A new large-scale botnet has been spotted forwarding what appears to be real news headlines about Microsoft, George Bush and Al Qaeda in an attempt to infect users. Security vendor Marshal is warning that a growing large-scale botnet – called Rustock - is forwarding spam containing exploitive headlines in an attempt to infect users and grow its network.

Numerous small businesses and private web sites - so far predominantly in US and China - have been targeted in the campaign, claimed Marshal. The security vendor warned a variety of headlines are being used to lure victims into clicking on a malicious link.
