Analyze specialized file types beyond standard PE executables - .NET assemblies, Office macros, PDFs, PowerShell scripts, JavaScript, archives, HTA files, disk images (ISO/IMG/VHD/VHDX), and Linux ELF binaries. Use when you encounter documents, scripts, disk images, or non-Windows executables that require format-specific analysis tools and techniques. Claude runs the extraction and deobfuscation tooling on the host itself; nothing is executed.

# Specialized File Analyzer

Expert analysis of non-PE file formats commonly used in malware campaigns: .NET, Office documents, PDFs, scripts, HTA files, disk images, archives, and Linux binaries.

## When to Use This Skill

Use this skill when analyzing:
- **.NET/C# assemblies** (.exe, .dll with .NET framework)
- **Office documents** with macros (.docm, .xlsm, .doc, .xls)
- **PDF files** (suspicious attachments, exploit documents)
- **Scripts** (PowerShell .ps1, VBScript .vbs, JavaScript .js)
- **HTA files** (.hta — HTML Applications executed by mshta.exe)
- **Disk images** (.iso, .img, .vhd, .vhdx — container formats that bypass MOTW)
- **Archives** (.zip, .rar, .7z, .tar.gz)
