since the signature was applied. If a single byte in a signed is modified, the signature becomes invalid, and Windows Defender SmartScreen may block the application. The Technical Mechanism of Unsigning

Furthermore, because the application cannot receive official updates, discovered vulnerabilities will remain unpatched. Conclusion
For the average user, the lesson is simple: For security professionals, monitor signtool usage like a hawk. And for the curious developer, remember that removing a signature is trivial; earning trust is not.
