| # Benign and Malicious PowerShell Scripts |
|
|
| ## Dataset summary |
|
|
| This dataset contains **30,595 high-quality PowerShell scripts** for binary benign/malicious classification and static-analysis research. It includes both unobfuscated and heavily obfuscated PowerShell, with obfuscation techniques including—but not limited to—multiple encoding schemes. |
|
|
| All published samples were validated as parseable with Microsoft's official PowerShell parser, `System.Management.Automation.Language.Parser`, and can be converted into a PowerShell abstract syntax tree (AST) without executing the script. |
|
|
| > **Safety warning:** This dataset contains potentially malicious PowerShell code. Treat every sample as untrusted. Do not execute samples on a host system. Use isolated, non-production environments and static-analysis tooling only. |

| ## 中文简介 |
|
|
| 本数据集包含 **30,595 份高质量 PowerShell 脚本**，覆盖良性与恶意两类样本，适用于二分类、静态分析、恶意代码检测、混淆识别及基于 AST 的研究。 |
|
|
| 数据中包含大量高质量混淆样本，混淆方式包括但不限于多种编码方式。所有公开样本均已验证能够通过微软官方 PowerShell 解析器 `System.Management.Automation.Language.Parser` 成功解析并提取抽象语法树（AST），无需执行脚本。 |
|
|
| > **安全提示：** 数据集中可能包含恶意代码。请将所有样本视为不可信内容，不要直接执行；建议仅在隔离、非生产环境中进行静态分析。 |

| ## Key characteristics |
|
|
| - **Task:** binary classification of PowerShell scripts |
| - **Content:** benign and malicious `.ps1` files |
| - **Total samples:** 30,595 |
| - **Obfuscation:** includes multiple encoding and other PowerShell obfuscation techniques |
| - **Syntax quality:** every sample is parseable by the official PowerShell AST parser |
| - **Representation:** one script per file, organized by numeric label |
| - **Source split traceability:** original split, shard, and row identifiers are retained in filenames |
