Yesterday Facebook CEO Mark Zuckerberg's twitter and Pinterest acoount have been allegedly hacked. Later, Zuckerberg's Twitter and Pinterest accounts were compromised over the weekend, according to a report on Sunday from technology news website. Those accounts have since been "re-secured using best practices," a Facebook spokesman told media, adding, "no Facebook systems or accounts were accessed." Zuckerberg's Twitter account, @finkd, last used in January 2012, posted a tweet on Sunday with the message, "Hey, @finkd You were in LinkedIn Datatbase with the password 'dadada' ! DM (direct message) for proof," according to a screenshot posted to Twitter by Ben Hall (@Ben_Hall), founder of Katacoda, an interactive learning platform for software developers. The tweet appeared to ask Zuckerberg to contact the sender, who claimed to have accessed his account. "Hey , we are just testing your security ,please dm (direct message) us for contact! twitter: twitter.com/_OurMine_," the compromised page said in a message that seemingly identified the hackers as being associated with the linked Twitter account.
