Oh no. Now they know the aliased email address, unique password, and that I didn't try very hard to learn spanish.

(please note: this is a joke, I don't see anything about them getting passwords)

[–] stevedidWHAT@lemmy.world 28 points 1 year ago (19 children)

Something to note here - with AI, if you’re using any sort of heuristic for your password, it’s pretty simple to work out a pretty good set of possibilities which makes brute force even easier and puts you at risk across the board.

Always come up with random passwords that are as random as possible. If there’s a path you took to get to a password, in theory it can be worked backward.

For example I know some people who only change a single letter when changing their passwords which is ultimately trivial to guess if the old password was compromised (hence the need to change the password or the need to proactively work against this possibility)

[–] I_Has_A_Hat@lemmy.ml 38 points 1 year ago (4 children)

I wish more websites allowed random words as passwords instead of forcing numbers and special characters (but not THAT special character, you have to use one of the ones on this list).

People change their passwords by one letter or digit because they're tied to these restrictive formats. If 5-6 random words was the norm, people would update more than just one character when needing to change passwords.

"poison navy series ruler handshake papaya" is a fantastic password.

"Ilovemygrandkids!123" is a horrible password.

[–] hatter@lemmy.world 25 points 1 year ago (1 children)

Just use a password manager and a unique, long, random generated password for every site. There's no need or reason to know the password to anything other than your password manager and your primary email.

[–] deft@ttrpg.network 8 points 1 year ago (1 children)

in like a decade the use of a password manager will be a bad idea. i don't know how but it will be.

[–] demlet@lemmy.world 13 points 1 year ago (2 children)

Hmm, a single point of access for every password you have? I don't see the problem...

[–] SleveMcDichael@programming.dev 19 points 1 year ago* (last edited 1 year ago) (1 children)

The thing is the average person either can't or can't be bothered to remember even a dozen actually secure passwords, so they fall back to a couple of simple derivations of a common password, meaning each and every site a user signs up on represents an additional single point of failure.

[–] demlet@lemmy.world 2 points 1 year ago

That's a good point.

[–] Chriskmee@lemm.ee 10 points 1 year ago

Lucky until we get actual quantum computing, it's not worth the years on a supercomputer to crack a single stolen set of encrypted passwords.

That's why I use IncorrectBatteryHorseStaple

They'll never figure that one out

You immediately know that they're not handling your passwords correctly when they block certain characters.

[–] stevedidWHAT@lemmy.world 5 points 1 year ago

Agreed! I also think that the next steps would be getting rid of the need for users to even know their own password and instead replace with other securities like biometrics (with sufficient permutations possible to match or exceed passwords) and a physical device or something else entirely that removes the need to let the user in on what the exact password is

[–] lobut@lemmy.ca 3 points 1 year ago (1 children)

I use a heuristic to update my main passwords. It's not a character but easily guessable if you see it in plaintext and now you've made me facepalm my actions.

I only use that for certain things because I use Google Oauth or Bitwarden for most things and you've just woken me up about what could be exposed.

[–] stevedidWHAT@lemmy.world 2 points 1 year ago

The goal should usually be as random as possible, if it’s got a series of steps to create, they can be traced backward

Now the trick I’m not telling you is that randomness is hard to get because you need a sufficient amount of entropy (basically just means randomness, chaos, formally it’s how much uncertainty there is in the system) to ensure that it’s strong enough which can be challenging sometimes. For example, if your password is only 3 characters long and has 10 possibilities for each spot in the string, you’re only looking at 10^3 possibilities to guess accurately which is nothing to pcs and people with time on their hands haha

[–] fraydabson@sopuli.xyz 2 points 1 year ago

something I did before letting bitwarden take over my passwords, was using a phrase consisting of 2-3 words + a series of numbers and special characters. Safer than anyone I knew at the time's passwords. Admittedly it was not the most secure, as i only changed the beginning part of the 2-3 word phrase, and left the last word, numbers and symbols the same. So if one of those passwords were breached, it wouldn't be too difficult for AI to brute force the missing pieces. So yeah I don't do that anymore.

Next email from duo: give me your credit card details

"Mi Numero del Seguridad Social es..."

[–] chulo_sinhatche@lemmy.world 44 points 1 year ago (3 children)

Do the people that release these get paid somehow? Or do they just do it for hacker cred and say fuck these 2.6M people?

[–] Dasnap@lemmy.world 45 points 1 year ago (2 children)

In January 2023, someone was selling the scraped data of 2.6 million DuoLingo users on the now-shutdown Breached hacking forum for $1,500.

...

As first spotted by VX-Underground, the scraped 2.6 million user dataset was released yesterday on a new version of the Breached hacking forum for 8 site credits, worth only $2.13.

"Today I have uploaded the Duolingo Scrape for you to download, thanks for reading and enjoy!," reads a post on the hacking forum.

[–] snorkbubs@fedia.io 20 points 1 year ago

This part is also, ummm, interesting...

BleepingComputer has confirmed that this API is still openly available to anyone on the web, even after its abuse was reported to DuoLingo in January.

[–] Chariotwheel@kbin.social 20 points 1 year ago

HODL, the value will go up again for sure

[–] ChaoticNeutralCzech@feddit.de 26 points 1 year ago (1 children)

They’ll send fake emails where the green owl comes to collect “late fees” for your 216-day streak of missed Spanish lessons.

[–] elvith@feddit.de 24 points 1 year ago

We've been trying to reach you about your language course's extended warranty...

[–] SpicaNucifera@lemm.ee 40 points 1 year ago (2 children)

Oh no, not my German and Japanese scores!!!

I guess the email could become a spam target?? Gmail does a good job sorting that for me.

[–] themeatbridge@lemmy.world 25 points 1 year ago

They know your email, your name, and that you've taken German anf Japanese. Next they use that information to craft a phishing email that only the very stupid would fall for, which fools an alarming number of people. Something like "Hi, this is Duolingo suppert, and your billing information may have been comprimised. Log into this portal with your credit card credentials to confirm that you were not affected."

"Scraped" data suggests that it's data available on public profile pages. However, the article also says the dump is a mix of public and non-public info. So which is it, scraped or not? It's an important distinction, because data collection by scraping is technically not a breach.

I pray for whoever pisses off the duolingo bird

[–] Destragras@kbin.social 11 points 1 year ago (1 children)

How is that API still up after this has happened?

[–] AToM_exe@lemmy.world 2 points 1 year ago (3 children)

I only see this comment, but it says 53 comments. I just want to know why they didn't tell their userbase.

[–] stopthatgirl7@kbin.social 3 points 1 year ago

Lemmy and kbin have been having some federation issues lately, which might be why you’re only seeing one comment.

[–] s1ndr0m3@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

I see the same thing. However if you go to the link to this post on kbin.social, you can see the other comments. It's weird. https://kbin.social/m/technology@lemmy.world/t/371933 Edit: the hyperlink won't display properly in this comment. You have to copy the whole link and paste it in your browser.

Is there a list on what data exactly got leaked, that wasn't public before?

[–] ansik@kbin.social 23 points 1 year ago* (last edited 1 year ago) (1 children)

However, Duolingo did not address the fact that email addresses were also listed in the data, which is not public information.

From the Article, emphasis by me

[–] DragonTypeWyvern@literature.cafe 10 points 1 year ago* (last edited 1 year ago)

Rip my email I use specifically for organizations I don't trust

[–] z4x15@lemmy.world 7 points 1 year ago (1 children)

I'm so glad I switched to duck email. Might as well changes it again and block the old email.

[–] Unsustainable@lemmy.today 5 points 1 year ago (6 children)

DDG email is AMAZING! I only wish it would have been around before my email got exposed.

[–] fox@unilem.org 4 points 1 year ago (5 children)

Only one thing to do... Start over fresh.

I just did this a few months ago, and it feels really good to have a proper set-up now, with privacy respecting companies all around.
