ATM network not very secure

I picked up this issue from Mike Walker blog  where he reports that the US Secret Service is calling the ATM system unsafe after reading this post and the original report from Bob Sullivan's blog.  It Basically amounts the the fact that researchers that work for an Israeli computer security company have released a report in how the ATM network can be compromised in order to reveal PIN numbers.  ATM PIN's are essentially decrypted and encrypted on every network hop so if one machine is compromised it becomes simple to crack the PIN's encryption. And apparently this is some thing the Russian Mob is very interested in.  The Israely company release this report after being dismayed with the American Banks lack of action(Banks were informed of this security flaw in the ATM protocol 2 months before the release of the report.)
