I can't find the vulnerability this attack uses. All that page says is "Beware! text files with subtitles can hack your computer" and links you to some sponsors media players and a video of someone capturing a screen two times.
All the other websites I found just copy the text and link to that page.
You can see OP in the comments there talking shit about C and promoting those badly written programs.
What a fucking low energy beta media player faggot cuck.
