San Francisco-- Facebook CEO Mark Zuckerberg, whose company prides itself in hacking, has been the target of a hacker.
A Palestinian man posted a message on Zuckerberg's page last week after he said repeated attempts were made to report the security hole on the social-networking site.
"First, sorry for breaking your privacy and post(ing) to your wall, I (had) no other choice to make after all the reports I sent to (the) Facebook team," Khalil Shreateh wrote on Zuckerberg's wall.
Shreateh is a self-described unemployed security researcher. Shreateh posted a series of email exchanges he said were between him and Facebook's security team.
The Palestinian researcher said he discovered a security hole allowing him to post to any members page.
Facebook's security team, which awards cash to so-called white hat hackers that report flaws, said the reports from Shreateh were unclear amid the hundreds of daily reports it receives.
"Had he included the video initially, we would have caught this much more quickly," wrote Matt Jones, a member of Facebook's security team, on YCombinator's Hacker News.
Facebook is located in Menlo Park, Calif., on an office park whose street is named Hacker Way. The company posted a hacker manifesto of sorts in its preliminary prospectus outlining its company.
Facebook fixed the flaw on Thursday.
