As email remains to be a common infection vector because of how easily it can be abused, attackers continue to take advantage of it by crafting threats that are persistent in nature and massive in number. In 2018 alone, the Trend Micro™ Cloud App Security™ solution blocked 8.9 million high-risk email threats after Office 365’s built-in security. The vulnerable nature of email is further evidenced in a new Avanan report, which found that of 546,247 phishing attacks deployed against Office 365, 25% were able to bypass its security.

The report looked into 55.5 million emails sent to Office 365 and G Suite and found that one in every 99 emails is a phishing attack. In the report’s breakdown of phishing attacks, malware phishing or the use of a phishing email to install malware on the victim’s device accounted for 50.7%, credential harvesting 40.9%, extortion 8%, and spear phishing 0.4 %.
