Yeah, this is common in the industry. It's hard to tell them sometimes but that's why you should only use an ATM at a place with 24 hour video surveillance.
That's still not a 100% guarantee but you can also do a quick check of the ATM front, especially if you use all the time, then you'd notice differences.
I understand you can't always tell easily but just use common sense if something looks off with the ATM or the area, don't use the ATM.
