POS
The funny thing is that now that EMV cards have been introduced and more stores are taking them, there is a lot of futzing about at points of sale as cashiers attempt to educate consumers on how to insert their new chip card into the new system.

This could make it easier for a bad guy to insert a skimmer into a POS device (and yes, even EMV is vulnerable to skimming and MitM attacks).

Re: POS
We've all seen the futzing first hand...If merchants don't find a more efficient education process than EMV could lose popularity.

Re: POS
@Ryan: Well, that's the whole problem.  That education *shouldn't* fall to the merchants; it should fall to the credit card companies compelling the switch.

But good luck with that.

Re: POS
I hear you, I would say Everybody should be equally responsible credit card company, bank and retail delivery company has to be equally responsible, that would take us to Apple Pay and we will have less troubles.

Re: POS
I've heard some companies that have Apple Pay capabilities ready are not necessarily always active.

IE: stores can use Apple Pay but have yet to set it up. Can anyone add to this?

Re: POS
@Joe. Agreed. I'm not even sure what that might look like in terms of approach. I envision similar to when Apple is teaching people how to use iCloud or BestBuy holds a tech learning session (etc) but instead with EMV?

Re: POS
A simple little one-sheet instruction manual, or email, or pop-up when paying a bill online, or whatnot, could go a long way in educating customers.

Re: POS
I think we should skip EMV and jump to Apple or Google pay directly. It is more secure and convenient.

Re: POS
Apple Pay and Google Pay are not inherently more secure; they just have different security vulnerabilites than EMV (or, for that matter, black-stripe cards).  Lose your device and you're potentially screwed (especially what with easily hackable fingerprint biometrics).  And there may still be viable MitM attacks.

POS Exploitation
It seems that many companies don't take the data threat seriously until they are burnt, especially when it comes to POS...

With the trend of data breaches involving POS, it is irresponsible to handle business as status quo.

Re: POS Exploitation
@Ryan: My feeling is that that's by design -- that many large enterprises have determined the risk worth it compared to the cost.  (Reminds me of how the TJX CIO, prior to their major breach some years back, sent out a memo explicitly saying that it made more budgetary sense to hold off on PCI-DSS compliance -- and outright daring anyone to stand up to him.)

Re: POS Exploitation
Obviously PCI compliance is not optional anymore if you are making business with government or other big companies, they ask their sub-contactors be PCI compliant anymore.

Re: POS Exploitation
@Joe: That's a little brazen on the CIO's part.

And yes it could be part of design...hopefully companies that go down this road have good cyber security insurance and their breach falls under the terms of their policy.

Re: POS Exploitation
Indeed.  I recently gave a talk on cyber insurance and cyber liability issues at MIT, and one of the primary problems we're seeing is that whereas enterprise is getting on board, SMEs feel priced out of the cyber insurance market or otherwise feel that it is inaccessible -- simply because of its complexity.  Alas, SMEs are the ones most deeply impacted by a data loss or data breach.

Re: POS Exploitation
Agree, most POS is old technology so changing it costly but as Target and Hilton realize not changing is apparently more costly.

Dumb POS
Maybe we need to make POS as dumb as possible, so there is a less opportunity to be vulnerability to attacks.

Re: Dumb POS
@Dr. T: Indeed, going back to the old cash registers would certainly make things more secure -- but then would be an obstacle to data collection.

The real problem, typically, is infrastructure.  The Target hack, for instance, was made possible because of the fact that the vendor's HVAC was connected to the same infrastructure as the POS systems were.
