It aims to uncover hidden strategies in complex agent behavior such as penetration testing and cybersecurity assessment. By converting raw execution traces into finite‑state models, ATLAS enables systematic analysis of decision points, success paths, failures, and recurring patterns. ## Key Contributions - [Finding 1] The authors develop a novel method that merges LLM‑guided abstraction with automata learning to infer human‑interpretable finite‑state behavioral models from agent trajectories. - [Finding 2] ATLAS produces explicit symbolic models that expose high‑level strategies (e.g., exploitation patterns) which are invisible in raw logs, enabling explainability and automated auditing. - [Finding 3] The framework demonstrates model‑guided knowledge transfer, compressing the knowledge of frontier LLMs into compact language models while preserving behavioral insight. ## Methodology The authors start with a set of LLM‑generated penetration‑testing traces across twelve vulnerable machines. First, they apply trace abstraction to collapse sequences of actions and states into observable events and transitions. Next, they feed these abstracted traces into an automata learning algorithm that searches for the minimal deterministic finite automaton (DFA) whose behavior matches the observed sequence. The resulting DFA is then encoded as a symbolic model that can be interpreted by humans or used programmatically. ## Results Experiments show that ATLAS recovers models with up to 85 % accuracy in predicting whether an agent will succeed on a given task, compared to baseline methods that rely solely on execution traces. The recovered automata expose clear decision branches: e.g., “check for outdated software → attempt exploit” and “detect anomaly → escalate alert”. In the knowledge‑transfer demo, a 70‑parameter language model reproduces the behavior of a 128‑parameter frontier model with minimal loss in strategy fidelity. Symbolic explanations reduce trace length by an average of 63 % while preserving all strategic information. ## Significance ATLAS bridges the gap between black‑box LLM agents and human‑readable models, fostering trustworthy AI systems. By providing interpretable behavioral artifacts, it supports explainability, auditing, model‑guided exploration, and systematic engineering analysis—critical for high‑stakes domains like cybersecurity. ## Related Concepts - Trace abstraction: compressing raw logs into event sequences. - Automata learning: inferring finite‑state models from data. - Symbolic AI: representing knowledge in discrete states and transitions. - Knowledge transfer: transferring model capabilities to smaller models.
