Lately, it seems that social networking sites like Twitter and Facebook have been receiving viruses directly to its members. It was said that this Friday at 10 pm, that the Twitter site was hacked and defaced.

Twitter.com is said to be down. Some tweets are getting through at the moment because parts of the API are up. The search seems to be working. It is suggested that if you use the same password on your twitter account with other accounts, now would be a good time to change your password on those other accounts.

It was said that there is a history between Iran and Twitter. It was well noted and covered in the media that Twitter was used as a tool during the Iranian election protests. The US government actually intervened to assure that Twitter was available to the protestors in Tehran and around the country. This attack maybe an act of reprisal from groups who were not happy with the role that Twitter played during the protests.

But then, luckily that Twitter.com is back. The company even updated the status blog.
