Looks like someone left their debug code in.
It took me a while to notice the problem. Am I an AI?
No amount of vibe coding will ever be able to match the absolute atrocities produced by a first year engineer
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.
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.
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.
The code is sent as part of a payload to the front-end for local validation
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.
It probably just always displays the one code.
Yep. There’s going to be some absolutely massive breach at some point that hurts a lot of people.
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’ve seen very similar in the wild, the webapp would sendo a requet to the API with the numbers so that the captcha imagem was generated
I’m a fan of AI, I know that’s unpopular here but I think it’s a cool tool.
But you need to know what you are doing and how to program. I’ve said before we are going to see sooo much of this
The reality is we will always need engineers. Certainly not ready yet, but we probably won’t always need “programmers” - which is a shame because I do get a kick out of solving a really complex problem in a super elegant way
AI is a tool like any other. I wouldn’t turn on a power tool, set it down in a construction site, and expect everything to be done the next day.
Copilot saves a lot of time and mental load. I’d never let it vibe code, though. Suggesting is all it gets to do.
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
That’s so convenient: don’t even need to get out your phone.
Glitch-Soc is still around?
Yes! It still maintains some features not in mainline Mastodon, which I guess is why infosec.exchange runs it
It’d be funny if you enter 435841 and it’s like “SIKE!”
Psych*
It’s both
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
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.
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.
I love it, hate having to check my phone for these, brilliant choice to put the code onscreen
