Break the Agent: An Agent Security CTF

​Sponsored by atoro.io | Security and compliance for startups

​Your job is simple: break the agent before someone else does.

​AI agents can browse the web, call APIs, access files and take actions on a user’s behalf. Every new capability creates another way things can go wrong.

​Break the Agent is a hands-on capture-the-flag challenge focused on agent security. You’ll test deliberately vulnerable agents, uncover weaknesses, and work through challenges based on failure modes such as prompt injection, data leakage, excessive permissions, and unsafe tool use.

​Expect less theory and more breaking, debugging and figuring out how these systems should be secured.

​What to expect

• ​A series of agent security challenges

• ​Vulnerable agents to test and break

• ​Challenges covering prompts, tools, permissions and data access

• ​Time to work with other engineers, security practitioners and AI builders

• ​A walkthrough of the vulnerabilities and possible fixes

​Challenge details and participation requirements will be announced soon.
