I found this after work :

Dammit, I hate UPS !!!
I never received a call and never called them.
It's too late now to call, I hope that it isn't an other person that is trying to get my miners !
Day 2, Order 7x, Paid 3 June, Received today in France.
Somebody tried to collect my packages at the UPS center.
Fortunately UPS asked for an ID and he just went away. Be careful !
Holy fuck! How the hell could somebody know you were going to receive the miners? Any clue on which was the attack vector? We should rule out that is somebody inside UPS Sweden who knows what's going on and giving the heads up to others..
