Business email compromise (BEC) ramped up 269% from last quarter to this quarter, according to Mimecast's latest Email Security Risk Assessment (ESRA). This quarter showed a massive spike in emails containing dangerous file types, malware attachments, and spam in target inboxes.

The quarterly report reviewed more than 260 million emails from more than 480,000 users. Of the emails that were scanned by various email security systems and successfully delivered, 28.8 million were spam, 28,808 contained malware attachments, and 28,726 contained dangerous file types.
