This morning's news brought this story:
Hackers are hiding computer viruses in film subtitles, security experts warn
Where they warn that subtitles in videos played on computers could be used to deliver ransomware.
Yes we all know about steganography - hiding messages in jpegs and mp3s, and I don't doubt that a message could be hidden in video. But it seems a stretch to say that subtitles could somehow activate themselves and take over a computer.
So my question is simple: Does anyone here actually know of any cases where this has happened?
