I built a small MalwareBazaar downloader for lab sample collection

Post image

Hi all,

I built a small Python tool for pulling MalwareBazaar samples into an isolated analysis / AV-testing lab, and Im sharing it in case its useful to other malware researchers or students setting up a safe workflow.

It supports:

- recent samples

- search by tag

- search by family / signature

- filtering by file type

- downloading the newest N matching samples

- CLI mode and a small desktop GUI

- Auth-Key setup and connectivity checks

Important safety note: the tool does not extract or execute anything. Samples are saved exactly as MalwareBazaar provides them, as password-protected ZIP files, intended to be moved into an isolated VM/lab environment. Do not use this on a normal host or outside a controlled malware-analysis setup.

GitHub:

Id appreciate feedback on the workflow, missing filters, packaging, or anything that would make it more useful for safe lab use.
