Rebutting advice from the Department of Homeland Security and other sources that have sought to sow fear in users with regards to the "Masque" malware attack, Apple late on Thursday issued a statement saying it is unaware of any actual cases of the malware attacking iOS users. The statement comes on the heels of fast action by the iPhone maker to stop a similar attack dubbed "Wirelurker," in which a now-revoked Enterprise Provisioning certificate was being used to spread potential malware. Apple has not specified if it has fixed the flaw the Masque malware exploits.
