Analysis of the documents is still pending (please check back), although the payload is almost definitely the Dridex banking trojan.
The Hybrid Analysis of the two documents   shows attempted downloads from the following locations:
bhairavraffia.com/8i65h4g53/o97i76u54.exe [file not found]
This binary has a detection rate of 1/54 and those reports indicate malicious network traffic to the familiar IP address of:
184.108.40.206 (Ministry of Education, Thailand)
I strongly recommend that you block traffic to that IP.
