# SauronEye
SauronEye is a search tool built to aid red teams in finding files containing specific keywords. 

**Features**:
- Search multiple (network) drives
- Search contents of files
- Search contents of Microsoft Office files (`.doc`, `.docx`, `.xls`, `.xlsx`)
- Find VBA macros in old 2003 `.xls` and `.doc` files
- Search multiple drives multi-threaded for increased performance
- Supports regular expressions in search keywords
- Compatible with Cobalt Strike's `execute-assembly`

It's also quite fast, can do 50k files, totaling 1,3 TB on a network drive in under a minute (with realistic file filters). Searches a `C:\` (on a cheap SATA SSD) in about 15 seconds.

### Notes
SauronEye does not search `%WINDIR%` and `%APPDATA%`. 
Use the `--systemdirs` flag to search the contents of `Program Files*`.
SauronEye relies on functionality only available from .NET 4.7.2, and so requires >= .NET 4.7.2 to run.
