Facebook CEO and Time's Person of the Year Mark Zuckerberg received some private financial consultation on How to raise funds? -- courtesy, a hacker who infiltrated the CEO's fan page.

TechCrunch reported that a hacker left an unusual message stating : 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 Prize winner Muhammad Yunus described it? http://bit.ly/fs6rT3 What do you think? #hackercup2011 appeared on Zuckerberg's fan page.

The message received 1,800 likes and over 500 comments. As a result of the hack, the site has been closed.

The social business concept promoted by the hacker alludes to the microfinance concept developed by Nobel Prize winner Muhammad Yunus and the hacker was courteous enough to give the URL link to the Wikipedia page describing the concept.

The social business refers to the existence of an organization for a non-loss, non-dividend primarily to further a social cause. The returns from the operations are ploughed back into the system to further the reach of the organization.

While it's highly skeptical that the hacker's financial advice was heeded too, since Facebook raised $1.5 billion in an investment round led by Goldman Sachs, the issue of privacy is back to haunt Facebook as it was not able to offer a plausible explanation as to how the hack occurred.

However, Sophos explains that fan sites of celebrities are maintained by a marketing team rather than an individual, due to heavy traffic. Such an arrangement ensures that multiple people have access to the site with different passwords issued to each user. Accounts with multiple passwords are easier to hack as all it requires is one disgruntled employee who is willing to part with the details.

Most recently in December 2010 Facebook was under attack from Tunisian government which gained access to Facebook pages of political protestors. The Atlantic reported that the country's Internet service providers were running a malicious piece of code that was recording users' login information when they went to sites like Facebook. Thus Facebook passwords were stolen right in the midst of the greatest political upheaval in two decades in Tunisia.

Even French president Nicolas Sarkozy's Facebook account was recently hacked and a message was left saying the French president would not seek re-election this year.
