Data poisoning is the silent AI killer

AI thrives on data. But what happens when that data is manipulated? That’s data poisoning, where bad actors corrupt training datasets to distort AI behavior.

The National Institute of Standards and Technology (NIST) has flagged real-world cases, like attackers slipping offensive language into chatbot training sets. The result? AI-powered customer service reps suddenly talking like internet trolls.

Two main types of data poisoning exist:

  • Targeted attacks: Precision strikes designed to alter specific AI outputs, like tweaking financial fraud detection models to let certain transactions slide.

  • Indiscriminate attacks: More chaotic, these degrade AI performance across the board, making models unreliable or outright useless.

The core issue? AI models don’t know good data from bad. They learn from whatever they’re fed. And if you’re not controlling that input, someone else might be.

Know your data or risk losing control

Would you trust a financial report without knowing its source? AI training data should be treated the same way. If you don’t know where your data comes from, who has access, and how it’s handled, you’re heading into trouble.

You can’t protect what you don’t understand. AI security starts with data visibility, tracking its origins, verifying its quality, and controlling who touches it.

Key safeguards include:

  • Provenance tracking: Knowing exactly where data originates and making sure it’s from trusted sources.

  • Strict access control: Limiting who can modify training datasets, preventing insiders from slipping in harmful changes.

  • Continuous monitoring: Real-time scanning for unusual data patterns that could indicate an attack.

Data pipelines matter

Not all data pipelines are created equal. The way you process and transform data can either expose you to data poisoning or help prevent it.

For years, companies used ETL (Extract, Transform, Load), meaning data was transformed before being stored. The problem? If you transform data too early, before you’ve verified its integrity, flaws get baked in. That’s like making business decisions based on unaudited reports.

Now, companies are shifting to ELT (Extract, Load, Transform). This means storing raw data first, then transforming it in a controlled environment like Snowflake. The benefit? More oversight, better security, and the ability to filter out bad data before it enters your AI models.

Dave Jenkins, VP of Product & Research at Iterate.ai, explains: “With ELT, you keep transformations centralized and under control. You don’t have different applications tweaking data independently, introducing security blind spots.”

Switching to ELT means fewer surprises, and in AI, surprises are rarely good.

AI security is business security

AI is expanding your company’s attack surface. If you’re not thinking about security, someone else is, attackers.

Your AI models are only as strong as the security protecting them. If your organization is already struggling with basic cybersecurity, like weak passwords, poor patching, and loose identity management, your AI systems are vulnerable by default.

A strong AI security strategy integrates with broader corporate security:

  • Patching & updates: AI infrastructure needs to be as up-to-date as your other systems.

  • Zero Trust access control: Never assume any user or application should have access unless explicitly verified.

  • Least privilege principle: Give employees access to only what they need. Nothing more.

Ignoring AI security is bad business. Data poisoning can impact revenue, trust, and even regulatory compliance. Get ahead of the problem, or be forced to react later.

Teaching AI to fight back

You don’t stop cyberattacks by hoping they won’t happen. You stop them by preparing for them. That’s where adversarial training comes in, teaching AI models to detect and resist attacks.

How adversarial training works:

  1. Expose the model to poisoned data: Train it to recognize patterns that indicate tampering.

  2. Develop response mechanisms: AI learns to flag suspicious inputs instead of blindly accepting them.

  3. Iterate and improve: Just like cybersecurity, AI defenses need continuous refinement.

Research is backing this up. In healthcare AI, adversarial training has been proposed as a defense against biased or manipulated data, which could have life-or-death consequences. Another study outlines a framework specifically for defending AI models against poisoning attacks.

“If AI is part of your business, adversarial training should be part of your AI strategy.”

Final thoughts

AI is the future, but the future isn’t foolproof. Data poisoning is a real and growing risk. If you’re integrating AI into your business, securing your models should be as much of a priority as building them.

AI that works well today can fail spectacularly tomorrow if it’s fed bad data. In securing your data pipelines, enforcing governance, and integrating adversarial training, you’re protecting your business.

Key executive takeaways

  • Secure your data: Ensure full visibility of your AI training data by knowing its origins, access rights, and transformation processes. Leaders should enforce strict data governance to prevent malicious manipulation.

  • Optimize data pipelines: Shift from traditional ETL to ELT architectures to centralize data transformations. This change improves oversight and reduces the risk of integrating compromised data into AI models.

  • Strengthen governance practices: Implement comprehensive audit trails, validation frameworks, and controlled testing environments. Clear policies around data access and modifications can reduce vulnerabilities.

  • Invest in adversarial training: Prepare your AI models to identify and resist data manipulation by integrating adversarial training techniques. This proactive approach bolsters resilience against emerging data poisoning threats.
