Example Archive
Archive Name
sample-package.deb Typical Usage
Debian packageWhy teams choose this tool
- Handles common firmware formats like 7z, tar.xz, and ISO
- Preview scripts and metadata before exporting
- Download only the sections you need for RE tools
- Sandboxes everything offline for sensitive investigations
Workflow
- Load the firmware archive from your test bench or vendor portal.
- Inspect boot scripts, configs, or binary blobs inside the image.
- Export selected files for analysis in IDA, Ghidra, or Binwalk.
Format quick facts
Unix AR archives bundle object files and are the container format for Debian (.deb) packages.
Supported extensions: .ar, .deb
Best for
- Analyzing router or IoT firmware drops
- Extracting configuration defaults for comparison
- Investigating suspected malware inside appliance updates
- Preparing partial updates for lab flashing
Pitfalls to watch
- Some firmware images use custom formats; if detection fails, repackage with a supported tool first.
- Encrypted sections still require vendor keys or passphrases.
- Preserve offsets when necessary by downloading the entire archive for tooling like Binwalk.
Common questions
Will this modify the firmware image?
No. We only read archive contents. Use the download buttons to export files—the original image stays untouched.
Can I preview scripts or plain-text configs?
Yes. Select a file to view its metadata and quick content preview before deciding to download it.
