DNS cache poisoning diverts surfers to malicious sites

SANS - Internet Storm Center - Cooperative Cyber Threat Monitor And Alert System - Current Infosec News and Analysis:

DNS cache poisoning involves the practice of hacking into domain name servers and replacing the numeric addresses of legitimate Web sites with the addresses of malicious sites. The scheme typically redirects Internet users to bogus Web pages where they may be asked for sensitive information or have spyware installed on their PCs, an online assault that has also become known as pharming.
In early March, ISC first warned of DNS cache poisoning attacks that were redirecting users to Web sites hosting malicious software, including spyware. The attacks involved several different technologies, including Microsoft server software and security applications made by antivirus specialist Symantec."
