“Addresses on Intercage’s network range were being used to host command and control channels for botnets,” Mark Sunner, chief security analyst at the messaging security specialist said in a report summary.
Overall, the company’s research group found that the global ratio of spam traffic from previously unknown sources reached 70.1 percent (1 in 1.43 e-mails) of all e-mail in September, a decrease of 8.1 percent compared to the previous month.
In the world of message-based malware threats, MessageLabs reported that over 45 percent of the infection-laden e-mails it filtered represented newly-created attacks. One in 288.1 (0.35 percent) of all e-mails intercepted by the researchers harbored some form of phishing attack during the month. However, compared to other threats including Trojans and botnets, the sheer number of phishing e-mails decreased by 29 percent to 45.7 percent of all message-based attacks tracked in September. Phishing levels for Q3 2008 were at their lowest level since Q2 2006 and have continued to diminish since the beginning of this year, based on the company’s numbers.
