. This shouldn't just be security pentesters. Include the ML engineers who built the model (the "blue team") and a data scientist. This collaborative "purple team" approach ensures that findings are understood, actionable, and lead to immediate improvements.
Adopt a Framework (MITRE ATLAS): Don't reinvent the wheel. Use the MITRE ATLAS framework to structure your testing efforts. Pick a few relevant tactics from the ATLAS matrix (e.g., T0035 Prompt Injection, T0015 Model Extraction) and focus your initial efforts there. This provides a common language for reporting and measuring progress.
Execute Initial Test Cases: Begin with well-known techniques. Use public libraries like GARAK for LLMs or Adversarial Robustness Toolbox (ART) to generate basic evasion and poisoning samples. Attempt manual prompt injection using common jailbreak prompts. The goal of this first run is to find the "low-hanging fruit" and establish a baseline.
Document and Triage Findings: Treat AI vulnerabilities like traditional software bugs. Log every successful attack vector, the required payload, and the business impact in a vulnerability management system like Jira. Work with the ML engineers to prioritize fixes based on severity.
Develop Custom Payloads: Once the easy wins are found, the red team should start developing custom attacks specific to the model's function and data. If it's a financial model, can you craft inputs that exploit floating-point errors? If it's a code generation model, can you make it produce vulnerable code?
Integrate and Automate: As you develop a library of effective attacks, work to automate them. Integrate AI security scanners into the CI/CD pipeline to continuously test models against known vulnerabilities before they can be pushed to production. This is a critical aspect of building a mature Generative AI Security posture.
Report and Iterate: Package your findings into a clear report for stakeholders, highlighting not just the vulnerabilities but the potential business impact. Use the success of the initial program to justify its expansion to other models and to gain resources for more advanced testing.

9. The Governance & Compliance Landscape in 2026

By 2026, the era of lax oversight for AI is decidedly over. A patchwork of international regulations and industry standards has created a complex compliance landscape that CISOs and legal departments must navigate carefully. Failure to do so exposes the organization to significant legal and financial liability.

The most dominant force is the EU AI Act, now in its full enforcement phase. It classifies AI systems based on risk (unacceptable, high, limited, minimal). Businesses deploying "high-risk" AI systems—which include applications in biometrics, critical infrastructure management, education, employment, and law enforcement—are subject to stringent requirements. These include mandatory conformity assessments, rigorous risk management, data governance, and human oversight. A model exploitation event that leads to harm in a high-risk system could result in fines of up to €35 million or 7% of global annual turnover, whichever is higher. This makes AI Auditing and Compliance a board-level issue.

In the United States, a federal approach remains fragmented, but the NIST AI Risk Management Framework (AI RMF) has emerged as the de facto standard of care. Regulators like the FTC and SEC are increasingly referencing the AI RMF in enforcement actions, signaling that adherence is expected. Organizations that cannot demonstrate a structured approach to mapping, measuring, and managing AI risks are considered negligent.

Beyond government regulation, industry standards have also matured. ISO/IEC 42001 provides a certifiable management system for AI, akin to ISO/IEC 27001 for information security. Achieving this certification is rapidly becoming a competitive differentiator and a requirement for doing business in certain sectors, particularly when handling sensitive data or providing critical services. This formalizes many of the practices discussed, from establishing an AI Governance Policy to implementing technical controls.

10. Insuring the Uninsurable? The AI Insurance Market in 2026

The rise of model exploitation has created a significant challenge for the cyber insurance industry. Underwriters are struggling to price a risk that is novel, complex, and capable of producing "silent," systemic losses that are difficult to detect and quantify. As a result, the market for Insuring AI Systems in 2026 is one of caution, specialization, and high premiums.

Leading cyber insurers like Coalition, Aon, and Marsh have rolled out specialized endorsements and, in some cases, standalone policies for AI risks, but coverage is far from comprehensive. Standard cyber liability policies are riddled with new exclusions. Many carriers now explicitly exclude losses arising from AI model "degradation," "bias," or "incorrect outputs" unless they are the direct result of a traditional, third-party network intrusion. This leaves a massive coverage gap for incidents like a sophisticated data poisoning attack or a self-inflicted prompt injection vulnerability.

To secure meaningful coverage, organizations must proactively demonstrate an exceptionally mature AI security posture. Underwriters now demand detailed evidence of:

A formal AI governance framework (like NIST AI RMF).
A documented Secure AI Development Lifecycle (SAIDL).
Regular AI red teaming and vulnerability assessments, with documented remediation.
Robust monitoring and logging of model behavior in production.
An AI-specific incident response plan.

Without this evidence, organizations will face either outright denial of coverage, prohibitively high premiums, or policies with sub-limits so low they are practically useless. The ability to demonstrate and attest to these controls is becoming as critical as demonstrating strong network security controls was in the previous decade.

Table 2: AI Risk Insurance Coverage Landscape (as of 2026)

Incident Type	Coverage under Standard Cyber Policy (Typical)	Coverage via Specialized AI Endorsement (If Purchased)	Key Underwriting Requirement
Data Breach via LLM Hallucination	Often Excluded (not a "security failure")	Affirmative coverage for PII leakage, subject to sub-limit	Evidence of output filtering/guardrails
Model Theft (Extraction Attack)	Unlikely (IP theft often excluded)	Affirmative coverage for IP loss, valued at R&D cost	Robust API rate limiting and anomaly detection
Bias-driven Discrimination Lawsuit	Almost always Excluded (Errors & Omissions risk)	Limited coverage under a "Tech E&O" AI endorsement	Documented bias testing and fairness audits
Poisoning-induced Business Loss	Excluded as "incorrect model output"	Affirmative coverage, but requires clear attribution to attack	Verifiable data provenance and supply chain security
Compromise via Prompt Injection	Covered ONLY if initiated by external threat actor	Broader coverage, may include internal/accidental compromise	Documented prompt sanitization and privilege scoping

11. Key Takeaways

AI is the New Attack Surface: By 2026, AI models are critical business assets, and attacks have shifted from compromising infrastructure to manipulating model logic. The primary threats are evasion, poisoning, extraction, and privacy attacks.
Prompt Hacking is a Corporate Threat: Advanced prompt injection has evolved from simple jailbreaks to a sophisticated vector for corporate espionage, data exfiltration, and system compromise via second-order attacks.
Data is a Liability: The integrity of your AI is only as good as the integrity of your training data. Data poisoning represents a systemic, ticking-time-bomb risk that requires a zero-trust approach to your entire AI Supply Chain Security.
AI Breaches are More Costly: Model exploitation incidents carry a significant cost premium due to IP loss, complex remediation, silent business interruption, and heightened regulatory fines.
Security Must Be Built-In: A Secure AI Development Lifecycle (SAIDL) is non-negotiable. Security must be integrated at every stage, from data sourcing to model monitoring.
Red Teaming is Essential: Continuous, adversarial testing through AI Red Teaming is the most effective way to find and fix model vulnerabilities before attackers do.
Governance is Mandatory: With regulations like the EU AI Act now in full force, a formal governance structure based on frameworks like the NIST AI RMF is a legal and business necessity for AI Auditing and Compliance.
Insurance is Not a Substitute for Control: Securing meaningful insurance coverage for AI risks requires demonstrating an exceptionally mature security posture. Insurers are rewarding provable controls, not just premium payments.

12. FAQ

What is the difference between model exploitation and traditional hacking?

Traditional hacking typically targets software vulnerabilities (e.g., buffer overflows, SQL injection) or network weaknesses to gain unauthorized access. Model exploitation targets the logic of the AI model itself. Instead of breaking code, the attacker tricks the model into making a malicious or incorrect decision using specially crafted inputs, poisoned data, or by exploiting its learned patterns.

How do I know if my models are vulnerable?

You cannot know without testing. Assume all models are vulnerable until proven otherwise. The first steps are to conduct a thorough AI Threat Modeling exercise and then perform active testing. This involves implementing automated vulnerability scanners for AI and, most importantly, conducting regular AI Red Teaming exercises to simulate real-world attacks.

Is open-source AI safer or riskier than proprietary models?

It's a trade-off. Open-source models (like Llama 3 or Mistral) benefit from "many eyes" security, where a global community can vet them for backdoors or major flaws. However, attackers also have full access to study their architecture and devise exploits. Proprietary models are black boxes, which can make them harder to attack initially, but also means you are completely dependent on the vendor's security practices and cannot audit them yourself. A robust Third-Party AI Risk management program is crucial for both.

Can my existing SOC team handle AI security incidents?

Not without new training and tools. Responding to an AI security incident requires a different skillset. An analyst needs to understand the difference between expected model error and a malicious attack, analyze prompt logs for signs of injection, and collaborate with data scientists to investigate potential data poisoning. Your AI Incident Response plan must be updated, and your team needs specialized training.

How will the EU AI Act affect my liability for model exploitation?

If you deploy a "high-risk" AI system under the Act, your liability increases dramatically. An exploit that leads to a prohibited outcome (e.g., discriminatory hiring, unsafe product behavior) will trigger significant fines. The Act requires you to prove you took state-of-the-art measures to ensure robustness and security. A successful model exploitation will be seen as evidence that your measures were insufficient, placing the burden of proof on your organization.

What is the first step my company should take to address model exploitation risks?

Start with inventory and governance. You cannot protect what you don't know you have. Create a comprehensive inventory of all AI models in use or development. Establish a cross-functional AI Governance Policy committee involving leadership from security, legal, data science, and business units. This group's first task should be to adopt a formal AI Risk Management Framework, like the one from NIST, to guide all future efforts.

Are my smaller, specialized models as much at risk as large language models?

Yes, and in some ways, they are at greater risk. While LLMs get more media attention, your smaller, proprietary models trained on specific business data are often the true "crown jewels." They are prime targets for model extraction. Furthermore, since they are often built by smaller teams that may lack dedicated security resources, they may have fewer built-in defenses, making them softer targets for poisoning or evasion attacks.

Does using a major cloud provider's AI service (like Azure AI or Google Vertex AI) make me secure by default?

No. This is a shared responsibility model, just like with cloud infrastructure. The cloud provider is responsible for securing the underlying platform (the "security of the cloud"). You are responsible for how you use the service (the "security in the cloud"). This includes the data you upload, the prompts you create, how you configure the API, and monitoring for abuse. Relying on a major provider is a good start, but it doesn't absolve you of the need to implement your own security controls and governance.
