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?
Get software from reputable private trackers only
This is one of the single most important pieces of advice. Unless you have access to topsites, then this is about as close to the source as you are going to get, except for FitGirl repacks that can be DDLd from her site.
