The site that was attacked is almost certainly located at 51.86428N 20.92121E (WGS84).

I am surprised to learn from both satellite and street view imagery that this site is located just <50m off a public road (in clear line of sight) and within a residential backyard partly behind the house on the block, and protected by a 1.2-1.5m high white picket fence. To be fair, the lack of almost any visible security deterrent may perhaps scare off an attacker because... security surely wouldn't be that non-existent? My only other thought is these sites really do not matter to Starlink because Starlink will have 1000's of them and as they only process encrypted data, almost anyone can run a ground station for a small reimbursement per month if they've got semi-decent fibre connectivity and a bit of power?
