isFirstSuccessfulLoginAttempt

Important distinction.

[–] dalekcaan@feddit.nl 35 points 2 months ago (4 children)

Yeah, as it is it only works if the brute force algorithm gets it on the first try.

[–] atopi@piefed.blahaj.zone 13 points 2 months ago

Or the variables are terribly named

[–] Jimbabwe@lemmy.world 4 points 2 months ago (1 children)

Boho sort is O(1) in the best case scenario

[–] sga@piefed.social 1 points 2 months ago (1 children)

i guess you mean bogo sort? just verifying that output is sorted requires O(n). In Quantum bogo sort, you can skip verification.

[–] Jimbabwe@lemmy.world 2 points 2 months ago (1 children)

Yeah, stupid autocorrect. And verifying ain’t the same as doing. I’ll come in, I’ll “sort” your data, and I’ll do it damn fast. You want verification that’s extra!

[–] sga@piefed.social 2 points 2 months ago (1 children)

but how do you know you are done. maybe there are different ideas of what bogo sort is, but as i remember, it is basically a while true (or while false loop) with condition - while list_is_not_sorted { return_a_random_ordering }

[–] Jimbabwe@lemmy.world 1 points 2 months ago

Yeah but I said in the best case. In the best case, your randomization is correct so you don’t need to check it

[–] TheseusNow@lemmy.zip 1 points 2 months ago

Not even then. Brute force cracking programs don't rely on the server to indicate if the attempted password is correct.

[–] Simulation6@sopuli.xyz 0 points 2 months ago

No, it just means you have to type in the correct password twice in a row.

  SessionSuccessfulLogins == 1
[–] Johanno@feddit.org 40 points 2 months ago (1 children)

Even worse the silent invalidation of a correct password.

Use password manager.

Can't log in, because "password is incorrect"... Fuck you! It is not! I copied in the same fucking thing as months before! If you want to force me to change it then say it! Asshole!

[–] mckean@programming.dev 5 points 2 months ago

sorry, but your new password cannot be the same as your current one.

[–] falseWhite@lemmy.world 19 points 2 months ago

I swear Microsoft does that.

[–] snooggums@piefed.world 17 points 2 months ago (4 children)

How does this 'kinda work'?

[–] MyTurtleSwimsUpsideDown@fedia.io 80 points 2 months ago (1 children)

It rejects the first [correct] login attempt (it’s worded poorly). It assumes that a brute force attacker will try any given password once and move on, while a human user will think they made a typo and try again. This works until the attacker realizes that it takes two attempts, in which case it merely doubles the attempts required to breach the account, and simply requiring an additional password character would be vastly more effective.

[–] snooggums@piefed.world 40 points 2 months ago (5 children)

What a shitty user experience for regular users.

[–] dreadbeef@lemmy.dbzer0.com 100 points 2 months ago (1 children)

which is why they made a comic instead of a revolutionary thought leading blog post

[–] taiyang@lemmy.world 15 points 2 months ago

Hey now, I'm sure there's someone on LinkedIn suggesting this exact thing with layers of corporate speak.

[–] ICastFist@programming.dev 17 points 2 months ago

Just like captcha

[–] MyTurtleSwimsUpsideDown@fedia.io 16 points 2 months ago

Agreed, and also makes it readily known that that is what you are doing.

The sneakier more user friendly way to implement it would be to require the second correct attempt only if the user has made an incorrect attempt since the last successful login.

[–] Smoogs@lemmy.world 4 points 2 months ago

Yup it’s like how software companies will get a hate on for pirates and take it out on their loyal paying cutosmers

[–] petersr@lemmy.world 4 points 2 months ago

Look, we all need to pay a little for the greater good of security.

[–] black0ut@pawb.social 23 points 2 months ago

All tools that bruteforce passwords attempt each password only once, and if it doesn't work, discard it. Nobody really runs 2 identical attacks back to back (they're incredibly slow when done over the internet), so the password would seem uncrackable at first glance.

This approach wouldn't work with hash cracking, vault breaking or file encryption, because once they get their hands on the hash/vault/file, the attacker can use their own code for hashing/checking a password candidate.

[–] Kolanaki@pawb.social 6 points 2 months ago (1 children)

They'll change the correct password every time because they are told it is wrong.

[–] MonkeMischief@lemmy.today 2 points 2 months ago

Don't worry, a not-insignificant number of users probably use "Forgot Password?" every time because they can't keep track of the correct one. Lol

I suspect this is why we started to see all those "use a temporary password instead" options lately. XD

[–] TheseusNow@lemmy.zip 5 points 2 months ago (1 children)

It doesn't. Cracking programs don't use the user login form repeatedly. They use the same algorithm that creates the publicly encoded password to generate encoded passwords and keep going until they have a match. Besides getting the encoded password and salt, everything is done offline.

This just creates a really bad user experience.

[–] camelbeard@lemmy.world 2 points 2 months ago

If they actually use the real login form, most websites block an account after X attempts. Sometimes for 1-24 hours, sometimes until you do a PW reset

[–] laserm@lemmy.world 9 points 2 months ago (1 children)

At least make it if !isPasswordCorrect || isFirstTry

[–] Samskara@sh.itjust.works 0 points 2 months ago

guard isFirstAttempt { return LoginError(); }

[–] blockheadjt@sh.itjust.works 8 points 2 months ago

Center guy's hair got visibly lighter from the stress

Is this Tron: Ares?

The only part that works is that I get to keep my trust issues.
