For September 2010, spam comprised 89.4% of all email, down from 92.5% in August, according to a new report from Symantec. The September total was the lowest level since 2008, when rogue ISP McColo was shut down. Phishing jumped by 52% in September from the month before.
"This [phishing increase] was primarily due to an increase in both automated toolkit attacks and unique phishing websites," said Symantec. Meanwhile, the number of phishing websites -- generated by automatic toolkits -- increased by 46%, unique URLs increased by 83% and phishing websites with all-numeric IP domains -- such as -- rose by roughly 35%.
