Spam Statistics

Spam is not only annoying, but often also extremely dangerous. Because unsolicited e-mails are and remain one of the most effective vectors for malware. Particularly via large-scale e-mail campaigns, cybercriminals allow their malware to proliferate across the globe in the shortest possible time. Yet e-mails with a previously spied-on target group are also ideally suited even for very specific targeted attacks; after all, practically any device connected to the Internet can be reached and infected with malicious code in this manner. 

The detection systems of the AV-TEST Institute continuously filter and monitor international e-mail traffic. In doing so, among other things, they identify the location of a server through which spam is sent at a specific time. The chart shows the current values recorded over the past two weeks, two months and six months.

In basic terms, international spam campaigns can be divided into three categories: 

a) Unsolicited advertising 
b) Spam with URL (potential phishing or malware)
c) Spam with attached files (potential malware) 

The chart shows the current values recorded for the various spam categories within the past week, the past two weeks and the past month.
