ratio-spoof

ratio-spof is a cross-platform, free and open source tool to spoof private bittorrent trackers the amount downloaded or uploaded by the peer.

Motivation

Here in brazil, not everybody has a great upload speed, and most of the private trackers requires a ratio to be greater than or equal to 1 (e.g. if you downloaded 1gb you must upload 1gb as well) in order to survive. Plus, i have always been fascinated by the bittorrent protocol, i even made a bittorrent webclient to learn a bit about it so with the current global covid-19 lockdown i got some free time and decided to code my own simple cli tool to spoof bittorrent trackers.

How does it works?

The way that a bittorrent protocol works is that there is no way that a tracker knows how much certain peer downloaded or uploaded, so it depends on the peer itself telling them how much they downloaded or uploaded.

Ratio-spoof acts like a normal bittorrent client but without downloading or uploading anything, in fact it just tricks the tracker pretending that.

Usage

With a recent python3 version installed, you will be able to run it on linux/macos/windows.

usage: ratio-spoof.py [-h] -t <TORRENT_PATH> -d <INITIAL_DOWNLOADED> <DOWNLOAD_SPEED> -u <INITIAL_UPLOADED> <UPLOAD_SPEED>

ratio-spoof is a open source tool to trick private trackers

optional arguments:
  -h, --help            show this help message and exit

required arguments:
  -t <TORRENT_PATH>     path .torrent file
  -d <INITIAL_DOWNLOADED> <DOWNLOAD_SPEED>
                        required download arg values
  -u <INITIAL_UPLOADED> <UPLOAD_SPEED>
                        required upload arg values

<INITIAL_DOWNLOADED> and <INITIAL_UPLOADED> must be in %, b, kb, mb, gb, tb
<DOWNLOAD_SPEED> and <UPLOAD_SPEED> must be in kbps

./ratio-spoof -d 90% 100kbps -u 0% 1024kbps -t (torrentfile_path) 

• Will start "downloading" with the initial value of 90% of the torrent total size at 100 kbps speed until it reaches 100% mark.
• Will start "uploading" with the initial value of 0% of the torrent total size at 1024kbps (aka 1mb/s) indefinitely.

./ratio-spoof -d 2gb 500kbps -u 1gb 1024kbps -t (torrentfile_path) 

• Will start "downloading" with the initial value of 2gb downloaded if possible at 500kbps speed until it reaches 100% mark.
• Will start "uploading" with the initial value of 1gb uplodead at 1024kbps (aka 1mb/s) indefinitely.

Will i get cought using it ?

Depends wether you use it carefuly, Its a hard task to catch cheaters, but if you start uploading crazy amounts out of nowhere or seeding something with no active leecher on the swarm you may be in risk.

Bittorrent client supported

The currently emulation is hard coded to be a popular and accepted client qbittorrent v4.0.3.
