In an interview with The Wall Street Journal, Tim Cook has promised to improve the security of iCloud following the celebrity photo hacks that have made headlines throughout this week.
Cook said that the accounts of celebrities such as Jennifer Lawrence and Kate Upton were compromised through hackers correctly answering security questions or obtaining passwords through phishing scams. As was established previously, no breach of iCloud occurred to gather the photos.
Under the changes, Apple will now notify users more frequently of security-related matters. Users can expect emails and push notifications when someone logs into their account from a new device, restores an iCloud backup, or changes their password. The new system for these notifications will go live in two weeks' time, and will allow users to change their passwords immediately and notify Apple's security team.
Apple's two-factor authentication system will also be upgraded to cover iCloud. The company acknowledges that not many people use two-factor to protect their accounts, and will more aggressively encourage people to use it in the next version of iOS.
With the new security features, it should be much harder for someone to gain access to private photos without the user knowing. It won't outright prevent access to accounts - you'll still need to be smart with your security online - but it's definitely a step in the right direction.
