7zip

Use for tightly scoped archive creation, compression, and packaging during authorized pentests. Trigger on approved evidence packaging, transfer-size reduction, and validating whether archive controls or DLP-related assumptions affect the assessment.

7-Zip

Purpose

Use this skill for approved archive creation or packaging of limited assessment artifacts.

Phase Fit

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

Use When

Need to package approved assessment artifacts or evidence.
Need to test whether archive handling affects an approved transfer path.
Need a repeatable evidence-packaging workflow.

Avoid When

Archiving broader data than the approved proof path requires.
Password-protected or staged archives are not explicitly approved.

Inputs

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

Procedure

Archive only the minimum approved file set.
Record exact archive format and options used.
Use the archive only for the approved reporting or validation objective.
Preserve or destroy 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
7z a contoso-evidence.7z evidence/

# Create a password-protected archive
7z a -p'<password>' contoso-evidence.7z evidence/

# AES-256 encrypted archive (also encrypts file names)
7z a -p'<password>' -mhe=on contoso-evidence.7z evidence/

# Add specific file types
7z a contoso-docs.7z "C:\sensitive\*.docx" "C:\sensitive\*.xlsx"

# Split archive into 100 MB parts
7z a -v100m contoso-large.7z C:\large-folder\

# List archive contents
7z l contoso-evidence.7z

# Extract archive
7z x contoso-evidence.7z -o C:\temp\out\

Evidence to Capture

Exact file scope placed into the archive
Archive format and options used
Why packaging mattered to the assessment objective

Safety Boundaries

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