    Although it has a user-friendly interface, mastering OllyDbg's more advanced features can be challenging for newcomers.
  • Inconsistent Updates

  • Potential Legal Issues
    Decompiling software can potentially breach intellectual property laws or terms of service agreements, depending on jurisdiction and specific use cases.
