For assets, you would be distributing other people’s work without permission. Some companies scan online content for digital fingerprints of copyrighted material. Think Youtube content ID but they are other tools out there.
As for software you used without a license, the work you did doesn’t matter in that regard, you’re only liable for using unlicensed software by bypassing copyright protection methods. You’re not distributing it. Their DRM (even cracked) might send them enough identifiable information to sue you (in theory).

How do companies know if I use cracked software or assets for my personal gig?
For context, I want to run a small personal gig (offering stuff on Patreon). Nothing too fancy....
