Analysis of half-a-billion emails reveals malware-less email attacks are on the rise

FireEye analyzed over half-a-billion emails from 1H 2018, and found that 32% of email traffic seen in the first half of 2018 was considered ‘clean’ and actually delivered to an inbox. Their report also found that 1 in every 101 emails had malicious intent. When compared to the previous six-month period, the changes depict that email-based threats keep increasing.

With email security solutions focused on detecting malware, cyber criminals are now adapting their attacks, exposing organizations to malware-less assaults such as CEO fraud. The majority of attacks blocked (90%) during analysis were malware-less. Phishing attacks alone made up 81% of the blocked malware-less emails, almost doubling from January to June 2018.
