The cyber-security world is rightly concerned about the potential power hackers could wield if they target a device that is vulnerable to this attack. Apple has released an update to fix security flaws on its iPhone, iPad and Mac devices, which it says hackers may have “actively exploited”. The update has been made available to iPhone 6s and later, iPad Pro, iPad Air 2 and later and iPad 5th gen and later. Apple said hackers used the flaw to infiltrate WebKit, the engine that powers Apple web browser Safari. Which is the most secure operating system if not Apple ?
