Malicious hackers are using fake alerts around H1N1 (Swine Flu) vaccines to trick end users into installing malware on Windows computers. The latest malware campaign begins with e-mail messages offering information regarding the H1n1 vaccination. The messages contain a link to a bogus Centers for Disease Control and Prevention site with prompts to create a user profile. During this process, a malware file gets planted on the user s machine. Messages are being received at a rate of 18,000 per minute, more than one million per hour.
