You’re not executing a mkv or a pdf
You’re half wrong and half right, .mkv files are completely safe but the same can’t be said about .pdf files, attackers can embed malicious code, such as JavaScript or hidden executables, within a PDF file.
People really underestimate the capabilities of this .pdf file format. I remember some time ago, someone managed to run doom inside a .pdf file.
I pirated this meme in the highest quality I could but lemmy compresses the image to 60-70% of its original quality, that’s why it’s so blurry 😅
