Why is 2FA SMS OTA NBG?

xxx

The National Fraud Intelligence Bureau (NFIB) and one of the UK’s largest mobile phone networks, EE, have raised concerns about banks’ growing reliance on text messages when authorising large payments.

FBI turns up the heat on banks over Sim scams | Money | The Sunday Times:

I seem to remember first raising concerns about the banks’ use of text message for authorisation about a decade ago, but no-one ever listens to me. Of, it appears, anyone else who has said this over the last ten years or so.

Now, I’m not saying that no banks at all have listened to the cacophony of security experts telling them not to use text messaging for a purpose for which is was never intended. Earlier this year, German banks dropped support for SMS -based OTP as 2FA for SCA in PSD2 .

 

In the UK, it’s the mobile operators who have taken action. They have created something call “SMS Phishguard” which means that (I think) fraudsters will not be able to ‘spoof’ numbers so that bogus texts appear to be sent from a real bank.

Financial Cryptography: Corda Day - a new force

Forum friend Ian Grigg, who I always take very seriously indeed on any such topic, wrote about Corda on his blog and concluded with a powerful statement. Bitcoin told the users it wanted an unstoppable currency - sure, works for a small group but not for the mass market. Ethereum told their users they need an unstoppable machine - which worked how spectacularly with the DAO? Not. What. We. Wanted. Corda is the only game in town because it's the only one that asked the users. It's that simple. From Financial Cryptography: Corda Day - a new force xxx It seems to me, however, what Ian is pointing to as the greatest strength of their approach is also the greatest weakness. A staple feature of unimaginative management consultants presentations about innovation is some variation on the statement by Henry Ford that if you had asked users what they wanted, they would have asked for faster horses coupled with some variation on the statement by Steve jobs that it was pointless ask...

Barclays slated after CIO takes a year to open a bank account

xxx The rigorous KYC procedures at US banks the New Jersey-based crime ring created more than 7,000 fake identities to get tens of thousands of credit cards From  Woman Gets 3 Years for Role in $200M Credit Card Fraud Scam - ABC News xxx xxxx Barclays slated after CIO takes a year to open a bank account : "An adviser to a new charitable incorporated organisation that spent more than a year trying to open a bank account has blasted Barclays for its onerous demands and disproportionate due diligence." xxx In a recent survey for VocaLink, some two-thirds of respondents said that they saw value in the establishment of a central KYC utility. They are wrong. We don’t need a central KYC utility, we need a federated reputation infrastructure. Or, to put it another way, a financial services passport ( as I mentioned earlier in the year ).

We could fix mobile security, you know. We don't, but we could

Earlier in the week I blogged about mobile banking security , and I said that in design terms it is best to assume that the internet is in the hands of your enemies. In case you think I was exaggerating… The thieves also provided “free” wireless connections in public places to secretly mine users’ personal information. From Gone in minutes: Chinese cybertheft gangs mine smartphones for bank card data | South China Morning Post Personally, I always use an SSL VPN when connected by wifi (even at home!) but I doubt that most people would ever go to this trouble or take the time to configure a VPN and such like. Anyway, the point is that the internet isn’t secure. And actually SMS isn’t much better, which is why it shouldn’t really be used for securing anything as important as home banking. The report also described how gangs stole mobile security codes – which banks automatically send to card holders’ registered mobile phones to verify online transactions – by using either a Trojan...
