Apple threat notifications: What is mercenary spyware and how to protect against it

Apple recently alerted customers who they suspected had been targeted with spyware on their devices. The company sent these notifications to users in 110 countries, reminding them about the advanced digital threat known as mercenary spyware. In this article, we'll explain what these alerts mean, why they are sent, and what you should do if you receive one.

Mercenary spyware is a highly sophisticated form of cyberattack, significantly more advanced than regular cybercrime. These operations involve significant resources and target a very specific group of people and their devices. Apple states that these attacks often cost millions of dollars, are difficult to detect, and usually last only briefly.

Most users will never encounter such an attack, as these incidents are typically linked to state actors or private firms building spyware for governments, like NSO Group's Pegasus tool.

If you receive an Apple threat notification, Apple recommends turning on Lockdown Mode and contacting specialized organizations such as the Digital Security Helpline run by Access Now, which provides emergency security assistance. Regardless of whether you encounter mercenary spyware or not, there are basic cybersecurity practices you should follow.

Keep your devices updated with the latest software, use strong and unique passwords, enable two-factor authentication, install apps only from the App Store, and avoid clicking on links or opening attachments from unknown senders.
