AI in Healthcare: An Asset or Attack Surface?

By Russell Teague, Chief Information Security Officer, Fortified Health Security

Artificial intelligence (AI) has rapidly moved from experimental innovation to mainstream enterprise adoption. From predictive analytics in finance to generative design in manufacturing, AI has become embedded in the daily workflows of organizations across industries. What was once a research pursuit is now a business necessity, reshaping competitive advantage and operational efficiency. But with this acceleration comes an unavoidable paradox: AI is simultaneously an asset that drives transformation and an attack surface that introduces new vulnerabilities. The organizations best positioned to succeed are not those that adopt AI fastest, but those that adopt it with rigor, resilience, and a deep understanding of its risks.

AI’s Transformational Role in Healthcare

Few industries stand to benefit from AI as profoundly as the healthcare sector. AI-driven diagnostic models can detect disease earlier than human specialists. Machine learning algorithms can optimize hospital staffing, predict patient readmissions, and accelerate drug discovery. Even patient engagement is evolving, with chatbots and virtual assistants expanding the clinical reach. Together, these innovations promise not only efficiency but also something far more critical: improved patient safety and better outcomes. AI, properly integrated, can reduce errors, enhance precision medicine, and strengthen the continuum of care from diagnosis to recovery. In short, AI has the power to make healthcare safer.

The Disruption Problem: When Innovation Outpaces Safeguards

History teaches us that every disruptive innovation carries unintended consequences. The same algorithms that can detect cancer can also be manipulated by adversarial inputs. Tools designed to accelerate care delivery can expose sensitive patient data if improperly secured. Healthcare is uniquely vulnerable because of its dual dependencies: life-critical operations and regulated patient data. When disruption outpaces governance—as it has with the rapid infusion of AI into enterprise products—the consequences are amplified, especially so in the healthcare sector.

The recent Microsoft CoPilot bypass is a prime example. Attackers successfully combined prompt injection techniques with phishing lures to manipulate an AI-powered assistant into leaking sensitive information and circumventing its intended security controls. This incident highlights a harsh reality: AI-embedded workflows are not theoretical targets—they are live attack surfaces that threat actors are actively testing right now.

Why Healthcare Faces Greater Risk

Hospitals and health systems that adopt tools like CoPilot face risks that differ from those of traditional enterprises. AI assistants integrated into electronic health records (EHRs) or patient communication platforms have direct access to protected health information (PHI). A compromised workflow could expose medical histories, alter care instructions, or misroute lab results. Unlike retail or finance, where a breach might “only”

involve financial loss, in healthcare, it can directly endanger patient safety and trust. That’s why the stakes are existential: breaches don’t just damage reputations—they can cost lives.

Healthcare-Specific Risks: When AI Meets Clinical Reality

The environments in which AI systems operate leave healthcare uniquely exposed. Clinical workflows are high stakes, regulated, and often run on fragile, legacy infrastructures. Embedding AI into these workflows introduces three categories of risk:

1. Clinical Safety Risks – Adversarial manipulation of diagnostic algorithms or clinical decision support tools could lead to delayed diagnoses, incorrect treatment recommendations, or misprioritized patient cases. In environments where seconds matter, manipulated outputs could directly harm patients.

2. Data Integrity Risks – AI tools increasingly sit on top of electronic health records and imaging systems, which makes them attractive targets for data poisoning. If an attacker corrupts training data or input pipelines, it can result in systematically skewed outputs that may be hard to detect immediately.

3. Operational Continuity Risks – Many providers are integrating AI into scheduling, patient communication, and supply chain logistics. A disruption in these AI-powered functions—whether caused by exploitation or simple model failure—can ripple into canceled appointments, delayed surgeries, and compromised patient trust.

The NIST AI Risk Management Framework (AI RMF) emphasizes governance, mapping, and continuous monitoring as essential for mitigating these categories of risk. For healthcare leaders, applying this framework entails conducting impact assessments before deployment, enforcing stringent data quality standards, and establishing monitoring mechanisms that promptly detect anomalous AI behavior. The aim isn’t to slow adoption but to ensure that the safety, integrity, and reliability of patient care remain uncompromised.

Broader Enterprise Takeaway

The lesson extends beyond healthcare. Any enterprise embedding AI into its workflows—whether through copilots, AI-enabled productivity suites, or customer-facing assistants—must accept that the attack surface has shifted. Adversaries are already experimenting with ways to exploit AI decision-making, manipulate outputs, and weaponize automation. The same capabilities that make AI powerful—autonomy, scale, adaptability—are what make it dangerous when misused. Enterprises that continue to treat AI security as an afterthought will soon discover that their workflows have become their weakest link.

Recommendations: Challenging the Status Quo

The challenge is not to slow AI adoption, but to match innovation with safeguards. Cybersecurity leaders must step beyond traditional controls and adopt AI-specific security postures. Among the most urgent steps:

● Targeted AI Security Reviews: Evaluate AI systems as you would critical infrastructure. Test them, simulate adversarial prompts, and continuously validate safeguards against evolving attack techniques.

● Granular Access Controls: Apply least-privilege principles to AI assistants. If an AI system doesn’t need access to sensitive datasets, don’t grant it. Over-entitlement in AI workflows magnifies risk.

● Training for AI-Generated Content: Update phishing awareness programs to include AI-crafted messages. Users must learn to recognize not only poorly written scams, but also well-polished, AI-enhanced deceptions.

● Vendor Accountability: Push technology providers beyond “security by design” slogans. Demand transparency in training data and testing methodologies designed for AI features.

● Governance Frameworks: Build AI into enterprise risk management, compliance, and security governance. Treat it as a first-class citizen of your cyber risk program, not a bolt-on.

The Burden on Cybersecurity Experts

The responsibility placed on cybersecurity experts is pivotal. Our responsibility is not only to detect and respond, but to anticipate and adapt. We must challenge the rush-to-market mentality that too often prioritizes features over safety, and advocate for frameworks that protect patients, customers, and enterprises from unintended consequences. Most of all, it’s crucial that we accept the burden of leadership: ensuring that as AI reshapes society, it does so safely and responsibly. This burden is heavy, but it is non-negotiable.

Matching Innovation with Safeguards

AI is both an asset and an attack surface. Its potential to revolutionize healthcare and other industries is undeniable, but so too are its risks. The CoPilot bypass is not an isolated event—it is a warning shot. If innovation is to improve lives truly, it must incorporate AI-specific safeguards, rigorous oversight, and relentless vigilance from cybersecurity leaders. The future of AI will not be defined solely by how advanced it becomes, but by how responsibly we secure it.
