Symantec reports spam volume fell by 47 percent from August to October thanks to the bust-up of spam gangs and the unplugging of the Bredolab botnet. Unfortunately, spam still comprised 86.6 percent of all messages in October, and some more bad news is that phishing attacks are on the rise.
So says a new study released Thursday by Symantec, which found that spam comprised 86.6% of all messages in October, compared with 89.4% in September. Symantec said the decline continues a "sharp decrease in global spam volume," with spam volume down a whopping 47% from August to October. That's the lowest volume of spam seen since September 2009.
What's behind this welcome decrease in spam? Chalk it up to the bust-up of multiple Zeus-using gangs in recent months, the spamit.com shutdown, as well as Dutch authorities essentially unplugging the Bredolab botnet, said Symantec.
