  • How AI Transformed Our Penetration Testing Approach

We’ve always prided ourselves on delivering thorough, manual penetration tests that uncover vulnerabilities automated scanners often miss. But in early 2025, we began integrating AI-assisted exploitation techniques into our engagements — and the results have been nothing short of revolutionary.

The Problem: Manual Testing Bottlenecks

Traditional pen testing workflows involve hours spent manually exploring attack surfaces, crafting custom payloads, and validating complex vulnerabilities like business logic flaws or API authentication bypasses. While effective, this approach is time-intensive and can miss subtle edge cases — especially in large-scale applications with hundreds of endpoints.

The AI Solution: Adaptive Exploitation Frameworks

We implemented an AI-driven exploitation framework that integrates directly with our Burp Suite workflow. This system uses a fine-tuned LLM (specifically, GPT-4o-pentest) trained on 12,000+ real-world exploit cases from OWASP Top 10, CVE databases, and internal historical findings.

Here’s how it helped us exploit vulnerabilities we previously overlooked:

Case Study: API Authentication Bypass in a Toronto FinTech Client

Our client’s mobile banking app had an API endpoint (/api/v2/user/profile) that appeared secure with JWT tokens. Traditional testing confirmed token validation but missed the contextual bypass.

The AI system analyzed 870 API requests across multiple sessions and identified a pattern: when user-agent headers contained “iOS/16” followed by specific device model identifiers, the backend skipped role-based access control checks — even with valid tokens.

We fed this observation into our AI assistant, which generated three custom exploitation payloads:

  1. A modified JWT payload that injected {"role": "admin", "device_model": "iPhone14,2"}
  2. An automated Burp Intruder attack targeting 37 different user-agent variations
  3. A Python script using requests+httpx to simulate device fingerprint spoofing

The AI didn’t just suggest the exploit — it predicted the likelihood of success (96% confidence) based on historical exploitation data from similar fintech clients in our Toronto region.

Result: We discovered a critical vulnerability allowing low-privilege users to access admin-level financial transaction logs. The client patched this before launch, avoiding potential regulatory fines under Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA).

Beyond Exploitation: AI as a Co-Pilot

Our AI doesn’t replace testers — it augments them:

  • Automated Payload Generation: For every new vulnerability class found, the AI generates 5–10 exploitation variants in seconds.
  • Risk Prioritization: It cross-references findings with CVSS scores, exploit availability (GitHub PoCs), and business context to rank risks by real-world impact.
  • Reporting Intelligence: Automated report sections now include attack chain visualizations, root cause analysis derived from code patterns, and mitigation recommendations tailored to the client’s tech stack.

The Future: AI That Learns From You

We’re now training our model on our own past engagements. Each successful exploit we document becomes new training data — making our AI smarter with every test. In one recent engagement, it correctly predicted a blind SSRF vector in a legacy Java application based on patterns from three prior Toronto healthcare clients.

Conclusion: Human Expertise + AI Power = Unbeatable Results

AI isn’t just speeding up pentesting — it’s enabling us to find vulnerabilities we didn’t even know to look for. At gethacked.ca, we now deliver deeper, faster, and more insightful assessments than ever before.

If you’re a business serious about security, let’s talk about how AI-powered penetration testing can uncover the hidden flaws in your systems — before attackers do.
