November sees a four-fold increase in the number of daily targeted attacks since January; lowest global spam rate for three years, but Russian spammers continue to innovate in disguising their messages.

The November edition of the Symantec Intelligence report combines the best research and analysis from the Symantec.cloud MessageLabs Intelligence Report and the Symantec State of Spam & Phishing Report. It provides the latest analysis of cyber security threats, trends and insights from the Symantec Intelligence team concerning malware, spam, and other potentially harmful business risks. The data used to compile the analysis for this combined report includes data from October and November 2011.
