Although e-piracy is the primary source of malware, spam continues to be a major contributor to infection and a tool for cyber criminals, according to a report published yesterday by the Finnish company F-Secure.
Experts say the reason why there is so much spam going is that people can not recognize it. Users find it difficult to distinguish real emails from spam, even though spam emails exist over 40.
According to the F-Secure survey, the percentage of users that opens the malicious ones E-mail has increased relative to last year, from 13.4% to 14.2%.
With browsers and operating systems being safer than ever, against exploit kits and vulnerabilities, cybercriminals have turned to spam. "From samples we got and investigated 2018 Spring, 46% of spam emails are dating sites, 23% is email with malicious attachments and 31% contains addresses from malicious or misleading sites," says F-Secure. It is also reported that 85% of the malicious attachments to these files are comprised of the following file types: .ZIP, .DOC, .XLS, .PDF, and .7Z
Spam continues to exist in the same way as it used to be years ago. There has been no change in the way of writing or shipping for years, and this is reflected in their efficiency, which has fallen, even though the email opening rate has risen. The technique is still based on the massive sending of hundreds of millions of emails, in order to "pull" if a tiny percentage of users.
