Apple is alerting users to a new instance of an identified mercenary spyware attack on the iPhone. Possible victims have been sent an email from Apple describing how the attack could “remotely compromise the iPhone”. Victims are being notified in India and 91 additional countries, via Reuters.
Mercenary attacks of this nature typically cost millions of dollars, and are often useless once discovered by security researchers and patched by iOS security updates. They are often believed to be state-sponsored, due to the high cost of development to craft such complex and sophisticated attacks. However, in a notable change of language, Apple no longer says this explicitly in its threat notifications.
