In Terminator II, it was the Atari Portfolio that hacked ATMs. In Brazil, it is the Asus Eee.
Scallywags damaged the nearby cash machines to funnel passers-by to their rigged one, into which was stuffed a subnotebook and all the accouterments required to steal card numbers and customer details. High-tech, yes, but hardly ingenious, given that they didn't do anything to hide their own identities from nearby closed-circuit cameras.
Globo reports that the thieves, arrested in Rio Grande do Sul, are members of a card-cloning gang. They were caught when the bank manager looked at security tapes–from the original story, it appears he simply found it a little odd that the bank was ransacked and most of the ATMs rendered nonoperational during the night.
