A real-world example shows an agent correctly denying a request for a specific company's data but leaking other firms' data on a generic prompt. This highlights that agent security isn't about blocking bad prompts, but about solving the deep, contextual authorization problem of who is using what agent to access what tool.

AI models are designed to be helpful. This core trait makes them susceptible to social engineering, as they can be tricked into overriding security protocols by a user feigning distress. This is a major architectural hurdle for building secure AI agents.

AI 'agents' that can take actions on your computer—clicking links, copying text—create new security vulnerabilities. These tools, even from major labs, are not fully tested and can be exploited to inject malicious code or perform unauthorized actions, requiring vigilance from IT departments.

Despite their sophistication, AI agents often read their core instructions from a simple, editable text file. This makes them the most privileged yet most vulnerable "user" on a system, as anyone who learns to manipulate that file can control the agent.

The core drive of an AI agent is to be helpful, which can lead it to bypass security protocols to fulfill a user's request. This makes the agent an inherent risk. The solution is a philosophical shift: treat all agents as untrusted and build human-controlled boundaries and infrastructure to enforce their limits.

Beyond direct malicious user input, AI agents are vulnerable to indirect prompt injection. An attack payload can be hidden within a seemingly harmless data source, like a webpage, which the agent processes at a legitimate user's request, causing unintended actions.

The CEO of WorkOS describes AI agents as 'crazy hyperactive interns' that can access all systems and wreak havoc at machine speed. This makes agent-specific security—focusing on authentication, permissions, and safeguards against prompt injection—a massive and urgent challenge for the industry.

AI agents can cause damage if compromised via prompt injection. The best security practice is to never grant access to primary, high-stakes accounts (e.g., your main Twitter or financial accounts). Instead, create dedicated, sandboxed accounts for the agent and slowly introduce new permissions as you build trust and safety features improve.

AI agents are a security nightmare due to a "lethal trifecta" of vulnerabilities: 1) access to private user data, 2) exposure to untrusted content (like emails), and 3) the ability to execute actions. This combination creates a massive attack surface for prompt injections.
