Apple Inc AAPL.O has warned its users in India and 91 other countries that they could be victims of a "mercenary spyware attack," according to a threat notification email sent to targeted users.
The company discovered that attackers tried to "remotely compromise the iPhone," Apple said in the notification email seen by Reuters.
Mercenary spyware attacks are rare and vastly more sophisticated than regular cybercriminal activity or malware, according to the notification email.
