A spokesman at Go Daddy, the popular domain registrar and Web host company, believes some of its users may have been phished. Attackers placed malicious DNS records on some of the company s domain names to redirect users to sites hosting the Cool Exploit Kit, a kit known for dropping the Reveton ransomware. Go Daddy is expiring the passwords of those affected to prevent the further spread of malware. In September millions of sites hosted by Go Daddy were knocked offline in what was thought to be a massive distributed denial of service (DDoS) attack.
