‘Daily number of spam messages in a year’s time with 56 billion decreased’

In a year’s time is the daily amount of spam from 150 billion to 94 billion decreased, claims a security firm. The largest decrease would be due to the tearing down of the Rustock botnet, but also then continued to the amount of drop.

In 2011 there were still about 150 billion spam messages per day sent, according to a survey from security company Commtouch. A year after the take down of the Rustock botnet, is that reduced to 94 billion. That botnet consisted at its peak about 44 billion spam emails per day, according to Symantec when almost half of all spam was. When was the spam volume is still around the hundred billion emails per day. Meanwhile, the other botnets, such as the Bagle botnet, it has increased greatly, but Commtouch does not think that the level is as high as for the take down of Rustock.

The most popular topic for spammers is still the drug industry, especially in Cialis and Viagra are being touted. The second popular category is the trade in namaakmerkspullen. The research also discovered that, in the first four months of this year, porn sites, the most commonly used method for malware to spread. Previously it came up that ‘honour’ to domeinparkeerders. In this first quarter were there for every real mail three spam e-mails sent.

India is still the largest source of spam e-mails; that country is responsible for 19.2 percent of the spam traffic. Gmail, Yahoo and AOL are the domains where almost half of the spam comes from. The researchers have the last data calculated on the basis of the ‘from’field of the spam, which spoofed e-mail addresses here also be added.
