Apple releases iOS 9.3.5 update, bringing security update

Apple has released iOS 9.3.5, another important update for its iOS 9 operating system, addressing serious security holes apparently exploited by an Israeli hacking firm. Apple has characterized the latest build as an “important security update” recommended for all users.

According to The New York Times, the issues were said to be exploited by an Israeli company called the NSO Group that specializes in tracking the mobile phones of targets.

While it’s unclear just how much access the NSO Group had to devices running iOS 9, Thursday’s report noted that the group had developed software that could read text messages, emails, calls, contacts and more.

“Investigators discovered that a company called the NSO Group, an Israeli outfit that sells software that invisibly tracks a target’s mobile phone, was responsible for the intrusions. The NSO Group’s software can read text messages and emails and track calls and contacts. It can even record sounds, collect passwords and trace the whereabouts of the phone user.”

If you already have installed iOS 9.4 in an older iPhone or iPad, you need to sync the device with your PC, go to iTunes and install the update.

Alternatively, if you have one of the older devices and have yet to install the OTA version of the update, you can now do so.
