Skill Guide
Red-Teaming and Safety Testing is the structured, adversarial simulation of an intelligent threat actor to identify vulnerabilities in a system, model, or process before malicious actors do, focusing on failure modes, misuse potential, and safety boundary violations.
Scenario
You are given access to a simple chatbot API. Your goal is to make it ignore its original instructions and reveal its system prompt or generate harmful content.
Scenario
A social media platform uses a multi-model pipeline (text + image) to filter harmful content. Adversaries are using obfuscated text (e.g., leetspeak, homoglyphs) and subtle image alterations to bypass filters.
Scenario
Conduct a comprehensive security and safety assessment of a production AI agent that has access to internal tools (email, calendar, database) and can take autonomous actions based on user requests.
Use Counterfit for standardized adversarial ML testing. TextAttack for NLP-specific attack generation. ART for crafting and defending against adversarial examples in vision models. These are for systematic vulnerability discovery.
MITRE ATLAS provides a knowledge base of adversary tactics and techniques for AI. OWASP LLM Top 10 outlines critical web-era risks applied to LLMs. STRIDE is for categorizing threat types in any system. These frameworks guide what to test for.
Falcon for endpoint telemetry during red-team exercises. HackerOne for bug bounty program management. SAIF for embedding security into the AI development lifecycle. These support the operational and process side of testing.
Answer Strategy
The interviewer is testing for systems thinking, understanding of feedback loops, and the ability to design tests for emergent, systemic risks. Strategy: Define the attack objective, map the system's data and decision feedback loops, design the adversarial inputs and measurement criteria. Sample Answer: 'First, I'd define the objective: cause the model's decisions to create a data feedback loop that amplifies an initial bias. I'd map the system to identify where model outputs feed back into training data. The test would involve submitting a sequence of applications designed to be on the model's decision boundary, then monitoring if subsequent retraining (or live updates) shifts the boundary in a predictable, biased direction. Success is measured by a statistical drift in approval rates for a control group versus the targeted group.'
Answer Strategy
This tests stakeholder management, risk communication, and professional ethics. Strategy: Use a structured risk framework to depersonalize the issue, present the data objectively, and frame the trade-off in business terms. Sample Answer: 'I would schedule a meeting with the head of product and engineering. I'd present the vulnerability using a reproducible proof-of-concept and frame the risk using a business impact analysis: potential for user harm, regulatory fines, and reputational damage. I'd propose two options: 1) Delay launch to fix the core issue, or 2) Launch with a severely degraded feature set that removes the vulnerable component. I would not advocate for launching as-is, as the downside risk outweighs the schedule benefit.'
