Cyberattacks Looking More Like Legitimate Traffic

According to Cisco's recently released annual report, there was a 90 percent increase in cyberattacks originating from legitimate domains during 2008.

The following are some other highlights of the report:

• Spam accounts for nearly 200 billion messages each day, which is approximately 90 percent of email sent worldwide
• The overall number of disclosed vulnerabilities grew by 11.5 percent over 2007
• Vulnerabilities in virtualization products tripled to 103 in 2008 from 35 in 2007, as more organizations embraced virtualization technologies to increase cost-efficiency and productivity
• Over the course of 2008, Cisco saw a 90 percent growth rate in threats originating from legitimate domains; nearly double what the company saw in 2007
• Spam due to email reputation hijacking from the top three webmail providers accounted for just under 1 percent of all spam worldwide, but constituted 7.6 percent of all these providers' mail
