Financial institutions are very slow to adopt new tech. Especially tech that will inevitably cost $$$ in support hours when users start locking themselves out of their accounts. There is little to no advantage to being the first bank to implement YubiKey 2FA. To a risk-averse org, the non-zero chance of a botched rollout or displeased customers outweighs any potential benefit.

They're pretty terrible when they do.

For the longest time the max password size was 8 characters and the csr knew what your password was.

Heck I've had Chase security tell me they'd call me back.. dude that's exactly how people get compromised.

A friensd bank, hopefully not the one i use, only allow a password off 6 digits. Yes You read it right, 6 fucking digits to login, i hace him the asvice to run away from that shitty bank
Did this bank start out as a "telephone bank"? One of the largest German consumer banks still does this because they were the first "direct bank" without locations and typing in digits on the telephone pad was the most secure way of authenticating without telling the "bank teller" your password. So it was actually a good security measure but it is apparently too complicated to update their backend to modern standards.

They do require 2FA, though.

DiBa?
Exactly. 8 character password in the 2010s as the only factor was fine. It was only my money we're talking about.

Now I have to wait for an SMS. Great...

SMS is fine on most countries. It’s just America is dumb and allows number transfers to anyone.
Nope, I read The Register (UK based) and they've had scandals from celebrities having their confidential SMS messages leaked; SMS spoofing; I think they even have SIM cloning going on every now and then in UK and some European countries. (since The Register is a tech site, my recollection is some carriers took technical measures to prevent these issues while quite a few didn't.)

I don't think it's a thing that happens that often in UK etc.; but, it doesn't happen that frequently in the US either. It's just a thing that can potentially happen.

UK has plenty of other problems to solve first with identity thief.
...where identity is proved by utility bills instead of government issued id
How else do you prove you live some place?

“I pay the bills there” is barely better than nothing, though. We do this in Canada too. It is what I used for a driver’s license one renewal.

SS7 is a global issue, and so is social engineering to get a number transferred or SIM card transferred.

Its also been a problem in Australia, Optus (2nd biggest teleco) used to allow number porting or activating sim against an existing account with a bare minimum of detail - Like a name, address and date of birth. If you had those details of a target you could clone their SIM and crack any SMS based MFA.
Is that alllowed now still?
Apparently changed in 2022 to protect consumers.
I don’t know about other parts, but here in France SMS is a shitshow. I regularly fail to receive them even though I know I have good reception.

This happened the other day while I was on a conference call with perfect audio and video using my phone’s mobile data.

A few weeks back, had some shop which sends out an SMS to inform you the job’s done tell me this is usually hit and miss when I complained about not hearing from them.

Many single radio phones can either receive sms/calls, or transmit data. My relative owns such a device and cannot use internet during calls or receive/make calls during streaming like YT video playback.
In my case this is an iPhone 14 pro. I'm pretty sure I can receive calls while using data, since I often look things up on the internet while talking to my parents.

And, by the way, the SMS in question never arrived. I don't know if there's some kind of timeout happening, and the network gives up after a while. Some 15 years ago I remember getting texts after an hour or two if I only had spotty reception. This may of course have changed in the meantime, plus this is a different provider.

SMS is not E2E encrypted, so for all intents is just a plain text message that can/has been snooped. Might as well just send a plaintext emails as well.
Number transfers in other countries is also mostly just a question of a bit of social engineering.
No. Most require some form of identification or matching identification between mobile providers.
I recently had an issue with a sim card and went to phone store that gave me a new one and disabled the old. They're supposed to ask for ID, but often doesn't bother. This is true for pretty much every country. Phone 2FA is simply completely insecure.
If the ID matching is done by humans, you can use social engineering on it.

See the sibling comment.

Ideally they’d just implement passkeys (webauthn/fido). More secure, and it works with iOS, android, 1password, and yubikeys

Uh many banks provide MFA. And secure with hardware keys. It’s just that your level of assets doesn’t warrant that kind of protection.

Source: worked at all the major banks, all the wealthy clients use hardware MFA

The bank I used in The Netherlands provides a MFA device as well. The device requires an ATM card as well to generate a random number.

This is the default for all their customers, wealthy or not.

I meant to say in the us :)
They’re a bank. If they can secure their portals with hardware keys, at least allow customers to onboard their own keys.
My bank gave me an hardware token to protect my 5k€ account.

Get better banks people :)

I meant to say in the us. You know how backwards we are here :)
