Apple notified multiple individuals this week who were believed to be targeted with government spyware.
Italian journalist Ciro Pellegrino and Dutch activist Eva Vlaardingerbroek were among those who received notifications from Apple.
Previous instances of such notifications have been made by companies like Apple, Google, and WhatsApp to alert users of spyware attacks.
The spyware campaign related to the recent Apple notifications is not yet clear, but previous cases have involved spyware developed by companies selling technology to governments.
