In light of the recent hacking that led to the theft of a number of celebraties’ private photos, Apple says it’s beefing up secrurity around its iCloud platform. 

Apple CEO Tim Cook told the Wall Street Journal Friday that Apple would be looking at additional security measures to protect information stored on iCloud, but he also highlighted the need for end users to be more vigilant around security. 

Apple will reportedly begin sending alerts via push notification and email when someone tries to change an account password, restore iCloud data to a new device, or when a device logs into an account for the first time. 

While Apple maintains that its iCloud has not been hacked, the company did admit in a statement on its website that “certain celebrity accounts were compromised by a very targeted attack on user names, passwords and security questions.” 

Cook said that part of the problem is that users have a lax attitude towards security, using easily hackable passwords and security questions. He said awareness needs to be raised around how best to protect data. 

Apple said that none of the cases it investigated had resulted from any breach in its systems, including iCloud, or Find my iPhone, but theat it is continuing to work with law enforcement to help identify the criminals involved. 

On its website, Apple notes that to protect attack, the company advises all users to always use a strong password and enable two-step verification.
