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

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

Command Syntax

Replace sample paths with approved in-scope files.

:: 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.
