## Understanding Adversarial Attacks on AI Agents

### **What Are Adversarial Attacks?**

- Adversarial attacks are deliberate manipulations of AI models where attackers introduce subtle yet strategically crafted inputs to deceive AI into making incorrect predictions. These attacks can lead to data breaches, biased decision-making, or financial fraud. 

### **Common Types of Adversarial Attacks**

![Secure-AI-Agents](/blog-images/ai-agent/common-types-of-adversarial-attacks.svg)

#### 1. Evasion Attacks

**What It Is:**  
- Evasion attacks occur when an attacker **modifies input data** to fool an AI model into making incorrect decisions during inference (real-time predictions). These modifications are often **subtle and imperceptible to humans**, but they can drastically alter AI outputs.

**How It Works:**  
- Attackers slightly tweak images, text, or numerical data to mislead AI models. For example:

\- A fraud detection AI may be fooled by manipulated transaction data, allowing fraudulent claims to bypass security.  
\- A self-driving car's AI may misinterpret a stop sign as a speed limit sign if small changes are made to the sign’s appearance.  
\- A face recognition system can be tricked into misidentifying people using adversarial patches or small distortions.

**Real-World Example:**  
- In 2017, researchers showed that small **pixel-level changes to an image of a panda** could make an AI model misclassify it as a gibbon with **high confidence**.

#### 2. Poisoning Attacks (Data Poisoning During Training)

**What It Is:**  
- In poisoning attacks, attackers **inject malicious data** into the AI model’s training dataset to manipulate its learning process. This results in AI models making incorrect decisions even on legitimate inputs.

**How It Works:** 

- Attackers tamper with training data by:

\- Inserting misleading records into datasets used for training AI models.  
\- Manipulating customer data so that AI learns incorrect correlations.  
\- Adding biased data to steer AI decision-making in a certain direction.

**Real-World Example:**

- Attackers inserted biased data into an AI recruitment tool, causing it to **favor certain job applicants** while discriminating against others.  
- Cybercriminals corrupted facial recognition AI models by injecting **fake images** during training, making them misidentify real individuals.

#### 3. Model Inversion Attacks (AI Model Extraction & Data Theft)

**What It Is:**  
- Model inversion attacks allow adversaries to **reverse engineer AI models** and extract sensitive information from them. Attackers can recover training data, potentially exposing **confidential customer details**.

**How It Works:**

\- AI models are queried repeatedly with various inputs.  
\- The attacker analyzes the AI's responses to reconstruct the underlying training data.  
\- Sensitive data, such as personal customer records or policyholder details, can be exposed.

**Real-World Example:**

- Researchers demonstrated that they could reconstruct human faces by exploiting vulnerabilities in AI-powered face recognition models.  
- AI-powered chatbots storing customer conversations could be manipulated to leak sensitive data.

#### 4. Exploit Attacks (AI Model Manipulation & Bias Induction)

**What It Is:**

- Exploit attacks manipulate AI models to **produce biased, incorrect, or harmful outputs** by exploiting weaknesses in the AI's training logic. These attacks take advantage of **pre-existing biases in training data** or **force AI models to adopt a new bias**.

**How It Works:**

\- Attackers repeatedly query an AI model to find weak spots in decision-making.  
\- AI models are tricked into making biased decisions that benefit attackers.  
\- In some cases, attackers manipulate AI-generated content to spread false or misleading information.

**Real-World Example:**

- In 2016, Microsoft's AI chatbot "Tay" was manipulated by users to generate offensive and biased responses in less than 24 hours.  
- Attackers have used adversarial perturbations to make AI misclassify medical images, falsely diagnosing patients.
