10 Naked Celebrity Phone Hacks - Slideshow

Scarlett Johansson............... VIEW NEXT SLIDE-->
NEW YORK ( MainStreet) -- Scarlett Johansson's leaked nude photos may be grabbing headlines, but rumors of her being hacked began to surface back in March, associated with the hacker ring believed to be behind 50 or so similar celebrity exploits.

The group, calling itself Hollywood Leaks, even posted a YouTube video and since-deleted Twitter feed to brag about their conquests.

The mission statement issued by the group, riddled with anti-Semitic and homophobic language, includes the following:

"Attention Hollywood. We are Anonymous. We have been watching you. We have been listening to you. You have been allowed to run free too long. The time of Jew-controlled media is over. We are taking back the media with your gay slur vampires and Scientology pastors. We are here for the people. We are here for the Lulz. We are here to stay. We have your lives. We have your blood, sweat and tears. Over the next couple of weeks, everyone will have them. We will rock you for ages. Consider this our acceptance speech for the Video Music Awards."

Paris Hilton............... VIEW NEXT SLIDE-->

The heiress Hilton has been a gift that keeps on giving for the prying eyes of the Internet.

For years, various images of her in compromising positions -- from a sex tape, to paparazzi-captured wardrobe malfunctions -- have gone viral. In 2005, her T-Mobile Sidekick (remember those?) was plundered and her entire contact list, including the phone numbers and email addresses for a variety of other celebrities, was posted online. The hacker, a Massachusetts teen, was later tracked down and confessed to the deed, getting 11 months' detention in a juvenile facility

Blake Lively............... VIEW NEXT SLIDE-->
Like many of the celebrities with leaked photos, the Gossip Girl star struck an all-too common pose -- an iPhone in one hand while making use of a nearby mirror.

At least the assumption on the Internet was that it was Lively striking the raised-arm pose. Her reps have maintained that the pictures, which began flowing through cyberspace over the summer, are not her.

The response, as least from one hacker who posted on a message board: "Oh, yes, Blake's rep. These are totally fake. We really, really believe you. Want moar?" (If you think that's a typo, you're over 30, not spending enough time online or both.)

And, sure enough, additional pictures of a person who may or may not be named Blake followed.

Anthony Weiner............... VIEW NEXT SLIDE-->
The disgraced congressman with an unfortunately appropriate name was not among the victims of the hacker ring claiming responsibility for the onslaught of new celebrity skin.

We had to mention him, however, for a reminder of his sheepish excuse when his unique way of polling the electorate was exposed: He initially explained it away as the work of hackers. As media scrutiny intensified, the New York Democrat was left fumbling for an excuse as to why he never made good on his threat to have police or the FBI investigate the security breach.

Mila Kunis & Justin Timberlake..... NEXT SLIDE-->
Kunis, a rising star who has gone from That '70s Show and the voice of Family Guy's Meg Griffin to an acclaimed performance in Black Swan, may have been more than just a recent co-star of Justin Timberlake.

Along with a shot of the actress in a bathtub, a pilfered snapshot shows Timberlake bringing SexyBack with a pair of pink panties on his head.

Fortunately for the frequent SNL host, there were no additional shots of him re-enacting his famous skit/viral video involving a box.

Vanessa Hudgens............... VIEW NEXT SLIDE-->
Hudgens, star of Disney's ( DIS) High School Musical trilogy, has been a popular target for hackers.

A selection of pictures and videos, believed to have been snagged from her Gmail account, have caught the attention of FBI investigators.

Miley Cyrus............... VIEW NEXT SLIDE-->
Various sites on the Internet once had "countdown clocks" in anticipation of singer/actress/Disney princess Miley Cyrus' 18th birthday -- the assumption being that upon being "legal," nude photos were inevitable.

They didn't have to wait long. In recent months, there have been a variety of paparazzi shots showing more than just what was under Hannah Montana's blonde wig. There has also been a regular infusion of allegedly stolen pictures.

Some of the claimed hacks are probably not even Cyrus. Others, however, may indicate that a Party in the U.S.A. involves wet, white T-shirts and plenty of self-shots in underwear. It's enough to cause a dad an achy, breaky heart.

Demi Lovato............... VIEW NEXT SLIDE-->
Aside from Miley Cyrus and Vanessa Hudgens, a variety of other Disney Channel stars are rumored to have been targeted by the latest batch of celebrity hacks.

Demi Lovato, who starred in the sitcom Sonny With a Chance before entering rehab, is among those rumored to have had her phone or Twitter account compromised.

Selena Gomez (star of Wizards of Waverly Place and current Justin Bieber arm candy) may be another victim, according to rumors.

A video that recently made the rounds showed a hacker guiding viewers step by step as he hacked into Gomez' Facebook account (he claimed to have done so for "educational purposes" with no intention of stealing from the page or altering it). Her Twitter account had also been the successful target of another hacker, who posted "Oh Yeh, JUSTIN BIEBER SUCKS!" as a fake official message.

Christina Aguilera............... VIEW NEXT SLIDE-->
Once upon a time, Christina Aguilera was no stranger to showing a little skin, notably in a racy spread for Maxim magazine and the aptly named video for the song Dirrty.

Her recent stab at mainstream respectability, as a judge on the hit NBC competition The Voice, makes the fresh leaks of the songbird's private poses a bit more embarrassing -- especially given her choice of a provocative bondage theme.

Jessica Alba
Apparently snared by the same hacker collective that targeted Johansson, the purloined image of Alba is less posed than others that were uncovered.

Her camera phone captured more of a Girls Gone Wild vibe with her flashing a single exposed breast.

Unlike the other victims, Alba may have the added blessing of being smart enough not to include her face in the shot.

More Details on the Hacking Scandals

Scarlett Johansson nude photos were enough to send half the pubescent online community on a multiday scavenger hunt, but they're also a reminder of how easily hackers can access information of personal devices.

Naked photos of Johansson, Mila Kunis, Justin Timberlake, Blake Lively and others scored by hackers got the attention of the FBI, but PC, smartphone, tablet and even game console users and producers have been slow to learn from celebrities' misfortunes. Michael Gregg, chief operating officer of Houston-based Superior Solutions, says many users' information and devices are vulnerable because they've been lax in securing them.

"Generally these types of attacks require someone to get physical access to the phone the photos were stored on," Gregg says. "However, there is a much greater chance that the photos were accessed from the users online account or from an vulnerable email account."

Gregg points to the hacking of former Alaska Gov. Sarah Palin's Yahoo ( YHOO) email account during her vice presidential bid in 2008 as a prime example of people in high places making online security a low priority. Though nude photos weren't involved, the lessons are the same: A weak password or a local system hacked with a virus that logs keystrokes can give hackers access to photos, documents, passwords or any other information stored in an email account.

Not that the devices themselves are all that secure. In November, TechCrunch discovered that the Apple ( AAPL) iPhone photo-sharing app Instagram sent user passwords over the air in plain text, giving hackers potentially unfettered access to user photos. Instagram's developers fixed the leak with an update.

In February, a North Carolina University professor warned that a major security bug in Google ( GOOG) Android 2.3 gave hackers and malicious websites access to the contents of a user's microSD card and the voicemails, photos and online banking information therein. More recently in March, Research In Motion ( RIMM) advised its Blackberry smartphone users to disable Javascript after it was discovered a vulnerability in its browser could give hackers access to the device's photos, contact list and Blackberry Messenger conversations and data.

Johansson and her celebrity friends are just like any other American when it comes to shrugging off online and device security. In a survey of online shoppers by online security firm Symantec ( SYMC), for example, 97% of respondents said they were either somewhat or extremely knowledgeable about online security. Of that, 80% even said they knew to look for the padlock icon indicating Secure Sockets Layer encryption while visiting e-commerce sites. That's only valuable if online shoppers heed the precaution, though, which only 55% of those padlock seekers say they do by aborting unsafe transactions.

Companies also haven't exactly been swift on the uptake. A survey by device-centric security company Mocana survey found that 64% of employees at firms including Apple, AT&T ( T), Intel ( INTC) and IBM ( IBM) had an attack on a non-PC device requiring the attention of their IT staff. Another 54% said that attack disrupted the company's network, but 51% said their companies still didn't update security or create patches to protect information on devices. That's bad news for companies and their data, but as televisions, game consoles and other home devices get connected and more information goes into the cloud, it's equally worrisome for the average consumer -- and the less-than-average celebrity.

"There are two major threats: someone or something trying to break into a device to steal data or insider threats where the handsets are getting way more powerful and have sensitive data on them and access to the back-end system," says Adrian Turner, chief executive of Mocana. "These devices are connecting to each other over networks, and once you can get access to a device on the network, it's a lot easier to get access to the whole network. We think it is a concern, and that the way to solve it is to get software on the device and to find solutions in silicon."

As a public service to those who still have that topless pic on their cellphone after sending it as a "present" last Valentine's Day or that down-the-shorts shot you thought was hilarious at spring break two years ago, we compiled the following list of notable names who've recently exposed more of themselves to hackers than they'd bargained for. Let the panic deleting commence:
