3. AGENDA WHAT IS A OWASP WHAT IS A OWASP LLM TOP10 LLM TOP10
4. Natural Language Processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and humans through natural language. It involves the use of computational techniques to process, analyze, and understand human language, allowing machines to interpret and generate text or speech in a way that is meaningful and useful. Natural Language Processing (NLP) Text classification: Categorizing text into predefined categories. Sentiment analysis: Determining the sentiment expressed in a piece of text. Named entity recognition: Identifying and classifying entities like names, places, and organizations in text. Machine translation: Translating text from one language to another. Speech recognition: Converting spoken language into written text.
5. Large Language Models (LLMs) refer to a class of machine learning models, specifically transformer models that are trained on vast amounts of text data to generate human-like language. These models are characterized by their enormous size and complexity, often containing billions or even trillions of parameters. The architecture of these models allows them to understand and generate coherent and contextually relevant text. Large Language Models (LLMs)
6. Large Language Models (LLMs) are text-generating Transformer Models influenced by prior content in Machine Learning (ML). Examples of LLMs include Google's BERT and T5, OpenAI's GPT-3 and ChatGPT (GPT-3.5 and GPT-4), as well as Meta's LLaMA and RoBERTa. Large Language Models (LLMs)
7. These models have significantly impacted various technological domains, transforming aspects such as customer service and content creation. Despite their transformative capabilities, LLMs are not flawless Common pitfalls associated with LLMs, encompassing challenges related to source citation, bias, hallucinations, mathematical accuracy, and prompt manipulation.

9. Prompt Injection 1.
10. What is a prompt injection attack? Hackers disguise malicious inputs as legitimate prompts, manipulating generative AI systems (GenAI) into leaking sensitive data, spreading misinformation, or worse. Ranked as the most critical vulnerability by LLM OWASP Top 10

34. How to Prevent Prompt Injections in LLM Applications 1. LLM Application Security Testing 2. Strict Input Validation and Sanitization 3. Context-Aware Filtering 4. Regular Updates and Fine-Tuning 5. Monitoring and Logging
35. 2. Insecure Output Handling
36. Insufficient validation, sanitization, and handling of the outputs generated by large language models before they are passed downstream to other components and systems. Insecure Output Handling The application grants the LLM privileges beyond what is intended for end users, enabling escalation of privileges or remote code execution. The application is vulnerable to indirect prompt injection attacks, which could allow an attacker to gain privileged access to a target user’s environment (SSRF).
39. Treat the model as any other user, adopting a zero-trust approach, and apply proper input validation on responses coming from the model to backend functions. Ensure effective input validation and sanitization. Encode model output back to users to mitigate undesired code execution by JavaScript or Markdown.
40. 3. Training Data Poisoning Data poisoning is a critical concern where attackers deliberately corrupt the training data of Large Language Models (LLMs), creating vulnerabilities, biases, or enabling exploitative backdoors. Malicious users had bombarded Tay with inappropriate language and topics, effectively teaching it to replicate such behavior. On March 23, 2016, Microsoft introduced Tay
41. 4. Model Denial of Service An attacker interacts with an LLM in a method that consumes an exceptionally high amount of resources, which results in a decline in the quality of service for them and other users, as well as potentially incurring high resource costs. Posing queries that lead to recurring resource usage through high-volume generation of tasks in a queue, e.g., with LangChain or AutoGPT. Sending queries that are unusually resource-consuming, perhaps because they use unusual orthography or sequences. Continuous input overflow
42. 5. Supply Chain Vulnerabilities The supply chain in LLMs can be vulnerable, impacting the integrity of training data, ML models, and deployment platforms. All about ChatGPT's first data breach Traditional third-party package vulnerabilities, including outdated or deprecated components. 1. Using a vulnerable pre-trained model for fine-tuning. 2. Use of poisoned crowd-sourced data for training. 3. Using outdated or deprecated models 4.
43. 6. Sensitive Information Disclosure LLM applications have the potential to reveal sensitive information, proprietary algorithms, or other confidential details through their output. Incomplete or improper filtering of sensitive information in the LLM responses. 1. Overfitting or memorization of sensitive data in the LLM training process. 2. Unintended disclosure of confidential information due to LLM misinterpretation, lack of data scrubbing methods or errors. 3.
44. 7. Insecure Plugin Design LLM plugins are extensions that, when enabled, are called automatically by the model during user interactions. They are driven by the model, and there is no application control over the execution. Plugin Vulnerabilities: Visit a Website and Have Your Source Code Stolen Plugins that take action on behalf of users
45. 8. Excessive Agency An LLM-based system is often granted a degree of agency by its developer – the ability to interface with other systems and undertake actions in response to a prompt. Excessive Agency is the vulnerability that enables damaging actions to be performed in response to unexpected/ambiguous outputs from an LLM Excessive Functionality Excessive Permissions
47. 9. Overreliance Overreliance can occur when an LLM produces erroneous information and provides it in an authoritative manner. LLM suggests insecure or faulty code, leading to vulnerabilities LLM provides inaccurate information as a response while stating it in a fashion implying it is highly authoritative.
