Shellshock and the Cyber Safety Program standard

I recently had a conversation with Josh Corman of IAmTheCavalry where he shared with me his open letter to the automotive industry. Entitled, the Five Star Automotive Safety Program, it outlines five specific areas that affect information security, and thus will affect the safety of humans that rely on those systems. The five areas are: Safety by Design Third-Party Collaboration Evidence Capture Security Updates Segmentation & Isolation When Josh and I first chatted, I was wary of number 4. Not the fact that security updates are needed, but that there must be a mechanism by which updates can be automatically deployed (not by taking a car to the repair shop). Could someone create a cyber-zombie army by taking over an ...

Apple Pay is Not P2PE, and Does Not Replace PCI Compliance standard

Apple Pay’s announcement two weeks ago caused a flurry of activity—some of it right here on this blog. I had a chance to catch up with someone who is very close to the design of Apple Pay. I was able to get a few questions answered and I wanted to share those answers here with you all. Apple Pay’s NFC uses EMV. EMV is a standard which was implemented in both the chip and contactless variants for payments. It is effectively the first wide-scale system that uses the EMV Token standard released this year. Apple Pay is software that uses the NFC radio built into the iPhone 6/6+. Why did I make this distinction? Each technology (for example, PayWave and ...

Side Channel Attacks for PINs standard

I found this Lifehacker post this week and I am totally loving the demonstration he gives in his video. Anyone who has watched a crime drama knows that people are filthy beings that leave traces of themselves wherever they go. It could be DNA from skin cells or hair, prints from our shoes, or a heat signature from touching something. In the video, Mark Rober shows you how an iPhone attachment can pick up the PIN code you just entered into a terminal to pay for goods and services. He even gives you some ideas on how to avoid getting hit. For those of us that saw Bob Arno at the Community meeting last week and saw the coordinated shoulder ...

Does Apple Pay Signal the Beginning of the End of PCI? standard

Whether you are a fanboy or not, you have probably seen some news about Apple’s new Apple Pay feature in the iPhone 6. It appears that the sleeping giant of digital wallets is stirring from his slumber. Could this spell the end of PCI DSS for the majority of companies affected by the standard? The last few decades have seen a number of companies attempting to disrupt or revolutionize payments, but like the payment card brands themselves, they battled acceptance. Apple’s new iPhone 6 finally has Near Field Communication (NFC) built into the device, which means it can now interact with contact-less payment card readers. The dream of leaving your house with only your phone is not quite a reality ...

Why won’t you change your password? standard

There was a very interesting post by Punam Keller last week on the HBR Blog Network on the psychology of passwords. This isn’t like the previous posts you have seen on this blog. While I tend to focus on the technical problems and ways around them, Keller explores the behavioral aspects of passwords and our general resistance to do what we all know is right. She highlights four attitudes that people have when it comes to passwords: People who don’t know they should change their passwords—most likely by intentionally ignoring information that indicates they should. People who know they should change it, but avoid doing it because they think password theft and misuse will happen to someone else. People who ...

Don’t Listen to this ConsumerReports Advice standard

Lifehacker recently posted something from ConsumerReports where an author suggested asking a hotel manager for their [PCI DSS] Attestation of Compliance. Asking someone for an AoC is en exercise in futility. There is one piece of advice that is good (use credit not debit), but the constructs of asking for an AoC is really not good advice. There are a number of reasons for this. Many hotels with your favorite brands are actually smaller properties owned and operated by individual owners. Even if they have an AoC, it’s probably done from the perspective of a Self Assessment Questionnaire which does not require a third party to review. I promise you that the vast majority of front desk clerks and managers ...

More Fun with EMV standard

Yes, it’s time to go hit your local university library again (or just join the Association for Computing Machinery) to see a great article from Anderson & Murdoch entitled, “Inside Risks EMV: Why Payment Systems Fail.” For those of us in the US that are now on the cusp of a wide-scale EMV rollout, there are still many questions that need to be answered. Drs. Anderson and Murdoch do a great job of summarizing the issues that we will face here in the US, including some of the attacks that were common in other implementations of EMV. Turns out, the French may be the best experts at cracking this thing. EMV tokens make an appearance in the article, but there ...

EMV as an E-Commerce Fraud Driver standard

Oh what a year it has been so far. Breach here, breach there, breaches everywhere! EMV to the rescue, right? RIGHT?!? Well, yes and no. EMV does add tremendous security (when configured properly) to a Card Present (CP) transaction, but EMV does nothing to help the security of Card Not Present (CNP) transactions. And given the increased digitization of business and commerce, we would expect that over time the number of CNP transactions would increase at the expense of CP transactions. Meaning, as more digital business models drive people to purchase goods and services without physically presenting their card for purchase, people will opt for that style as it could be seen as more convenient. Don’t forget that CNP transactions ...

Heartbleed and Passwords standard

Right around this same time last week there was a flurry of activity for those responsible for deployments leveraging OpenSSL. Yep, I’m talking about Heartbleed. So after we go through all of the patching and re-keying, it’s now time to consider password changes. This post isn’t about Heartbleed, it’s about passwords and what the bad guys already know. Melanie Pinola from Lifehacker wrote a very interesting piece on Friday about how our password tricks don’t fool the modern hacker. I’m not sure what happened to recommendation number 3 in her piece, 1, 2, and 4 are spot on. What’s the solution? Ultimately it comes down to using some software to help you out. Password managers are now built into some ...

For the Super Geeky Crypto Guys standard

Of course, if you are a super geeky crypto guy (in which I am envious because math is not my strong suit) you probably already saw this amazing paper by Daniel Genkin, Adi Shamir (the S in RSA), and Eran Tromer in which they prove a side-channel attack against RSA encryption. Since the math behind RSA is such that decryption becomes infeasible through brute force, attackers must get creative in how they go after the protocol. Previous attacks on prime number generation have been published, as well as weak implementations of software that leak parts of the key. But this one is really ingenious. The authors are able to extract the RSA key by simply listening to the noise put ...
