How Secure is Your Data On iCloud?

The recent massive iCloud hack on famous Hollywood celebrity devices have left them perplexed with the leak of their private photographs and videos on the internet. The hacker had publicly put them on the internet for the exchange of money.

The happening of the hack raises the concern about the security of the iCloud on Apple devices. Do you use iCloud on your Apple device? How secure do you think it is?

Apple has already talked about the security and privacy of the iCloud in its support portal in the past. Let’s take a look at the security features of Apple’s iCloud in brief.

What Apple Promises About iCloud Data Security?

Apple promises to keep the data secured in the cloud in all times of storage and retrieval. According to Apple, one has to get the authentication tokens to store or retrieve the data to and from the cloud respectively. They also claim to be using 128 bit AES encryption technology to secure data during the dual communication and data transfer process.

There by, Apple summarizes how the data is secured while using various iCloud features. The table is as follows:

Calendars Yes Yes A minimum of 128-bit AES encryption
Contacts Yes Yes
Bookmarks Yes Yes
Reminders Yes Yes
Photos Yes Yes
Documents in the Cloud Yes Yes

Find My Friends Yes Yes
iCloud Keychain Yes Yes
Uses 256-bit AES encryption to store and transmit passwords and credit card information. Also uses elliptic curve asymmetric cryptography and key wrapping. Yes N/A All sessions at are encrypted with SSL. Any data accessed via is encrypted on server as indicated in this table.

What could have happened in case of massive iCloud hack?

Apple security walls were thought to be strong enough to defend against the attacks until yesterday. When it was once found that it could be cracked easily, people started to fear about the security of their personal and sensitive data.

According to Apple, even a third-party application has to communicate through a secured SSL connection to access iCloud data. If it was that secure, what could have happened with Jennifer Lawrence's’ Apple device? Was it the new heartbleed bug again?

I can’t say anything until Apple responds to the massive hack news.
