Understanding Malware on iPhones
Malware, short for malicious software, is designed to infiltrate, damage, or disrupt devices without the user’s consent. While iPhones are generally more secure than other devices due to Apple’s stringent App Store policies and robust security features, they are not entirely immune to malware threats.

- Ransomware: Locks the device or encrypts data, demanding payment to restore access.
- Phishing: Uses deceptive messages to trick users into divulging personal information.

- Unfamiliar Apps: New apps appearing without your installation or consent.
