This is something completely new. I've seen people try to steal ordinary ATMs, but the BTC ATM theft is interesting!
It's the same idea. These guys were probably trying to extract the cash inside the ATM, not private keys to bitcoins. Some of these ATM manufacturers
are incredibly dumb about security, but most of them are probably safe from physical compromise due to encryption.
It looks like they cased out the area pretty well. Nobody noticed the ATM was gone for a week:
Interestingly, the two were so discreet that the theft has not been noticed until a week later. At this point, the police had to call Bitcoin ATM operator and owner Coinme to inform about the theft.
