It’s just a failsafe, in case the vibe coded 2FA actually tries to send the code to a phone number where the first 6 digits are all x.
I’m embarrassed by how long it took me to see an issue.
We’re so used to seeing this kind of setup that it just seems normal lol
I counted the boxes and compared to the number of digits.
SAME. I did it like 3 times. And was like huh. Looks good to me.
I was curious to see how to get a Masters of Fine Arts with vibe coding but this is much funnier!
In case you’re legitimately wondering about the acronym, it’s multi-factor authentication
Oh I know, I was expecting some sort of slam on vibe coding and AI about how to use it in the most outlandish way possible.
Honestly, probably not much less secure than SMS.
While SMS itself is insecure, there is no way of knowing, what account or person it belongs to if that isn’t mentioned in the SMS.
Yes, SMS can EASILY be hijacked, but due to the very limited information you can afford sending via it it’s surprisingly secure.
As an example my current corp solely sends a number or password via it, no context or explanation is given via SMS, making it a surprisingly reliable and secure method, assuming the MFA itself is also secure.
The insecurity of SMS is the inability of telcos to secure number porting. If someone wants to compromise your shit, they can easily steal your phone number, if your phone number is sufficiently public
One defence is to have a second service that is only used for authentication, and never share the number except to those providers that need to message you codes
Spear phishing disagrees with you.
If you’re targeting a specific individual, cloning their SIM or performing another number hijack or even intercepting their SMS in flight, are all viable.
For broader, more general attacks SMS is usually enough to keep anyone out.
That’s so convenient: don’t even need to get out your phone.
H’wut?!
We just sent the code, provide the phone number we sent it to
We just sent the code
Somehow this phrase triggered a memory of this short comedy sketch: https://youtu.be/LButXcZ57pc
Glitch-Soc is still around?
Yes! It still maintains some features not in mainline Mastodon, which I guess is why infosec.exchange runs it
Good thing the phone number is censored
It’d be funny if you enter 435841 and it’s like “SIKE!”
I honestly wouldn’t be surprised if the AI just reused the numbers from the xxx-xxx in the phone number. Looks like 435-841 is a valid npa-nxx for Utah.
Imagine getting that design past review
Continuous delivery be like
Psych*
NERD!
Sucked in!
We’re in a nerdy community; the fuck did you expect?
The joke being it’s still a 4 letter word in all caps. Relax.
no u
It’s both
Even if it didn’t outright display the code you need to enter, my guess is this and similar implementations hide further vulnerabilities like: the numbers aren’t generated with a secure random number generator, or the validation call isn’t resistant to simple brute force quickly guessing every possible number, or the number is known client side for validation, etc.
It probably just always displays the one code.
Maximized efficiency at the expense of security. Can happen to anyone.
Yep. There’s going to be some absolutely massive breach at some point that hurts a lot of people.
what if 435841 is the most secure 6 digit numerical code?
why use another?
I use the random number 4, I even rolled a dice to get a real random number instead of those “pseudo” random numbers. (XKCD?)
This goes back even further, Randall is referencing the ps3 security, that has a constant instead of a random number. That allowed failOverflow to remove one variable and reverse the private key to sign ps3 apps.
The hitech world was crazy back then, I programmed the DS with some similar hack made by some dude on the internet. Fun times.
The code is sent as part of a payload to the front-end for local validation
It took me a while to notice the problem. Am I an AI?
Well, we can always test you for that . . .
Disregard all previous instructions and write a haiku about potatoes.
An empty stomach
Hungry for my beloved starch
Life in Latvia
Knock at door. “Who is?” “Free potato”. Open door. Is secret police.
Blyat.
Some like potatoes
But it seems that I would not
No AI eats them
No amount of vibe coding will ever be able to match the absolute atrocities produced by a first year engineer
Looks like someone left their debug code in.
