Facebook's constant site improvement has recently attracted a lot more cybercriminals to take advantage of and exploit the social networking site for malicious intent.

The new profile page also contains a quick summary of user's information that can be viewed in top of the page.
Two days after the new profile rollout, spammed messages allegedly coming from Facebook were found informing its recipient to download a Facebook toolbar, purportedly intended to make it easier for users to share and connect with friends. The spammer even used the Facebook template to make their email seem legitimate. It contains a 'Download Here' button that redirects to a website that automatically downloads an EXE file, fb.exe.
