I recently downloaded subtitles for an episode of a series. I then looked at whether .srt files could contain a virus and found that that was indeed the case with some .srt files which exploited a vulnerability in a media player when loaded.
That info I found in an article from a year or 2 ago, so I wondered if this was still the case (especially for the default Android video player, I was planning to use the subs when watching the movie on my phone).
Another thing that bothered me was the fact that to check the contents of the .srt I used the website https://subtitletools.com/convert-subtitles-to-plain-text-online and downloaded a .txt of the .srt from there. I then disabled hidden extensions and opened the .txt with notepad, which sure enough revealed normal text.
Later, I saw the option to open the .srt file with Notepad++, but stupidly enough already downloaded the .txt from the website above.
That's why I am wondering whether there is a possibility of malware being present, in either the .srt or .txt (or both).
