Washington - The hacker gang that looted as much as $1 billion worldwide from banks was unusual: It stole directly from the banks, instead of ripping off their customers.

But this was hardly a bit of Robin Hood banditry that spared innocent account holders. Security experts say consumers still need to keep a close eye on their checking and savings, as epic computer breaches such as this theft - documented in a report issued Monday - are becoming all too common.

The American Bankers Association says there's no evidence that any US bank has been a victim of this particular breach.

But just like other breaches at major retailers or the health insurer Anthem, experts say there are simple protections that consumers can take.
