Honeypots are essential tools in cybersecurity. However, most of them lack the realism required to engage human attackers. This limitation makes them easily discernible, hindering their effectiveness. This work introduces a novel method to create dynamic and realistic software honeypots based on Large Language Models. Our method consisted of using an LLM for simulating a Linux terminal that can be used in real life through a secure shell (SSH). The preliminary results indicate that LLMs can create credible and dynamic honeypots capable of addressing limitations with static responses and similar constraints that are present in previous implementations, reaching an accuracy rate of 0.92.
