Finnair AY8 MIA-HEL 6-7 November 2018 flightpath deviation

AY 8 November 7th from MIA to HEL the flightpath deviated at a point north of the Faroe Islands and returned but on a different track than filed. Finnish news reports suggest possible Russian hacking that showed flight paths deviated landings at unscheduled locations. Does anyone have information?

Looking at the flight track, there is a minor heading change to the north of the Faroes, but of only 10 degrees or so degrees to Starboard, nothing exceptional…
