Spam is more than 90% of the total, and most Americans seem to come from botnets. New surveys also on the front of malware sites famous and, in particular, social networks are the famous poisoners.
There's nothing more to do with spam we have to deal every day, every time you download your mail.
According to Symantec's monthly report, in May the spam has suffered an increase of 5% since April, reaching 90.4% of the total traffic of e-mail.
Almost 60% of spam comes from botnets known. One in particular, DonBot, delivers 18% of all spam, while the majority of the remainder coming from smaller and unclassified networks of zombies.
It seems that most of the work done in the United States is automated weekdays. On Sunday, however there is a sharp drop in traffic in all regions.
Contrary to what one might expect, the majority of malicious software hidden from the network sites rather famous, and in a particular social network.
The report also highlights how the image-based spam is returning. It is unclear why spammers have decided to resurrect this technique, but in April the spam distributed in this way has touched 22%.
It must be said that there are several discrepancies between the exact percentage of spam. According to Microsoft, it would amount to 97%. Unfortunately, the increase in worms whose purpose is to create huge networks of zombie PCs certainly will not lead to a decrease in spam, but on the contrary tend to increase.
