Some nice slides describing the used cyber kill chain in relatively simple language (I have seen some difficult to understand report aswell):

One of the first steps seems to have been e-mailing MS Office files that requested the use of macros and installed the malware  


After some steps this led to following:

• Supporting attacks:
 Schedule disconnects for UPS systems
 Telephonic floods against at least one oblenergos’ customer support line
• Primary attack: SCADA hijack with malicious operation to open breakers
• Amplifying attacks:
 KillDisk wiping of workstations, servers, and an HMI card inside of an RTU
 Firmware attacks against Serial‐to‐Ethernet devices at substations


A second (known) attack, this time an attack on the transmission system, took place on  December 17, 2016:
