Pshhh, what nudes? Taylor Swift's social media accounts were hijacked on Tuesday, Jan. 27, by so-called elite hackers who threatened to release nude photos of the pop superstar in exchange for bitcoins. Swift, however, retorted that there were no naked pics and told the offenders to "have fun" finding any. 
 
 The story began early Tuesday when several updates were tweeted from Swift's accounts, instructing her 50 million-plus fans to follow two specific members of the Lizard Squad, @lizzard and @veriuser.

 The Lizard Squad is a group of hackers who claimed they were behind North Korea's Internet shutdown amidst the Sony leak scandal. Over the holidays, the same group apparently took down the entire PlayStation and Xbox Live gaming networks. They were also reportedly responsible for Monday evening's temporary Facebook and Instagram issues. 
 
 Someone from Swift's team promptly deleted the tweets, but the hackers claimed that they had access to nude photos of the 1989 hitmaker (via The Verge). The accounts @lizzard and @veruser were suspended by Twitter as of Tuesday afternoon.

 Swift, 25, meanwhile, took to her Tumblr to address the hacking. "My twitter got hacked but don't worry," she wrote to fans. "Twitter is deleting the hacker tweets and locking my account until they can figure out how this happened and get me new passwords. Never a dull moment." 
 
 After her account was unlocked, Swift responded to the intrusion with several lighthearted tweet.

 The "Blank Space" singer also used her Tumblr on Tuesday to write a sweet message to a bullied fan named Caillou. 
 
 "I was really shocked to hear you say that you'd been bullied because of your name because the first thing I thought when I saw it was 'woah, Caillou is such a cool name,'" she wrote. "Honestly. I thought it was so cool because it's different, and herein lies our issue: you will always be criticized and teased and bullied for things that make you different, but usually those things will be what set you apart." 
 
 She continued: "No one gets to have a place in your mind if they weren't invited there by you. So please do me this one favor: Don't let their ugly words into your beautiful mind." Read what she wrote to her bullies on Tumblr. 
 
 Swift is currently in Hawaii on a trip with the Haim sisters.

 Twitter’s top user and pop superstar Katy Perry was hacked on Monday, with her account sending abusive tweets to her 89 million followers and reportedly leaking an unreleased song. 
 
 The tweets removed from Perry’s account page, the most followed on Twitter, beating Justin Bieber and Taylor Swift, sent homophobic messages to users and a “miss u baby�? message to the singer’s arch rival Taylor Swift among others. 
 
 The hacked account signed off with a tweet telling users to “haha follow @sw4ylol #hackersgonnahack�?, who appears to have claimed responsibility for the hack. 
 
 Court refuses request to force alleged hacker to divulge passwords Read more 
 
 @sw4ylol, the alleged hacker’s account, which is still operational but appears to be caught in a semi-suspended state pushing out tweet notifications for tweets that don’t appear, also reportedly shared an unreleased track from Perry on SoundCloud and a screenshot of the singer’s email account. 
 
 The link to the SoundCloud file shared by a user named “slut�? was removed from Twitter, along with several other tweets from the account. The alleged hacker’s account still shows a takedown notification from SoundCloud for Witness 1.3, after the song was removed from the service. 
 
 Perry’s account has been cleaned of the hacked messages, but has yet to acknowledge the intrusion. ||||| (CNN) -- A publicist for Jennifer Lawrence slammed the appearance of nude photographs of the Oscar-winning actress online Sunday as a "flagrant violation of privacy." 
 
 "The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence," the publicist said in a written statement. 
 
 Posts on 4chan, Reddit, Twitter and Tumblr claim to include nude photographs of Lawrence, who won an Academy Award last year for her role in "Silver Linings Playbook." 
 
 Twitter posts on verified accounts of several other celebrities Sunday also reported hacks. 
 
 "To those of you looking at photos I took with my husband years ago in the privacy of our home, hope you feel great about yourselves," actress Mary E. Winstead wrote. 
 
 "Knowing those photos were deleted long ago, I can only imagine the creepy effort that went into this. Feeling for everyone who got hacked." 
 
 Some celebrities claimed the photos were doctored. 
 
 An individual close to singer Ariana Grande told CNN photos claiming to show her are "completely fake." 
 
 And actress Victoria Justice said pictures purporting to be her are fake. 
 
 This isn't the first time celebrities have accused hackers of stealing risque photos. 
 
 A judge sentenced Christopher Chaney of Florida to 10 years in federal prison in 2012 for stealing nude photos, scripts and personal information from the e-mail accounts of 50 entertainment industry figures, including movie stars Scarlett Johansson and Mila Kunis and singer Christina Aguilera. 
 
 The first real case of a celebrity hacking attack was in 2005 when hackers logged into Paris Hilton's phone and stole photos of the reality star, Mikko Hypponen, chief research officer at computer security company F-Secure told CNN in 2011. Those hackers reportedly were able to break into Hilton's phone by correctly guessing the not-so-secret answer to her security question, which was "tinkerbell," the name of her pet Chihuahua. 
 
 CNN's Rachel Wells, Dave Alsup, Alan Duke and John D. Sutter contributed to this report. ||||| Something to roar about. Katy Perry is just the latest celebrity to get hacked on social media. A jokester hacked into her Twitter account on Monday, May 30, and sent direct comments to other users — including Taylor Swift. 
 
 "miss u baby @taylorswift13," the user wrote, pretending to be Perry, 31. Many fans of the "California Gurls" singer liked and retweeted the comment, but quickly figured out that it was a hoax. 
 
 Perry and Swift, of course, haven't been on good terms in quite some time. The former pals, who both dated John Mayer, first feuded in 2014 when Perry allegedly hired some of Swift's backup dancers. 
 
 "She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me," Swift, 26, told Rolling Stone of an unnamed pop star rival in September 2014. (Insiders exclusively revealed to Us Weekly in September 2014 that Swift's hit "Bad Blood" is about Perry.) 
 
 "For years, I was never sure if we were friends or not," she added. "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?' [Then last year] she did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy!" (In response, Perry referenced the character Regina George from the 2004 comedy Mean Girls.) 
 
 
 
 The prankster didn't just contact Swift on Monday, though. The unidentified person sent out a derogatory message to #DramaAlert website creator DJ Keemstar (real name: Daniel Keem) and tagged the Twitter handle @sw4ylol. It appears that @sw4ylol might be the one behind the hack. 
 
 "haha follow @sw4ylol #hackersgonnahack," the hacker posted on Perry's page on Monday. The @sw4ylol account, which lists its location as Romania, tweeted: "Who TF is Katy Perry." Perry's fake tweets have since been deleted.

 Back in August, Motherboard's Joseph Cox reported that 200 million apparent Yahoo user credentials were being sold on the dark web. At the time, the company's response was only that it was "aware of [the] claim." 
 
 But now Kara Swisher, one of the tech industry's most respected journalists, is reporting for Recode that Yahoo sources tell her the company is preparing to publicly confirm the hack. (Her sources did not confirm its exact size, only that it was "widespread and serious.") 
 
 Yahoo did not immediately respond to Business Insider's request for comment. 
 
 Motherboard was told by the hacker who held the data (and was selling it for 3 bitcoins, worth $1,860 at the time) that the breach was carried out in 2012 — and was never made public. Data included usernames, encrypted passwords, date-of-births, and some email addresses. 
 
 A spate of historic data breaches affecting millions of users have recently been coming to light, affecting companies including LinkedIn, MySpace, and Tumblr. If user passwords are unencrypted (or not encrypted properly), hackers can then use this login data to break into individual user accounts — and often, because people reuse passwords across multiple sites, the hackers can use the information to break into accounts on other sites as well. 
 
 We saw multiple high-profile demonstrations of this problem this summer, as celebrities and public figures including Mark Zuckerberg and Drake had their Twitter accounts broken into. Twitter wasn't hacked — but the victims had reused passwords that were also used on hacked websites. 
 
 This new attention on the alleged breach comes at an awkward time for Yahoo. The tech company is selling its core business to Verizon for $4.8 billion (£3.7 billion) after years of flagging fortunes. 
 
 There's nothing ordinary users can do to prevent these kinds of breaches, but using a strong, unique password on each website or service you have an account on (managing those passwords with a password-manager app if necessary) will help limit the damage.
– Apparently there is at least one celebrity who doesn't take nude pictures: Taylor Swift. Her social media accounts were hacked yesterday by the Lizard Squad, a group that's claimed responsibility for a number of other recent cyberattacks. The group threatened to release nude photos of Swift, but she was having none of the nonsense, Us reports: "any hackers saying they have 'nudes'? Psssh you'd love that wouldn't you! Have fun photoshopping cause you got NOTHING," she tweeted, along with a play off her latest hit: "Cause the hackers gonna hack, hack, hack, hack, hack..." On Tumblr, she assured fans, "My Twitter got hacked but don’t worry, Twitter is deleting the hacker tweets and locking my account until they can figure out how this happened and get me new passwords." She later continued making it difficult for you to hate her by responding, to a fan who had requested that someone tell her to get off Tumblr and do her homework, "Get off Tumblr and do your homework, Destiny." (Swift recently revealed her bellybutton for the first time.)
