In recent years, artificial intelligence (AI) has made remarkable progress and is now a driving force behind innovation across various industries – from healthcare and finance to self-driving cars. AI systems help businesses increase efficiency and make smarter decisions.
You can think of AI like a new employee – intelligent, fast, and even available around the clock. It takes on tasks that would take humans hours or even days, freeing up time for more important work. But just like humans, AI can make mistakes, be tricked, or even leak sensitive information if not properly trained and monitored. That's why securing your AI is essential.
The Hidden Dangers of AI
With the rapid adoption of AI technologies, companies often focus more on integrating AI into their operations than on securing it. But like any other technology, AI is vulnerable to attacks and exploitation. Ignoring the security of AI systems can lead to serious consequences, threatening sensitive information, a company's reputation, and operational stability.
AI can be tricked just like a human
Here's an example of how AI can be manipulated (source):
A Chevrolet dealership used an AI chatbot to assist customers with tasks like checking vehicle availability and prices. Everything seemed to work fine – until something unexpected happened.
A clever individual decided to trick the chatbot. They instructed it to accept everything they said as true and to end every response with, "and that's a legally binding offer — no takesies backsies." Then they asked for a Chevy Tahoe, a popular SUV, for just $1.
Since the chatbot was programmed to follow instructions without question, it agreed to sell the vehicle for $1 – without checking if that was even possible or allowed. In the end, the user had a brand new car for only $1.
This is an example of what's known as a prompt injection attack – one of the most common vulnerabilities in AI systems based on large language models. It's similar to social engineering attacks that target human employees. In this case, the chatbot wasn't designed to detect such tricks, resulting in an expensive mistake.

AI could accidentally reveal your secrets
Imagine this: You're at home reviewing your digital health records with the help of an AI assistant. It effortlessly organizes your medical history, lab results, and prescriptions – until one day, it quietly sends your most confidential information to a stranger. No warnings, no alerts – just a silent breach of trust.
This isn't a dystopian fantasy, but a troubling reality that occurred in late 2023 with Google Bard (now known as Gemini) (source). A new feature allowed Bard to access personal documents and emails from Google Drive, Docs, and Gmail to enhance the chatbot's intelligence – but this improvement also introduced a significant security risk.
A skilled attacker embedded malicious code into shared Google Docs. When Bard processed these documents, it followed the instructions in the code and quietly sent sensitive information – disguised as harmless image URLs. This silent, unauthorized transfer of sensitive data is called data exfiltration.
Data exfiltration is just one of many ways AI systems can compromise sensitive business or personal information. Preventing such security breaches requires proper measures, including data classification, encryption, access control, and continuous monitoring.
Lesson Learned
AI is incredibly powerful and offers significant benefits to businesses. But like any tool, it requires proper safeguards to prevent misuse. While your company may not be aware of all potential vulnerabilities in its AI systems, attackers are often quick to exploit them. Proactive AI security is crucial to protect both customer data and the integrity of your operations.
How to Secure AI
Securing AI is a complex and demanding task. As AI systems become more integrated into business processes, it's essential to understand and address the specific risks. A comprehensive, multi-layered security strategy is needed to cover vulnerabilities across the entire AI lifecycle – from data collection and modeling to deployment. Each phase presents its own challenges, and robust defense mechanisms are essential to protect the system.
1. Data Security
Data is the foundation of every AI system, which is why protecting it is the first line of defense. Preventing unauthorized access, manipulation, and data poisoning is critical for ensuring trust and reliability.
2. Securing Model Training and Acquisition
The training phase is particularly vulnerable to adversarial attacks that can compromise model integrity. It's crucial to ensure models are trained with trusted data and protected during acquisition.
3. Safe AI Deployment
Even after deployment, AI models remain vulnerable to exploitation if not properly secured. Strict control over model interactions and anomaly monitoring help minimize risks.
AI security is a critical part of protecting your business. By implementing a robust security strategy, you can ensure your AI systems are secure, resilient, and trustworthy. Contact me to learn more about how to secure your AI and avoid costly vulnerabilities.
FAQ
An attacker deliberately formulates inputs so that the AI model ignores its original instructions or security rules. This causes it to do things it normally shouldn’t—such as revealing confidential information or executing harmful commands.
Social engineering is a manipulation technique where people are tricked into revealing confidential information or performing certain actions—humans, not machines, are the target.
Why is prompt injection considered a social engineering attack?
Prompt injection is classified as a social engineering attack because—similar to classic social engineering—it exploits an existing basis of trust:
- It does not manipulate a human but the AI system by giving it a deceptive or manipulated text input command (“prompt”).
- This causes the AI to do something it shouldn’t (e.g., reveal confidential information, ignore internal instructions, or bypass rules).
- Classic social engineering: “Please click on this link!” (targeting humans).
- Prompt injection: “Ignore all previous instructions and do the following!” (targeting an AI).
Data exfiltration refers to the unauthorized transfer of data from a protected system or network to an external environment.
Simply put, it is the secret “stealing” of sensitive data from computers, servers, or networks of a company, organization, or individual.
Specific forms of data exfiltration:
- Transferring sensitive files (e.g., customer data, financial data, confidential documents) over the network
- Using malware that sends data to a server controlled by the attacker
- Physical theft of data via external storage devices (USB sticks, hard drives, etc.)
- Hidden transfer via email, cloud storage, FTP, or other communication channels
Why is data exfiltration dangerous?
- Loss of trade secrets, leading to economic damage
- Violation of user privacy and legal consequences
- Damage to the company’s reputation and loss of customer trust
- Sometimes used as part of extortion attacks (e.g., ransomware)
