Proofpoint Threat Operations and Research recently published their quarterly threat report for July - September 2016, which includes key findings such as: 

• Volume of malicious emails rose to their highest levels ever
  New campaigns bearing varied attachment types broke volume records set in Q2, peaking at hundreds of millions of messages per day. JavaScript attachments continued to lead these very large email campaigns, growing 69% this quarter.

• Ransomware variants grew tenfold
  In particular, 97% of messages with malicious document attachments featured the popular ransomware strain Locky, while CryptXXX was the dominant ransomware delivered by exploit kit (EK).

• Threat actors adjusted tactics in business email compromise (BEC) attacks
  In BEC attacks, “display-name spoofing” increased to almost 1-in-3 BEC messages, gaining ground on instances of “reply-to spoofing,” suggesting that BEC actors continue to adjust techniques.
