# Winrar

> Use for tightly scoped archive creation, compression, and packaging during authorized pentests. Trigger on approved evidence packaging, transfer-path simulation, and validating how compressed archives interact with endpoint or transfer controls.

# WinRAR

## Purpose

Use this skill for approved archive packaging when the assessment needs a Windows-native or environment-specific archive workflow.

## Phase Fit

- Primary: Validation and Controlled Impact Demonstration
- Secondary: Reporting, Retest and Closure

## Use When

- Need to package approved evidence or sample data in a Windows environment.
- Need to validate whether compressed archives affect an approved transfer path.
- Need a repeatable archive workflow for retest.

## Avoid When

- Archive scope exceeds the approved proof path.
- Passwording or staging archives is not explicitly approved.

## Inputs

- Approved file scope
- Archive and retention requirements
- Transfer or reporting goal

## Procedure

1. Archive only the minimum approved file set.
2. Record exact archive options and file scope.
3. Use the archive only for the approved objective.
4. Preserve or dispose of the archive according to engagement rules.
5. Repeat the same packaging path during retest if needed.

## Command Syntax

Replace sample paths with approved in-scope files.

```cmd
:: Create an archive
Rar.exe a contoso-evidence.rar evidence\

:: Create a password-protected archive
Rar.exe a -p<password> contoso-evidence.rar evidence\

:: AES-256 encryption with RAR5 format
Rar.exe a -p<password> -ma5 -m5 contoso-evidence.rar evidence\

:: Split archive into 100 MB parts
Rar.exe a -v100m contoso-large.rar C:\large-folder\

:: List contents
Rar.exe l contoso-evidence.rar

:: Extract archive
UnRAR.exe x contoso-evidence.rar C:\temp\out\
```

## Evidence to Capture

- Exact file scope placed into the archive
- Archive options and resulting artifact path
- Why archive packaging mattered to the assessment objective

## Safety Boundaries

- Keep archive scope minimal and approved.
- Protect archives as sensitive evidence when they contain assessment data.
