Botnet continues massive H1N1 malware campaign
A massive spam campaign that poses as a message from the Centers for Disease Control (CDC) asking people to register for H1N1 vaccinations remains a big problem today, a security researcher said.
The messages lead unwary users to a convincing-looking CDC site where they're asked to create a profile in order to receive a vaccination for the swine flu, which has made headlines for both its aggressive spread and a lack of vaccine. The site urges users to download a vaccination profile archive, and includes a link to that download.
Clicking on the link, however, actually downloads and installs a new variant of the "Zbot" Trojan horse. Called "Zeus" by some security companies, the malware is a bot Trojan that hijacks the Windows PC for nefarious activities, including sending more spam.
