# PRIMUS: A Pioneering Collection of Open-Source Datasets for Cybersecurity LLM Training

## 🤗 Primus-Seed

**Primus-Seed** is a high-quality🚀 cybersecurity text dataset composed of data crawled from reputable sources such as MITRE, Wikipedia, and well-known cybersecurity company websites, as well as CTI manually collected by our threat experts.

❗❗Currently, we have only released **Cybersecurity Companies Websites, Cybersecurity Wikipedia, and MITRE**. Other categories are under review to ensure compliance and verify whether redistribution falls under "_fair use_."

## How Did We Collect Cybersecurity Wikipedia?
_Wikipedia_ does not provide a predefined cybersecurity subset, so we perform a custom filtering process. Each Wikipedia article is associated with one or more category tags, which can be further expanded into subcategory tags. Starting from the root category "_Computer Security_", we recursively traverse its subcategories, using GPT-4o to determine whether a category is cybersecurity-related. This process yields **375** relevant categories, from which we extract corresponding Wikipedia articles.

_Prompt_:
```
[System]
You are a helpful assistant.
[User]
Help me identify and mark the categories related to "cybersecurity", "information
security", "data protection", "cryptography", "hacker activity", "cyber attack",
"cybercrime" from a list of categories I have.
For each category, provide a reason for marking it as 'Y' (Yes) or 'N' (No) in relation to the
specified topics. Finally, output the results in JSON format with the fields: category,
reason, security.
{{category-list}
```
