AI security testing must treat AI-enabled apps as full-stack systems, not just chatbots that can be jailbroken for text outputs.
Briefing
AI-enabled apps are becoming an easy target because attackers can chain multiple weaknesses—inputs, surrounding systems, and the model itself—into practical data theft and account compromise. The core message is that “hacking AI” isn’t limited to jailbreaks that make a chatbot say forbidden words; it also includes stealing sensitive information, manipulating business logic, and pivoting from the model to the broader software ecosystem. That matters because many organizations are rushing to deploy AI features without matching the security rigor used for traditional web and API systems.
A central framework introduced around AI security testing splits the work into a holistic “AI pen test” approach rather than narrow “AI red teaming” that focuses only on getting harmful outputs. The methodology uses six repeatable segments: identify system inputs, attack the ecosystem around the AI application, and then attack the model (including attempts to induce harmful or biased behavior). The playbook continues through prompt engineering attacks, data attacks, application attacks, and finally pivoting to other systems—turning model interaction into a pathway for real-world impact.
The most emphasized technique is prompt injection, described as the primary “vehicle” for many of these attacks. Prompt injection can work with little or no coding skill at first: attackers rely on clever natural-language instructions to trick an LLM into following malicious directives embedded in user content or indirect signals. A key warning is that defenses that look strong in early tests often fail against more advanced variants, especially once guardrails and filters are in place.
To make prompt injection learnable, Jason Haddock’s taxonomy organizes attacks into intents (what the attacker wants, such as leaking a system prompt or extracting business information), techniques (how to achieve the intent, including evasion strategies), and utilities (supporting mechanisms). The taxonomy also frames attacks as a mix of intense techniques, evasions, and utilities—because successful attacks often depend on bypassing specific controls rather than one universal trick.
Concrete examples show how attackers evade modern classifiers and guardrails. “Emoji smuggling” hides instructions inside emoji metadata so the model interprets hidden directives even when classifiers miss them. “Link smuggling” uses encoded data embedded in image URLs: the model is induced to attempt a fetch, and server logs reveal the exfiltrated content. For image generation, a “syntactic anti classifier” approach reframes requests through synonyms, metaphors, and indirect phrasing to bypass restrictions.
The transcript also stresses that the AI attack surface expands as AI becomes more agentic and tool-using. Over-scoped API permissions and weak input validation can let an agent write back into systems like Salesforce, enabling malicious actions through prompt injection. Even newer standards such as MCP (Model Context Protocol) can widen risk: MCP servers may lack role-based access control, may allow file access for parsing or RAG memory, and can be backdoored by altering prompts or tool behavior. The result is a “Wild West” dynamic where powerful AI components and integrations outpace security controls.
Defense in depth is presented as the practical answer: secure the web layer with input/output validation, add an “AI firewall” (classifier or guardrail) around the model for both inbound and outbound prompts, and enforce least-privilege on API keys and tool permissions. As systems coordinate multiple agents, the challenge grows harder because each component must be protected without destroying performance—making trade-offs unavoidable. The overall takeaway is that AI security is now a full-stack problem, and the same urgency that once drove web hacking defenses is arriving for AI.
Cornell Notes
AI hacking is framed as a full-stack security problem, not just jailbreaks that force harmful chatbot outputs. A six-part “AI pen test” methodology targets inputs, the surrounding ecosystem, the model itself, prompt engineering, data, application behavior, and then pivots to other systems. Prompt injection is highlighted as the main attack path because it can often be executed with clever natural-language prompting and can bypass guardrails using techniques like emoji smuggling and link smuggling. Real-world risk increases when AI agents call tools and APIs with weak validation or overly broad permissions, including in integrations built on standards like MCP. Defense centers on layered controls: web-layer validation, an AI firewall for inbound/outbound prompts, and least-privilege access for APIs and tools.

Review Questions
- How does the six-part AI pen test methodology differ from narrower AI red teaming focused only on harmful outputs?
- Which prompt-injection examples rely on metadata, encoded URLs, or indirect phrasing, and what control do they attempt to bypass?
- Why can least-privilege API scoping be as important as prompt filtering when AI agents can call tools?
Key Points
- 1
AI security testing must treat AI-enabled apps as full-stack systems, not just chatbots that can be jailbroken for text outputs.
- 2
Prompt injection is positioned as the main attack path because it can redirect LLM behavior using attacker-controlled instructions embedded in prompts or signals.
- 3
A structured taxonomy of prompt injection helps classify attacks by intent, technique, and utility, making defenses and testing more systematic.
- 4
Evasion tactics like emoji smuggling and link smuggling show how hidden directives or encoded data can bypass common guardrails and classifiers.
- 5
Over-scoped API permissions and missing input validation can let prompt injection escalate into unauthorized reads/writes in systems such as Salesforce.
- 6
Standards and frameworks like MCP can expand the attack surface if MCP servers lack role-based access control or allow unsafe file/tool access.
- 7
Defense should be layered: web-layer validation, an AI firewall for inbound/outbound prompts, and least-privilege access for tools and APIs—especially when agents coordinate multiple actions.
