@piracy How do i check if a crack is safe or not?

I'm trying to install a cracked version of davinci resolve on my pc, but I don't know if it's safe. is there a way to check easily?

Test strips. PSA: Everyone should test their drugs and carry narcan.

I was gonna say "have someone else smoke it first"

And don't use alone, pretty tricky to narcan yourself. Also gotta watch out lots of non-fentanyl tranqs getting mixed in with shit these days and narcan only works on opiods

Short answer: no, there’s not a way to check easily.

Long answer: don’t download form untrusted sources, if the crack is fully published on GitHub you can trust it more easily if the code is freely available and vetted by people who know what to look for.

If it's suss use a vm before your main OS.

This is a good idea and a good practice in my opinion. Some malicious code detects when it’s being sandboxed and hides itself until it’s running somewhere it can do damage though.

Once malware is VM aware it can also get outside a VM. Furthermore, malware can be written to seat itself comfortably in your PC and lay low for hours, days, weeks before becoming active. Installing in a VM and waiting for shit to hit the fan is not always reliable.

Getting out of a VM reliably is not usually trivial, and VM escapes are usually designed to target specific configurations rather than an arbitrary deployment. A VM with a minimum amount of shared resources is usually a reasonable security boundary unless you think the malware you’re analyzing has hypervisor-specific 0 days.

the malware has to be very advanced and specifically target your hypervisor version to escape a VM.

in the context of cracked software, it is highly improbable that you'll find malware with this capabilities.

If the installer is small enough (<650MB I believe), you can upload it to virustotal.com to have it be scanned by ~65 antivirus programs

You can't. They're never safe. But you aren't downloading a crack to be safe, are you? Use a sandbox to examine what it does, trust that it's safe, or don't use it.

Statistically though, cracks are safer than the software they're for though. Hope that helps.

first visual inspection: is there any rash or poop or anything nasty in there? then sniff.

Isn't DaVinci resolve free?

They pay wall hardware encoding, and possibly other features, like high resolution formats.

@ccdfa yeah but h264/mp4 exports are paid only from what I heard

On windows, the only features locked behind the paywall are required by professionals in film. This includes, but isn't limited to, larger than 4K timelines, 10 bit footage, advanced fusion filters and effects, niche export quality settings. As long as you're not working in the media industry, you won't need these.

Try the free version first, before jumping into a crack. See if you even like it.

You've heard incorrectly, as I use the free version to make videos of my terrible gameplay and I usually export to MP4 using H264.

They're limited only on Linux.

export it as some QuickTime/mov/whatever and recode it with handbrake.

Well, if your AV tells you there is a backdoor in it, don't open it, I would say. There can be valid reasons for cracks to be flagged, but you can usually check what it does by uploading it to a sandbox or checking the hash on virustotal.

A crack changes program code and is executed. There is no easy way to check if it is safe.

Unless you inspect the source code or binary code (directly or through reverse-engineering) you can not verify it.

What's left without that is attempts at gaining confidence through analysis trust of third parties - the providers, distributors, creators - who have to be confirmed beyond a matching text label too.

The alternative to or extension of being confidently safe or accepting the risk is to sandbox the execution. Run the crack in a restricted environment with limited access in case it does things you do not want to. Optionally monitoring what it does. Which has to be put into relation of what the program does without the crack.

Back when I used cracks often the cracks were small keygens and sometimes a patched main exe/dll, so I could just generate the key in a vm/sandboxed environment and inspect the patched binary, usually they did nothing weird. Huge repacks are often very sketchy though.. Nowadays there are many great FOSS alternatives so I tend to use them more.

I never used Linux before, is virus still a problem for cracked software on Linux?

It'll always be a problem for cracked software. But on Linux I find a good Free and open source alternative more readily than windows. I personally keep a good windows 10 VM around with snapshots for running software of dubious origins.

Typically, malware is harder to run on linux due the system asking for a sudo password for anything that requires administrator privlages. There are also plenty of other factors that i dont feel like getting into

Not to also mention most malicous applications are designed for windows, not linux.

Its mainly the market share thing really. Using good default policies on windows or Linux would kill a lot of malware but typical Linux users still just copy paste shit into the command line and add random repositories etc anyways. And a program running with my privileges in my home directory would be 99% as bad as it running as root since my machines are really just me using them.

your main concern would be files. If you run something as your usual suspect user, that software can do pretty much whatever it feels like with files under those permissions, unless sandboxed.

Not quite malware, but if someone wanted to troll you a goof rm -rf isn't hard.
