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.
It's partly an honor system but also, anyone distributing malicious cracks are quickly called out whether its on public tracker comments like PirateBay or removed from private trackers.
Distributors of GOOD and CLEAN cracks often earn good rep in the community too, like Monkrus which I've had no issue with before.
Also, in my experience, installing a malware-packaged adobe app isn't actually all that bad if you run a malware scan immediately afterwards. With the scale and breadth of software piracy there isn't much money in making advanced malwares beyond bundling an existing one into an installer. I don't recommend it, but it's still easier and cheaper than paying Adobe!
TLDR the community polices itself pretty well considering.
You're thinking too technical about this. This is a money thing. Personally speaking pirated software/games were chicken soup for my poverty ridden childhood.
Your assumption is wrong mail can contain executables. Picture can hold executable instructions and so do videos. For example videos and pictures in mail can contain virus. You are not safe just because you download movies and pictures
How come people are willing to download and install pirated software though?
You can just remove "priated" from that statement and come to the same conclusions. Considering the amount of bugs, backdoors and 0-day exploits distributed via official software I sometimes wonder why people execute proprietary, closed source programs at all.
An no, "reputable" companies mean nothing, just look at Microsoft clowning around with their signing keys.
Meh, how is surgery a thing? You let people just open you up and dig around your insides?
it's a mix of need and belief in a proper vetting process. For computers there's the additional layer that any one machine is probably low stakes. In early internet days most software was prohibitively expensive but gave you the equivalent of super powers - as a teenager / young adult with ability to take that risk you're not going to do it?
I installed trusted cracks from scene groups. Not everyone who can crack will be a scene group. To get into the scene you need to be well trusted. Scene groups would NOT damage their integrity to install something malicious through a crack
As another user said, check the files you have match the direct uploads from the scene with a site like predb.me
You can search online for more info on scene groups/warez/topsites
Most don't invest that much into anti-piracy protection and you can avoid it with simple firewall and GPEdit corrections for the unlimited premium spoof.
There are also the key gens that emulates the server or the software to receive the codes or give a confirmation to the software.
This is all very oversimplified and there are an infinite number of anti-piracy methods that the companies don't even want to try to solve since it's all free advertising and it gets people used to their software when they have to buy it.
It's one of those high-risk, high-returns case scenarios. You gamble. If you succeed, you will be saving some buck. Some software licences can be very, very expensive.
There is no way of knowing the answer to your questions. You just use your intuition and take a leap of faith.
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.
