Zuckerberg's page was hacked on Tuesday.
The message that appeared on Zuckerberg's page under his name read: "Let the hacking begin: If Facebook needs money, instead of going to the banks, why doesn't Facebook let its users invest in Facebook in a social way? Why not transform Facebook into a 'social business' the way Nobel Price winner Muhammad Yunus described it? http://bit.ly/fs6rT3 What do you think? #hackercup2011?"
The message received more than 1,800 "likes" before it was removed from the page, CNN reported.
Recently, French President Nicholas Sarkozy had his Facebook account hacked as well. A message on his wall said that he would not seek re-election.
"A key part of controlling information has always been protecting it from security threats like viruses, malware and hackers. That's why we've developed a number of complex systems that operate behind the scenes to keep you secure on Facebook," the blog entry posted Wednesday said.
