- Google has introduced a new framework called Project Naptime to enable an LLM to perform vulnerability research.
- The framework leverages the developments in LLMs’ code compression and general reasoning abilities to allow them to replicate human behavior regarding identifying and demonstrating security vulnerabilities.
Google has come up with a new framework, “Project Naptime,” which is expected to enable a large language model (LLM) that performs vulnerability research to improve automated discovery approaches. The name comes from the fact that it allows humans to take regular naps while the architecture helps automate variant analysis and vulnerability research.
At its core, the framework leverages the developments in LLMs’ code compression and general reasoning abilities. This allows LLMs to replicate human behavior regarding identifying and demonstrating security vulnerabilities.
According to Google Project Zero researchers Mark Brand and Sergei Glazunov, “The Naptime architecture is centered around the interaction between an AI agent and a target codebase. The agent is provided with a set of specialized tools designed to mimic the workflow of a human security researcher.”
The Google researchers further said, “Naptime enables an LLM to perform vulnerability research that closely mimics the iterative, hypothesis-driven approach of human security experts. This architecture not only enhances the agent’s ability to identify and analyze vulnerabilities but also ensures that the results are accurate and reproducible.”

The framework has several components, such as a Crowd Browser tool that allows the AI agent to navigate the target codebase. The Python tool runs the Python scripts in a sandbox environment for fuzzing, and a Debugger tool observes the program behavior with different inputs. A Reporter tool monitors a task’s progress.
According to Google, Naptime is also backend-agnostic and model-agnostic. Further, it is expected to be better at flagging advanced memory corruption and buffer overflow flaws, as per the CYBERSECEVAL 2 benchmarks released in April by Meta researchers. These benchmarks quantify LLM security capabilities and risks.
