// Adversarial AI Security — OWASP LLM Top 10 · RAG · Agentic Security

Can Attackers Hijack
Your AI & LLM Systems?

As enterprises integrate generative AI, LLM chatbots, and autonomous agents, threat actors exploit prompt injections, RAG poisoning, and unauthorized tool invocation. CyberHQ performs elite AI Red Teaming to stress-test your AI safety guardrails.

Why Traditional Pentesting
Misses AI Vulnerabilities

LLMs process natural language as code. An attacker does not need to submit complex binary exploits — they use carefully crafted conversational prompts to bypass system rules, steal private vector embeddings, or force AI agents to run malicious actions.

CyberHQ's AI security specialists design custom adversarial payloads targeting your exact LLM pipelines, autonomous tool wrappers, vector databases, and system prompts.

Direct & Indirect Prompt Injections (manipulating AI via user inputs or untrusted web data)

System Prompt Extraction & Sensitive Data Exfiltration from RAG Knowledge Bases

Unauthorized Autonomous Tool Execution (forcing agents to send emails, execute SQL, or trigger APIs)

Case Study: FinTech Customer Support Agent

How an indirect prompt injection attack was neutralized before malicious actors could trigger unauthorized money transfers.

// SCENARIO

Client Setup

A digital banking startup deployed an autonomous customer support agent equipped with function calling to check balances and initiate fee refund requests up to $500.

// ATTACK FINDING

Vulnerability

By embedding a hidden prompt in a dispute invoice PDF, an attacker tricked the AI into ignoring system bounds and executing refund API calls to arbitrary accounts without human approval.

// RESOLUTION

Results

CyberHQ designed dual-layered guardrails with human-in-the-loop verification for financial calls and secondary prompt validation, eliminating 100% of exploit paths.
