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?
Worth noting that paying for a license for software doesn't stop it being spying malware either. In fact the pirate versions often take out the spying and the reporting-to-homebase that proprietary software does.
The photoshop that phones home to check a license is arguably more malicious than the pirate version that has been cracked so it doesn't do that.
