In 2016, Microsoft launched Tay, an AI chatbot designed to learn from conversations on Twitter. Within 16 hours, malicious users bombarded it with offensive content, poisoning its training data in real-time. Tay quickly began generating inappropriate messages, forcing Microsoft to shut it down. This incident exposed the dangers of unprotected AI systems—when bad data gets in, bad outputs come out.
Now, imagine the same scenario with Microsoft Copilot—but instead of tweets, it’s making business decisions. If an attacker manipulates its data sources, Copilot could generate misleading, biased, or even harmful insights, damaging enterprise operations.
Just like a chef following a recipe, AI systems rely on quality ingredients—clean, trustworthy data. But when model and data poisoning introduce tainted inputs, the AI serves up unreliable results. The dish might look the same, but one bite could make you want to vomit. Similarly, Copilot’s responses may appear correct on the surface, but poisoned data can lead to disastrous decisions
Model and Data Poisoning occurs when adversaries manipulate pre-training, fine-tuning, or embedding data to introduce vulnerabilities, backdoors, or biases. Unlike prompt injection, which tricks an AI into misbehaving during inference, poisoning attacks modify the AI before it even generates responses.
Three Main Types of Model and Data Poisoning:
Attackers introduce tainted data into large-scale AI models, affecting models or copilots before they are deployed.
Enterprise-specific fine-tuning can be compromised, leading to biased outputs or hidden triggers.
Malicious data is injected into vector databases or contextual sources connected to the model, causing Copilot to retrieve manipulated information.
Since Copilot relies on external and internal data sources, the risk of poisoning is significant—particularly if attackers gain access to datasets without proper verification.
Let’s explore how attackers can manipulate Microsoft Copilot’s connected data:
A malicious insider embeds hidden trigger phrases in enterprise documentation. Whenever Copilot encounters these phrases, it responds inaccurately based on the text in the document.
An attacker uploads falsified reports online. Copilot, referencing these reports that are publicly available, unknowingly spreads misinformation within enterprise responses.
If an attacker manipulates Copilot’s learning sources, incorrect or manipulated information can spread throughout your organization.
Bad training data can lead to biased or unethical AI behavior, resulting in violations of GDPR, SOC 2, HIPAA, and other industry regulations.
Tainted AI outputs can lead to bad business decisions, misinformation, and a loss of confidence in AI-assisted workflows.
Microsoft has implemented safeguards to prevent data poisoning, but limitations exist:
Microsoft attempts to verify training data, but external poisoning is still a risk.
Ethical guidelines help mitigate bias, but they don’t actively detect poisoned inputs.
Microsoft scans for inappropriate content, but covert poisoning attacks can slip through.
These protections help but cannot fully eliminate targeted poisoning attacks—especially for enterprise-specific deployments.
Instead of relying solely on Microsoft’s defenses, Opsin provides proactive security measures that prevent data poisoning across the AI lifecycle:
Opsin ensures Copilot’s data is verified, sanitized, and aligned with enterprise security policies, proactively detecting anomalies before they impact real users.
Opsin continuously monitors Copilot’s inputs and user behavior to identify external poisoning attempts and suspicious data manipulations.
By analyzing user actions within GenAI, Opsin detects suspicious behavior patterns, pinpointing data uploads or tampering attempts that could compromise Copilot’s responses.
Just as a restaurant can’t rely solely on following a recipe to ensure food safety, enterprises can’t rely only on Microsoft’s guardrails to protect Copilot. A chef uses quality control—checking ingredients, monitoring freshness, and verifying sources—to prevent food poisoning. Opsin does the same for AI security.
Opsin ensures that every piece of data Copilot connected to is safe—before it can ever impact your organization.
