h1-asset-fetcher 1.1.1

Fetch, download, and decompile mobile/exe assets from bug bounty programs

H1 Asset Fetcher

A terminal tool for bug bounty hunters that fetches, downloads, and decompiles mobile app assets from bug bounty programs.

It pulls in-scope Android, iOS, and Executable assets from HackerOne, Bugcrowd, Intigriti, YesWeHack, and Immunefi, bulk-downloads the APKs, and decompiles them for review — all from one guided, interactive prompt.

Install

pipx install h1-asset-fetcher      # or: pip install h1-asset-fetcher

This gives you the h1-asset-fetcher command. The APK download and decompile steps also need apkeep and jadx, which the bundled installer fetches for you:

git clone https://github.com/0xbartita/h1-asset-fetcher.git
cd h1-asset-fetcher && ./install.sh

Usage

Just run it with no arguments — it walks you through the whole pipeline, one question at a time, inline in your terminal:

h1-asset-fetcher

It guides you through, in order:

1. Platform — HackerOne, Bugcrowd, Intigriti, YesWeHack, or Immunefi
2. Credentials — token (and username where needed); reused on later runs
3. Scope & filters — android / ios / exe / all, program filter, bounty-only, out-of-scope
4. Fetch — pulls in-scope assets to output/<scope>/
5. Download — pick which assets to grab; APKs fetched via apkeep (apk-pure → huawei → f-droid)
6. Decompile — optionally run jadx on the downloaded APKs

Press Enter to accept each default, or Esc / Ctrl-C to quit.
