Apple Inc issued a patch on Thursday to fix a dangerous security hole in iPhones and iPads after researchers discovered that a prominent United Arab Emirates dissident s phone had been targeted with a previously unknown method of hacking.
The attack on the dissident, Ahmed Mansoor, used a text message that invited him to click on a web link.
Instead of clicking, he forwarded the message to researchers at the University of Toronto s Citizen Lab.
Experts there worked with security company Lookout and determined that the link would have installed a program taking advantage of a flaw that Apple and others were not aware of.
The researchers disclosed their findings on Thursday.
The researchers said that they had alerted Apple, which developed a fix and distributed it as an automatic update to iPhone 6 owners.
