So, how can we protect ourselves?
1. Assume that your passwords are rubbish
The vast majority are; we're what, two decades or so into a digital revolution and we're still securing personal data with cryptographically laughable strings such as "123456" or "Arsenal1". If there's a recognisable word in there, make it unrecognisable. If it's 8 letters long, make it 12 letters long. If it has the number "69" in it, change it. If you use the same password on multiple sites, use a tiny amount of ingenuity to avoid doing so. It's really not difficult. If you think it is, use a password manager.
2. If you're a public figure, take extra care
Don't secure your online accounts with questions such as "What was the name of your first school" if the answer is freely available on Wikipedia. You may as well use your own name as your password.
3. Learn to use your device
It probably didn't come with a manual - they barely ever do - but even if it had, you probably wouldn't have read it. Understand what data goes where. If an app offers you "convenience" or "peace of mind" or "seamless back-ups" or "worry-free operation", don't necessarily be reassured. Take a moment to think about where your stuff is ending up. If it's the cloud, its physical location may be in a data centre on the other side of the world.
If your passwords are strong enough, that's probably fine, but at least be informed. We're being let down by technology because we don't understand it. Absorbing enough knowledge to make decisions is a good thing.
4. Don't be lazy
There's a thing called 2-Factor Authentication which offers an additional layer of security online. iCloud (the Apple service being blamed for the leak) offers it as an option. Google services do. Paypal does. Use them. Yes, it might conceivably add 10 seconds to your log-in time. Your convenience will be marginally affected, but in the grand scheme of things it's really not a big deal.
5. Ignore anyone who sternly tells you not to use the cloud
It's virtually impossible. All major email services use it. Incredibly useful back-up services such as Dropbox, Google Drive or OneDrive use it. We're stuck with it. Make the most of its power by bearing in mind steps 1-4.
6. Ignore those who tell you not to take nude pictures of yourself
Don't deny your innermost feelings. Do what you blimmin' well like. Feel free to succumb to sexual thrill and experience excitement. It's fine. Just do so while bearing in mind steps 1-4.

7. Ignore anyone who tells you that it's your fault for being famous...
...or a woman, or for making a film that wasn't up to scratch, or for somehow managing to antagonise a bunch of tragic sociopaths who can only derive meaning from their lives by making the lives of others completely miserable. It's not you, it's them. Deny them their pathetic pleasures by bearing in mind steps 1-4.
