Someone’s watching LTT,

Yes a PDF can be malicious if it’s not really a PDF, but code designed to LOOK alike a pdf to you and to your computer.

I can right now make a script and change it’s icon and extension and windows will be sure it’s a PNG file, I double click it and a shell script runs in a CMD prompt then vanishes. What did it do? Who knows.. am I in trouble? Almost certainly.
