Ghostseeder
This Python script spoofs seeding of torrent files to private trackers by sending fake announces.
Private trackers usually reward bonus points for seeding a lot of torrents. But at the same time, trackers don't have an explicit way to verify you actually have the files
Setup
Tested with Python v3.9+
$ git clone https://github.com/jephdo/ghostseeder.git
$ python -m pip intall .
$ python -m ghostseeder --help
usage: __main__.py [-h] -f FOLDER [-p [PORT]] [-v VERSION]
Enter path to a directory of torrent files
optional arguments:
-h, --help show this help message and exit
-f FOLDER, --folder FOLDER
A directory containing `.torrent` files. Torrent files should be from a private tracker and the announce url should contain your unique passkey
-p [PORT], --port [PORT]
The port number announced to the tracker to receive incoming connections. Used if you want to change the port number announced to the tracker. Optional, defaults to `6881`
-v VERSION, --version VERSION
The version of qBittorrent that you want to announce to the tracker. This info is used to generate the peer id and user agent string. Setting `-v '3.3.16'` will use qBittorrent
v3.3.16. Optional, defaults to `'4.3.9'`
-r MAX_REQUESTS, --max-requests MAX_REQUESTS
Maximum number of allowed HTTP announces per second. Useful especially at startup to mitigate sending a large burst of announces at once.
-s SEED, --seed SEED Optional random seed used to make peer-id generation deterministic
Script will announce itself as a qBittorrent client
Example Usage
Add torrent files to a folder:
$ tree torrents/
torrents/
├── archlinux-2022.11.01-x86_64.iso.torrent
├── freebsd
│ ├── FreeBSD-11.4-RELEASE-amd64-disc1.iso.torrent
│ ├── FreeBSD-12.2-RELEASE-amd64-disc1.iso.torrent
│ └── FreeBSD-13.1-RELEASE-amd64-disc1.iso.torrent
└── ubuntu-22.10-desktop-amd64.iso.torrent
1 directory, 5 files
$ python cli.py -f torrents/
The script will search for all .torrent files in the folder passed to it. For example, run this on your server/seedbox:
$ nohup python -m ghostseeder -f torrents/ &>> output.log &
This will run the script in the background and store logs in output.log
Example output
$ python -m ghostseeder -f torrents/ -p 59097

Example Docker Usage
A Dockerfile is provided and you can run the script as a Docker container by attaching
a volume containing torrent files. You can specify optional environment variables to change
the port and qBittorrent version:
$ docker build --tag ghostseeder-docker .
$ docker run --name ghostseeder --volume ./torrents:/torrents --detach --env PORT=59097 --env VERSION=4.4.5 ghostseeder-docker
Details of this script
Every private torrent has an announce url to the tracker containing a unique passkey (e.g. https://flacsfor.me/123456789abcdefg37ss9t0awe3dlyqs/announce). When a torrent client begins seeding a torrent, it uses this url to send parameters describing the current state of the torrent (including how much has been downloaded and uploaded). All information about the torrent is self-reported by the client.
Key request parameters to modify are info_hash and left. info_hash identifies the specific torrent and left states how many bytes needed to finish downloading the torrent. This script repeatedly sends HTTP requests to the tracker, setting left=0, declaring to the tracker that you are actively seeding the torrent:
GET https://flacsfor.me/123456789abcdefg37ss9t0awe3dlyqs/announce?info_hash=%D5E%DB%06v%15D%8CLx%21%3B%C5v%1DNf%8E%1B4&peer_id=-qB4450-OcPetHlvbFeW&uploaded=0&downloaded=0&left=0&compact=1&port=6881
