Even though the overall volume of malware dropped in 2019, phishing and business email compromise went up sharply, according to Trend Micro's 2019 Cloud App Security Roundup.
More than 11 million of the 12.7 million high-risk emails blocked in 2019 were phishing related, making up 89% of all blocked emails.
Phishing emails with an attachment that contained malicious remote templates loaded from remote servers.
For one organization with about 80,000 Office 365 users, Trend Micro Cloud App Security detected over 550,000 high-risk email threats after they passed through Microsoft's native email security filter.
Consider sandbox malware analysis, document exploit detection, and file, email, and web reputation technologies to detect malware hidden in Office 365 and PDF documents.
