[by:www.21voa.com] [00:00.00]¸ü¶àÌýÁ¦Çë·ÃÎÊ21VOA.COM [00:00.12]Even Facebook founder Mark Zuckerberg is not safe from cyber attackers. [00:08.12]Zuckerberg's Twitter, LinkedIn and Pinterest profiles [00:13.28]were briefly hacked over the weekend. [00:16.56]His Facebook and Instagram accounts were not involved, Facebook officials said. [00:23.16]A group calling itself OurMine Team said it attacked the three accounts on Sunday, [00:31.56]according to the website TechCrunch. [00:34.64]The accounts were quickly restored. [00:39.56]Twitter says a Twitter account used by the hackers to post messages was suspended. [00:47.32]A website called Engadget captured messages posted by the hackers [00:54.12]to Zuckerberg's personal Twitter account. [00:58.25]"We are just testing your security," [01:01.84]said one message posted by the hackers to the billionaire's Twitter profile. [01:08.16]Zuckerberg had not posted anything to his Twitter account since 2012. [01:15.56]Business networking site LinkedIn confirmed Monday [01:21.96]that the Facebook founder's data was compromised, The New York Times reported. [01:29.16]The company said the hackers attempted to create a false profile for Zuckerberg. [01:36.76]"We were alerted of this takeover attempt [01:40.36]and have taken action to remove the false profile on LinkedIn," [01:46.08]said a statement, the newspaper reported. [01:49.16]The hackers also posted what they claimed was the password [01:54.64]used for Zuckerberg's LinkedIn account. [01:59.20]But LinkedIn did not say if the attacks on Zuckerberg's social media accounts [02:05.80]were part of a large data breach at the company in 2012. [02:11.64]That leak, of emails and passwords, affected more than 100 million LinkedIn accounts. [02:21.12]Internet security experts suggest that users [02:25.88]change their passwords often to keep accounts safe. [02:30.36]They also warn users not to use the same passwords [02:35.24]for different social media accounts. [02:38.52]I'm Bryan Lynn.
