iPhone-maker Apple Inc on Tuesday said it does not attribute threat notifications, such as the ones received by some MPs belonging to Opposition parties, to any specific state-sponsored attackers and that it cannot provide information on what causes such warnings, reported news agency PTI.

After some of the most vocal critics of the government said they received warnings that attempts have been made by state-sponsored attackers to steal information from their iPhones, Apple in a statement stated it is possible that some threat notifications may be false alarms and some attacks may not be detected, reported PTI.
