And, reading between the lines, that right there is possibly your biggest clue. Beyond the juvenile intrigue of someone breaking something just to see if they can, or even some chintzy politically motivated anti-propaganda operation, another motive might lie in assisting/disrupting (depending on whose side your on) clandestine operations in a specific geographic area.

It's tempting to wonder if maybe it's just some Greek crypto-anarchists horsing around, but more likely it'd be someone with heavy-weight resources and know-how like CIA/GRU agents operating in Syria.

I think you hit the nail on the head. This is very interesting in light of Turkey intercepting "radar" equipment from Russia to Syria.
