Rebuilt apps may not keep their audit trails.

Researchers used AI to reverse-engineer Slack, Apple Finder and malware from compiled binaries back into working source code. They then added new features like AI autocomplete to Slack. The technique shows that compiling software no longer protects the source.

The source does not say whether the reconstructed Slack retains the original's audit logs, access controls or compliance mechanisms. Reverse-engineered code may run identically but lack the safeguards enterprises rely on: login records, data-handling logs, or controls required by regulations.

For anyone building apps with AI tools or relying on no-code platforms, a digital witness would show which version of the system logged which actions. It would prove whether the app you deployed is the one with audit trails intact, not a functionally identical copy missing the records compliance officers expect. The difference matters when a regulator asks who accessed what, or when a partner disputes what the system did.
