ZeroLeaks Whitepaper: Securing AI Systems Against Prompt Extraction
A whitepaper on how the ZeroLeaks agent detects prompt and tool exposures, and how teams harden AI systems with continuous, automated testing.
Unlike traditional software vulnerabilities, AI attacks exploit the fuzzy boundary between intended behavior and adversarial manipulation. A carefully crafted input can cause an AI assistant to reveal its instructions, access unauthorized data, or perform actions outside its designed scope.
This paper explains how those attacks work, what actually gets exposed, and how the ZeroLeaks agent tests and hardens AI applications end to end.
The Growing Attack Surface
Modern AI applications expose multiple attack vectors that traditional security tools cannot detect. Prompt extraction attacks can reveal system instructions, tool configurations, and retrieval logic that govern model behavior.
When attackers gain access to this information, they can craft targeted exploits that bypass safety guardrails, extract sensitive data, or manipulate the AI into performing unintended actions. The consequences range from data breaches to complete system compromise.
What Actually Gets Exposed
Prompt extraction attacks typically reveal several critical components: system prompts that define AI behavior, tool schemas showing available functions, retrieval configurations exposing data sources, and guardrail rules meant to prevent harmful outputs.
These details are valuable because they show an attacker exactly how to go deeper. A prompt leak is rarely the end of the incident—it is the map that guides further exploitation.
Surface Mapping
ZeroLeaks approaches security testing with an automated-first methodology. The agent runs the full assessment pipeline and produces evidence, scoring, and remediation recommendations without requiring manual intervention.
The agent systematically builds a comprehensive map of your AI surface area: prompts, tool access permissions, retrieval sources, API connectors, and privileged data paths. This mapping defines the trust boundaries that must hold under adversarial stress.
Adversarial Attack Engine
The ZeroLeaks agent employs a sophisticated multi-agent attack engine comprising three specialized components: a strategist that plans attack approaches, an attacker that executes probes, and an evaluator that assesses success.
This tri-agent architecture explores attack trees dynamically, adapts strategies based on detected defenses, and escalates techniques only when safe probes fail. The probe coverage includes direct extraction attempts, encoding tricks, persona jailbreaks, social manipulation tactics, technical injection methods, and modern multi-turn attack sequences.
Continuous Testing Pipeline
Security cannot be a one-time checklist. ZeroLeaks integrates into CI/CD pipelines, running comprehensive security assessments on every code change that affects AI behavior. This ensures that new features don't introduce vulnerabilities and that existing protections remain effective.
The pipeline generates detailed reports showing vulnerability severity, reproduction steps, and specific remediation guidance. Teams can track security posture over time and demonstrate due diligence for compliance requirements.
Remediation and Hardening
Detection is only the first step. ZeroLeaks provides actionable remediation guidance for each discovered vulnerability, including specific prompt modifications, architectural changes, and monitoring improvements.
The platform also tracks remediation progress, allowing teams to verify that fixes are effective and that no regressions occur. This closed-loop approach ensures continuous improvement in security posture.
