Suspected Xunlei / PikPak offline download server `libtorrent/2.0.7.0` #526

Closed FrzMtrsprt closed 6 months ago

FrzMtrsprt commented 6 months ago

qBittorrent & operating system versions

qBittorent v4.6.2.10 Operating System: Windows 11 Pro 23H2 Qt: 6.4.3 libtorrent-rasterbar: 1.2.19.0

What is the problem?

According to discussions on the internet (see discussions on itzmx and cometbbs), Xunlei and PikPak has updated their offline download server to using libtorrent 2.0.7.0.

These clients have peer ID -LT2070-, client name libtorrent/2.0.7.0, and their ports range from 6881 to 6884 (there might be more, but I'm not sure).

They keep their upload speed under 10KB/s, but they keep downloading from others.

Note that in my screenshot, some of the libtorrent 2.0.7.0 clients are from Netherlands. I think these are PikPak's offline download server, since PikPak's server is located in Netherlands (see reddit), and they also seem to use Xunlei's offline downloading SDK (see here)

I also checked their download history on https://iknowwhatyoudownload.com (see result for 120.72.33.132 and result for 218.91.199.15), it show that they download hundreds of torrents every day. This further proves that they are offline download servers. In fact, if you search libtorrent/2.0.7.0 site:iknowwhatyoudownload.com on Google, you can see many more similar results.

Steps to reproduce

  1. Download 6a7200535fee91cef8887c931d4f60ffa509e7b3 with qBittorrent Enhanced Edition
  2. Observe the peer list

You can enable Auto ban Unknown Peer from China, it should be auto ban libtorrent/2.0.7.0 peer which come from Netherlands or China. image https://github.com/c0re100/qBittorrent-Enhanced-Edition/blob/v4_6_x/src/base/bittorrent/peer_blacklist.hpp#L29-L41

I see, I thought Auto ban Unknown Peer from China bans all of the non white listed peers from China. I think this option can have a better name. Anyway, thanks for clarifying!

Is there any human (rather than a server) using libtorrent?

I was writing a Shell script for Transmission, but it's not easy to implement features like qee, so I was wondering what if I simply block all of libtorrent.

libtorrent 这个客户端是否有人类用户使用？我给 Transmission 写的 Shell 脚本，打算干脆屏蔽所有的 libtorrent
