We are investigating an issue where a user has downloaded torrents en masse and scraped associated peer data from the tracker. They are now attempting to download these torrents from anyone seeding.
At this stage we recommend everyone stop seeding their CRT torrents while we investigate

UPDATE:

Hello, I'm in a rush so I'll have to be very brief. Basically what happened was the same thing that happened in OPS, their announcement would be basically our announcement. If you are not in OPS, you can read it on Reddit.

We have implemented a basic measure to protect against future attempts, and more robust measures are in the way. More info on this later.

In the meantime, the tracker will be down to attract the attention of more users with the hope that they see the news. Downloads will be disabled because there's no point at the moment anyway.

The best thing you can do right now is to change the IP of your torrent client, if you can't, the next best thing is to change your client port. The goal is that the attacker can no longer connect to you. For those that can't change IPs or ports easily, try blocking the following IPs, which are 100% confirmed to be from the attacker:

62.210.38.82
62.210.131.104
95.216.9.233
135.181.74.216
148.251.238.249

If you notice any more suspicious IPs, please report them in a Staff PM.

I'm very sorry for the mess.
