I understand that sharing video, photos, documents etc. is relatively safe because the data is not executed in the processor as instructions. How come people are willing to download and install pirated software though? How can one be confident that it does not contain malicious addons? Are people just don’t know the risks? Or are there protection mechanisms that I am missing? I mean since the software is usually cracked there is not much use in comparing checksums with the originals, is it?
If you get the crack from a reputable source, you can trust it will be safe. A low seed torrent from a shady place (like The Pirate Bay) is probably a virus. High seed torrent from another source like 1337x or something with more active moderation is generally safe.
If you want to be extra sure, spin up a VM and install the crack there and check it out before doing it on your real machine.
