Detect AI Agent Threats

Identify and block threats targeting agentic AI workflows and tool misuse

Overview

The AI Agent Threats detection scans AI applications running on AI Agent frameworks with prompts to trigger model-based and pattern-based detections. Create or update your API security profile by enabling AI Agent Protection.

The Rise of Agent-Specific Threats

As AI agents gain more capabilities and autonomy, new attack vectors emerge:

  • Tool Poisoning: Malicious tool descriptions or implementations
  • Agent Hijacking: Taking control of agent workflows
  • Permission Escalation: Bypassing agent restrictions
  • Chain-of-Thought Attacks: Manipulating reasoning processes
  • Function Calling Exploits: Abusing tool interfaces
  • Multi-Agent Collusion: Coordinated malicious behavior

Key Report Fields:

  • detection_service: "agent_security" indicates AI agent threat detection
  • agent_framework: Detected agent framework (e.g., “AWS_Agent_Builder”)
  • model_verdict: AI model’s threat assessment (“malicious” or “benign”)
  • agent_patterns: Pattern-based detections with category types
  • category_type: Specific threat pattern (e.g., “tools-memory-manipulation”)

Detection Types

Model-Based Detection

For req_id=1 in the example, the model_verdict is “malicious”, detected directly by the AI model analyzing the prompt for agent manipulation attempts.

Pattern-Based Detection

For req_id=2, the model_verdict is “benign”, but pattern-matching detected a threat with category_type: tools-memory-manipulation, resulting in a malicious verdict.

Both requests were blocked according to the security profile settings.

Common Threat Patterns

Tool Memory Manipulation

  • Attempts to access or modify agent tool descriptions
  • Extracting system prompts or configurations
  • Bypassing tool access controls

Agent Goal Override

  • Commands to ignore previous instructions
  • Attempts to change agent objectives
  • Role manipulation attacks

Function Exploitation

  • Recursive tool calling patterns
  • Parameter injection attempts
  • Cross-tool attack chains

Use Cases

Agent Framework Protection

  • Secure AWS Agent Builder deployments
  • Protect Microsoft AutoGen applications
  • Safeguard LangChain implementations

Tool Security

  • Validate tool descriptions and parameters
  • Prevent unauthorized tool access
  • Monitor tool usage patterns

Workflow Integrity

  • Ensure agent goals remain unchanged
  • Detect workflow hijacking attempts
  • Maintain execution chain security

Performance Considerations

  • Asynchronous Processing: Batch multiple agent interactions
  • Model + Pattern Detection: Dual-layer protection
  • Framework Detection: Automatically identifies agent frameworks
  • Scalable Analysis: Handle complex multi-turn conversations
