Apple has released a “media advisory” as follows, verbatim:

Update to Celebrity Photo Investigation

We wanted to provide an update to our investigation into the theft of photos of certain celebrities. When we learned of the theft, we were outraged and immediately mobilized Apple’s engineers to discover the source. Our customers’ privacy and security are of utmost importance to us. After more than 40 hours of investigation, we have discovered that certain celebrity accounts were compromised by a very targeted attack on user names, passwords and security questions, a practice that has become all too common on the Internet. None of the cases we have investigated has resulted from any breach in any of Apple’s systems including iCloud or Find my iPhone. We are continuing to work with law enforcement to help identify the criminals involved.

To protect against this type of attack, we advise all users to always use a strong password and enable two-step verification. Both of these are addressed on our website at http://support.apple.com/kb/ht4232.

MacDailyNews Note: Apple’s relatively quick response is a good and welcome sign.

Once again:

The problem is that too many people use one password for multiple services. The hackers guess it right once and than have access to all sorts of things: cloud storage, bank accounts, twitter, email, etc.

Regardless of the origination of these photo and videos, social engineering hacks can be thwarted, at least for iCloud. Use two-step verification for Apple ID to keep your personal information as secure as possible. More info here.

As we’ve written before: Always use unique passwords and use Apple’s Keychain Access and iCloud Keychain to create and manage them. When used properly, it works like a dream.
