Attackers may exploit this vulnerability when users visit compromised (but seemingly legitimate) websites. The exploit can also be triggered automatically without any user interaction, allowing attackers to extract sensitive data, including crypto wallet information. The malware may also erase its traces after execution, making detection extremely difficult.
Devices utilizing iOS 18.4-18.7 may be at risk, requiring immediate action. In this light, users are urged to immediately update their iPhone/iPad to the latest iOS version in order to remain safe.
