DGAs, commonly employed by malware, generate dynamic domain names for **command-and-control (C&C)** servers, posing a significant challenge in cybersecurity. ## Model Description - **Base Model**: Llama3 8B - **Task**: DGA Detection - **Fine-Tuning Approach**: Qlora based supervised Fine-Tuning (SFT) with domain-specific data. - **Dataset**: A combined dataset comprising 59 malware families and legitimate domains consisting of three different sources: one dataset for benign domains, which includes the Alexa Top 1 Million Sites collection of reputable domains; and two datasets for DGA domains, sourced from Bambenek Consulting’s malicious algorithmically-generated domains and the 360 Lab DGA Domains. - **Performance**: - **Accuracy**: Known domain 98.6%, Unknown domain 80-99.5% - Excels in detecting unknown DGAs. This model leverages the extensive semantic understanding of Llama3 to classify domains as either **malicious (DGA-generated)** or **legitimate** with high precision and recall. ## Data The model was trained with 2.5 million domains, split between 1.5 million DGA domains and 1 million normal domains.
