I'd like to hear what everyone knows about security holes in bank machines. I don't believe in that little bank machine cracker they used in Terminator 2, but I'm interested in the algorithms and protocols the ABM uses to communicate w/ the home bank. My bank says they have some special chip inside the ABM to secure the transfer, and that's all they told me. I also heard that the magnetic stripe on the back contains your card number (the shiny metallized numbers on the front) encrypted using DES using your PIN as the key. Way out to lunch? Too close for comfort? Any knowledge...heck, even rumors.... would be appreciated. That way we can see what kind of FUD is out there. My bet is that the magstrip with DES'd card number on it theory is FUD. But my bank did say that there were some fraudulent transfers (read successful hits) in Europe. I bank with Alberta Treasury Branches, and they said their hardware is immune to the attack that was performed in Europe.... I will have to dig a bit on that one. Anyway, I hope I hear something from all of you soon... -- Chris Kuethe <ckuethe@gpu.srv.ualberta.ca> LPGV Electronics and Controls http://www.ualberta.ca/~ckuethe/ RSA in 2 lines of PERL: http://www.dcs.ex.ac.uk/~aba/rsa/ print pack"C*",split/\D+/,`echo "16iII*o\U@{$/=$z;[(pop,pop,unpack"H*",<> )]}\EsMsKsN0[lN*1lK[d2%Sa2/d0<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<J]dsJxp"|dc`
