Since last few days, reports about fake AT&T has been circling around. The spam mail has been received my many users worldwide.
The email says the recipient owes a large amount, and many fall into the trap by clicking the link. The link leads to a page hosting the Blackhole exploit kit. Websense reported that about 200,000 fake emails was found.
Note: Spams are increasing per day, some might lead you to some severe attacks, be careful before clicking each link, make sure you are clicking on a trusted link, instead of clicking up links from mails, it is better you manually go to the site.
