Artificial Intelligence / LLM Penetration Testing at COE Security
At COE Security, our Artificial Intelligence (AI) and Large Language Model (LLM) Penetration Testing service focuses on identifying vulnerabilities and risks within AI models and systems, including LLMs like GPT, BERT, and other AI-driven technologies. As AI systems and LLMs become more integrated into business processes, they pose unique security challenges. The complex nature of AI models, along with their reliance on vast datasets and intricate algorithms, makes them susceptible to a variety of attacks ranging from adversarial inputs and data poisoning to model inversion and privacy risks.
Our penetration testing service for AI and LLMs simulates potential attack vectors to uncover weaknesses and flaws in your AI models, APIs, training data, and deployment environments. This proactive approach allows you to assess the robustness of your AI systems, ensuring that they are secure, reliable, and resistant to manipulation or misuse by malicious actors.
Our Approach
Define scope and AI components: Identify LLMs, APIs, data pipelines, and integrations subject to testing across training and inference layers.
Enumerate attack surfaces and inputs: Map user inputs, plugins, prompts, and APIs used to interface with the AI system or model.
Evaluate prompt injection and manipulation: Test for jailbreaks, prompt leaking, role confusion, and output manipulation through crafted input payloads.
Test model output filtering and alignment: Validate whether safety controls prevent toxic, biased, or harmful outputs in adversarial input conditions.
Assess training data exposure risks: Probe for unintended memorization, sensitive data leakage, and training data inversion through generative outputs.
Probe for plugin and API abuse: Simulate malicious use or chaining of third-party plugins, APIs, or external functions for unauthorized access.
Inspect authentication and session control: Evaluate token handling, session isolation, and misuse of identity in AI-integrated user workflows.
Analyze model behavior under adversarial input: Submit edge-case or malicious inputs to test robustness, hallucination frequency, and error handling logic.
Review logging, telemetry, and observability: Check for secure handling of logs, prompt records, and telemetry to avoid unintended data disclosures.
Report findings and provide recommendations: Deliver actionable findings, impact analysis, and tailored mitigation strategies aligned with AI risk frameworks.

Five areas of AI & LLM Penetration Testing
Internet of Things (IoT)
Cloud Security / Penetration Testing
Cloud security is a vital discipline focused on safeguarding data, applications, and infrastructure within cloud environments. It encompasses a broad range of practices and technologies designed to protect cloud-based systems from internal and external threats. This includes securing data storage, managing access controls, monitoring for unauthorized activities, and ensuring compliance with industry standards. Cloud security assessments involve evaluating the configuration of cloud services, identifying misconfigurations, and testing identity and access management (IAM) policies to detect potential weaknesses. By implementing robust cloud security measures, organizations can maintain the confidentiality, integrity, and availability of their cloud assets, ensuring secure and resilient operations across public, private, and hybrid cloud infrastructures.
