I heard that it is possible to inject video containers with malware. I also heard malware is rampant on 1337x. And I don't have an antivirus to scan files for the moment cuz I'm on Linux, also it would be too much for me to upload the movie to virustotal.
I found a release that suits my need for the movie I'm looking for, but I don't know if I can trust this uploader (TGxGoodies). the number of seeders is over 120 for the movie.
the reason I'm reluctant is that a very active uploader on 1337x: IGGGAMESCOM is labeled "Vip Uploader" despite a simple search on reddit shows that there are victims for their malware-injected uploads.
I have downloaded several TV shows and movies from this uploader and had no issues AFAIK. But make sure to scan this before opening with any player.
