Interesting
Whichever side of the conflict you back (if any at all), I do find it quite interesting. Possibly a first example of "cyberwar" being waged. Not on its own, but as a tactic directed against a military force as part of a wider military operation. It was malware, targeting a specific app only useful to people manning artillery, which provided very useful location data for where the artillery would be (the app is being run by an artilleryman when they ware using artillery, pretty clear cut case of a valid military target).
The military has been talking about "cyberwar" for years now, but it always seemed like some undefined nebulous concept. So far all battles so far have been with one technologically advanced side against another less technologically advanced, so any "cyberwar" involved mostly script kiddies defacing the other sides sites, the odd DDOS, and spreading propaganda.
Here we see it applied between two "advanced" opponents, with a direct military benefit for one side due to an exploit used against the other. I wonder if in future they will limit soldiers access and use of smartphones. They are basically mini spies in your pocket, even when not compromised.
Up until now the closest we had was stuxnet, however that was more disrupting enemy industry in peacetime, than what I would call an active war.
